This + function is called very early, usually at the start of the + platform's entry function (e.g. main or WinMain). You should do as + little as possible here, since the rest of your code might be called + from another thread (this depends on the platform): + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + .width = 640, + .height = 480, + .init_cb = my_init_func, + .frame_cb = my_frame_func, + .cleanup_cb = my_cleanup_func, + .event_cb = my_event_func, + ... + }; + } + + There are many more setup parameters, but these are the most important. + For a complete list search for the sapp_desc structure declaration + below. + + DO NOT call any sokol-app function from inside sokol_main(), since + sokol-app will not be initialized at this point. + + The .width and .height parameters are the preferred size of the 3D + rendering canvas. The actual size may differ from this depending on + platform and other circumstances. Also the canvas size may change at + any time (for instance when the user resizes the application window, + or rotates the mobile device). You can just keep .width and .height + zero-initialized to open a default-sized window (what "default-size" + exactly means is platform-specific, but usually it's a size that covers + most of, but not all, of the display). + + All provided function callbacks will be called from the same thread, + but this may be different from the thread where sokol_main() was called. + + .init_cb (void (*)(void)) + This function is called once after the application window, + 3D rendering context and swap chain have been created. The + function takes no arguments and has no return value. + .frame_cb (void (*)(void)) + This is the per-frame callback, which is usually called 60 + times per second. This is where your application would update + most of its state and perform all rendering. + .cleanup_cb (void (*)(void)) + The cleanup callback is called once right before the application + quits. + .event_cb (void (*)(const sapp_event* event)) + The event callback is mainly for input handling, but is also + used to communicate other types of events to the application. Keep the + event_cb struct member zero-initialized if your application doesn't require + event handling. + .fail_cb (void (*)(const char* msg)) + The fail callback is called when a fatal error is encountered + during start which doesn't allow the program to continue. + Providing a callback here gives you a chance to show an error message + to the user. The default behaviour is SAPP_LOG(msg) + + As you can see, those 'standard callbacks' don't have a user_data + argument, so any data that needs to be preserved between callbacks + must live in global variables. If keeping state in global variables + is not an option, there's an alternative set of callbacks with + an additional user_data pointer argument: + + .user_data (void*) + The user-data argument for the callbacks below + .init_userdata_cb (void (*)(void* user_data)) + .frame_userdata_cb (void (*)(void* user_data)) + .cleanup_userdata_cb (void (*)(void* user_data)) + .event_userdata_cb (void(*)(const sapp_event* event, void* user_data)) + .fail_userdata_cb (void(*)(const char* msg, void* user_data)) + These are the user-data versions of the callback functions. You + can mix those with the standard callbacks that don't have the + user_data argument. + + The function sapp_userdata() can be used to query the user_data + pointer provided in the sapp_desc struct. + + You can also call sapp_query_desc() to get a copy of the + original sapp_desc structure. + + NOTE that there's also an alternative compile mode where sokol_app.h + doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY. + + --- Implement the initialization callback function (init_cb), this is called + once after the rendering surface, 3D API and swap chain have been + initialized by sokol_app. All sokol-app functions can be called + from inside the initialization callback, the most useful functions + at this point are: + + int sapp_width(void) + int sapp_height(void) + Returns the current width and height of the default framebuffer in pixels, + this may change from one frame to the next, and it may be different + from the initial size provided in the sapp_desc struct. + + float sapp_widthf(void) + float sapp_heightf(void) + These are alternatives to sapp_width() and sapp_height() which return + the default framebuffer size as float values instead of integer. This + may help to prevent casting back and forth between int and float + in more strongly typed languages than C and C++. + + double sapp_frame_duration(void) + Returns the frame duration in seconds averaged over a number of + frames to smooth out any jittering spikes. + + int sapp_color_format(void) + int sapp_depth_format(void) + The color and depth-stencil pixelformats of the default framebuffer, + as integer values which are compatible with sokol-gfx's + sg_pixel_format enum (so that they can be plugged directly in places + where sg_pixel_format is expected). Possible values are: + + 23 == SG_PIXELFORMAT_RGBA8 + 27 == SG_PIXELFORMAT_BGRA8 + 41 == SG_PIXELFORMAT_DEPTH + 42 == SG_PIXELFORMAT_DEPTH_STENCIL + + int sapp_sample_count(void) + Return the MSAA sample count of the default framebuffer. + + bool sapp_gles2(void) + Returns true if a GLES2 or WebGL context has been created. This + is useful when a GLES3/WebGL2 context was requested but is not + available so that sokol_app.h had to fallback to GLES2/WebGL. + + const void* sapp_metal_get_device(void) + const void* sapp_metal_get_renderpass_descriptor(void) + const void* sapp_metal_get_drawable(void) + If the Metal backend has been selected, these functions return pointers + to various Metal API objects required for rendering, otherwise + they return a null pointer. These void pointers are actually + Objective-C ids converted with a (ARC) __bridge cast so that + the ids can be tunnel through C code. Also note that the returned + pointers to the renderpass-descriptor and drawable may change from one + frame to the next, only the Metal device object is guaranteed to + stay the same. + + const void* sapp_macos_get_window(void) + On macOS, get the NSWindow object pointer, otherwise a null pointer. + Before being used as Objective-C object, the void* must be converted + back with a (ARC) __bridge cast. + + const void* sapp_ios_get_window(void) + On iOS, get the UIWindow object pointer, otherwise a null pointer. + Before being used as Objective-C object, the void* must be converted + back with a (ARC) __bridge cast. + + const void* sapp_win32_get_hwnd(void) + On Windows, get the window's HWND, otherwise a null pointer. The + HWND has been cast to a void pointer in order to be tunneled + through code which doesn't include Windows.h. + + const void* sapp_d3d11_get_device(void) + const void* sapp_d3d11_get_device_context(void) + const void* sapp_d3d11_get_render_target_view(void) + const void* sapp_d3d11_get_depth_stencil_view(void) + Similar to the sapp_metal_* functions, the sapp_d3d11_* functions + return pointers to D3D11 API objects required for rendering, + only if the D3D11 backend has been selected. Otherwise they + return a null pointer. Note that the returned pointers to the + render-target-view and depth-stencil-view may change from one + frame to the next! + + const void* sapp_wgpu_get_device(void) + const void* sapp_wgpu_get_render_view(void) + const void* sapp_wgpu_get_resolve_view(void) + const void* sapp_wgpu_get_depth_stencil_view(void) + These are the WebGPU-specific functions to get the WebGPU + objects and values required for rendering. If sokol_app.h + is not compiled with SOKOL_WGPU, these functions return null. + + const void* sapp_android_get_native_activity(void); + On Android, get the native activity ANativeActivity pointer, otherwise + a null pointer. + + --- Implement the frame-callback function, this function will be called + on the same thread as the init callback, but might be on a different + thread than the sokol_main() function. Note that the size of + the rendering framebuffer might have changed since the frame callback + was called last. Call the functions sapp_width() and sapp_height() + each frame to get the current size. + + --- Optionally implement the event-callback to handle input events. + sokol-app provides the following type of input events: + - a 'virtual key' was pressed down or released + - a single text character was entered (provided as UTF-32 code point) + - a mouse button was pressed down or released (left, right, middle) + - mouse-wheel or 2D scrolling events + - the mouse was moved + - the mouse has entered or left the application window boundaries + - low-level, portable multi-touch events (began, moved, ended, cancelled) + - the application window was resized, iconified or restored + - the application was suspended or restored (on mobile platforms) + - the user or application code has asked to quit the application + - a string was pasted to the system clipboard + - one or more files have been dropped onto the application window + + To explicitly 'consume' an event and prevent that the event is + forwarded for further handling to the operating system, call + sapp_consume_event() from inside the event handler (NOTE that + this behaviour is currently only implemented for some HTML5 + events, support for other platforms and event types will + be added as needed, please open a github ticket and/or provide + a PR if needed). + + NOTE: Do *not* call any 3D API rendering functions in the event + callback function, since the 3D API context may not be active when the + event callback is called (it may work on some platforms and 3D APIs, + but not others, and the exact behaviour may change between + sokol-app versions). + + --- Implement the cleanup-callback function, this is called once + after the user quits the application (see the section + "APPLICATION QUIT" for detailed information on quitting + behaviour, and how to intercept a pending quit - for instance to show a + "Really Quit?" dialog box). Note that the cleanup-callback isn't + guaranteed to be called on the web and mobile platforms. + + MOUSE CURSOR TYPE AND VISIBILITY + ================================ + You can show and hide the mouse cursor with + + void sapp_show_mouse(bool show) + + And to get the current shown status: + + bool sapp_mouse_shown(void) + + NOTE that hiding the mouse cursor is different and independent from + the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when + active (MOUSE LOCK is described below). + + To change the mouse cursor to one of several predefined types, call + the function: + + void sapp_set_mouse_cursor(sapp_mouse_cursor cursor) + + Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore + the standard look. + + To get the currently active mouse cursor type, call: + + sapp_mouse_cursor sapp_get_mouse_cursor(void) + + MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE) + ================================================ + In normal mouse mode, no mouse movement events are reported when the + mouse leaves the windows client area or hits the screen border (whether + it's one or the other depends on the platform), and the mouse move events + (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in + framebuffer pixels in the sapp_event items mouse_x and mouse_y, and + relative movement in framebuffer pixels in the sapp_event items mouse_dx + and mouse_dy. + + To get continuous mouse movement (also when the mouse leaves the window + client area or hits the screen border), activate mouse-lock mode + by calling: + + sapp_lock_mouse(true) + + When mouse lock is activated, the mouse pointer is hidden, the + reported absolute mouse position (sapp_event.mouse_x/y) appears + frozen, and the relative mouse movement in sapp_event.mouse_dx/dy + no longer has a direct relation to framebuffer pixels but instead + uses "raw mouse input" (what "raw mouse input" exactly means also + differs by platform). + + To deactivate mouse lock and return to normal mouse mode, call + + sapp_lock_mouse(false) + + And finally, to check if mouse lock is currently active, call + + if (sapp_mouse_locked()) { ... } + + On native platforms, the sapp_lock_mouse() and sapp_mouse_locked() + functions work as expected (mouse lock is activated or deactivated + immediately when sapp_lock_mouse() is called, and sapp_mouse_locked() + also immediately returns the new state after sapp_lock_mouse() + is called. + + On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave + differently, as dictated by the limitations of the HTML5 Pointer Lock API: + + - sapp_lock_mouse(true) can be called at any time, but it will + only take effect in a 'short-lived input event handler of a specific + type', meaning when one of the following events happens: + - SAPP_EVENTTYPE_MOUSE_DOWN + - SAPP_EVENTTYPE_MOUSE_UP + - SAPP_EVENTTYPE_MOUSE_SCROLL + - SAPP_EVENTTYPE_KEY_UP + - SAPP_EVENTTYPE_KEY_DOWN + - The mouse lock/unlock action on the web platform is asynchronous, + this means that sapp_mouse_locked() won't immediately return + the new status after calling sapp_lock_mouse(), instead the + reported status will only change when the pointer lock has actually + been activated or deactivated in the browser. + - On the web, mouse lock can be deactivated by the user at any time + by pressing the Esc key. When this happens, sokol_app.h behaves + the same as if sapp_lock_mouse(false) is called. + + For things like camera manipulation it's most straightforward to lock + and unlock the mouse right from the sokol_app.h event handler, for + instance the following code enters and leaves mouse lock when the + left mouse button is pressed and released, and then uses the relative + movement information to manipulate a camera (taken from the + cgltf-sapp.c sample in the sokol-samples repository + at https://github.com/floooh/sokol-samples): + + static void input(const sapp_event* ev) { + switch (ev->type) { + case SAPP_EVENTTYPE_MOUSE_DOWN: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(true); + } + break; + + case SAPP_EVENTTYPE_MOUSE_UP: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(false); + } + break; + + case SAPP_EVENTTYPE_MOUSE_MOVE: + if (sapp_mouse_locked()) { + cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f); + } + break; + + default: + break; + } + } + + CLIPBOARD SUPPORT + ================= + Applications can send and receive UTF-8 encoded text data from and to the + system clipboard. By default, clipboard support is disabled and + must be enabled at startup via the following sapp_desc struct + members: + + sapp_desc.enable_clipboard - set to true to enable clipboard support + sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes + + Enabling the clipboard will dynamically allocate a clipboard buffer + for UTF-8 encoded text data of the requested size in bytes, the default + size is 8 KBytes. Strings that don't fit into the clipboard buffer + (including the terminating zero) will be silently clipped, so it's + important that you provide a big enough clipboard size for your + use case. + + To send data to the clipboard, call sapp_set_clipboard_string() with + a pointer to an UTF-8 encoded, null-terminated C-string. + + NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be + called from inside a 'short-lived event handler', and there are a few + other HTML5-specific caveats to workaround. You'll basically have to + tinker until it works in all browsers :/ (maybe the situation will + improve when all browsers agree on and implement the new + HTML5 navigator.clipboard API). + + To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED + event in your event handler function, and then call sapp_get_clipboard_string() + to obtain the pasted UTF-8 encoded text. + + NOTE that behaviour of sapp_get_clipboard_string() is slightly different + depending on platform: + + - on the HTML5 platform, the internal clipboard buffer will only be updated + right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent, + and sapp_get_clipboard_string() will simply return the current content + of the clipboard buffer + - on 'native' platforms, the call to sapp_get_clipboard_string() will + update the internal clipboard buffer with the most recent data + from the system clipboard + + Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event, + and then call sapp_get_clipboard_string() right in the event handler. + + The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app + as follows: + + - on macOS: when the Cmd+V key is pressed down + - on HTML5: when the browser sends a 'paste' event to the global 'window' object + - on all other platforms: when the Ctrl+V key is pressed down + + DRAG AND DROP SUPPORT + ===================== + PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5 + and on the native desktop platforms (Win32, Linux and macOS) because + of security-related restrictions in the HTML5 drag'n'drop API. The + WASM/HTML5 specifics are described at the end of this documentation + section: + + Like clipboard support, drag'n'drop support must be explicitly enabled + at startup in the sapp_desc struct. + + sapp_desc sokol_main() { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + ... + }; + } + + You can also adjust the maximum number of files that are accepted + in a drop operation, and the maximum path length in bytes if needed: + + sapp_desc sokol_main() { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + .max_dropped_files = 8, // default is 1 + .max_dropped_file_path_length = 8192, // in bytes, default is 2048 + ... + }; + } + + When drag'n'drop is enabled, the event callback will be invoked with an + event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on + the application window. + + After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the + number of dropped files, and their absolute paths by calling separate + functions: + + void on_event(const sapp_event* ev) { + if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) { + + // the mouse position where the drop happened + float x = ev->mouse_x; + float y = ev->mouse_y; + + // get the number of files and their paths like this: + const int num_dropped_files = sapp_get_num_dropped_files(); + for (int i = 0; i < num_dropped_files; i++) { + const char* path = sapp_get_dropped_file_path(i); + ... + } + } + } + + The returned file paths are UTF-8 encoded strings. + + You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path() + anywhere, also outside the event handler callback, but be aware that the + file path strings will be overwritten with the next drop operation. + + In any case, sapp_get_dropped_file_path() will never return a null pointer, + instead an empty string "" will be returned if the drag'n'drop feature + hasn't been enabled, the last drop-operation failed, or the file path index + is out of range. + + Drag'n'drop caveats: + + - if more files are dropped in a single drop-action + than sapp_desc.max_dropped_files, the additional + files will be silently ignored + - if any of the file paths is longer than + sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8 + encoding) the entire drop operation will be silently ignored (this + needs some sort of error feedback in the future) + - no mouse positions are reported while the drag is in + process, this may change in the future + + Drag'n'drop on HTML5/WASM: + + The HTML5 drag'n'drop API doesn't return file paths, but instead + black-box 'file objects' which must be used to load the content + of dropped files. This is the reason why sokol_app.h adds two + HTML5-specific functions to the drag'n'drop API: + + uint32_t sapp_html5_get_dropped_file_size(int index) + Returns the size in bytes of a dropped file. + + void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request) + Asynchronously loads the content of a dropped file into a + provided memory buffer (which must be big enough to hold + the file content) + + To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED + event is received: + + sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){ + .dropped_file_index = 0, + .callback = fetch_cb + .buffer = { + .ptr = buf, + .size = sizeof(buf) + }, + .user_data = ... + }); + + Make sure that the memory pointed to by 'buf' stays valid until the + callback function is called! + + As result of the asynchronous loading operation (no matter if succeeded or + failed) the 'fetch_cb' function will be called: + + void fetch_cb(const sapp_html5_fetch_response* response) { + // IMPORTANT: check if the loading operation actually succeeded: + if (response->succeeded) { + // the size of the loaded file: + const size_t num_bytes = response->data.size; + // and the pointer to the data (same as 'buf' in the fetch-call): + const void* ptr = response->data.ptr; + } + else { + // on error check the error code: + switch (response->error_code) { + case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL: + ... + break; + case SAPP_HTML5_FETCH_ERROR_OTHER: + ... + break; + } + } + } + + Check the droptest-sapp example for a real-world example which works + both on native platforms and the web: + + https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c + + HIGH-DPI RENDERING + ================== + You can set the sapp_desc.high_dpi flag during initialization to request + a full-resolution framebuffer on HighDPI displays. The default behaviour + is sapp_desc.high_dpi=false, this means that the application will + render to a lower-resolution framebuffer on HighDPI displays and the + rendered content will be upscaled by the window system composer. + + In a HighDPI scenario, you still request the same window size during + sokol_main(), but the framebuffer sizes returned by sapp_width() + and sapp_height() will be scaled up according to the DPI scaling + ratio. + + Note that on some platforms the DPI scaling factor may change at any + time (for instance when a window is moved from a high-dpi display + to a low-dpi display). + + To query the current DPI scaling factor, call the function: + + float sapp_dpi_scale(void); + + For instance on a Retina Mac, returning the following sapp_desc + struct from sokol_main(): + + sapp_desc sokol_main() { + return (sapp_desc) { + .width = 640, + .height = 480, + .high_dpi = true, + ... + }; + } + + ...the functions the functions sapp_width(), sapp_height() + and sapp_dpi_scale() will return the following values: + + sapp_width: 1280 + sapp_height: 960 + sapp_dpi_scale: 2.0 + + If the high_dpi flag is false, or you're not running on a Retina display, + the values would be: + + sapp_width: 640 + sapp_height: 480 + sapp_dpi_scale: 1.0 + + If the window is moved from the Retina display to a low-dpi external display, + the values would change as follows: + + sapp_width: 1280 => 640 + sapp_height: 960 => 480 + sapp_dpi_scale: 2.0 => 1.0 + + Currently there is no event associated with a DPI change, but an + SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the + framebuffer size changing. + + Per-monitor DPI is currently supported on macOS and Windows. + + APPLICATION QUIT + ================ + Without special quit handling, a sokol_app.h application will quit + 'gracefully' when the user clicks the window close-button unless a + platform's application model prevents this (e.g. on web or mobile). + 'Graceful exit' means that the application-provided cleanup callback will + be called before the application quits. + + On native desktop platforms sokol_app.h provides more control over the + application-quit-process. It's possible to initiate a 'programmatic quit' + from the application code, and a quit initiated by the application user can + be intercepted (for instance to show a custom dialog box). + + This 'programmatic quit protocol' is implemented through 3 functions + and 1 event: + + - sapp_quit(): This function simply quits the application without + giving the user a chance to intervene. Usually this might + be called when the user clicks the 'Ok' button in a 'Really Quit?' + dialog box + - sapp_request_quit(): Calling sapp_request_quit() will send the + event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler + callback, giving the user code a chance to intervene and cancel the + pending quit process (for instance to show a 'Really Quit?' dialog + box). If the event handler callback does nothing, the application + will be quit as usual. To prevent this, call the function + sapp_cancel_quit() from inside the event handler. + - sapp_cancel_quit(): Cancels a pending quit request, either initiated + by the user clicking the window close button, or programmatically + by calling sapp_request_quit(). The only place where calling this + function makes sense is from inside the event handler callback when + the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received. + - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user + clicks the window's close button or application code calls the + sapp_request_quit() function. The event handler callback code can handle + this event by calling sapp_cancel_quit() to cancel the quit. + If the event is ignored, the application will quit as usual. + + On the web platform, the quit behaviour differs from native platforms, + because of web-specific restrictions: + + A `programmatic quit` initiated by calling sapp_quit() or + sapp_request_quit() will work as described above: the cleanup callback is + called, platform-specific cleanup is performed (on the web + this means that JS event handlers are unregisters), and then + the request-animation-loop will be exited. However that's all. The + web page itself will continue to exist (e.g. it's not possible to + programmatically close the browser tab). + + On the web it's also not possible to run custom code when the user + closes a brower tab, so it's not possible to prevent this with a + fancy custom dialog box. + + Instead the standard "Leave Site?" dialog box can be activated (or + deactivated) with the following function: + + sapp_html5_ask_leave_site(bool ask); + + The initial state of the associated internal flag can be provided + at startup via sapp_desc.html5_ask_leave_site. + + This feature should only be used sparingly in critical situations - for + instance when the user would loose data - since popping up modal dialog + boxes is considered quite rude in the web world. Note that there's no way + to customize the content of this dialog box or run any code as a result + of the user's decision. Also note that the user must have interacted with + the site before the dialog box will appear. These are all security measures + to prevent fishing. + + The Dear ImGui HighDPI sample contains example code of how to + implement a 'Really Quit?' dialog box with Dear ImGui (native desktop + platforms only), and for showing the hardwired "Leave Site?" dialog box + when running on the web platform: + + https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html + + FULLSCREEN + ========== + If the sapp_desc.fullscreen flag is true, sokol-app will try to create + a fullscreen window on platforms with a 'proper' window system + (mobile devices will always use fullscreen). The implementation details + depend on the target platform, in general sokol-app will use a + 'soft approach' which doesn't interfere too much with the platform's + window system (for instance borderless fullscreen window instead of + a 'real' fullscreen mode). Such details might change over time + as sokol-app is adapted for different needs. + + The most important effect of fullscreen mode to keep in mind is that + the requested canvas width and height will be ignored for the initial + window size, calling sapp_width() and sapp_height() will instead return + the resolution of the fullscreen canvas (however the provided size + might still be used for the non-fullscreen window, in case the user can + switch back from fullscreen- to windowed-mode). + + To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen(). + + To check if the application window is currently in fullscreen mode, + call sapp_is_fullscreen(). + + WINDOW ICON SUPPORT + =================== + Some sokol_app.h backends allow to change the window icon programmatically: + + - on Win32: the small icon in the window's title bar, and the + bigger icon in the task bar + - on Linux: highly dependent on the used window manager, but usually + the window's title bar icon and/or the task bar icon + - on HTML5: the favicon shown in the page's browser tab + + NOTE that it is not possible to set the actual application icon which is + displayed by the operating system on the desktop or 'home screen'. Those + icons must be provided 'traditionally' through operating-system-specific + resources which are associated with the application (sokol_app.h might + later support setting the window icon from platform specific resource data + though). + + There are two ways to set the window icon: + + - at application start in the sokol_main() function by initializing + the sapp_desc.icon nested struct + - or later by calling the function sapp_set_icon() + + As a convenient shortcut, sokol_app.h comes with a builtin default-icon + (a rainbow-colored 'S', which at least looks a bit better than the Windows + default icon for applications), which can be activated like this: + + At startup in sokol_main(): + + sapp_desc sokol_main(...) { + return (sapp_desc){ + ... + icon.sokol_default = true + }; + } + + Or later by calling: + + sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true }); + + NOTE that a completely zero-initialized sapp_icon_desc struct will not + update the window icon in any way. This is an 'escape hatch' so that you + can handle the window icon update yourself (or if you do this already, + sokol_app.h won't get in your way, in this case just leave the + sapp_desc.icon struct zero-initialized). + + Providing your own icon images works exactly like in GLFW (down to the + data format): + + You provide one or more 'candidate images' in different sizes, and the + sokol_app.h platform backends pick the best match for the specific backend + and icon type. + + For each candidate image, you need to provide: + + - the width in pixels + - the height in pixels + - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844 + on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44) + + For instance, if you have 3 candidate images (small, medium, big) of + sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup + like this: + + // the actual pixel data (RGBA8, origin top-left) + const uint32_t small[16][16] = { ... }; + const uint32_t medium[32][32] = { ... }; + const uint32_t big[64][64] = { ... }; + + const sapp_icon_desc icon_desc = { + .images = { + { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) }, + { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) }, + // ...or without the SAPP_RANGE helper macro: + { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } } + } + }; + + An sapp_icon_desc struct initialized like this can then either be applied + at application start in sokol_main: + + sapp_desc sokol_main(...) { + return (sapp_desc){ + ... + icon = icon_desc + }; + } + + ...or later by calling sapp_set_icon(): + + sapp_set_icon(&icon_desc); + + Some window icon caveats: + + - once the window icon has been updated, there's no way to go back to + the platform's default icon, this is because some platforms (Linux + and HTML5) don't switch the icon visual back to the default even if + the custom icon is deleted or removed + - on HTML5, if the sokol_app.h icon doesn't show up in the browser + tab, check that there's no traditional favicon 'link' element + is defined in the page's index.html, sokol_app.h will only + append a new favicon link element, but not delete any manually + defined favicon in the page + + For an example and test of the window icon feature, check out the the + 'icon-sapp' sample on the sokol-samples git repository. + + ONSCREEN KEYBOARD + ================= + On some platforms which don't provide a physical keyboard, sokol-app + can display the platform's integrated onscreen keyboard for text + input. To request that the onscreen keyboard is shown, call + + sapp_show_keyboard(true); + + Likewise, to hide the keyboard call: + + sapp_show_keyboard(false); + + Note that on the web platform, the keyboard can only be shown from + inside an input handler. On such platforms, sapp_show_keyboard() + will only work as expected when it is called from inside the + sokol-app event callback function. When called from other places, + an internal flag will be set, and the onscreen keyboard will be + called at the next 'legal' opportunity (when the next input event + is handled). + + OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY) + ====================================================== + In its default configuration, sokol_app.h "hijacks" the platform's + standard main() function. This was done because different platforms + have different main functions which are not compatible with + C's main() (for instance WinMain on Windows has completely different + arguments). However, this "main hijacking" posed a problem for + usage scenarios like integrating sokol_app.h with other languages than + C or C++, so an alternative SOKOL_NO_ENTRY mode has been added + in which the user code provides the platform's main function: + + - define SOKOL_NO_ENTRY before including the sokol_app.h implementation + - do *not* provide a sokol_main() function + - instead provide the standard main() function of the platform + - from the main function, call the function ```sapp_run()``` which + takes a pointer to an ```sapp_desc``` structure. + - ```sapp_run()``` takes over control and calls the provided init-, frame-, + shutdown- and event-callbacks just like in the default model, it + will only return when the application quits (or not at all on some + platforms, like emscripten) + + NOTE: SOKOL_NO_ENTRY is currently not supported on Android. + + WINDOWS CONSOLE OUTPUT + ====================== + On Windows, regular windowed applications don't show any stdout/stderr text + output, which can be a bit of a hassle for printf() debugging or generally + logging text to the console. Also, console output by default uses a local + codepage setting and thus international UTF-8 encoded text is printed + as garbage. + + To help with these issues, sokol_app.h can be configured at startup + via the following Windows-specific sapp_desc flags: + + sapp_desc.win32_console_utf8 (default: false) + When set to true, the output console codepage will be switched + to UTF-8 (and restored to the original codepage on exit) + + sapp_desc.win32_console_attach (default: false) + When set to true, stdout and stderr will be attached to the + console of the parent process (if the parent process actually + has a console). This means that if the application was started + in a command line window, stdout and stderr output will be printed + to the terminal, just like a regular command line program. But if + the application is started via double-click, it will behave like + a regular UI application, and stdout/stderr will not be visible. + + sapp_desc.win32_console_create (default: false) + When set to true, a new console window will be created and + stdout/stderr will be redirected to that console window. It + doesn't matter if the application is started from the command + line or via double-click. + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc){ + // ... + .allocator = { + .alloc = my_alloc, + .free = my_free, + .user_data = ..., + } + }; + } + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_app.h + itself though, not any allocations in OS libraries. + + + LOG FUNCTION OVERRIDE + ===================== + You can override the log function at initialization time like this: + + void my_log(const char* message, void* user_data) { + printf("sapp says: \s\n", message); + } + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc){ + // ... + .logger = { + .log_cb = my_log, + .user_data = ..., + } + }; + } + + If no overrides are provided, puts will be used on most platforms. + On Android, __android_log_write will be used instead. + + + TEMP NOTE DUMP + ============== + - onscreen keyboard support on Android requires Java :(, should we even bother? + - sapp_desc needs a bool whether to initialize depth-stencil surface + - GL context initialization needs more control (at least what GL version to initialize) + - application icon + - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy + at the latest but should do it earlier, in onStop, as an app is "killable" after onStop + on Android Honeycomb and later (it can't be done at the moment as the app may be started + again after onStop and the sokol lifecycle does not yet handle context teardown/bringup) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

These zero-init values + will be replaced with their concrete values in the returned desc + struct. + + + ON INITIALIZATION: + ================== + When calling sg_setup(), a pointer to an sg_desc struct must be provided + which contains initialization options. These options provide two types + of information to sokol-gfx: + + (1) upper bounds and limits needed to allocate various internal + data structures: + - the max number of resources of each type that can + be alive at the same time, this is used for allocating + internal pools + - the max overall size of uniform data that can be + updated per frame, including a worst-case alignment + per uniform update (this worst-case alignment is 256 bytes) + - the max size of all dynamic resource updates (sg_update_buffer, + sg_append_buffer and sg_update_image) per frame + - the max number of entries in the texture sampler cache + (how many unique texture sampler can exist at the same time) + Not all of those limit values are used by all backends, but it is + good practice to provide them none-the-less. + + (2) 3D-API "context information" (sometimes also called "bindings"): + sokol_gfx.h doesn't create or initialize 3D API objects which are + closely related to the presentation layer (this includes the "rendering + device", the swapchain, and any objects which depend on the + swapchain). These API objects (or callback functions to obtain + them, if those objects might change between frames), must + be provided in a nested sg_context_desc struct inside the + sg_desc struct. If sokol_gfx.h is used together with + sokol_app.h, have a look at the sokol_glue.h header which provides + a convenience function to get a sg_context_desc struct filled out + with context information provided by sokol_app.h + + See the documention block of the sg_desc struct below for more information. + + + UNIFORM DATA LAYOUT: + ==================== + NOTE: if you use the sokol-shdc shader compiler tool, you don't need to worry + about the following details. + + The data that's passed into the sg_apply_uniforms() function must adhere to + specific layout rules so that the GPU shader finds the uniform block + items at the right offset. + + For the D3D11 and Metal backends, sokol-gfx only cares about the size of uniform + blocks, but not about the internal layout. The data will just be copied into + a uniform/constant buffer in a single operation and it's up you to arrange the + CPU-side layout so that it matches the GPU side layout. This also means that with + the D3D11 and Metal backends you are not limited to a 'cross-platform' subset + of uniform variable types. + + If you ever only use one of the D3D11, Metal *or* WebGPU backend, you can stop reading here. + + For the GL backends, the internal layout of uniform blocks matters though, + and you are limited to a small number of uniform variable types. This is + because sokol-gfx must be able to locate the uniform block members in order + to upload them to the GPU with glUniformXXX() calls. + + To describe the uniform block layout to sokol-gfx, the following information + must be passed to the sg_make_shader() call in the sg_shader_desc struct: + + - a hint about the used packing rule (either SG_UNIFORMLAYOUT_NATIVE or + SG_UNIFORMLAYOUT_STD140) + - a list of the uniform block members types in the correct order they + appear on the CPU side + + For example if the GLSL shader has the following uniform declarations: + + uniform mat4 mvp; + uniform vec2 offset0; + uniform vec2 offset1; + uniform vec2 offset2; + + ...and on the CPU side, there's a similar C struct: + + typedef struct { + float mvp[16]; + float offset0[2]; + float offset1[2]; + float offset2[2]; + } params_t; + + ...the uniform block description in the sg_shader_desc must look like this: + + sg_shader_desc desc = { + .vs.uniform_blocks[0] = { + .size = sizeof(params_t), + .layout = SG_UNIFORMLAYOUT_NATIVE, // this is the default and can be omitted + .uniforms = { + // order must be the same as in 'params_t': + [0] = { .name = "mvp", .type = SG_UNIFORMTYPE_MAT4 }, + [1] = { .name = "offset0", .type = SG_UNIFORMTYPE_VEC2 }, + [2] = { .name = "offset1", .type = SG_UNIFORMTYPE_VEC2 }, + [3] = { .name = "offset2", .type = SG_UNIFORMTYPE_VEC2 }, + } + } + }; + + With this information sokol-gfx can now compute the correct offsets of the data items + within the uniform block struct. + + The SG_UNIFORMLAYOUT_NATIVE packing rule works fine if only the GL backends are used, + but for proper D3D11/Metal/GL a subset of the std140 layout must be used which is + described in the next section: + + + CROSS-BACKEND COMMON UNIFORM DATA LAYOUT + ======================================== + For cross-platform / cross-3D-backend code it is important that the same uniform block + layout on the CPU side can be used for all sokol-gfx backends. To achieve this, + a common subset of the std140 layout must be used: + + - The uniform block layout hint in sg_shader_desc must be explicitely set to + SG_UNIFORMLAYOUT_STD140. + - Only the following GLSL uniform types can be used (with their associated sokol-gfx enums): + - float => SG_UNIFORMTYPE_FLOAT + - vec2 => SG_UNIFORMTYPE_FLOAT2 + - vec3 => SG_UNIFORMTYPE_FLOAT3 + - vec4 => SG_UNIFORMTYPE_FLOAT4 + - int => SG_UNIFORMTYPE_INT + - ivec2 => SG_UNIFORMTYPE_INT2 + - ivec3 => SG_UNIFORMTYPE_INT3 + - ivec4 => SG_UNIFORMTYPE_INT4 + - mat4 => SG_UNIFORMTYPE_MAT4 + - Alignment for those types must be as follows (in bytes): + - float => 4 + - vec2 => 8 + - vec3 => 16 + - vec4 => 16 + - int => 4 + - ivec2 => 8 + - ivec3 => 16 + - ivec4 => 16 + - mat4 => 16 + - Arrays are only allowed for the following types: vec4, int4, mat4. + + Note that the HLSL cbuffer layout rules are slightly different from the + std140 layout rules, this means that the cbuffer declarations in HLSL code + must be tweaked so that the layout is compatible with std140. + + The by far easiest way to tacke the common uniform block layout problem is + to use the sokol-shdc shader cross-compiler tool! + + + BACKEND-SPECIFIC TOPICS: + ======================== + --- The GL backends need to know about the internal structure of uniform + blocks, and the texture sampler-name and -type. The uniform layout details + are described in the UNIFORM DATA LAYOUT section above. + + // uniform block structure and texture image definition in sg_shader_desc: + sg_shader_desc desc = { + // uniform block description (size and internal structure) + .vs.uniform_blocks[0] = { + ... + }, + // one texture on the fragment-shader-stage, GLES2/WebGL needs name and image type + .fs.images[0] = { .name="tex", .type=SG_IMAGETYPE_ARRAY } + ... + }; + + --- the Metal and D3D11 backends only need to know the size of uniform blocks, + not their internal member structure, and they only need to know + the type of a texture sampler, not its name: + + sg_shader_desc desc = { + .vs.uniform_blocks[0].size = sizeof(params_t), + .fs.images[0].type = SG_IMAGETYPE_ARRAY, + ... + }; + + --- when creating a shader object, GLES2/WebGL need to know the vertex + attribute names as used in the vertex shader: + + sg_shader_desc desc = { + .attrs = { + [0] = { .name="position" }, + [1] = { .name="color1" } + } + }; + + The vertex attribute names provided when creating a shader will be + used later in sg_create_pipeline() for matching the vertex layout + to vertex shader inputs. + + --- on D3D11 you need to provide a semantic name and semantic index in the + shader description struct instead (see the D3D11 documentation on + D3D11_INPUT_ELEMENT_DESC for details): + + sg_shader_desc desc = { + .attrs = { + [0] = { .sem_name="POSITION", .sem_index=0 } + [1] = { .sem_name="COLOR", .sem_index=1 } + } + }; + + The provided semantic information will be used later in sg_create_pipeline() + to match the vertex layout to vertex shader inputs. + + --- on D3D11, and when passing HLSL source code (instead of byte code) to shader + creation, you can optionally define the shader model targets on the vertex + stage: + + sg_shader_Desc desc = { + .vs = { + ... + .d3d11_target = "vs_5_0" + }, + .fs = { + ... + .d3d11_target = "ps_5_0" + } + }; + + The default targets are "ps_4_0" and "fs_4_0". Note that those target names + are only used when compiling shaders from source. They are ignored when + creating a shader from bytecode. + + --- on Metal, GL 3.3 or GLES3/WebGL2, you don't need to provide an attribute + name or semantic name, since vertex attributes can be bound by their slot index + (this is mandatory in Metal, and optional in GL): + + sg_pipeline_desc desc = { + .layout = { + .attrs = { + [0] = { .format=SG_VERTEXFORMAT_FLOAT3 }, + [1] = { .format=SG_VERTEXFORMAT_FLOAT4 } + } + } + }; + + + WORKING WITH CONTEXTS + ===================== + sokol-gfx allows to switch between different rendering contexts and + associate resource objects with contexts. This is useful to + create GL applications that render into multiple windows. + + A rendering context keeps track of all resources created while + the context is active. When the context is destroyed, all resources + "belonging to the context" are destroyed as well. + + A default context will be created and activated implicitly in + sg_setup(), and destroyed in sg_shutdown(). So for a typical application + which *doesn't* use multiple contexts, nothing changes, and calling + the context functions isn't necessary. + + Three functions have been added to work with contexts: + + --- sg_context sg_setup_context(): + This must be called once after a GL context has been created and + made active. + + --- void sg_activate_context(sg_context ctx) + This must be called after making a different GL context active. + Apart from 3D-API-specific actions, the call to sg_activate_context() + will internally call sg_reset_state_cache(). + + --- void sg_discard_context(sg_context ctx) + This must be called right before a GL context is destroyed and + will destroy all resources associated with the context (that + have been created while the context was active) The GL context must be + active at the time sg_discard_context(sg_context ctx) is called. + + Also note that resources (buffers, images, shaders and pipelines) must + only be used or destroyed while the same GL context is active that + was also active while the resource was created (an exception is + resource sharing on GL, such resources can be used while + another context is active, but must still be destroyed under + the same context that was active during creation). + + For more information, check out the multiwindow-glfw sample: + + https://github.com/floooh/sokol-samples/blob/master/glfw/multiwindow-glfw.c + + + TRACE HOOKS: + ============ + sokol_gfx.h optionally allows to install "trace hook" callbacks for + each public API functions. When a public API function is called, and + a trace hook callback has been installed for this function, the + callback will be invoked with the parameters and result of the function. + This is useful for things like debugging- and profiling-tools, or + keeping track of resource creation and destruction. + + To use the trace hook feature: + + --- Define SOKOL_TRACE_HOOKS before including the implementation. + + --- Setup an sg_trace_hooks structure with your callback function + pointers (keep all function pointers you're not interested + in zero-initialized), optionally set the user_data member + in the sg_trace_hooks struct. + + --- Install the trace hooks by calling sg_install_trace_hooks(), + the return value of this function is another sg_trace_hooks + struct which contains the previously set of trace hooks. + You should keep this struct around, and call those previous + functions pointers from your own trace callbacks for proper + chaining. + + As an example of how trace hooks are used, have a look at the + imgui/sokol_gfx_imgui.h header which implements a realtime + debugging UI for sokol_gfx.h on top of Dear ImGui. + + + A NOTE ON PORTABLE PACKED VERTEX FORMATS: + ========================================= + There are two things to consider when using packed + vertex formats like UBYTE4, SHORT2, etc which need to work + across all backends: + + - D3D11 can only convert *normalized* vertex formats to + floating point during vertex fetch, normalized formats + have a trailing 'N', and are "normalized" to a range + -1.0..+1.0 (for the signed formats) or 0.0..1.0 (for the + unsigned formats): + + - SG_VERTEXFORMAT_BYTE4N + - SG_VERTEXFORMAT_UBYTE4N + - SG_VERTEXFORMAT_SHORT2N + - SG_VERTEXFORMAT_USHORT2N + - SG_VERTEXFORMAT_SHORT4N + - SG_VERTEXFORMAT_USHORT4N + + D3D11 will not convert *non-normalized* vertex formats to floating point + vertex shader inputs, those can only be uses with the *ivecn* vertex shader + input types when D3D11 is used as backend (GL and Metal can use both formats) + + - SG_VERTEXFORMAT_BYTE4, + - SG_VERTEXFORMAT_UBYTE4 + - SG_VERTEXFORMAT_SHORT2 + - SG_VERTEXFORMAT_SHORT4 + + - WebGL/GLES2 cannot use integer vertex shader inputs (int or ivecn) + + - SG_VERTEXFORMAT_UINT10_N2 is not supported on WebGL/GLES2 + + So for a vertex input layout which works on all platforms, only use the following + vertex formats, and if needed "expand" the normalized vertex shader + inputs in the vertex shader by multiplying with 127.0, 255.0, 32767.0 or + 65535.0: + + - SG_VERTEXFORMAT_FLOAT, + - SG_VERTEXFORMAT_FLOAT2, + - SG_VERTEXFORMAT_FLOAT3, + - SG_VERTEXFORMAT_FLOAT4, + - SG_VERTEXFORMAT_BYTE4N, + - SG_VERTEXFORMAT_UBYTE4N, + - SG_VERTEXFORMAT_SHORT2N, + - SG_VERTEXFORMAT_USHORT2N + - SG_VERTEXFORMAT_SHORT4N, + - SG_VERTEXFORMAT_USHORT4N + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sg_setup(&(sg_desc){ + // ... + .allocator = { + .alloc = my_alloc, + .free = my_free, + .user_data = ..., + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_gfx.h + itself though, not any allocations in OS libraries. + + + LOG FUNCTION OVERRIDE + ===================== + You can override the log function at initialization time like this: + + void my_log(const char* message, void* user_data) { + printf("sg says: \s\n", message); + } + + ... + sg_setup(&(sg_desc){ + // ... + .logger = { + .log_cb = my_log, + .user_data = ..., + } + }); + ... + + If no overrides are provided, puts will be used on most platforms. + On Android, __android_log_write will be used instead. + + + COMMIT LISTENERS + ================ + It's possible to hook callback functions into sokol-gfx which are called from + inside sg_commit() in unspecified order. This is mainly useful for libraries + that build on top of sokol_gfx.h to be notified about the end/start of a frame. + + To add a commit listener, call: + + static void my_commit_listener(void* user_data) { + ... + } + + bool success = sg_add_commit_listener((sg_commit_listener){ + .func = my_commit_listener, + .user_data = ..., + }); + + The function returns false if the internal array of commit listeners is full, + or the same commit listener had already been added. + + If the function returns true, my_commit_listener() will be called each frame + from inside sg_commit(). + + By default, 1024 distinct commit listeners can be added, but this number + can be tweaked in the sg_setup() call: + + sg_setup(&(sg_desc){ + .max_commit_listeners = 2048, + }); + + An sg_commit_listener item is equal to another if both the function + pointer and user_data field are equal. + + To remove a commit listener: + + bool success = sg_remove_commit_listener((sg_commit_listener){ + .func = my_commit_listener, + .user_data = ..., + }); + + ...where the .func and .user_data field are equal to a previous + sg_add_commit_listener() call. The function returns true if the commit + listener item was found and removed, and false otherwise. + + + RESOURCE CREATION AND DESTRUCTION IN DETAIL + =========================================== + The 'vanilla' way to create resource objects is with the 'make functions': + + sg_buffer sg_make_buffer(const sg_buffer_desc* desc) + sg_image sg_make_image(const sg_image_desc* desc) + sg_shader sg_make_shader(const sg_shader_desc* desc) + sg_pipeline sg_make_pipeline(const sg_pipeline_desc* desc) + sg_pass sg_make_pass(const sg_pass_desc* desc) + + This will result in one of three cases: + + 1. The returned handle is invalid. This happens when there are no more + free slots in the resource pool for this resource type. An invalid + handle is associated with the INVALID resource state, for instance: + + sg_buffer buf = sg_make_buffer(...) + if (sg_query_buffer_state(buf) == SG_RESOURCESTATE_INVALID) { + // buffer pool is exhausted + } + + 2. The returned handle is valid, but creating the underlying resource + has failed for some reason. This results in a resource object in the + FAILED state. The reason *why* resource creation has failed differ + by resource type. Look for log messages with more details.

This - function is called very early, usually at the start of the - platform's entry function (e.g. main or WinMain). You should do as - little as possible here, since the rest of your code might be called - from another thread (this depends on the platform): - - sapp_desc sokol_main(int argc, char* argv[]) { - return (sapp_desc) { - .width = 640, - .height = 480, - .init_cb = my_init_func, - .frame_cb = my_frame_func, - .cleanup_cb = my_cleanup_func, - .event_cb = my_event_func, - ... - }; - } - - There are many more setup parameters, but these are the most important. - For a complete list search for the sapp_desc structure declaration - below. - - DO NOT call any sokol-app function from inside sokol_main(), since - sokol-app will not be initialized at this point. - - The .width and .height parameters are the preferred size of the 3D - rendering canvas. The actual size may differ from this depending on - platform and other circumstances. Also the canvas size may change at - any time (for instance when the user resizes the application window, - or rotates the mobile device). You can just keep .width and .height - zero-initialized to open a default-sized window (what "default-size" - exactly means is platform-specific, but usually it's a size that covers - most of, but not all, of the display). - - All provided function callbacks will be called from the same thread, - but this may be different from the thread where sokol_main() was called. - - .init_cb (void (*)(void)) - This function is called once after the application window, - 3D rendering context and swap chain have been created. The - function takes no arguments and has no return value. - .frame_cb (void (*)(void)) - This is the per-frame callback, which is usually called 60 - times per second. This is where your application would update - most of its state and perform all rendering. - .cleanup_cb (void (*)(void)) - The cleanup callback is called once right before the application - quits. - .event_cb (void (*)(const sapp_event* event)) - The event callback is mainly for input handling, but is also - used to communicate other types of events to the application. Keep the - event_cb struct member zero-initialized if your application doesn't require - event handling. - .fail_cb (void (*)(const char* msg)) - The fail callback is called when a fatal error is encountered - during start which doesn't allow the program to continue. - Providing a callback here gives you a chance to show an error message - to the user. The default behaviour is SOKOL_LOG(msg) - - As you can see, those 'standard callbacks' don't have a user_data - argument, so any data that needs to be preserved between callbacks - must live in global variables. If keeping state in global variables - is not an option, there's an alternative set of callbacks with - an additional user_data pointer argument: - - .user_data (void*) - The user-data argument for the callbacks below - .init_userdata_cb (void (*)(void* user_data)) - .frame_userdata_cb (void (*)(void* user_data)) - .cleanup_userdata_cb (void (*)(void* user_data)) - .event_userdata_cb (void(*)(const sapp_event* event, void* user_data)) - .fail_userdata_cb (void(*)(const char* msg, void* user_data)) - These are the user-data versions of the callback functions. You - can mix those with the standard callbacks that don't have the - user_data argument. - - The function sapp_userdata() can be used to query the user_data - pointer provided in the sapp_desc struct. - - You can also call sapp_query_desc() to get a copy of the - original sapp_desc structure. - - NOTE that there's also an alternative compile mode where sokol_app.h - doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY. - - --- Implement the initialization callback function (init_cb), this is called - once after the rendering surface, 3D API and swap chain have been - initialized by sokol_app. All sokol-app functions can be called - from inside the initialization callback, the most useful functions - at this point are: - - int sapp_width(void) - int sapp_height(void) - Returns the current width and height of the default framebuffer in pixels, - this may change from one frame to the next, and it may be different - from the initial size provided in the sapp_desc struct. - - float sapp_widthf(void) - float sapp_heightf(void) - These are alternatives to sapp_width() and sapp_height() which return - the default framebuffer size as float values instead of integer. This - may help to prevent casting back and forth between int and float - in more strongly typed languages than C and C++. - - double sapp_frame_duration(void) - Returns the frame duration in seconds averaged over a number of - frames to smooth out any jittering spikes. - - int sapp_color_format(void) - int sapp_depth_format(void) - The color and depth-stencil pixelformats of the default framebuffer, - as integer values which are compatible with sokol-gfx's - sg_pixel_format enum (so that they can be plugged directly in places - where sg_pixel_format is expected). Possible values are: - - 23 == SG_PIXELFORMAT_RGBA8 - 27 == SG_PIXELFORMAT_BGRA8 - 41 == SG_PIXELFORMAT_DEPTH - 42 == SG_PIXELFORMAT_DEPTH_STENCIL - - int sapp_sample_count(void) - Return the MSAA sample count of the default framebuffer. - - bool sapp_gles2(void) - Returns true if a GLES2 or WebGL context has been created. This - is useful when a GLES3/WebGL2 context was requested but is not - available so that sokol_app.h had to fallback to GLES2/WebGL. - - const void* sapp_metal_get_device(void) - const void* sapp_metal_get_renderpass_descriptor(void) - const void* sapp_metal_get_drawable(void) - If the Metal backend has been selected, these functions return pointers - to various Metal API objects required for rendering, otherwise - they return a null pointer. These void pointers are actually - Objective-C ids converted with a (ARC) __bridge cast so that - the ids can be tunnel through C code. Also note that the returned - pointers to the renderpass-descriptor and drawable may change from one - frame to the next, only the Metal device object is guaranteed to - stay the same. - - const void* sapp_macos_get_window(void) - On macOS, get the NSWindow object pointer, otherwise a null pointer. - Before being used as Objective-C object, the void* must be converted - back with a (ARC) __bridge cast. - - const void* sapp_ios_get_window(void) - On iOS, get the UIWindow object pointer, otherwise a null pointer. - Before being used as Objective-C object, the void* must be converted - back with a (ARC) __bridge cast. - - const void* sapp_win32_get_hwnd(void) - On Windows, get the window's HWND, otherwise a null pointer. The - HWND has been cast to a void pointer in order to be tunneled - through code which doesn't include Windows.h. - - const void* sapp_d3d11_get_device(void) - const void* sapp_d3d11_get_device_context(void) - const void* sapp_d3d11_get_render_target_view(void) - const void* sapp_d3d11_get_depth_stencil_view(void) - Similar to the sapp_metal_* functions, the sapp_d3d11_* functions - return pointers to D3D11 API objects required for rendering, - only if the D3D11 backend has been selected. Otherwise they - return a null pointer. Note that the returned pointers to the - render-target-view and depth-stencil-view may change from one - frame to the next! - - const void* sapp_wgpu_get_device(void) - const void* sapp_wgpu_get_render_view(void) - const void* sapp_wgpu_get_resolve_view(void) - const void* sapp_wgpu_get_depth_stencil_view(void) - These are the WebGPU-specific functions to get the WebGPU - objects and values required for rendering. If sokol_app.h - is not compiled with SOKOL_WGPU, these functions return null. - - const void* sapp_android_get_native_activity(void); - On Android, get the native activity ANativeActivity pointer, otherwise - a null pointer. - - --- Implement the frame-callback function, this function will be called - on the same thread as the init callback, but might be on a different - thread than the sokol_main() function. Note that the size of - the rendering framebuffer might have changed since the frame callback - was called last. Call the functions sapp_width() and sapp_height() - each frame to get the current size. - - --- Optionally implement the event-callback to handle input events. - sokol-app provides the following type of input events: - - a 'virtual key' was pressed down or released - - a single text character was entered (provided as UTF-32 code point) - - a mouse button was pressed down or released (left, right, middle) - - mouse-wheel or 2D scrolling events - - the mouse was moved - - the mouse has entered or left the application window boundaries - - low-level, portable multi-touch events (began, moved, ended, cancelled) - - the application window was resized, iconified or restored - - the application was suspended or restored (on mobile platforms) - - the user or application code has asked to quit the application - - a string was pasted to the system clipboard - - one or more files have been dropped onto the application window - - To explicitly 'consume' an event and prevent that the event is - forwarded for further handling to the operating system, call - sapp_consume_event() from inside the event handler (NOTE that - this behaviour is currently only implemented for some HTML5 - events, support for other platforms and event types will - be added as needed, please open a github ticket and/or provide - a PR if needed). - - NOTE: Do *not* call any 3D API rendering functions in the event - callback function, since the 3D API context may not be active when the - event callback is called (it may work on some platforms and 3D APIs, - but not others, and the exact behaviour may change between - sokol-app versions). - - --- Implement the cleanup-callback function, this is called once - after the user quits the application (see the section - "APPLICATION QUIT" for detailed information on quitting - behaviour, and how to intercept a pending quit - for instance to show a - "Really Quit?" dialog box). Note that the cleanup-callback isn't - guaranteed to be called on the web and mobile platforms. - - MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE) - ================================================ - In normal mouse mode, no mouse movement events are reported when the - mouse leaves the windows client area or hits the screen border (whether - it's one or the other depends on the platform), and the mouse move events - (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in - framebuffer pixels in the sapp_event items mouse_x and mouse_y, and - relative movement in framebuffer pixels in the sapp_event items mouse_dx - and mouse_dy. - - To get continuous mouse movement (also when the mouse leaves the window - client area or hits the screen border), activate mouse-lock mode - by calling: - - sapp_lock_mouse(true) - - When mouse lock is activated, the mouse pointer is hidden, the - reported absolute mouse position (sapp_event.mouse_x/y) appears - frozen, and the relative mouse movement in sapp_event.mouse_dx/dy - no longer has a direct relation to framebuffer pixels but instead - uses "raw mouse input" (what "raw mouse input" exactly means also - differs by platform). - - To deactivate mouse lock and return to normal mouse mode, call - - sapp_lock_mouse(false) - - And finally, to check if mouse lock is currently active, call - - if (sapp_mouse_locked()) { ... } - - On native platforms, the sapp_lock_mouse() and sapp_mouse_locked() - functions work as expected (mouse lock is activated or deactivated - immediately when sapp_lock_mouse() is called, and sapp_mouse_locked() - also immediately returns the new state after sapp_lock_mouse() - is called. - - On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave - differently, as dictated by the limitations of the HTML5 Pointer Lock API: - - - sapp_lock_mouse(true) can be called at any time, but it will - only take effect in a 'short-lived input event handler of a specific - type', meaning when one of the following events happens: - - SAPP_EVENTTYPE_MOUSE_DOWN - - SAPP_EVENTTYPE_MOUSE_UP - - SAPP_EVENTTYPE_MOUSE_SCROLL - - SAPP_EVENTTYPE_KEY_UP - - SAPP_EVENTTYPE_KEY_DOWN - - The mouse lock/unlock action on the web platform is asynchronous, - this means that sapp_mouse_locked() won't immediately return - the new status after calling sapp_lock_mouse(), instead the - reported status will only change when the pointer lock has actually - been activated or deactivated in the browser. - - On the web, mouse lock can be deactivated by the user at any time - by pressing the Esc key. When this happens, sokol_app.h behaves - the same as if sapp_lock_mouse(false) is called. - - For things like camera manipulation it's most straightforward to lock - and unlock the mouse right from the sokol_app.h event handler, for - instance the following code enters and leaves mouse lock when the - left mouse button is pressed and released, and then uses the relative - movement information to manipulate a camera (taken from the - cgltf-sapp.c sample in the sokol-samples repository - at https://github.com/floooh/sokol-samples): - - static void input(const sapp_event* ev) { - switch (ev->type) { - case SAPP_EVENTTYPE_MOUSE_DOWN: - if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { - sapp_lock_mouse(true); - } - break; - - case SAPP_EVENTTYPE_MOUSE_UP: - if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { - sapp_lock_mouse(false); - } - break; - - case SAPP_EVENTTYPE_MOUSE_MOVE: - if (sapp_mouse_locked()) { - cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f); - } - break; - - default: - break; - } - } - - CLIPBOARD SUPPORT - ================= - Applications can send and receive UTF-8 encoded text data from and to the - system clipboard. By default, clipboard support is disabled and - must be enabled at startup via the following sapp_desc struct - members: - - sapp_desc.enable_clipboard - set to true to enable clipboard support - sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes - - Enabling the clipboard will dynamically allocate a clipboard buffer - for UTF-8 encoded text data of the requested size in bytes, the default - size is 8 KBytes. Strings that don't fit into the clipboard buffer - (including the terminating zero) will be silently clipped, so it's - important that you provide a big enough clipboard size for your - use case. - - To send data to the clipboard, call sapp_set_clipboard_string() with - a pointer to an UTF-8 encoded, null-terminated C-string. - - NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be - called from inside a 'short-lived event handler', and there are a few - other HTML5-specific caveats to workaround. You'll basically have to - tinker until it works in all browsers :/ (maybe the situation will - improve when all browsers agree on and implement the new - HTML5 navigator.clipboard API). - - To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED - event in your event handler function, and then call sapp_get_clipboard_string() - to obtain the pasted UTF-8 encoded text. - - NOTE that behaviour of sapp_get_clipboard_string() is slightly different - depending on platform: - - - on the HTML5 platform, the internal clipboard buffer will only be updated - right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent, - and sapp_get_clipboard_string() will simply return the current content - of the clipboard buffer - - on 'native' platforms, the call to sapp_get_clipboard_string() will - update the internal clipboard buffer with the most recent data - from the system clipboard - - Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event, - and then call sapp_get_clipboard_string() right in the event handler. - - The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app - as follows: - - - on macOS: when the Cmd+V key is pressed down - - on HTML5: when the browser sends a 'paste' event to the global 'window' object - - on all other platforms: when the Ctrl+V key is pressed down - - DRAG AND DROP SUPPORT - ===================== - PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5 - and on the native desktop platforms (Win32, Linux and macOS) because - of security-related restrictions in the HTML5 drag'n'drop API. The - WASM/HTML5 specifics are described at the end of this documentation - section: - - Like clipboard support, drag'n'drop support must be explicitly enabled - at startup in the sapp_desc struct. - - sapp_desc sokol_main() { - return (sapp_desc) { - .enable_dragndrop = true, // default is false - ... - }; - } - - You can also adjust the maximum number of files that are accepted - in a drop operation, and the maximum path length in bytes if needed: - - sapp_desc sokol_main() { - return (sapp_desc) { - .enable_dragndrop = true, // default is false - .max_dropped_files = 8, // default is 1 - .max_dropped_file_path_length = 8192, // in bytes, default is 2048 - ... - }; - } - - When drag'n'drop is enabled, the event callback will be invoked with an - event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on - the application window. - - After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the - number of dropped files, and their absolute paths by calling separate - functions: - - void on_event(const sapp_event* ev) { - if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) { - - // the mouse position where the drop happened - float x = ev->mouse_x; - float y = ev->mouse_y; - - // get the number of files and their paths like this: - const int num_dropped_files = sapp_get_num_dropped_files(); - for (int i = 0; i < num_dropped_files; i++) { - const char* path = sapp_get_dropped_file_path(i); - ... - } - } - } - - The returned file paths are UTF-8 encoded strings. - - You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path() - anywhere, also outside the event handler callback, but be aware that the - file path strings will be overwritten with the next drop operation. - - In any case, sapp_get_dropped_file_path() will never return a null pointer, - instead an empty string "" will be returned if the drag'n'drop feature - hasn't been enabled, the last drop-operation failed, or the file path index - is out of range. - - Drag'n'drop caveats: - - - if more files are dropped in a single drop-action - than sapp_desc.max_dropped_files, the additional - files will be silently ignored - - if any of the file paths is longer than - sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8 - encoding) the entire drop operation will be silently ignored (this - needs some sort of error feedback in the future) - - no mouse positions are reported while the drag is in - process, this may change in the future - - Drag'n'drop on HTML5/WASM: - - The HTML5 drag'n'drop API doesn't return file paths, but instead - black-box 'file objects' which must be used to load the content - of dropped files. This is the reason why sokol_app.h adds two - HTML5-specific functions to the drag'n'drop API: - - uint32_t sapp_html5_get_dropped_file_size(int index) - Returns the size in bytes of a dropped file. - - void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request) - Asynchronously loads the content of a dropped file into a - provided memory buffer (which must be big enough to hold - the file content) - - To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED - event is received: - - sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){ - .dropped_file_index = 0, - .callback = fetch_cb - .buffer_ptr = buf, - .buffer_size = buf_size, - .user_data = ... - }); - - Make sure that the memory pointed to by 'buf' stays valid until the - callback function is called! - - As result of the asynchronous loading operation (no matter if succeeded or - failed) the 'fetch_cb' function will be called: - - void fetch_cb(const sapp_html5_fetch_response* response) { - // IMPORTANT: check if the loading operation actually succeeded: - if (response->succeeded) { - // the size of the loaded file: - const uint32_t num_bytes = response->fetched_size; - // and the pointer to the data (same as 'buf' in the fetch-call): - const void* ptr = response->buffer_ptr; - } - else { - // on error check the error code: - switch (response->error_code) { - case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL: - ... - break; - case SAPP_HTML5_FETCH_ERROR_OTHER: - ... - break; - } - } - } - - Check the droptest-sapp example for a real-world example which works - both on native platforms and the web: - - https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c - - HIGH-DPI RENDERING - ================== - You can set the sapp_desc.high_dpi flag during initialization to request - a full-resolution framebuffer on HighDPI displays. The default behaviour - is sapp_desc.high_dpi=false, this means that the application will - render to a lower-resolution framebuffer on HighDPI displays and the - rendered content will be upscaled by the window system composer. - - In a HighDPI scenario, you still request the same window size during - sokol_main(), but the framebuffer sizes returned by sapp_width() - and sapp_height() will be scaled up according to the DPI scaling - ratio. - - Note that on some platforms the DPI scaling factor may change at any - time (for instance when a window is moved from a high-dpi display - to a low-dpi display). - - To query the current DPI scaling factor, call the function: - - float sapp_dpi_scale(void); - - For instance on a Retina Mac, returning the following sapp_desc - struct from sokol_main(): - - sapp_desc sokol_main() { - return (sapp_desc) { - .width = 640, - .height = 480, - .high_dpi = true, - ... - }; - } - - ...the functions the functions sapp_width(), sapp_height() - and sapp_dpi_scale() will return the following values: - - sapp_width: 1280 - sapp_height: 960 - sapp_dpi_scale: 2.0 - - If the high_dpi flag is false, or you're not running on a Retina display, - the values would be: - - sapp_width: 640 - sapp_height: 480 - sapp_dpi_scale: 1.0 - - If the window is moved from the Retina display to a low-dpi external display, - the values would change as follows: - - sapp_width: 1280 => 640 - sapp_height: 960 => 480 - sapp_dpi_scale: 2.0 => 1.0 - - Currently there is no event associated with a DPI change, but an - SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the - framebuffer size changing. - - Per-monitor DPI is currently supported on macOS and Windows. - - APPLICATION QUIT - ================ - Without special quit handling, a sokol_app.h application will quit - 'gracefully' when the user clicks the window close-button unless a - platform's application model prevents this (e.g. on web or mobile). - 'Graceful exit' means that the application-provided cleanup callback will - be called before the application quits. - - On native desktop platforms sokol_app.h provides more control over the - application-quit-process. It's possible to initiate a 'programmatic quit' - from the application code, and a quit initiated by the application user can - be intercepted (for instance to show a custom dialog box). - - This 'programmatic quit protocol' is implemented through 3 functions - and 1 event: - - - sapp_quit(): This function simply quits the application without - giving the user a chance to intervene. Usually this might - be called when the user clicks the 'Ok' button in a 'Really Quit?' - dialog box - - sapp_request_quit(): Calling sapp_request_quit() will send the - event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler - callback, giving the user code a chance to intervene and cancel the - pending quit process (for instance to show a 'Really Quit?' dialog - box). If the event handler callback does nothing, the application - will be quit as usual. To prevent this, call the function - sapp_cancel_quit() from inside the event handler. - - sapp_cancel_quit(): Cancels a pending quit request, either initiated - by the user clicking the window close button, or programmatically - by calling sapp_request_quit(). The only place where calling this - function makes sense is from inside the event handler callback when - the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received. - - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user - clicks the window's close button or application code calls the - sapp_request_quit() function. The event handler callback code can handle - this event by calling sapp_cancel_quit() to cancel the quit. - If the event is ignored, the application will quit as usual. - - On the web platform, the quit behaviour differs from native platforms, - because of web-specific restrictions: - - A `programmatic quit` initiated by calling sapp_quit() or - sapp_request_quit() will work as described above: the cleanup callback is - called, platform-specific cleanup is performed (on the web - this means that JS event handlers are unregisters), and then - the request-animation-loop will be exited. However that's all. The - web page itself will continue to exist (e.g. it's not possible to - programmatically close the browser tab). - - On the web it's also not possible to run custom code when the user - closes a brower tab, so it's not possible to prevent this with a - fancy custom dialog box. - - Instead the standard "Leave Site?" dialog box can be activated (or - deactivated) with the following function: - - sapp_html5_ask_leave_site(bool ask); - - The initial state of the associated internal flag can be provided - at startup via sapp_desc.html5_ask_leave_site. - - This feature should only be used sparingly in critical situations - for - instance when the user would loose data - since popping up modal dialog - boxes is considered quite rude in the web world. Note that there's no way - to customize the content of this dialog box or run any code as a result - of the user's decision. Also note that the user must have interacted with - the site before the dialog box will appear. These are all security measures - to prevent fishing. - - The Dear ImGui HighDPI sample contains example code of how to - implement a 'Really Quit?' dialog box with Dear ImGui (native desktop - platforms only), and for showing the hardwired "Leave Site?" dialog box - when running on the web platform: - - https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html - - FULLSCREEN - ========== - If the sapp_desc.fullscreen flag is true, sokol-app will try to create - a fullscreen window on platforms with a 'proper' window system - (mobile devices will always use fullscreen). The implementation details - depend on the target platform, in general sokol-app will use a - 'soft approach' which doesn't interfere too much with the platform's - window system (for instance borderless fullscreen window instead of - a 'real' fullscreen mode). Such details might change over time - as sokol-app is adapted for different needs. - - The most important effect of fullscreen mode to keep in mind is that - the requested canvas width and height will be ignored for the initial - window size, calling sapp_width() and sapp_height() will instead return - the resolution of the fullscreen canvas (however the provided size - might still be used for the non-fullscreen window, in case the user can - switch back from fullscreen- to windowed-mode). - - To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen(). - - To check if the application window is currently in fullscreen mode, - call sapp_is_fullscreen(). - - WINDOW ICON SUPPORT - =================== - Some sokol_app.h backends allow to change the window icon programmatically: - - - on Win32: the small icon in the window's title bar, and the - bigger icon in the task bar - - on Linux: highly dependent on the used window manager, but usually - the window's title bar icon and/or the task bar icon - - on HTML5: the favicon shown in the page's browser tab - - NOTE that it is not possible to set the actual application icon which is - displayed by the operating system on the desktop or 'home screen'. Those - icons must be provided 'traditionally' through operating-system-specific - resources which are associated with the application (sokol_app.h might - later support setting the window icon from platform specific resource data - though). - - There are two ways to set the window icon: - - - at application start in the sokol_main() function by initializing - the sapp_desc.icon nested struct - - or later by calling the function sapp_set_icon() - - As a convenient shortcut, sokol_app.h comes with a builtin default-icon - (a rainbow-colored 'S', which at least looks a bit better than the Windows - default icon for applications), which can be activated like this: - - At startup in sokol_main(): - - sapp_desc sokol_main(...) { - return (sapp_desc){ - ... - icon.sokol_default = true - }; - } - - Or later by calling: - - sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true }); - - NOTE that a completely zero-initialized sapp_icon_desc struct will not - update the window icon in any way. This is an 'escape hatch' so that you - can handle the window icon update yourself (or if you do this already, - sokol_app.h won't get in your way, in this case just leave the - sapp_desc.icon struct zero-initialized). - - Providing your own icon images works exactly like in GLFW (down to the - data format): - - You provide one or more 'candidate images' in different sizes, and the - sokol_app.h platform backends pick the best match for the specific backend - and icon type. - - For each candidate image, you need to provide: - - - the width in pixels - - the height in pixels - - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844 - on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44) - - For instance, if you have 3 candidate images (small, medium, big) of - sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup - like this: - - // the actual pixel data (RGBA8, origin top-left) - const uint32_t small[16][16] = { ... }; - const uint32_t medium[32][32] = { ... }; - const uint32_t big[64][64] = { ... }; - - const sapp_icon_desc icon_desc = { - .images = { - { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) }, - { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) }, - // ...or without the SAPP_RANGE helper macro: - { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } } - } - }; - - An sapp_icon_desc struct initialized like this can then either be applied - at application start in sokol_main: - - sapp_desc sokol_main(...) { - return (sapp_desc){ - ... - icon = icon_desc - }; - } - - ...or later by calling sapp_set_icon(): - - sapp_set_icon(&icon_desc); - - Some window icon caveats: - - - once the window icon has been updated, there's no way to go back to - the platform's default icon, this is because some platforms (Linux - and HTML5) don't switch the icon visual back to the default even if - the custom icon is deleted or removed - - on HTML5, if the sokol_app.h icon doesn't show up in the browser - tab, check that there's no traditional favicon 'link' element - is defined in the page's index.html, sokol_app.h will only - append a new favicon link element, but not delete any manually - defined favicon in the page - - For an example and test of the window icon feature, check out the the - 'icon-sapp' sample on the sokol-samples git repository. - - ONSCREEN KEYBOARD - ================= - On some platforms which don't provide a physical keyboard, sokol-app - can display the platform's integrated onscreen keyboard for text - input. To request that the onscreen keyboard is shown, call - - sapp_show_keyboard(true); - - Likewise, to hide the keyboard call: - - sapp_show_keyboard(false); - - Note that on the web platform, the keyboard can only be shown from - inside an input handler. On such platforms, sapp_show_keyboard() - will only work as expected when it is called from inside the - sokol-app event callback function. When called from other places, - an internal flag will be set, and the onscreen keyboard will be - called at the next 'legal' opportunity (when the next input event - is handled). - - OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY) - ====================================================== - In its default configuration, sokol_app.h "hijacks" the platform's - standard main() function. This was done because different platforms - have different main functions which are not compatible with - C's main() (for instance WinMain on Windows has completely different - arguments). However, this "main hijacking" posed a problem for - usage scenarios like integrating sokol_app.h with other languages than - C or C++, so an alternative SOKOL_NO_ENTRY mode has been added - in which the user code provides the platform's main function: - - - define SOKOL_NO_ENTRY before including the sokol_app.h implementation - - do *not* provide a sokol_main() function - - instead provide the standard main() function of the platform - - from the main function, call the function ```sapp_run()``` which - takes a pointer to an ```sapp_desc``` structure. - - ```sapp_run()``` takes over control and calls the provided init-, frame-, - shutdown- and event-callbacks just like in the default model, it - will only return when the application quits (or not at all on some - platforms, like emscripten) - - NOTE: SOKOL_NO_ENTRY is currently not supported on Android. - - WINDOWS CONSOLE OUTPUT - ====================== - On Windows, regular windowed applications don't show any stdout/stderr text - output, which can be a bit of a hassle for printf() debugging or generally - logging text to the console. Also, console output by default uses a local - codepage setting and thus international UTF-8 encoded text is printed - as garbage. - - To help with these issues, sokol_app.h can be configured at startup - via the following Windows-specific sapp_desc flags: - - sapp_desc.win32_console_utf8 (default: false) - When set to true, the output console codepage will be switched - to UTF-8 (and restored to the original codepage on exit) - - sapp_desc.win32_console_attach (default: false) - When set to true, stdout and stderr will be attached to the - console of the parent process (if the parent process actually - has a console). This means that if the application was started - in a command line window, stdout and stderr output will be printed - to the terminal, just like a regular command line program. But if - the application is started via double-click, it will behave like - a regular UI application, and stdout/stderr will not be visible. + void stm_setup(); + Call once before any other functions to initialize sokol_time + (this calls for instance QueryPerformanceFrequency on Windows) - sapp_desc.win32_console_create (default: false) - When set to true, a new console window will be created and - stdout/stderr will be redirected to that console window. It - doesn't matter if the application is started from the command - line or via double-click. + uint64_t stm_now(); + Get current point in time in unspecified 'ticks'. The value that + is returned has no relation to the 'wall-clock' time and is + not in a specific time unit, it is only useful to compute + time differences. - MEMORY ALLOCATION OVERRIDE - ========================== - You can override the memory allocation functions at initialization time - like this: + uint64_t stm_diff(uint64_t new, uint64_t old); + Computes the time difference between new and old. This will always + return a positive, non-zero value. - void* my_alloc(size_t size, void* user_data) { - return malloc(size); - } + uint64_t stm_since(uint64_t start); + Takes the current time, and returns the elapsed time since start + (this is a shortcut for "stm_diff(stm_now(), start)") - void my_free(void* ptr, void* user_data) { - free(ptr); - } + uint64_t stm_laptime(uint64_t* last_time); + This is useful for measuring frame time and other recurring + events. It takes the current time, returns the time difference + to the value in last_time, and stores the current time in + last_time for the next call. If the value in last_time is 0, + the return value will be zero (this usually happens on the + very first call). - sapp_desc sokol_main(int argc, char* argv[]) { - return (sapp_desc){ - // ... - .allocator = { - .alloc = my_alloc, - .free = my_free, - .user_data = ...; - } - }; - } + uint64_t stm_round_to_common_refresh_rate(uint64_t duration) + This oddly named function takes a measured frame time and + returns the closest "nearby" common display refresh rate frame duration + in ticks.

The rationale is to have a simple - countermeasure to avoid the CPU scribbling over data the GPU is currently - using, or the CPU having to wait for the GPU - - Buffer and image updates can be partial, as long as a rendering - operation only references the valid (updated) data in the - buffer or image. - - --- to append a chunk of data to a buffer resource, call: - - int sg_append_buffer(sg_buffer buf, const sg_range* data) - - The difference to sg_update_buffer() is that sg_append_buffer() - can be called multiple times per frame to append new data to the - buffer piece by piece, optionally interleaved with draw calls referencing - the previously written data. - - sg_append_buffer() returns a byte offset to the start of the - written data, this offset can be assigned to - sg_bindings.vertex_buffer_offsets[n] or - sg_bindings.index_buffer_offset - - Code example: - - for (...) { - const void* data = ...; - const int num_bytes = ...; - int offset = sg_append_buffer(buf, &(sg_range) { .ptr=data, .size=num_bytes }); - bindings.vertex_buffer_offsets[0] = offset; - sg_apply_pipeline(pip); - sg_apply_bindings(&bindings); - sg_apply_uniforms(...); - sg_draw(...); - } - - A buffer to be used with sg_append_buffer() must have been created - with SG_USAGE_DYNAMIC or SG_USAGE_STREAM. - - If the application appends more data to the buffer then fits into - the buffer, the buffer will go into the "overflow" state for the - rest of the frame. - - Any draw calls attempting to render an overflown buffer will be - silently dropped (in debug mode this will also result in a - validation error). - - You can also check manually if a buffer is in overflow-state by calling - - bool sg_query_buffer_overflow(sg_buffer buf) - - NOTE: Due to restrictions in underlying 3D-APIs, appended chunks of - data will be 4-byte aligned in the destination buffer. This means - that there will be gaps in index buffers containing 16-bit indices - when the number of indices in a call to sg_append_buffer() is - odd. This isn't a problem when each call to sg_append_buffer() - is associated with one draw call, but will be problematic when - a single indexed draw call spans several appended chunks of indices. - - --- to check at runtime for optional features, limits and pixelformat support, - call: - - sg_features sg_query_features() - sg_limits sg_query_limits() - sg_pixelformat_info sg_query_pixelformat(sg_pixel_format fmt) - - --- if you need to call into the underlying 3D-API directly, you must call: - - sg_reset_state_cache() - - ...before calling sokol_gfx functions again - - --- you can inspect the original sg_desc structure handed to sg_setup() - by calling sg_query_desc(). This will return an sg_desc struct with - the default values patched in instead of any zero-initialized values - - --- you can inspect various internal resource attributes via: - - sg_buffer_info sg_query_buffer_info(sg_buffer buf) - sg_image_info sg_query_image_info(sg_image img) - sg_shader_info sg_query_shader_info(sg_shader shd) - sg_pipeline_info sg_query_pipeline_info(sg_pipeline pip) - sg_pass_info sg_query_pass_info(sg_pass pass) - - ...please note that the returned info-structs are tied quite closely - to sokol_gfx.h internals, and may change more often than other - public API functions and structs. - - --- you can ask at runtime what backend sokol_gfx.h has been compiled - for, or whether the GLES3 backend had to fall back to GLES2 with: - - sg_backend sg_query_backend(void) - - --- you can query the default resource creation parameters through the functions - - sg_buffer_desc sg_query_buffer_defaults(const sg_buffer_desc* desc) - sg_image_desc sg_query_image_defaults(const sg_image_desc* desc) - sg_shader_desc sg_query_shader_defaults(const sg_shader_desc* desc) - sg_pipeline_desc sg_query_pipeline_defaults(const sg_pipeline_desc* desc) - sg_pass_desc sg_query_pass_defaults(const sg_pass_desc* desc) - - These functions take a pointer to a desc structure which may contain - zero-initialized items for default values. These zero-init values - will be replaced with their concrete values in the returned desc - struct. - - ON INITIALIZATION: - ================== - When calling sg_setup(), a pointer to an sg_desc struct must be provided - which contains initialization options. These options provide two types - of information to sokol-gfx: - - (1) upper bounds and limits needed to allocate various internal - data structures: - - the max number of resources of each type that can - be alive at the same time, this is used for allocating - internal pools - - the max overall size of uniform data that can be - updated per frame, including a worst-case alignment - per uniform update (this worst-case alignment is 256 bytes) - - the max size of all dynamic resource updates (sg_update_buffer, - sg_append_buffer and sg_update_image) per frame - - the max number of entries in the texture sampler cache - (how many unique texture sampler can exist at the same time) - Not all of those limit values are used by all backends, but it is - good practice to provide them none-the-less. - - (2) 3D-API "context information" (sometimes also called "bindings"): - sokol_gfx.h doesn't create or initialize 3D API objects which are - closely related to the presentation layer (this includes the "rendering - device", the swapchain, and any objects which depend on the - swapchain). These API objects (or callback functions to obtain - them, if those objects might change between frames), must - be provided in a nested sg_context_desc struct inside the - sg_desc struct. If sokol_gfx.h is used together with - sokol_app.h, have a look at the sokol_glue.h header which provides - a convenience function to get a sg_context_desc struct filled out - with context information provided by sokol_app.h - - See the documention block of the sg_desc struct below for more information. - - - UNIFORM DATA LAYOUT: - ==================== - NOTE: if you use the sokol-shdc shader compiler tool, you don't need to worry - about the following details. - - The data that's passed into the sg_apply_uniforms() function must adhere to - specific layout rules so that the GPU shader finds the uniform block - items at the right offset. - - For the D3D11 and Metal backends, sokol-gfx only cares about the size of uniform - blocks, but not about the internal layout. The data will just be copied into - a uniform/constant buffer in a single operation and it's up you to arrange the - CPU-side layout so that it matches the GPU side layout. This also means that with - the D3D11 and Metal backends you are not limited to a 'cross-platform' subset - of uniform variable types. - - If you ever only use one of the D3D11, Metal *or* WebGPU backend, you can stop reading here. - - For the GL backends, the internal layout of uniform blocks matters though, - and you are limited to a small number of uniform variable types. This is - because sokol-gfx must be able to locate the uniform block members in order - to upload them to the GPU with glUniformXXX() calls. - - To describe the uniform block layout to sokol-gfx, the following information - must be passed to the sg_make_shader() call in the sg_shader_desc struct: - - - a hint about the used packing rule (either SG_UNIFORMLAYOUT_NATIVE or - SG_UNIFORMLAYOUT_STD140) - - a list of the uniform block members types in the correct order they - appear on the CPU side - - For example if the GLSL shader has the following uniform declarations: - - uniform mat4 mvp; - uniform vec2 offset0; - uniform vec2 offset1; - uniform vec2 offset2; - - ...and on the CPU side, there's a similar C struct: - - typedef struct { - float mvp[16]; - float offset0[2]; - float offset1[2]; - float offset2[2]; - } params_t; - - ...the uniform block description in the sg_shader_desc must look like this: - - sg_shader_desc desc = { - .vs.uniform_blocks[0] = { - .size = sizeof(params_t), - .layout = SG_UNIFORMLAYOUT_NATIVE, // this is the default and can be omitted - .uniforms = { - // order must be the same as in 'params_t': - [0] = { .name = "mvp", .type = SG_UNIFORMTYPE_MAT4 }, - [1] = { .name = "offset0", .type = SG_UNIFORMTYPE_VEC2 }, - [2] = { .name = "offset1", .type = SG_UNIFORMTYPE_VEC2 }, - [3] = { .name = "offset2", .type = SG_UNIFORMTYPE_VEC2 }, - } - } - }; - - With this information sokol-gfx can now compute the correct offsets of the data items - within the uniform block struct. - - The SG_UNIFORMLAYOUT_NATIVE packing rule works fine if only the GL backends are used, - but for proper D3D11/Metal/GL a subset of the std140 layout must be used which is - described in the next section: - - - CROSS-BACKEND COMMON UNIFORM DATA LAYOUT - ======================================== - For cross-platform / cross-3D-backend code it is important that the same uniform block - layout on the CPU side can be used for all sokol-gfx backends. To achieve this, - a common subset of the std140 layout must be used: - - - The uniform block layout hint in sg_shader_desc must be explicitely set to - SG_UNIFORMLAYOUT_STD140. - - Only the following GLSL uniform types can be used (with their associated sokol-gfx enums): - - float => SG_UNIFORMTYPE_FLOAT - - vec2 => SG_UNIFORMTYPE_FLOAT2 - - vec3 => SG_UNIFORMTYPE_FLOAT3 - - vec4 => SG_UNIFORMTYPE_FLOAT4 - - int => SG_UNIFORMTYPE_INT - - ivec2 => SG_UNIFORMTYPE_INT2 - - ivec3 => SG_UNIFORMTYPE_INT3 - - ivec4 => SG_UNIFORMTYPE_INT4 - - mat4 => SG_UNIFORMTYPE_MAT4 - - Alignment for those types must be as follows (in bytes): - - float => 4 - - vec2 => 8 - - vec3 => 16 - - vec4 => 16 - - int => 4 - - ivec2 => 8 - - ivec3 => 16 - - ivec4 => 16 - - mat4 => 16 - - Arrays are only allowed for the following types: vec4, int4, mat4. - - Note that the HLSL cbuffer layout rules are slightly different from the - std140 layout rules, this means that the cbuffer declarations in HLSL code - must be tweaked so that the layout is compatible with std140. - - The by far easiest way to tacke the common uniform block layout problem is - to use the sokol-shdc shader cross-compiler tool! - - - BACKEND-SPECIFIC TOPICS: - ======================== - --- The GL backends need to know about the internal structure of uniform - blocks, and the texture sampler-name and -type. The uniform layout details - are described in the UNIFORM DATA LAYOUT section above. - - // uniform block structure and texture image definition in sg_shader_desc: - sg_shader_desc desc = { - // uniform block description (size and internal structure) - .vs.uniform_blocks[0] = { - ... - }, - // one texture on the fragment-shader-stage, GLES2/WebGL needs name and image type - .fs.images[0] = { .name="tex", .type=SG_IMAGETYPE_ARRAY } - ... - }; - - --- the Metal and D3D11 backends only need to know the size of uniform blocks, - not their internal member structure, and they only need to know - the type of a texture sampler, not its name: - - sg_shader_desc desc = { - .vs.uniform_blocks[0].size = sizeof(params_t), - .fs.images[0].type = SG_IMAGETYPE_ARRAY, - ... - }; - - --- when creating a shader object, GLES2/WebGL need to know the vertex - attribute names as used in the vertex shader: - - sg_shader_desc desc = { - .attrs = { - [0] = { .name="position" }, - [1] = { .name="color1" } - } - }; - - The vertex attribute names provided when creating a shader will be - used later in sg_create_pipeline() for matching the vertex layout - to vertex shader inputs. - - --- on D3D11 you need to provide a semantic name and semantic index in the - shader description struct instead (see the D3D11 documentation on - D3D11_INPUT_ELEMENT_DESC for details): - - sg_shader_desc desc = { - .attrs = { - [0] = { .sem_name="POSITION", .sem_index=0 } - [1] = { .sem_name="COLOR", .sem_index=1 } - } - }; - - The provided semantic information will be used later in sg_create_pipeline() - to match the vertex layout to vertex shader inputs. - - --- on D3D11, and when passing HLSL source code (instead of byte code) to shader - creation, you can optionally define the shader model targets on the vertex - stage: - - sg_shader_Desc desc = { - .vs = { - ... - .d3d11_target = "vs_5_0" - }, - .fs = { - ... - .d3d11_target = "ps_5_0" - } - }; - - The default targets are "ps_4_0" and "fs_4_0". Note that those target names - are only used when compiling shaders from source. They are ignored when - creating a shader from bytecode. - - --- on Metal, GL 3.3 or GLES3/WebGL2, you don't need to provide an attribute - name or semantic name, since vertex attributes can be bound by their slot index - (this is mandatory in Metal, and optional in GL): - - sg_pipeline_desc desc = { - .layout = { - .attrs = { - [0] = { .format=SG_VERTEXFORMAT_FLOAT3 }, - [1] = { .format=SG_VERTEXFORMAT_FLOAT4 } - } - } - }; - - WORKING WITH CONTEXTS - ===================== - sokol-gfx allows to switch between different rendering contexts and - associate resource objects with contexts. This is useful to - create GL applications that render into multiple windows. - - A rendering context keeps track of all resources created while - the context is active. When the context is destroyed, all resources - "belonging to the context" are destroyed as well. - - A default context will be created and activated implicitly in - sg_setup(), and destroyed in sg_shutdown(). So for a typical application - which *doesn't* use multiple contexts, nothing changes, and calling - the context functions isn't necessary. - - Three functions have been added to work with contexts: - - --- sg_context sg_setup_context(): - This must be called once after a GL context has been created and - made active. - - --- void sg_activate_context(sg_context ctx) - This must be called after making a different GL context active. - Apart from 3D-API-specific actions, the call to sg_activate_context() - will internally call sg_reset_state_cache(). - - --- void sg_discard_context(sg_context ctx) - This must be called right before a GL context is destroyed and - will destroy all resources associated with the context (that - have been created while the context was active) The GL context must be - active at the time sg_discard_context(sg_context ctx) is called. - - Also note that resources (buffers, images, shaders and pipelines) must - only be used or destroyed while the same GL context is active that - was also active while the resource was created (an exception is - resource sharing on GL, such resources can be used while - another context is active, but must still be destroyed under - the same context that was active during creation). - - For more information, check out the multiwindow-glfw sample: - - https://github.com/floooh/sokol-samples/blob/master/glfw/multiwindow-glfw.c - - TRACE HOOKS: - ============ - sokol_gfx.h optionally allows to install "trace hook" callbacks for - each public API functions. When a public API function is called, and - a trace hook callback has been installed for this function, the - callback will be invoked with the parameters and result of the function. - This is useful for things like debugging- and profiling-tools, or - keeping track of resource creation and destruction. - - To use the trace hook feature: - - --- Define SOKOL_TRACE_HOOKS before including the implementation. - - --- Setup an sg_trace_hooks structure with your callback function - pointers (keep all function pointers you're not interested - in zero-initialized), optionally set the user_data member - in the sg_trace_hooks struct. - - --- Install the trace hooks by calling sg_install_trace_hooks(), - the return value of this function is another sg_trace_hooks - struct which contains the previously set of trace hooks. - You should keep this struct around, and call those previous - functions pointers from your own trace callbacks for proper - chaining. - - As an example of how trace hooks are used, have a look at the - imgui/sokol_gfx_imgui.h header which implements a realtime - debugging UI for sokol_gfx.h on top of Dear ImGui. - - A NOTE ON PORTABLE PACKED VERTEX FORMATS: - ========================================= - There are two things to consider when using packed - vertex formats like UBYTE4, SHORT2, etc which need to work - across all backends: - - - D3D11 can only convert *normalized* vertex formats to - floating point during vertex fetch, normalized formats - have a trailing 'N', and are "normalized" to a range - -1.0..+1.0 (for the signed formats) or 0.0..1.0 (for the - unsigned formats): - - - SG_VERTEXFORMAT_BYTE4N - - SG_VERTEXFORMAT_UBYTE4N - - SG_VERTEXFORMAT_SHORT2N - - SG_VERTEXFORMAT_USHORT2N - - SG_VERTEXFORMAT_SHORT4N - - SG_VERTEXFORMAT_USHORT4N - - D3D11 will not convert *non-normalized* vertex formats to floating point - vertex shader inputs, those can only be uses with the *ivecn* vertex shader - input types when D3D11 is used as backend (GL and Metal can use both formats) - - - SG_VERTEXFORMAT_BYTE4, - - SG_VERTEXFORMAT_UBYTE4 - - SG_VERTEXFORMAT_SHORT2 - - SG_VERTEXFORMAT_SHORT4 - - - WebGL/GLES2 cannot use integer vertex shader inputs (int or ivecn) - - - SG_VERTEXFORMAT_UINT10_N2 is not supported on WebGL/GLES2 - - So for a vertex input layout which works on all platforms, only use the following - vertex formats, and if needed "expand" the normalized vertex shader - inputs in the vertex shader by multiplying with 127.0, 255.0, 32767.0 or - 65535.0: - - - SG_VERTEXFORMAT_FLOAT, - - SG_VERTEXFORMAT_FLOAT2, - - SG_VERTEXFORMAT_FLOAT3, - - SG_VERTEXFORMAT_FLOAT4, - - SG_VERTEXFORMAT_BYTE4N, - - SG_VERTEXFORMAT_UBYTE4N, - - SG_VERTEXFORMAT_SHORT2N, - - SG_VERTEXFORMAT_USHORT2N - - SG_VERTEXFORMAT_SHORT4N, - - SG_VERTEXFORMAT_USHORT4N - - - MEMORY ALLOCATION OVERRIDE - ========================== - You can override the memory allocation functions at initialization time - like this: - - void* my_alloc(size_t size, void* user_data) { - return malloc(size); - } - - void my_free(void* ptr, void* user_data) { - free(ptr); - } - - ... - sg_setup(&(sg_desc){ - // ... - .allocator = { - .alloc = my_alloc, - .free = my_free, - .user_data = ...; - } - }); - ... - - If no overrides are provided, malloc and free will be used. - - This only affects memory allocation calls done by sokol_gfx.h - itself though, not any allocations in OS libraries. - - - TODO: - ==== - - talk about asynchronous resource creation - - zlib/libpng license - - Copyright (c) 2018 Andre Weissflog - - This software is provided 'as-is', without any express or implied warranty. - In no event will the authors be held liable for any damages arising from the - use of this software. - - Permission is granted to anyone to use this software for any purpose, - including commercial applications, and to alter it and redistribute it - freely, subject to the following restrictions: - - 1.

In this mode, it declares a -// single public symbol, STB_TexteditState, which encapsulates the current -// state of a text widget (except for the string, which you will store -// separately). -// -// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a -// primitive type that defines a single character (e.g. char, wchar_t, etc). -// -// To save space or increase undo-ability, you can optionally define the -// following things that are used by the undo system: -// -// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// If you don't define these, they are set to permissive types and -// moderate sizes.

You will then -// need to provide your own APIs in the same file which will access the -// static functions. -// -// The basic concept is that you provide a "string" object which -// behaves like an array of characters. stb_textedit uses indices to -// refer to positions in the string, implicitly representing positions -// in the displayed textedit.

For example, -// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN -// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, -// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the -// API below. The control keys will only match WM_KEYDOWN events because of the -// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN -// bit so it only decodes WM_CHAR events. -// -// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed -// row of characters assuming they start on the i'th character--the width and -// the height and the number of characters consumed. This allows this library -// to traverse the entire layout incrementally. You need to compute word-wrapping -// here. -// -// Each textfield keeps its own insert mode state, which is not how normal -// applications work. To keep an app-wide insert mode, update/copy the -// "insert_mode" field of STB_TexteditState before/after calling API functions. -// -// API -// -// void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line) -// -// void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// int stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state) -// int stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len) -// void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key) -// -// Each of these functions potentially updates the string and updates the -// state. -// -// initialize_state: -// set the textedit state to a known good default state when initially -// constructing the textedit. -// -// click: -// call this with the mouse x,y on a mouse down; it will update the cursor -// and reset the selection start/end to the cursor point. the x,y must -// be relative to the text widget, with (0,0) being the top left. -// -// drag: -// call this with the mouse x,y on a mouse drag/up; it will update the -// cursor and the selection end point -// -// cut: -// call this to delete the current selection; returns true if there was -// one. you should FIRST copy the current selection to the system paste buffer. -// (To copy, just copy the current selection out of the string yourself.) -// -// paste: -// call this to paste text at the current cursor point or over the current -// selection if there is one. -// -// key: -// call this for keyboard inputs sent to the textfield. you can use it -// for "key down" events or for "translated" key events. if you need to -// do both (as in Win32), or distinguish Unicode characters from control -// inputs, set a high bit to distinguish the two; then you can define the -// various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit -// set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is -// clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to -// anything other type you wante before including. -// -// -// When rendering, you can read the cursor position and selection state from -// the STB_TexteditState. -// -// -// Notes: -// -// This is designed to be usable in IMGUI, so it allows for the possibility of -// running in an IMGUI that has NOT cached the multi-line layout. For this -// reason, it provides an interface that is compatible with computing the -// layout incrementally--we try to make sure we make as few passes through -// as possible. (For example, to locate the mouse pointer in the text, we -// could define functions that return the X and Y positions of characters -// and binary search Y and then X, but if we're doing dynamic layout this -// will run the layout algorithm many times, so instead we manually search -// forward in one pass. Similar logic applies to e.g. up-arrow and -// down-arrow movement.) -// -// If it's run in a widget that *has* cached the layout, then this is less -// efficient, but it's not horrible on modern computers. But you wouldn't -// want to edit million-line files with it. - - -//////////////////////////////////////////////////////////////////////////// -//////////////////////////////////////////////////////////////////////////// -//// -//// Header-file mode -//// -//// - -#ifndef INCLUDE_STB_TEXTEDIT_H -#define INCLUDE_STB_TEXTEDIT_H - -//////////////////////////////////////////////////////////////////////// -// -// STB_TexteditState -// -// Definition of STB_TexteditState which you should store -// per-textfield;

Thus, anti-aliasing of intersecting shapes may look wrong. If -// this turns out to be a problem, you can re-enable the old rasterizer with -// #define STBTT_RASTERIZER_VERSION 1 -// which will incur about a 15% speed hit. -// -// ADDITIONAL DOCUMENTATION -// -// Immediately after this block comment are a series of sample programs. -// -// After the sample programs is the "header file" section. This section -// includes documentation for each API function. -// -// Some important concepts to understand to use this library: -// -// Codepoint -// Characters are defined by unicode codepoints, e.g. 65 is -// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is -// the hiragana for "ma". -// -// Glyph -// A visual character shape (every codepoint is rendered as -// some glyph) -// -// Glyph index -// A font-specific integer ID representing a glyph -// -// Baseline -// Glyph shapes are defined relative to a baseline, which is the -// bottom of uppercase characters. Characters extend both above -// and below the baseline. -// -// Current Point -// As you draw text to the screen, you keep track of a "current point" -// which is the origin of each character. The current point's vertical -// position is the baseline. Even "baked fonts" use this model. -// -// Vertical Font Metrics -// The vertical qualities of the font, used to vertically position -// and space the characters. See docs for stbtt_GetFontVMetrics. -// -// Font Size in Pixels or Points -// The preferred interface for specifying font sizes in stb_truetype -// is to specify how tall the font's vertical extent should be in pixels. -// If that sounds good enough, skip the next paragraph. -// -// Most font APIs instead use "points", which are a common typographic -// measurement for describing font size, defined as 72 points per inch. -// stb_truetype provides a point API for compatibility. However, true -// "per inch" conventions don't make much sense on computer displays -// since different monitors have different number of pixels per -// inch. For example, Windows traditionally uses a convention that -// there are 96 pixels per inch, thus making 'inch' measurements have -// nothing to do with inches, and thus effectively defining a point to -// be 1.333 pixels. Additionally, the TrueType font data provides -// an explicit scale factor to scale a given font's glyphs to points, -// but the author has observed that this scale factor is often wrong -// for non-commercial fonts, thus making fonts scaled in points -// according to the TrueType spec incoherently sized in practice. -// -// DETAILED USAGE: -// -// Scale: -// Select how high you want the font to be, in points or pixels. -// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute -// a scale factor SF that will be used by all other functions. -// -// Baseline: -// You need to select a y-coordinate that is the baseline of where -// your text will appear. Call GetFontBoundingBox to get the baseline-relative -// bounding box for all characters. SF*-y0 will be the distance in pixels -// that the worst-case character could extend above the baseline, so if -// you want the top edge of characters to appear at the top of the -// screen where y=0, then you would set the baseline to SF*-y0. -// -// Current point: -// Set the current point where the first character will appear. The -// first character could extend left of the current point; this is font -// dependent. You can either choose a current point that is the leftmost -// point and hope, or add some padding, or check the bounding box or -// left-side-bearing of the first character to be displayed and set -// the current point based on that. -// -// Displaying a character: -// Compute the bounding box of the character. It will contain signed values -// relative to . I.e. if it returns x0,y0,x1,y1, -// then the character should be displayed in the rectangle from -// to = 32 && *text < 128) { - stbtt_aligned_quad q; - stbtt_GetBakedQuad(cdata, 512,512, *text-32, &x,&y,&q,1);//1=opengl & d3d10+,0=d3d9 - glTexCoord2f(q.s0,q.t0); glVertex2f(q.x0,q.y0); - glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y0); - glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y1); - glTexCoord2f(q.s0,q.t1); glVertex2f(q.x0,q.y1); - } - ++text; - } - glEnd(); -} -#endif -// -// -////////////////////////////////////////////////////////////////////////////// -// -// Complete program (this compiles): get a single bitmap, print as ASCII art -// -#if 0 -#include -#define STB_TRUETYPE_IMPLEMENTATION // force following include to generate implementation -#include "stb_truetype.h" - -char ttf_buffer[1<<25]; - -int main(int argc, char **argv) -{ - stbtt_fontinfo font; - unsigned char *bitmap; - int w,h,i,j,c = (argc > 1 ? atoi(argv[1]) : 'a'), s = (argc > 2 ? atoi(argv[2]) : 20); - - fread(ttf_buffer, 1, 1<<25, fopen(argc > 3 ? argv[3] : "c:/windows/fonts/arialbd.ttf", "rb")); - - stbtt_InitFont(&font, ttf_buffer, stbtt_GetFontOffsetForIndex(ttf_buffer,0)); - bitmap = stbtt_GetCodepointBitmap(&font, 0,stbtt_ScaleForPixelHeight(&font, s), c, &w, &h, 0,0); - - for (j=0; j < h; ++j) { - for (i=0; i < w; ++i) - putchar(" .:ioVM@"[bitmap[j*w+i]>>5]); - putchar('\n'); - } - return 0; -} -#endif -// -// Output: -// -// .ii. -// @@@@@@. -// V@Mio@@o -// :i.

TableUpdateLayout() [Internal] followup to BeginTable(): setup everything: widths, columns positions, clipping rectangles. Automatically called by the FIRST call to TableNextRow() or TableHeadersRow(). -// | TableSetupDrawChannels() - setup ImDrawList channels -// | TableUpdateBorders() - detect hovering columns for resize, ahead of contents submission -// | TableDrawContextMenu() - draw right-click context menu -//----------------------------------------------------------------------------- -// - TableHeadersRow() or TableHeader() user submit a headers row (optional) -// | TableSortSpecsClickColumn() - when left-clicked: alter sort order and sort direction -// | TableOpenContextMenu() - when right-clicked: trigger opening of the default context menu -// - TableGetSortSpecs() user queries updated sort specs (optional, generally after submitting headers) -// - TableNextRow() user begin into a new row (also automatically called by TableHeadersRow()) -// | TableEndRow() - finish existing row -// | TableBeginRow() - add a new row -// - TableSetColumnIndex() / TableNextColumn() user begin into a cell -// | TableEndCell() - close existing column/cell -// | TableBeginCell() - enter into current column/cell -// - [...] user emit contents -//----------------------------------------------------------------------------- -// - EndTable() user ends the table -// | TableDrawBorders() - draw outer borders, inner vertical borders -// | TableMergeDrawChannels() - merge draw channels if clipping isn't required -// | EndChild() - (if ScrollX/ScrollY is set) -//----------------------------------------------------------------------------- - -//----------------------------------------------------------------------------- -// TABLE SIZING -//----------------------------------------------------------------------------- -// (Read carefully because this is subtle but it does make sense!) -//----------------------------------------------------------------------------- -// About 'outer_size': -// Its meaning needs to differ slightly depending on if we are using ScrollX/ScrollY flags. -// Default value is ImVec2(0.0f, 0.0f). -// X -// - outer_size.x <= 0.0f -> Right-align from window/work-rect right-most edge. With -FLT_MIN or 0.0f will align exactly on right-most edge. -// - outer_size.x > 0.0f -> Set Fixed width. -// Y with ScrollX/ScrollY disabled: we output table directly in current window -// - outer_size.y < 0.0f -> Bottom-align (but will auto extend, unless _NoHostExtendY is set). Not meaningful is parent window can vertically scroll. -// - outer_size.y = 0.0f -> No minimum height (but will auto extend, unless _NoHostExtendY is set) -// - outer_size.y > 0.0f -> Set Minimum height (but will auto extend, unless _NoHostExtenY is set) -// Y with ScrollX/ScrollY enabled: using a child window for scrolling -// - outer_size.y < 0.0f -> Bottom-align. Not meaningful is parent window can vertically scroll. -// - outer_size.y = 0.0f -> Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window. -// - outer_size.y > 0.0f -> Set Exact height. Recommended when using Scrolling on any axis. -//----------------------------------------------------------------------------- -// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags. -// Important to that note how the two flags have slightly different behaviors! -// - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used. -// - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible. -// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height. -// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not easily noticeable) -//----------------------------------------------------------------------------- -// About 'inner_width': -// With ScrollX disabled: -// - inner_width -> *ignored* -// With ScrollX enabled: -// - inner_width < 0.0f -> *illegal* fit in known width (right align from outer_size.x) <-- weird -// - inner_width = 0.0f -> fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns. -// - inner_width > 0.0f -> override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space! -//----------------------------------------------------------------------------- -// Details: -// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept -// of "available space" doesn't make sense. -// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding -// of what the value does. -//----------------------------------------------------------------------------- - -//----------------------------------------------------------------------------- -// COLUMNS SIZING POLICIES -//----------------------------------------------------------------------------- -// About overriding column sizing policy and width/weight with TableSetupColumn(): -// We use a default parameter of 'init_width_or_weight == -1'. -// - with ImGuiTableColumnFlags_WidthFixed, init_width <= 0 (default) --> width is automatic -// - with ImGuiTableColumnFlags_WidthFixed, init_width > 0 (explicit) --> width is custom -// - with ImGuiTableColumnFlags_WidthStretch, init_weight <= 0 (default) --> weight is 1.0f -// - with ImGuiTableColumnFlags_WidthStretch, init_weight > 0 (explicit) --> weight is custom -// Widths are specified _without_ CellPadding. If you specify a width of 100.0f, the column will be cover (100.0f + Padding * 2.0f) -// and you can fit a 100.0f wide item in it without clipping and with full padding. -//----------------------------------------------------------------------------- -// About default sizing policy (if you don't specify a ImGuiTableColumnFlags_WidthXXXX flag) -// - with Table policy ImGuiTableFlags_SizingFixedFit --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is equal to contents width -// - with Table policy ImGuiTableFlags_SizingFixedSame --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is max of all contents width -// - with Table policy ImGuiTableFlags_SizingStretchSame --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is 1.0f -// - with Table policy ImGuiTableFlags_SizingStretchWeight --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is proportional to contents -// Default Width and default Weight can be overridden when calling TableSetupColumn(). -//----------------------------------------------------------------------------- -// About mixing Fixed/Auto and Stretch columns together: -// - the typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns. -// - using mixed policies with ScrollX does not make much sense, as using Stretch columns with ScrollX does not make much sense in the first place! -// that is, unless 'inner_width' is passed to BeginTable() to explicitly provide a total width to layout columns in. -// - when using ImGuiTableFlags_SizingFixedSame with mixed columns, only the Fixed/Auto columns will match their widths to the width of the maximum contents. -// - when using ImGuiTableFlags_SizingStretchSame with mixed columns, only the Stretch columns will match their weight/widths. -//----------------------------------------------------------------------------- -// About using column width: -// If a column is manual resizable or has a width specified with TableSetupColumn(): -// - you may use GetContentRegionAvail().x to query the width available in a given column. -// - right-side alignment features such as SetNextItemWidth(-x) or PushItemWidth(-x) will rely on this width. -// If the column is not resizable and has no width specified with TableSetupColumn(): -// - its width will be automatic and be set to the max of items submitted. -// - therefore you generally cannot have ALL items of the columns use e.g. SetNextItemWidth(-FLT_MIN). -// - but if the column has one or more items of known/fixed size, this will become the reference width used by SetNextItemWidth(-FLT_MIN). -//----------------------------------------------------------------------------- - - -//----------------------------------------------------------------------------- -// TABLES CLIPPING/CULLING -//----------------------------------------------------------------------------- -// About clipping/culling of Rows in Tables: -// - For large numbers of rows, it is recommended you use ImGuiListClipper to only submit visible rows. -// ImGuiListClipper is reliant on the fact that rows are of equal height. -// See 'Demo->Tables->Vertical Scrolling' or 'Demo->Tables->Advanced' for a demo of using the clipper. -// - Note that auto-resizing columns don't play well with using the clipper. -// By default a table with _ScrollX but without _Resizable will have column auto-resize. -// So, if you want to use the clipper, make sure to either enable _Resizable, either setup columns width explicitly with _WidthFixed. -//----------------------------------------------------------------------------- -// About clipping/culling of Columns in Tables: -// - Both TableSetColumnIndex() and TableNextColumn() return true when the column is visible or performing -// width measurements. Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know -// it is not going to contribute to row height. -// In many situations, you may skip submitting contents for every column but one (e.g. the first one). -// - Case A: column is not hidden by user, and at least partially in sight (most common case). -// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output. -// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.). -// -// [A] [B] [C] -// TableNextColumn(): true false false -> [userland] when TableNextColumn() / TableSetColumnIndex() return false, user can skip submitting items but only if the column doesn't contribute to row height. -// SkipItems: false false true -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output. -// ClipRect: normal zero-width zero-width -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way. -// ImDrawList output: normal dummy dummy -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway). -// -// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row. -// However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer. -//----------------------------------------------------------------------------- -// About clipping/culling of whole Tables: -// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false. -//----------------------------------------------------------------------------- - -//----------------------------------------------------------------------------- -// [SECTION] Header mess -//----------------------------------------------------------------------------- - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#ifndef IMGUI_DISABLE - -#ifndef IMGUI_DEFINE_MATH_OPERATORS -#define IMGUI_DEFINE_MATH_OPERATORS -#endif - - -// System includes -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include // intptr_t -#else -#include // intptr_t -#endif - -// Visual Studio warnings -#ifdef _MSC_VER -#pragma warning (disable: 4127) // condition expression is constant -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen -#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later -#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types -#endif -#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.

In this mode, it declares a -// single public symbol, STB_TexteditState, which encapsulates the current -// state of a text widget (except for the string, which you will store -// separately). -// -// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a -// primitive type that defines a single character (e.g. char, wchar_t, etc). -// -// To save space or increase undo-ability, you can optionally define the -// following things that are used by the undo system: -// -// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// If you don't define these, they are set to permissive types and -// moderate sizes. The undo system does no memory allocations, so -// it grows STB_TexteditState by the worst-case storage which is (in bytes): -// -// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT -// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHARCOUNT -// -// -// Implementation mode: -// -// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it -// will compile the implementation of the text edit widget, depending -// on a large number of symbols which must be defined before the include. -// -// The implementation is defined only as static functions. You will then -// need to provide your own APIs in the same file which will access the -// static functions. -// -// The basic concept is that you provide a "string" object which -// behaves like an array of characters. stb_textedit uses indices to -// refer to positions in the string, implicitly representing positions -// in the displayed textedit. This is true for both plain text and -// rich text; even with rich text stb_truetype interacts with your -// code as if there was an array of all the displayed characters. -// -// Symbols that must be the same in header-file and implementation mode: -// -// STB_TEXTEDIT_CHARTYPE the character type -// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// Symbols you must define for implementation mode: -// -// STB_TEXTEDIT_STRING the type of object representing a string being edited, -// typically this is a wrapper object with other data you need -// -// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) -// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters -// starting from character #n (see discussion below) -// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character -// to the xpos of the i+1'th char for a line of characters -// starting at character #n (i.e. accounts for kerning -// with previous char) -// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character -// (return type is int, -1 means not valid to insert) -// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based -// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize -// as manually wordwrapping for end-of-line positioning -// -// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i -// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) -// -// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key -// -// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left -// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right -// STB_TEXTEDIT_K_UP keyboard input to move cursor up -// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down -// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page -// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page -// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME -// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END -// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME -// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END -// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor -// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor -// STB_TEXTEDIT_K_UNDO keyboard input to perform undo -// STB_TEXTEDIT_K_REDO keyboard input to perform redo -// -// Optional: -// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode -// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), -// required for default WORDLEFT/WORDRIGHT handlers -// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to -// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to -// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT -// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT -// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line -// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line -// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text -// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text -// -// Keyboard input must be encoded as a single integer value; e.g. a character code -// and some bitflags that represent shift states. to simplify the interface, SHIFT must -// be a bitflag, so we can test the shifted state of cursor movements to allow selection, -// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. -// -// You can encode other things, such as CONTROL or ALT, in additional bits, and -// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, -// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN -// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, -// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the -// API below. The control keys will only match WM_KEYDOWN events because of the -// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN -// bit so it only decodes WM_CHAR events. -// -// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed -// row of characters assuming they start on the i'th character--the width and -// the height and the number of characters consumed. This allows this library -// to traverse the entire layout incrementally. You need to compute word-wrapping -// here. -// -// Each textfield keeps its own insert mode state, which is not how normal -// applications work. To keep an app-wide insert mode, update/copy the -// "insert_mode" field of STB_TexteditState before/after calling API functions. -// -// API -// -// void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line) -// -// void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// int stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state) -// int stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len) -// void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key) -// -// Each of these functions potentially updates the string and updates the -// state. -// -// initialize_state: -// set the textedit state to a known good default state when initially -// constructing the textedit. -// -// click: -// call this with the mouse x,y on a mouse down; it will update the cursor -// and reset the selection start/end to the cursor point. the x,y must -// be relative to the text widget, with (0,0) being the top left. -// -// drag: -// call this with the mouse x,y on a mouse drag/up; it will update the -// cursor and the selection end point -// -// cut: -// call this to delete the current selection; returns true if there was -// one. you should FIRST copy the current selection to the system paste buffer. -// (To copy, just copy the current selection out of the string yourself.) -// -// paste: -// call this to paste text at the current cursor point or over the current -// selection if there is one. -// -// key: -// call this for keyboard inputs sent to the textfield. you can use it -// for "key down" events or for "translated" key events. if you need to -// do both (as in Win32), or distinguish Unicode characters from control -// inputs, set a high bit to distinguish the two; then you can define the -// various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit -// set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is -// clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to -// anything other type you wante before including. -// -// -// When rendering, you can read the cursor position and selection state from -// the STB_TexteditState. -// -// -// Notes: -// -// This is designed to be usable in IMGUI, so it allows for the possibility of -// running in an IMGUI that has NOT cached the multi-line layout. For this -// reason, it provides an interface that is compatible with computing the -// layout incrementally--we try to make sure we make as few passes through -// as possible. (For example, to locate the mouse pointer in the text, we -// could define functions that return the X and Y positions of characters -// and binary search Y and then X, but if we're doing dynamic layout this -// will run the layout algorithm many times, so instead we manually search -// forward in one pass. Similar logic applies to e.g. up-arrow and -// down-arrow movement.) -// -// If it's run in a widget that *has* cached the layout, then this is less -// efficient, but it's not horrible on modern computers. But you wouldn't -// want to edit million-line files with it. - - -//////////////////////////////////////////////////////////////////////////// -//////////////////////////////////////////////////////////////////////////// -//// -//// Header-file mode -//// -//// - -#ifndef INCLUDE_STB_TEXTEDIT_H -#define INCLUDE_STB_TEXTEDIT_H - -//////////////////////////////////////////////////////////////////////// -// -// STB_TexteditState -// -// Definition of STB_TexteditState which you should store -// per-textfield;

Think again! It is the most useful reference code that you and other -// coders will want to refer to and call. Have the ImGui::ShowDemoWindow() function wired in an always-available -// debug menu of your game/app! Removing this file from your project is hindering access to documentation for everyone -// in your team, likely leading you to poorer usage of the library. -// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow(). -// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be -// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty. -// In another situation, whenever you have Dear ImGui available you probably want this to be available for reference. -// Thank you, -// -Your beloved friend, imgui_demo.cpp (which you won't delete) - -// Message to beginner C/C++ programmers about the meaning of the 'static' keyword: -// In this demo code, we frequently use 'static' variables inside functions. A static variable persists across calls, -// so it is essentially like a global variable but declared inside the scope of the function. We do this as a way to -// gather code and data in the same place, to make the demo source code faster to read, faster to write, and smaller -// in size. It also happens to be a convenient way of storing simple UI related information as long as your function -// doesn't need to be reentrant or used in multiple threads. This might be a pattern you will want to use in your code, -// but most of the real data you would be editing is likely going to be stored outside your functions. - -// The Demo code in this file is designed to be easy to copy-and-paste into your application! -// Because of this: -// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace. -// - We try to declare static variables in the local scope, as close as possible to the code using them. -// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API. -// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided -// by imgui_internal.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional -// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h. -// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp. - -// Navigating this file: -// - In Visual Studio IDE: CTRL+comma ("Edit.GoToAll") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot. -// - With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments. - -/* - -Index of this file: - -// [SECTION] Forward Declarations, Helpers -// [SECTION] Demo Window / ShowDemoWindow() -// - sub section: ShowDemoWindowWidgets() -// - sub section: ShowDemoWindowLayout() -// - sub section: ShowDemoWindowPopups() -// - sub section: ShowDemoWindowTables() -// - sub section: ShowDemoWindowMisc() -// [SECTION] About Window / ShowAboutWindow() -// [SECTION] Style Editor / ShowStyleEditor() -// [SECTION] Example App: Main Menu Bar / ShowExampleAppMainMenuBar() -// [SECTION] Example App: Debug Console / ShowExampleAppConsole() -// [SECTION] Example App: Debug Log / ShowExampleAppLog() -// [SECTION] Example App: Simple Layout / ShowExampleAppLayout() -// [SECTION] Example App: Property Editor / ShowExampleAppPropertyEditor() -// [SECTION] Example App: Long Text / ShowExampleAppLongText() -// [SECTION] Example App: Auto Resize / ShowExampleAppAutoResize() -// [SECTION] Example App: Constrained Resize / ShowExampleAppConstrainedResize() -// [SECTION] Example App: Simple overlay / ShowExampleAppSimpleOverlay() -// [SECTION] Example App: Fullscreen window / ShowExampleAppFullscreen() -// [SECTION] Example App: Manipulating window titles / ShowExampleAppWindowTitles() -// [SECTION] Example App: Custom Rendering using ImDrawList API / ShowExampleAppCustomRendering() -// [SECTION] Example App: Documents Handling / ShowExampleAppDocuments() - -*/ - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#ifndef IMGUI_DISABLE - -// System includes -#include // toupper -#include // INT_MIN, INT_MAX -#include // sqrtf, powf, cosf, sinf, floorf, ceilf -#include // vsnprintf, sscanf, printf -#include // NULL, malloc, free, atoi -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include // intptr_t -#else -#include // intptr_t -#endif - -// Visual Studio warnings -#ifdef _MSC_VER -#pragma warning (disable: 4127) // condition expression is constant -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen -#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.

See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://dearimgui.org/controls_sheets - - - PROGRAMMER GUIDE - ================ - - READ FIRST - ---------- - - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki) - - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction or - destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs. - - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. - - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. - - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). - You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. - - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. - For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, - where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. - - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. - - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. - - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). - If you get an assert, read the messages and comments around the assert. - - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. - - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. - See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. - However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. - - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). - - - HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI - ---------------------------------------------- - - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) - - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". - - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. - - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. - If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed - from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will - likely be a comment about it. Please report any issue to the GitHub page! - - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. - - Try to keep your copy of Dear ImGui reasonably up to date. - - - GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE - --------------------------------------------------------------- - - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. - - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. - - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. - It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL). - - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. - - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. - - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. - Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" - phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). - - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. - - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. - - - HOW A SIMPLE APPLICATION MAY LOOK LIKE - -------------------------------------- - EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). - The sub-folders in examples/ contain examples applications following this structure. - - // Application init: create a dear imgui context, setup some options, load fonts - ImGui::CreateContext(); - ImGuiIO& io = ImGui::GetIO(); - // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. - // TODO: Fill optional fields of the io structure later. - // TODO: Load TTF/OTF fonts if you don't want to use the default font. - - // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) - ImGui_ImplWin32_Init(hwnd); - ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); - - // Application main loop - while (true) - { - // Feed inputs to dear imgui, start new frame - ImGui_ImplDX11_NewFrame(); - ImGui_ImplWin32_NewFrame(); - ImGui::NewFrame(); - - // Any application code here - ImGui::Text("Hello, world!"); - - // Render dear imgui into screen - ImGui::Render(); - ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); - g_pSwapChain->Present(1, 0); - } - - // Shutdown - ImGui_ImplDX11_Shutdown(); - ImGui_ImplWin32_Shutdown(); - ImGui::DestroyContext(); - - EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE - - // Application init: create a dear imgui context, setup some options, load fonts - ImGui::CreateContext(); - ImGuiIO& io = ImGui::GetIO(); - // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. - // TODO: Fill optional fields of the io structure later. - // TODO: Load TTF/OTF fonts if you don't want to use the default font. - - // Build and load the texture atlas into a texture - // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) - int width, height; - unsigned char* pixels = NULL; - io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); - - // At this point you've got the texture data and you need to upload that to your graphic system: - // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. - // This will be passed back to your via the renderer.

GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer + pcmd->IdxOffset, vtx_buffer, pcmd->VtxOffset); - } - } - } - } - - - USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS - ------------------------------------------ - - The gamepad/keyboard navigation is fairly functional and keeps being improved. - - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse! - - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787 - - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. - - Keyboard: - - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable. - - Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() calls. - - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), - the io.WantCaptureKeyboard flag will be set. For more advanced uses, you may want to read from: - - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. - - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). - - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. - Please reach out if you think the game vs navigation input sharing could be improved. - - Gamepad: - - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. - - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys. - For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly. - Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). - - Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() + io.AddKeyAnalogEvent() calls. - - BEFORE 1.87, BACKENDS USED TO WRITE DIRECTLY TO io.NavInputs[]. This is going to be obsoleted in the future. Please call io functions instead! - - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets - - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing, - with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. - - Mouse: - - PS4/PS5 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. - - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. - - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. - Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. - When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. - When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. - (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse moving back and forth!) - (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want - to set a boolean to ignore your other external mouse positions until the external source is moved again.) - - - API BREAKING CHANGES - ==================== - - Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. - Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. - When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. - You can read releases logs https://github.com/ocornut/imgui/releases for more details. - - - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete). - - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary. - - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO. - - 2022/01/20 (1.87) - inputs: reworded gamepad IO. - - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values. - - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used). - - 2022/01/17 (1.87) - inputs: reworked mouse IO. - - Backend writing to io.MousePos -> backend should call io.AddMousePosEvent() - - Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent() - - Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent() - - Backend writing to io.MouseHoveredViewport -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only] - note: for all calls to IO new functions, the Dear ImGui context should be bound/current. - read https://github.com/ocornut/imgui/issues/4921 for details. - - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details. - - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX) - - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) - - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes). - - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiKey_ModXXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiKey_ModXXX values.* - - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert. - - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper. - - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. - - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. - - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019) - - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen() - - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x - - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing()); - - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect - - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex - - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings - - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function. - - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. - - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): - - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() - - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder - - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). - - if you are using official backends from the source tree: you have nothing to do. - - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). - - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. - - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft - - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight - - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. - flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. - breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": - - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) - - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) - - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) - - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. - this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. - the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. - legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). - - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): - - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() - - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. - - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. - - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. - - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. - - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). - - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). - - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). - - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. - - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. - - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. - - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): - - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). - - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg - - ImGuiInputTextCallback -> use ImGuiTextEditCallback - - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData - - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). - - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! - - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. - - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures - - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. - - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): - - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend - - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) - - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) - - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT - - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT - - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): - - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. - - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. - - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). - - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). - - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. - - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. - - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. - - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! - - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). - replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). - worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: - - if you omitted the 'power' parameter (likely!), you are not affected. - - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. - - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. - see https://github.com/ocornut/imgui/issues/3361 for all details. - kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. - for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. - - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. - - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. - - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] - - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. - - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). - - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. - - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. - - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. - - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): - - ShowTestWindow() -> use ShowDemoWindow() - - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) - - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) - - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) - - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() - - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg - - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding - - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap - - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS - - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. - - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). - - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. - - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. - - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. - - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): - - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed - - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) - - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() - - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) - - ImFont::Glyph -> use ImFontGlyph - - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. - if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. - The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). - If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. - - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). - - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). - - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. - - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have - overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. - This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. - Please reach out if you are affected. - - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). - - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). - - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. - - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). - - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). - - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). - - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! - - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). - - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! - - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). - - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. - - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. - - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. - - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). - - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. - If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. - - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) - - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. - NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. - Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. - - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). - - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). - - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). - - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. - - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. - - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. - - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). - - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). - old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. - when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. - in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. - - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. - - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. - - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. - If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. - To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. - If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. - - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", - consistent with other functions. Kept redirection functions (will obsolete). - - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. - - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). - - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. - - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. - - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. - - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. - - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. - - 2018/02/07 (1.60) - reorganized context handling to be more explicit, - - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. - - removed Shutdown() function, as DestroyContext() serve this purpose. - - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. - - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. - - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. - - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. - - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). - - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). - - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. - - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. - - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). - - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags - - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. - - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. - - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). - - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). - - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). - - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). - - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). - - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. - - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. - Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. - - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. - - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. - - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. - - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); - - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. - - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. - - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. - removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. - IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) - IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) - IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] - - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! - - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). - - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). - - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). - - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". - - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! - - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). - - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). - - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. - - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. - - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. - - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. - - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). - - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). - - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). - - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. - - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. - - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' - - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse - - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. - - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. - - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). - - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. - - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. - - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. - - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. - If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. - This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: - ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } - If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. - - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). - - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. - - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). - - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. - - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). - - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) - - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). - - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. - - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. - - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. - - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. - - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. - GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. - GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! - - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize - - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. - - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason - - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. - you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. - - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. - this necessary change will break your rendering function! the fix should be very easy. sorry for that :( - - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. - - the signature of the io.RenderDrawListsFn handler has changed! - old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) - new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). - parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' - ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. - ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. - - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. - - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! - - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! - - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. - - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). - - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. - - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence - - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! - - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). - - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). - - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. - - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. - - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). - - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. - - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API - - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. - - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. - - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. - - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing - - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50. - - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing) - - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50. - - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once. - - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now. - - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior - - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing() - - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused) - - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions. - - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader. - - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels. - - old: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..]; - - new: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier); - you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation. - - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID() - - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix) - - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets - - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver) - - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph) - - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility - - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered() - - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly) - - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity) - - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale() - - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn - - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically) - - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite - - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes - - - FREQUENTLY ASKED QUESTIONS (FAQ) - ================================ - - Read all answers online: - https://www.dearimgui.org/faq or https://github.com/ocornut/imgui/blob/master/docs/FAQ.md (same url) - Read all answers locally (with a text editor or ideally a Markdown viewer): - docs/FAQ.md - Some answers are copied down here to facilitate searching in code. - - Q&A: Basics - =========== - - Q: Where is the documentation? - A: This library is poorly documented at the moment and expects the user to be acquainted with C/C++. - - Run the examples/ and explore them. - - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. - - The demo covers most features of Dear ImGui, so you can read the code and see its output. - - See documentation and comments at the top of imgui.cpp + effectively imgui.h. - - Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the - examples/ folder to explain how to integrate Dear ImGui with your own engine/application. - - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links. - - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful. - - Your programming IDE is your friend, find the type or function declaration to find comments - associated with it. - - Q: What is this library called? - Q: Which version should I get? - >> This library is called "Dear ImGui", please don't call it "ImGui" :) - >> See https://www.dearimgui.org/faq for details. - - Q&A: Integration - ================ - - Q: How to get started? - A: Read 'PROGRAMMER GUIDE' above.

Visuals are ideal as they inspire other programmers. - But even without visuals, disclosing your use of dear imgui helps the library grow credibility, and help other teams and programmers with taking decisions. - - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on GitHub or privately). - -*/ - -//------------------------------------------------------------------------- -// [SECTION] INCLUDES -//------------------------------------------------------------------------- - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#ifndef IMGUI_DISABLE - -#ifndef IMGUI_DEFINE_MATH_OPERATORS -#define IMGUI_DEFINE_MATH_OPERATORS -#endif - - -// System includes -#include // toupper -#include // vsnprintf, sscanf, printf -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include // intptr_t -#else -#include // intptr_t -#endif - -// [Windows] On non-Visual Studio compilers, we default to IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS unless explicitly enabled -#if defined(_WIN32) && !defined(_MSC_VER) && !defined(IMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS) && !defined(IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS) -#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS -#endif - -// [Windows] OS specific includes (optional) -#if defined(_WIN32) && defined(IMGUI_DISABLE_DEFAULT_FILE_FUNCTIONS) && defined(IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS) && defined(IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS) && !defined(IMGUI_DISABLE_WIN32_FUNCTIONS) -#define IMGUI_DISABLE_WIN32_FUNCTIONS -#endif -#if defined(_WIN32) && !defined(IMGUI_DISABLE_WIN32_FUNCTIONS) -#ifndef WIN32_LEAN_AND_MEAN -#define WIN32_LEAN_AND_MEAN -#endif -#ifndef NOMINMAX -#define NOMINMAX -#endif -#ifndef __MINGW32__ -#include // _wfopen, OpenClipboard -#else -#include -#endif -#if defined(WINAPI_FAMILY) && (WINAPI_FAMILY == WINAPI_FAMILY_APP) // UWP doesn't have all Win32 functions -#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS -#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS -#endif -#endif - -// [Apple] OS specific includes -#if defined(__APPLE__) -#include -#endif - -// Visual Studio warnings -#ifdef _MSC_VER -#pragma warning (disable: 4127) // condition expression is constant -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen -#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later -#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types -#endif -#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.

The default (0) matches sokoL_gfx.h's - default pass. - - sg_pixel_format depth_format - The depth-buffer pixel format of the render pass where - the UI will be rendered. The default (0) matches - sokol_gfx.h's default pass depth format. - - int sample_count - The MSAA sample-count of the render pass where the UI - will be rendered. The default (0) matches sokol_gfx.h's - default pass sample count. - - const char* ini_filename - Sets this path as ImGui::GetIO().IniFilename where ImGui will store - and load UI persistency data. By default this is 0, so that Dear ImGui - will not preserve state between sessions (and also won't do - any filesystem calls). Also see the ImGui functions: - - LoadIniSettingsFromMemory() - - SaveIniSettingsFromMemory() - These functions give you explicit control over loading and saving - UI state while using your own filesystem wrapper functions (in this - case keep simgui_desc.ini_filename zero) - - bool no_default_font - Set this to true if you don't want to use ImGui's default - font. In this case you need to initialize the font - yourself after simgui_setup() is called. - - bool disable_paste_override - If set to true, sokol_imgui.h will not 'emulate' a Dear Imgui - clipboard paste action on SAPP_EVENTTYPE_CLIPBOARD_PASTED event. - This is mainly a hack/workaround to allow external workarounds - for making copy/paste work on the web platform. In general, - copy/paste support isn't properly fleshed out in sokol_imgui.h yet. - - --- At the start of a frame, call: - - simgui_new_frame(&(simgui_frame_desc_t){.width = ..., .height = ..., .delta_time = ..., .dpi_scale = ...}); - - 'width' and 'height' are the dimensions of the rendering surface, - passed to ImGui::GetIO().DisplaySize. - - 'delta_time' is the frame duration passed to ImGui::GetIO().DeltaTime. - - 'dpi_scale' is the current DPI scale factor, if this is left zero-initialized, - 1.0f will be used instead. Typical values for dpi_scale are >= 1.0f. - - For example, if you're using sokol_app.h and render to the default framebuffer: - - simgui_new_frame(&(simgui_frame_desc_t){ - .width = sapp_width(), - .height = sapp_height(), - .delta_time = sapp_frame_duration(), - .dpi_scale = sapp_dpi_scale() - }); - - --- at the end of the frame, before the sg_end_pass() where you - want to render the UI, call: - - simgui_render() - - This will first call ImGui::Render(), and then render ImGui's draw list - through sokol_gfx.h - - --- if you're using sokol_app.h, from inside the sokol_app.h event callback, - call: - - bool simgui_handle_event(const sapp_event* ev); - - The return value is the value of ImGui::GetIO().WantCaptureKeyboard, - if this is true, you might want to skip keyboard input handling - in your own event handler. - - If you want to use the ImGui functions for checking if a key is pressed - (e.g. ImGui::IsKeyPressed()) the following helper function to map - an sapp_keycode to an ImGuiKey value may be useful: - - int simgui_map_keycode(sapp_keycode c); - - Note that simgui_map_keycode() can be called outside simgui_setup()/simgui_shutdown(). - - --- finally, on application shutdown, call - - simgui_shutdown() - - - MEMORY ALLOCATION OVERRIDE - ========================== - You can override the memory allocation functions at initialization time - like this: + On Windows, SOKOL_DLL will define SOKOL_GLUE_API_DECL as __declspec(dllexport) + or __declspec(dllimport) as needed. - void* my_alloc(size_t size, void* user_data) { - return malloc(size); - } + OVERVIEW + ======== + The sokol core headers should not depend on each other, but sometimes + it's useful to have a set of helper functions as "glue" between + two or more sokol headers. - void my_free(void* ptr, void* user_data) { - free(ptr); - } + This is what sokol_glue.h is for. Simply include the header after other + sokol headers (both for the implementation and declaration), and + depending on what headers have been included before, sokol_glue.h + will make available "glue functions". - ... - simgui_setup(&(simgui_desc_t){ - // ... - .allocator = { - .alloc = my_alloc, - .free = my_free, - .user_data = ...; - } - }); - ... + PROVIDED FUNCTIONS + ================== - If no overrides are provided, malloc and free will be used. + - if sokol_app.h and sokol_gfx.h is included: - This only affects memory allocation calls done by sokol_imgui.h - itself though, not any allocations in Dear ImGui. + sg_context_desc sapp_sgcontext(void): + Returns an initialized sg_context_desc function initialized + by calling sokol_app.h functions.

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHARCOUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, +// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN +// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, +// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the +// API below. The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to . I.e. if it returns x0,y0,x1,y1, +// then the character should be displayed in the rectangle from +// to = 32 && *text < 128) { + stbtt_aligned_quad q; + stbtt_GetBakedQuad(cdata, 512,512, *text-32, &x,&y,&q,1);//1=opengl & d3d10+,0=d3d9 + glTexCoord2f(q.s0,q.t0); glVertex2f(q.x0,q.y0); + glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y0); + glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y1); + glTexCoord2f(q.s0,q.t1); glVertex2f(q.x0,q.y1); + } + ++text; + } + glEnd(); +} +#endif +// +// +////////////////////////////////////////////////////////////////////////////// +// +// Complete program (this compiles): get a single bitmap, print as ASCII art +// +#if 0 +#include +#define STB_TRUETYPE_IMPLEMENTATION // force following include to generate implementation +#include "stb_truetype.h" + +char ttf_buffer[1<<25]; + +int main(int argc, char **argv) +{ + stbtt_fontinfo font; + unsigned char *bitmap; + int w,h,i,j,c = (argc > 1 ? atoi(argv[1]) : 'a'), s = (argc > 2 ? atoi(argv[2]) : 20); + + fread(ttf_buffer, 1, 1<<25, fopen(argc > 3 ? argv[3] : "c:/windows/fonts/arialbd.ttf", "rb")); + + stbtt_InitFont(&font, ttf_buffer, stbtt_GetFontOffsetForIndex(ttf_buffer,0)); + bitmap = stbtt_GetCodepointBitmap(&font, 0,stbtt_ScaleForPixelHeight(&font, s), c, &w, &h, 0,0); + + for (j=0; j < h; ++j) { + for (i=0; i < w; ++i) + putchar(" .:ioVM@"[bitmap[j*w+i]>>5]); + putchar('\n'); + } + return 0; +} +#endif +// +// Output: +// +// .ii. +// @@@@@@. +// V@Mio@@o +// :i.

Not recommended unless table is last item in parent window. +// - outer_size.y > 0.0f -> Set Exact height.

Only available when ScrollX/ScrollY are disabled and Stretch columns are not used. +// - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible. +// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height. +// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not easily noticeable) +//----------------------------------------------------------------------------- +// About 'inner_width': +// With ScrollX disabled: +// - inner_width -> *ignored* +// With ScrollX enabled: +// - inner_width < 0.0f -> *illegal* fit in known width (right align from outer_size.x) <-- weird +// - inner_width = 0.0f -> fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns. +// - inner_width > 0.0f -> override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space! +//----------------------------------------------------------------------------- +// Details: +// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept +// of "available space" doesn't make sense. +// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding +// of what the value does. +//----------------------------------------------------------------------------- + +//----------------------------------------------------------------------------- +// COLUMNS SIZING POLICIES +//----------------------------------------------------------------------------- +// About overriding column sizing policy and width/weight with TableSetupColumn(): +// We use a default parameter of 'init_width_or_weight == -1'. +// - with ImGuiTableColumnFlags_WidthFixed, init_width <= 0 (default) --> width is automatic +// - with ImGuiTableColumnFlags_WidthFixed, init_width > 0 (explicit) --> width is custom +// - with ImGuiTableColumnFlags_WidthStretch, init_weight <= 0 (default) --> weight is 1.0f +// - with ImGuiTableColumnFlags_WidthStretch, init_weight > 0 (explicit) --> weight is custom +// Widths are specified _without_ CellPadding.

Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know +// it is not going to contribute to row height. +// In many situations, you may skip submitting contents for every column but one (e.g. the first one). +// - Case A: column is not hidden by user, and at least partially in sight (most common case). +// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output. +// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.). +// +// [A] [B] [C] +// TableNextColumn(): true false false -> [userland] when TableNextColumn() / TableSetColumnIndex() return false, user can skip submitting items but only if the column doesn't contribute to row height. +// SkipItems: false false true -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output. +// ClipRect: normal zero-width zero-width -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way. +// ImDrawList output: normal dummy dummy -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway). +// +// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row. +// However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer. +//----------------------------------------------------------------------------- +// About clipping/culling of whole Tables: +// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false. +//----------------------------------------------------------------------------- + +//----------------------------------------------------------------------------- +// [SECTION] Header mess +//----------------------------------------------------------------------------- + +#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) +#define _CRT_SECURE_NO_WARNINGS +#endif + +#include "imgui.h" +#ifndef IMGUI_DISABLE + +#ifndef IMGUI_DEFINE_MATH_OPERATORS +#define IMGUI_DEFINE_MATH_OPERATORS +#endif + + +// System includes +#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier +#include // intptr_t +#else +#include // intptr_t +#endif + +// Visual Studio warnings +#ifdef _MSC_VER +#pragma warning (disable: 4127) // condition expression is constant +#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen +#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later +#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types +#endif +#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

A static variable persists across calls, +// so it is essentially like a global variable but declared inside the scope of the function. We do this as a way to +// gather code and data in the same place, to make the demo source code faster to read, faster to write, and smaller +// in size. It also happens to be a convenient way of storing simple UI related information as long as your function +// doesn't need to be reentrant or used in multiple threads. This might be a pattern you will want to use in your code, +// but most of the real data you would be editing is likely going to be stored outside your functions. + +// The Demo code in this file is designed to be easy to copy-and-paste into your application! +// Because of this: +// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace. +// - We try to declare static variables in the local scope, as close as possible to the code using them. +// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API. +// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided +// by imgui_internal.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional +// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h. +// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp. + +// Navigating this file: +// - In Visual Studio IDE: CTRL+comma ("Edit.GoToAll") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot. +// - With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments. + +/* + +Index of this file: + +// [SECTION] Forward Declarations +// [SECTION] Helpers +// [SECTION] Demo Window / ShowDemoWindow() +// - ShowDemoWindow() +// - sub section: ShowDemoWindowWidgets() +// - sub section: ShowDemoWindowLayout() +// - sub section: ShowDemoWindowPopups() +// - sub section: ShowDemoWindowTables() +// - sub section: ShowDemoWindowInputs() +// [SECTION] About Window / ShowAboutWindow() +// [SECTION] Style Editor / ShowStyleEditor() +// [SECTION] User Guide / ShowUserGuide() +// [SECTION] Example App: Main Menu Bar / ShowExampleAppMainMenuBar() +// [SECTION] Example App: Debug Console / ShowExampleAppConsole() +// [SECTION] Example App: Debug Log / ShowExampleAppLog() +// [SECTION] Example App: Simple Layout / ShowExampleAppLayout() +// [SECTION] Example App: Property Editor / ShowExampleAppPropertyEditor() +// [SECTION] Example App: Long Text / ShowExampleAppLongText() +// [SECTION] Example App: Auto Resize / ShowExampleAppAutoResize() +// [SECTION] Example App: Constrained Resize / ShowExampleAppConstrainedResize() +// [SECTION] Example App: Simple overlay / ShowExampleAppSimpleOverlay() +// [SECTION] Example App: Fullscreen window / ShowExampleAppFullscreen() +// [SECTION] Example App: Manipulating window titles / ShowExampleAppWindowTitles() +// [SECTION] Example App: Custom Rendering using ImDrawList API / ShowExampleAppCustomRendering() +// [SECTION] Example App: Documents Handling / ShowExampleAppDocuments() + +*/ + +#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) +#define _CRT_SECURE_NO_WARNINGS +#endif + +#include "imgui.h" +#ifndef IMGUI_DISABLE + +// System includes +#include // toupper +#include // INT_MIN, INT_MAX +#include // sqrtf, powf, cosf, sinf, floorf, ceilf +#include // vsnprintf, sscanf, printf +#include // NULL, malloc, free, atoi +#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier +#include // intptr_t +#else +#include // intptr_t +#endif + +// Visual Studio warnings +#ifdef _MSC_VER +#pragma warning (disable: 4127) // condition expression is constant +#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen +#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to an 8 byte value.

Download controller mapping PNG/PSD at http://dearimgui.org/controls_sheets + + + PROGRAMMER GUIDE + ================ + + READ FIRST + ---------- + - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki) + - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction or + destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. + - Try to keep your copy of Dear ImGui reasonably up to date. + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. + - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). + The sub-folders in examples/ contain examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into screen + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Build and load the texture atlas into a texture + // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) + int width, height; + unsigned char* pixels = NULL; + io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); + + // At this point you've got the texture data and you need to upload that to your graphic system: + // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. + // This will be passed back to your via the renderer.

For more advanced uses, you may want to read from: + - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. + - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). + - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. + Please reach out if you think the game vs navigation input sharing could be improved. + - Gamepad: + - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys. + For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly. + Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). + - BEFORE 1.87, BACKENDS USED TO WRITE TO io.NavInputs[]. This is now obsolete. Please call io functions instead! + - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets + - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing, + with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. + - Mouse: + - PS4/PS5 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. + Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse moving back and forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + API BREAKING CHANGES + ==================== + + Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. + Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. + When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. + You can read releases logs https://github.com/ocornut/imgui/releases for more details. + + - 2022/10/26 (1.89) - commented out redirecting OpenPopupContextItem() which was briefly the name of OpenPopupOnItemClick() from 1.77 to 1.79. + - 2022/10/12 (1.89) - removed runtime patching of invalid "%f"/"%0.f" format strings for DragInt()/SliderInt(). This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details. + - 2022/09/26 (1.89) - renamed and merged keyboard modifiers key enums and flags into a same set. Kept inline redirection enums (will obsolete). + - ImGuiKey_ModCtrl and ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl + - ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift + - ImGuiKey_ModAlt and ImGuiModFlags_Alt -> ImGuiMod_Alt + - ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super + the ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends. + the ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api only by third-party extensions. + exceptionally commenting out the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion and because they were not meant to be used anyway. + - 2022/09/12 (1.89) - removed the bizarre legacy default argument for 'TreePush(const void* ptr = NULL)', always pass a pointer value explicitly. NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr); + - 2022/09/05 (1.89) - commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.78 (June 2020): + - DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f. + - SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f. + - BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags) + - 2022/09/02 (1.89) - obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries. + this relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item. + - previously this would make the window content size ~200x200: + Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End(); + - instead, please submit an item: + Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End(); + - alternative: + Begin(...) + Dummy(ImVec2(200,200)) + End(); + - content size is now only extended when submitting an item! + - with '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert. + - without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it. + - 2022/08/03 (1.89) - changed signature of ImageButton() function. Kept redirection function (will obsolete). + - added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter. + - old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1)); + - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values. + - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer. + - new signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1)); + - requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier. + - always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this. + - 2022/07/08 (1.89) - inputs: removed io.NavInputs[] and ImGuiNavInput enum (following 1.87 changes). + - Official backends from 1.87+ -> no issue. + - Official backends from 1.60 to 1.86 -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating! + - Custom backends not writing to io.NavInputs[] -> no issue. + - Custom backends writing to io.NavInputs[] -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing! + - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[]. + - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete). + - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary. + - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO. + - 2022/01/20 (1.87) - inputs: reworded gamepad IO. + - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values. + - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used). + - 2022/01/17 (1.87) - inputs: reworked mouse IO. + - Backend writing to io.MousePos -> backend should call io.AddMousePosEvent() + - Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent() + - Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent() + - Backend writing to io.MouseHoveredViewport -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only] + note: for all calls to IO new functions, the Dear ImGui context should be bound/current. + read https://github.com/ocornut/imgui/issues/4921 for details. + - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details. + - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX) + - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) + - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes). + - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.* + - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert. + - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper. + - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. + - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. + - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019) + - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen() + - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x + - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing()); + - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect + - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex + - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings + - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function. + - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. + - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): + - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() + - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder + - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). + - if you are using official backends from the source tree: you have nothing to do. + - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). + - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. + - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft + - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight + - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. + flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. + breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": + - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) + - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) + - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) + - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. + this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. + the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. + legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). + - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): + - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() + - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. + - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. + - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. + - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). + - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. + - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing + - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused().

The default (0) matches sokoL_gfx.h's + default pass. + + sg_pixel_format depth_format + The depth-buffer pixel format of the render pass where + the UI will be rendered. The default (0) matches + sokol_gfx.h's default pass depth format. + + int sample_count + The MSAA sample-count of the render pass where the UI + will be rendered. The default (0) matches sokol_gfx.h's + default pass sample count. + + const char* ini_filename + Sets this path as ImGui::GetIO().IniFilename where ImGui will store + and load UI persistency data. By default this is 0, so that Dear ImGui + will not preserve state between sessions (and also won't do + any filesystem calls). Also see the ImGui functions: + - LoadIniSettingsFromMemory() + - SaveIniSettingsFromMemory() + These functions give you explicit control over loading and saving + UI state while using your own filesystem wrapper functions (in this + case keep simgui_desc.ini_filename zero) + + bool no_default_font + Set this to true if you don't want to use ImGui's default + font. In this case you need to initialize the font + yourself after simgui_setup() is called. + + bool disable_paste_override + If set to true, sokol_imgui.h will not 'emulate' a Dear Imgui + clipboard paste action on SAPP_EVENTTYPE_CLIPBOARD_PASTED event. + This is mainly a hack/workaround to allow external workarounds + for making copy/paste work on the web platform. In general, + copy/paste support isn't properly fleshed out in sokol_imgui.h yet. + + bool disable_set_mouse_cursor + If true, sokol_imgui.h will not control the mouse cursor type + by calling sapp_set_mouse_cursor(). + + bool disable_windows_resize_from_edges + If true, windows can only be resized from the bottom right corner. + The default is false, meaning windows can be resized from edges. + + bool write_alpha_channel + Set this to true if you want alpha values written to the + framebuffer. By default this behavior is disabled to prevent + undesired behavior on platforms like the web where the canvas is + always alpha-blended with the background. + + simgui_allocator_t allocator + Used to override memory allocation functions.

Typical values for dpi_scale are >= 1.0f. + + For example, if you're using sokol_app.h and render to the default framebuffer: + + simgui_new_frame(&(simgui_frame_desc_t){ + .width = sapp_width(), + .height = sapp_height(), + .delta_time = sapp_frame_duration(), + .dpi_scale = sapp_dpi_scale() + }); + + --- at the end of the frame, before the sg_end_pass() where you + want to render the UI, call: + + simgui_render() + + This will first call ImGui::Render(), and then render ImGui's draw list + through sokol_gfx.h + + --- if you're using sokol_app.h, from inside the sokol_app.h event callback, + call: + + bool simgui_handle_event(const sapp_event* ev); + + The return value is the value of ImGui::GetIO().WantCaptureKeyboard, + if this is true, you might want to skip keyboard input handling + in your own event handler. + + If you want to use the ImGui functions for checking if a key is pressed + (e.g. ImGui::IsKeyPressed()) the following helper function to map + an sapp_keycode to an ImGuiKey value may be useful: + + int simgui_map_keycode(sapp_keycode c); + + Note that simgui_map_keycode() can be called outside simgui_setup()/simgui_shutdown(). + + --- finally, on application shutdown, call + + simgui_shutdown() + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + simgui_setup(&(simgui_desc_t){ + // ... + .allocator = { + .alloc = my_alloc, + .free = my_free, + .user_data = ...; + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_imgui.h + itself though, not any allocations in Dear ImGui. + + + LICENSE + ======= + + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

In this mode, it declares a -// single public symbol, STB_TexteditState, which encapsulates the current -// state of a text widget (except for the string, which you will store -// separately). -// -// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a -// primitive type that defines a single character (e.g. char, wchar_t, etc). -// -// To save space or increase undo-ability, you can optionally define the -// following things that are used by the undo system: -// -// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// If you don't define these, they are set to permissive types and -// moderate sizes. The undo system does no memory allocations, so -// it grows STB_TexteditState by the worst-case storage which is (in bytes): -// -// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT -// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHARCOUNT -// -// -// Implementation mode: -// -// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it -// will compile the implementation of the text edit widget, depending -// on a large number of symbols which must be defined before the include. -// -// The implementation is defined only as static functions. You will then -// need to provide your own APIs in the same file which will access the -// static functions. -// -// The basic concept is that you provide a "string" object which -// behaves like an array of characters. stb_textedit uses indices to -// refer to positions in the string, implicitly representing positions -// in the displayed textedit. This is true for both plain text and -// rich text; even with rich text stb_truetype interacts with your -// code as if there was an array of all the displayed characters. -// -// Symbols that must be the same in header-file and implementation mode: -// -// STB_TEXTEDIT_CHARTYPE the character type -// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// Symbols you must define for implementation mode: -// -// STB_TEXTEDIT_STRING the type of object representing a string being edited, -// typically this is a wrapper object with other data you need -// -// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) -// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters -// starting from character #n (see discussion below) -// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character -// to the xpos of the i+1'th char for a line of characters -// starting at character #n (i.e. accounts for kerning -// with previous char) -// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character -// (return type is int, -1 means not valid to insert) -// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based -// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize -// as manually wordwrapping for end-of-line positioning -// -// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i -// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) -// -// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key -// -// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left -// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right -// STB_TEXTEDIT_K_UP keyboard input to move cursor up -// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down -// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page -// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page -// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME -// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END -// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME -// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END -// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor -// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor -// STB_TEXTEDIT_K_UNDO keyboard input to perform undo -// STB_TEXTEDIT_K_REDO keyboard input to perform redo -// -// Optional: -// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode -// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), -// required for default WORDLEFT/WORDRIGHT handlers -// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to -// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to -// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT -// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT -// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line -// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line -// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text -// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text -// -// Keyboard input must be encoded as a single integer value; e.g. a character code -// and some bitflags that represent shift states. to simplify the interface, SHIFT must -// be a bitflag, so we can test the shifted state of cursor movements to allow selection, -// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. -// -// You can encode other things, such as CONTROL or ALT, in additional bits, and -// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, -// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN -// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, -// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the -// API below. The control keys will only match WM_KEYDOWN events because of the -// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN -// bit so it only decodes WM_CHAR events. -// -// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed -// row of characters assuming they start on the i'th character--the width and -// the height and the number of characters consumed. This allows this library -// to traverse the entire layout incrementally. You need to compute word-wrapping -// here. -// -// Each textfield keeps its own insert mode state, which is not how normal -// applications work. To keep an app-wide insert mode, update/copy the -// "insert_mode" field of STB_TexteditState before/after calling API functions. -// -// API -// -// void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line) -// -// void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y) -// int stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state) -// int stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len) -// void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key) -// -// Each of these functions potentially updates the string and updates the -// state. -// -// initialize_state: -// set the textedit state to a known good default state when initially -// constructing the textedit. -// -// click: -// call this with the mouse x,y on a mouse down; it will update the cursor -// and reset the selection start/end to the cursor point. the x,y must -// be relative to the text widget, with (0,0) being the top left. -// -// drag: -// call this with the mouse x,y on a mouse drag/up; it will update the -// cursor and the selection end point -// -// cut: -// call this to delete the current selection; returns true if there was -// one. you should FIRST copy the current selection to the system paste buffer. -// (To copy, just copy the current selection out of the string yourself.) -// -// paste: -// call this to paste text at the current cursor point or over the current -// selection if there is one. -// -// key: -// call this for keyboard inputs sent to the textfield. you can use it -// for "key down" events or for "translated" key events. if you need to -// do both (as in Win32), or distinguish Unicode characters from control -// inputs, set a high bit to distinguish the two; then you can define the -// various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit -// set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is -// clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to -// anything other type you wante before including. -// -// -// When rendering, you can read the cursor position and selection state from -// the STB_TexteditState. -// -// -// Notes: -// -// This is designed to be usable in IMGUI, so it allows for the possibility of -// running in an IMGUI that has NOT cached the multi-line layout. For this -// reason, it provides an interface that is compatible with computing the -// layout incrementally--we try to make sure we make as few passes through -// as possible. (For example, to locate the mouse pointer in the text, we -// could define functions that return the X and Y positions of characters -// and binary search Y and then X, but if we're doing dynamic layout this -// will run the layout algorithm many times, so instead we manually search -// forward in one pass. Similar logic applies to e.g. up-arrow and -// down-arrow movement.) -// -// If it's run in a widget that *has* cached the layout, then this is less -// efficient, but it's not horrible on modern computers. But you wouldn't -// want to edit million-line files with it. - - -//////////////////////////////////////////////////////////////////////////// -//////////////////////////////////////////////////////////////////////////// -//// -//// Header-file mode -//// -//// - -#ifndef INCLUDE_STB_TEXTEDIT_H -#define INCLUDE_STB_TEXTEDIT_H - -//////////////////////////////////////////////////////////////////////// -// -// STB_TexteditState -// -// Definition of STB_TexteditState which you should store -// per-textfield;

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHARCOUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT.

The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally. You need to compute word-wrapping +// here. +// +// Each textfield keeps its own insert mode state, which is not how normal +// applications work.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers. But you wouldn't +// want to edit million-line files with it. + + +//////////////////////////////////////////////////////////////////////////// +//////////////////////////////////////////////////////////////////////////// +//// +//// Header-file mode +//// +//// + +#ifndef INCLUDE_STB_TEXTEDIT_H +#define INCLUDE_STB_TEXTEDIT_H + +//////////////////////////////////////////////////////////////////////// +// +// STB_TexteditState +// +// Definition of STB_TexteditState which you should store +// per-textfield;

This - function is called very early, usually at the start of the - platform's entry function (e.g. main or WinMain). You should do as - little as possible here, since the rest of your code might be called - from another thread (this depends on the platform): - - sapp_desc sokol_main(int argc, char* argv[]) { - return (sapp_desc) { - .width = 640, - .height = 480, - .init_cb = my_init_func, - .frame_cb = my_frame_func, - .cleanup_cb = my_cleanup_func, - .event_cb = my_event_func, - ... - }; - } - - There are many more setup parameters, but these are the most important. - For a complete list search for the sapp_desc structure declaration - below. - - DO NOT call any sokol-app function from inside sokol_main(), since - sokol-app will not be initialized at this point. - - The .width and .height parameters are the preferred size of the 3D - rendering canvas. The actual size may differ from this depending on - platform and other circumstances. Also the canvas size may change at - any time (for instance when the user resizes the application window, - or rotates the mobile device). You can just keep .width and .height - zero-initialized to open a default-sized window (what "default-size" - exactly means is platform-specific, but usually it's a size that covers - most of, but not all, of the display). - - All provided function callbacks will be called from the same thread, - but this may be different from the thread where sokol_main() was called. - - .init_cb (void (*)(void)) - This function is called once after the application window, - 3D rendering context and swap chain have been created. The - function takes no arguments and has no return value. - .frame_cb (void (*)(void)) - This is the per-frame callback, which is usually called 60 - times per second. This is where your application would update - most of its state and perform all rendering. - .cleanup_cb (void (*)(void)) - The cleanup callback is called once right before the application - quits. - .event_cb (void (*)(const sapp_event* event)) - The event callback is mainly for input handling, but is also - used to communicate other types of events to the application. Keep the - event_cb struct member zero-initialized if your application doesn't require - event handling. - .fail_cb (void (*)(const char* msg)) - The fail callback is called when a fatal error is encountered - during start which doesn't allow the program to continue. - Providing a callback here gives you a chance to show an error message - to the user. The default behaviour is SOKOL_LOG(msg) - - As you can see, those 'standard callbacks' don't have a user_data - argument, so any data that needs to be preserved between callbacks - must live in global variables. If keeping state in global variables - is not an option, there's an alternative set of callbacks with - an additional user_data pointer argument: - - .user_data (void*) - The user-data argument for the callbacks below - .init_userdata_cb (void (*)(void* user_data)) - .frame_userdata_cb (void (*)(void* user_data)) - .cleanup_userdata_cb (void (*)(void* user_data)) - .event_userdata_cb (void(*)(const sapp_event* event, void* user_data)) - .fail_userdata_cb (void(*)(const char* msg, void* user_data)) - These are the user-data versions of the callback functions. You - can mix those with the standard callbacks that don't have the - user_data argument. - - The function sapp_userdata() can be used to query the user_data - pointer provided in the sapp_desc struct. - - You can also call sapp_query_desc() to get a copy of the - original sapp_desc structure. - - NOTE that there's also an alternative compile mode where sokol_app.h - doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY. - - --- Implement the initialization callback function (init_cb), this is called - once after the rendering surface, 3D API and swap chain have been - initialized by sokol_app. All sokol-app functions can be called - from inside the initialization callback, the most useful functions - at this point are: - - int sapp_width(void) - int sapp_height(void) - Returns the current width and height of the default framebuffer in pixels, - this may change from one frame to the next, and it may be different - from the initial size provided in the sapp_desc struct. - - float sapp_widthf(void) - float sapp_heightf(void) - These are alternatives to sapp_width() and sapp_height() which return - the default framebuffer size as float values instead of integer. This - may help to prevent casting back and forth between int and float - in more strongly typed languages than C and C++. - - double sapp_frame_duration(void) - Returns the frame duration in seconds averaged over a number of - frames to smooth out any jittering spikes. - - int sapp_color_format(void) - int sapp_depth_format(void) - The color and depth-stencil pixelformats of the default framebuffer, - as integer values which are compatible with sokol-gfx's - sg_pixel_format enum (so that they can be plugged directly in places - where sg_pixel_format is expected). Possible values are: - - 23 == SG_PIXELFORMAT_RGBA8 - 27 == SG_PIXELFORMAT_BGRA8 - 41 == SG_PIXELFORMAT_DEPTH - 42 == SG_PIXELFORMAT_DEPTH_STENCIL - - int sapp_sample_count(void) - Return the MSAA sample count of the default framebuffer. - - bool sapp_gles2(void) - Returns true if a GLES2 or WebGL context has been created. This - is useful when a GLES3/WebGL2 context was requested but is not - available so that sokol_app.h had to fallback to GLES2/WebGL. - - const void* sapp_metal_get_device(void) - const void* sapp_metal_get_renderpass_descriptor(void) - const void* sapp_metal_get_drawable(void) - If the Metal backend has been selected, these functions return pointers - to various Metal API objects required for rendering, otherwise - they return a null pointer. These void pointers are actually - Objective-C ids converted with a (ARC) __bridge cast so that - the ids can be tunnel through C code. Also note that the returned - pointers to the renderpass-descriptor and drawable may change from one - frame to the next, only the Metal device object is guaranteed to - stay the same. - - const void* sapp_macos_get_window(void) - On macOS, get the NSWindow object pointer, otherwise a null pointer. - Before being used as Objective-C object, the void* must be converted - back with a (ARC) __bridge cast. - - const void* sapp_ios_get_window(void) - On iOS, get the UIWindow object pointer, otherwise a null pointer. - Before being used as Objective-C object, the void* must be converted - back with a (ARC) __bridge cast. - - const void* sapp_win32_get_hwnd(void) - On Windows, get the window's HWND, otherwise a null pointer. The - HWND has been cast to a void pointer in order to be tunneled - through code which doesn't include Windows.h. - - const void* sapp_d3d11_get_device(void) - const void* sapp_d3d11_get_device_context(void) - const void* sapp_d3d11_get_render_target_view(void) - const void* sapp_d3d11_get_depth_stencil_view(void) - Similar to the sapp_metal_* functions, the sapp_d3d11_* functions - return pointers to D3D11 API objects required for rendering, - only if the D3D11 backend has been selected. Otherwise they - return a null pointer. Note that the returned pointers to the - render-target-view and depth-stencil-view may change from one - frame to the next! - - const void* sapp_wgpu_get_device(void) - const void* sapp_wgpu_get_render_view(void) - const void* sapp_wgpu_get_resolve_view(void) - const void* sapp_wgpu_get_depth_stencil_view(void) - These are the WebGPU-specific functions to get the WebGPU - objects and values required for rendering. If sokol_app.h - is not compiled with SOKOL_WGPU, these functions return null. - - const void* sapp_android_get_native_activity(void); - On Android, get the native activity ANativeActivity pointer, otherwise - a null pointer. - - --- Implement the frame-callback function, this function will be called - on the same thread as the init callback, but might be on a different - thread than the sokol_main() function. Note that the size of - the rendering framebuffer might have changed since the frame callback - was called last. Call the functions sapp_width() and sapp_height() - each frame to get the current size. - - --- Optionally implement the event-callback to handle input events. - sokol-app provides the following type of input events: - - a 'virtual key' was pressed down or released - - a single text character was entered (provided as UTF-32 code point) - - a mouse button was pressed down or released (left, right, middle) - - mouse-wheel or 2D scrolling events - - the mouse was moved - - the mouse has entered or left the application window boundaries - - low-level, portable multi-touch events (began, moved, ended, cancelled) - - the application window was resized, iconified or restored - - the application was suspended or restored (on mobile platforms) - - the user or application code has asked to quit the application - - a string was pasted to the system clipboard - - one or more files have been dropped onto the application window - - To explicitly 'consume' an event and prevent that the event is - forwarded for further handling to the operating system, call - sapp_consume_event() from inside the event handler (NOTE that - this behaviour is currently only implemented for some HTML5 - events, support for other platforms and event types will - be added as needed, please open a github ticket and/or provide - a PR if needed). - - NOTE: Do *not* call any 3D API rendering functions in the event - callback function, since the 3D API context may not be active when the - event callback is called (it may work on some platforms and 3D APIs, - but not others, and the exact behaviour may change between - sokol-app versions). - - --- Implement the cleanup-callback function, this is called once - after the user quits the application (see the section - "APPLICATION QUIT" for detailed information on quitting - behaviour, and how to intercept a pending quit - for instance to show a - "Really Quit?" dialog box). Note that the cleanup-callback isn't - guaranteed to be called on the web and mobile platforms. - - MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE) - ================================================ - In normal mouse mode, no mouse movement events are reported when the - mouse leaves the windows client area or hits the screen border (whether - it's one or the other depends on the platform), and the mouse move events - (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in - framebuffer pixels in the sapp_event items mouse_x and mouse_y, and - relative movement in framebuffer pixels in the sapp_event items mouse_dx - and mouse_dy. - - To get continuous mouse movement (also when the mouse leaves the window - client area or hits the screen border), activate mouse-lock mode - by calling: - - sapp_lock_mouse(true) - - When mouse lock is activated, the mouse pointer is hidden, the - reported absolute mouse position (sapp_event.mouse_x/y) appears - frozen, and the relative mouse movement in sapp_event.mouse_dx/dy - no longer has a direct relation to framebuffer pixels but instead - uses "raw mouse input" (what "raw mouse input" exactly means also - differs by platform). - - To deactivate mouse lock and return to normal mouse mode, call - - sapp_lock_mouse(false) - - And finally, to check if mouse lock is currently active, call - - if (sapp_mouse_locked()) { ... } - - On native platforms, the sapp_lock_mouse() and sapp_mouse_locked() - functions work as expected (mouse lock is activated or deactivated - immediately when sapp_lock_mouse() is called, and sapp_mouse_locked() - also immediately returns the new state after sapp_lock_mouse() - is called. - - On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave - differently, as dictated by the limitations of the HTML5 Pointer Lock API: - - - sapp_lock_mouse(true) can be called at any time, but it will - only take effect in a 'short-lived input event handler of a specific - type', meaning when one of the following events happens: - - SAPP_EVENTTYPE_MOUSE_DOWN - - SAPP_EVENTTYPE_MOUSE_UP - - SAPP_EVENTTYPE_MOUSE_SCROLL - - SAPP_EVENTTYPE_KEY_UP - - SAPP_EVENTTYPE_KEY_DOWN - - The mouse lock/unlock action on the web platform is asynchronous, - this means that sapp_mouse_locked() won't immediately return - the new status after calling sapp_lock_mouse(), instead the - reported status will only change when the pointer lock has actually - been activated or deactivated in the browser. - - On the web, mouse lock can be deactivated by the user at any time - by pressing the Esc key. When this happens, sokol_app.h behaves - the same as if sapp_lock_mouse(false) is called. - - For things like camera manipulation it's most straightforward to lock - and unlock the mouse right from the sokol_app.h event handler, for - instance the following code enters and leaves mouse lock when the - left mouse button is pressed and released, and then uses the relative - movement information to manipulate a camera (taken from the - cgltf-sapp.c sample in the sokol-samples repository - at https://github.com/floooh/sokol-samples): - - static void input(const sapp_event* ev) { - switch (ev->type) { - case SAPP_EVENTTYPE_MOUSE_DOWN: - if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { - sapp_lock_mouse(true); - } - break; - - case SAPP_EVENTTYPE_MOUSE_UP: - if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { - sapp_lock_mouse(false); - } - break; - - case SAPP_EVENTTYPE_MOUSE_MOVE: - if (sapp_mouse_locked()) { - cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f); - } - break; - - default: - break; - } - } - - CLIPBOARD SUPPORT - ================= - Applications can send and receive UTF-8 encoded text data from and to the - system clipboard. By default, clipboard support is disabled and - must be enabled at startup via the following sapp_desc struct - members: - - sapp_desc.enable_clipboard - set to true to enable clipboard support - sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes - - Enabling the clipboard will dynamically allocate a clipboard buffer - for UTF-8 encoded text data of the requested size in bytes, the default - size is 8 KBytes. Strings that don't fit into the clipboard buffer - (including the terminating zero) will be silently clipped, so it's - important that you provide a big enough clipboard size for your - use case. - - To send data to the clipboard, call sapp_set_clipboard_string() with - a pointer to an UTF-8 encoded, null-terminated C-string. - - NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be - called from inside a 'short-lived event handler', and there are a few - other HTML5-specific caveats to workaround. You'll basically have to - tinker until it works in all browsers :/ (maybe the situation will - improve when all browsers agree on and implement the new - HTML5 navigator.clipboard API). - - To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED - event in your event handler function, and then call sapp_get_clipboard_string() - to obtain the pasted UTF-8 encoded text. - - NOTE that behaviour of sapp_get_clipboard_string() is slightly different - depending on platform: - - - on the HTML5 platform, the internal clipboard buffer will only be updated - right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent, - and sapp_get_clipboard_string() will simply return the current content - of the clipboard buffer - - on 'native' platforms, the call to sapp_get_clipboard_string() will - update the internal clipboard buffer with the most recent data - from the system clipboard - - Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event, - and then call sapp_get_clipboard_string() right in the event handler. - - The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app - as follows: - - - on macOS: when the Cmd+V key is pressed down - - on HTML5: when the browser sends a 'paste' event to the global 'window' object - - on all other platforms: when the Ctrl+V key is pressed down - - DRAG AND DROP SUPPORT - ===================== - PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5 - and on the native desktop platforms (Win32, Linux and macOS) because - of security-related restrictions in the HTML5 drag'n'drop API. The - WASM/HTML5 specifics are described at the end of this documentation - section: - - Like clipboard support, drag'n'drop support must be explicitly enabled - at startup in the sapp_desc struct. - - sapp_desc sokol_main() { - return (sapp_desc) { - .enable_dragndrop = true, // default is false - ... - }; - } - - You can also adjust the maximum number of files that are accepted - in a drop operation, and the maximum path length in bytes if needed: - - sapp_desc sokol_main() { - return (sapp_desc) { - .enable_dragndrop = true, // default is false - .max_dropped_files = 8, // default is 1 - .max_dropped_file_path_length = 8192, // in bytes, default is 2048 - ... - }; - } - - When drag'n'drop is enabled, the event callback will be invoked with an - event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on - the application window. - - After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the - number of dropped files, and their absolute paths by calling separate - functions: - - void on_event(const sapp_event* ev) { - if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) { - - // the mouse position where the drop happened - float x = ev->mouse_x; - float y = ev->mouse_y; - - // get the number of files and their paths like this: - const int num_dropped_files = sapp_get_num_dropped_files(); - for (int i = 0; i < num_dropped_files; i++) { - const char* path = sapp_get_dropped_file_path(i); - ... - } - } - } - - The returned file paths are UTF-8 encoded strings. - - You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path() - anywhere, also outside the event handler callback, but be aware that the - file path strings will be overwritten with the next drop operation. - - In any case, sapp_get_dropped_file_path() will never return a null pointer, - instead an empty string "" will be returned if the drag'n'drop feature - hasn't been enabled, the last drop-operation failed, or the file path index - is out of range. - - Drag'n'drop caveats: - - - if more files are dropped in a single drop-action - than sapp_desc.max_dropped_files, the additional - files will be silently ignored - - if any of the file paths is longer than - sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8 - encoding) the entire drop operation will be silently ignored (this - needs some sort of error feedback in the future) - - no mouse positions are reported while the drag is in - process, this may change in the future - - Drag'n'drop on HTML5/WASM: - - The HTML5 drag'n'drop API doesn't return file paths, but instead - black-box 'file objects' which must be used to load the content - of dropped files. This is the reason why sokol_app.h adds two - HTML5-specific functions to the drag'n'drop API: - - uint32_t sapp_html5_get_dropped_file_size(int index) - Returns the size in bytes of a dropped file. - - void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request) - Asynchronously loads the content of a dropped file into a - provided memory buffer (which must be big enough to hold - the file content) - - To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED - event is received: - - sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){ - .dropped_file_index = 0, - .callback = fetch_cb - .buffer_ptr = buf, - .buffer_size = buf_size, - .user_data = ... - }); - - Make sure that the memory pointed to by 'buf' stays valid until the - callback function is called! - - As result of the asynchronous loading operation (no matter if succeeded or - failed) the 'fetch_cb' function will be called: - - void fetch_cb(const sapp_html5_fetch_response* response) { - // IMPORTANT: check if the loading operation actually succeeded: - if (response->succeeded) { - // the size of the loaded file: - const uint32_t num_bytes = response->fetched_size; - // and the pointer to the data (same as 'buf' in the fetch-call): - const void* ptr = response->buffer_ptr; - } - else { - // on error check the error code: - switch (response->error_code) { - case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL: - ... - break; - case SAPP_HTML5_FETCH_ERROR_OTHER: - ... - break; - } - } - } - - Check the droptest-sapp example for a real-world example which works - both on native platforms and the web: - - https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c - - HIGH-DPI RENDERING - ================== - You can set the sapp_desc.high_dpi flag during initialization to request - a full-resolution framebuffer on HighDPI displays. The default behaviour - is sapp_desc.high_dpi=false, this means that the application will - render to a lower-resolution framebuffer on HighDPI displays and the - rendered content will be upscaled by the window system composer. - - In a HighDPI scenario, you still request the same window size during - sokol_main(), but the framebuffer sizes returned by sapp_width() - and sapp_height() will be scaled up according to the DPI scaling - ratio. - - Note that on some platforms the DPI scaling factor may change at any - time (for instance when a window is moved from a high-dpi display - to a low-dpi display). - - To query the current DPI scaling factor, call the function: - - float sapp_dpi_scale(void); - - For instance on a Retina Mac, returning the following sapp_desc - struct from sokol_main(): - - sapp_desc sokol_main() { - return (sapp_desc) { - .width = 640, - .height = 480, - .high_dpi = true, - ... - }; - } - - ...the functions the functions sapp_width(), sapp_height() - and sapp_dpi_scale() will return the following values: - - sapp_width: 1280 - sapp_height: 960 - sapp_dpi_scale: 2.0 - - If the high_dpi flag is false, or you're not running on a Retina display, - the values would be: - - sapp_width: 640 - sapp_height: 480 - sapp_dpi_scale: 1.0 - - If the window is moved from the Retina display to a low-dpi external display, - the values would change as follows: - - sapp_width: 1280 => 640 - sapp_height: 960 => 480 - sapp_dpi_scale: 2.0 => 1.0 - - Currently there is no event associated with a DPI change, but an - SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the - framebuffer size changing. - - Per-monitor DPI is currently supported on macOS and Windows. - - APPLICATION QUIT - ================ - Without special quit handling, a sokol_app.h application will quit - 'gracefully' when the user clicks the window close-button unless a - platform's application model prevents this (e.g. on web or mobile). - 'Graceful exit' means that the application-provided cleanup callback will - be called before the application quits. - - On native desktop platforms sokol_app.h provides more control over the - application-quit-process. It's possible to initiate a 'programmatic quit' - from the application code, and a quit initiated by the application user can - be intercepted (for instance to show a custom dialog box). - - This 'programmatic quit protocol' is implemented through 3 functions - and 1 event: - - - sapp_quit(): This function simply quits the application without - giving the user a chance to intervene. Usually this might - be called when the user clicks the 'Ok' button in a 'Really Quit?' - dialog box - - sapp_request_quit(): Calling sapp_request_quit() will send the - event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler - callback, giving the user code a chance to intervene and cancel the - pending quit process (for instance to show a 'Really Quit?' dialog - box). If the event handler callback does nothing, the application - will be quit as usual. To prevent this, call the function - sapp_cancel_quit() from inside the event handler. - - sapp_cancel_quit(): Cancels a pending quit request, either initiated - by the user clicking the window close button, or programmatically - by calling sapp_request_quit(). The only place where calling this - function makes sense is from inside the event handler callback when - the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received. - - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user - clicks the window's close button or application code calls the - sapp_request_quit() function. The event handler callback code can handle - this event by calling sapp_cancel_quit() to cancel the quit. - If the event is ignored, the application will quit as usual. - - On the web platform, the quit behaviour differs from native platforms, - because of web-specific restrictions: - - A `programmatic quit` initiated by calling sapp_quit() or - sapp_request_quit() will work as described above: the cleanup callback is - called, platform-specific cleanup is performed (on the web - this means that JS event handlers are unregisters), and then - the request-animation-loop will be exited. However that's all. The - web page itself will continue to exist (e.g. it's not possible to - programmatically close the browser tab). - - On the web it's also not possible to run custom code when the user - closes a brower tab, so it's not possible to prevent this with a - fancy custom dialog box. - - Instead the standard "Leave Site?" dialog box can be activated (or - deactivated) with the following function: - - sapp_html5_ask_leave_site(bool ask); - - The initial state of the associated internal flag can be provided - at startup via sapp_desc.html5_ask_leave_site. - - This feature should only be used sparingly in critical situations - for - instance when the user would loose data - since popping up modal dialog - boxes is considered quite rude in the web world. Note that there's no way - to customize the content of this dialog box or run any code as a result - of the user's decision. Also note that the user must have interacted with - the site before the dialog box will appear. These are all security measures - to prevent fishing. - - The Dear ImGui HighDPI sample contains example code of how to - implement a 'Really Quit?' dialog box with Dear ImGui (native desktop - platforms only), and for showing the hardwired "Leave Site?" dialog box - when running on the web platform: - - https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html - - FULLSCREEN - ========== - If the sapp_desc.fullscreen flag is true, sokol-app will try to create - a fullscreen window on platforms with a 'proper' window system - (mobile devices will always use fullscreen). The implementation details - depend on the target platform, in general sokol-app will use a - 'soft approach' which doesn't interfere too much with the platform's - window system (for instance borderless fullscreen window instead of - a 'real' fullscreen mode). Such details might change over time - as sokol-app is adapted for different needs. - - The most important effect of fullscreen mode to keep in mind is that - the requested canvas width and height will be ignored for the initial - window size, calling sapp_width() and sapp_height() will instead return - the resolution of the fullscreen canvas (however the provided size - might still be used for the non-fullscreen window, in case the user can - switch back from fullscreen- to windowed-mode). - - To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen(). - - To check if the application window is currently in fullscreen mode, - call sapp_is_fullscreen(). - - WINDOW ICON SUPPORT - =================== - Some sokol_app.h backends allow to change the window icon programmatically: - - - on Win32: the small icon in the window's title bar, and the - bigger icon in the task bar - - on Linux: highly dependent on the used window manager, but usually - the window's title bar icon and/or the task bar icon - - on HTML5: the favicon shown in the page's browser tab - - NOTE that it is not possible to set the actual application icon which is - displayed by the operating system on the desktop or 'home screen'. Those - icons must be provided 'traditionally' through operating-system-specific - resources which are associated with the application (sokol_app.h might - later support setting the window icon from platform specific resource data - though). - - There are two ways to set the window icon: - - - at application start in the sokol_main() function by initializing - the sapp_desc.icon nested struct - - or later by calling the function sapp_set_icon() - - As a convenient shortcut, sokol_app.h comes with a builtin default-icon - (a rainbow-colored 'S', which at least looks a bit better than the Windows - default icon for applications), which can be activated like this: - - At startup in sokol_main(): - - sapp_desc sokol_main(...) { - return (sapp_desc){ - ... - icon.sokol_default = true - }; - } - - Or later by calling: - - sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true }); - - NOTE that a completely zero-initialized sapp_icon_desc struct will not - update the window icon in any way. This is an 'escape hatch' so that you - can handle the window icon update yourself (or if you do this already, - sokol_app.h won't get in your way, in this case just leave the - sapp_desc.icon struct zero-initialized). - - Providing your own icon images works exactly like in GLFW (down to the - data format): - - You provide one or more 'candidate images' in different sizes, and the - sokol_app.h platform backends pick the best match for the specific backend - and icon type. - - For each candidate image, you need to provide: - - - the width in pixels - - the height in pixels - - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844 - on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44) - - For instance, if you have 3 candidate images (small, medium, big) of - sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup - like this: - - // the actual pixel data (RGBA8, origin top-left) - const uint32_t small[16][16] = { ... }; - const uint32_t medium[32][32] = { ... }; - const uint32_t big[64][64] = { ... }; - - const sapp_icon_desc icon_desc = { - .images = { - { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) }, - { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) }, - // ...or without the SAPP_RANGE helper macro: - { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } } - } - }; - - An sapp_icon_desc struct initialized like this can then either be applied - at application start in sokol_main: - - sapp_desc sokol_main(...) { - return (sapp_desc){ - ... - icon = icon_desc - }; - } - - ...or later by calling sapp_set_icon(): - - sapp_set_icon(&icon_desc); - - Some window icon caveats: - - - once the window icon has been updated, there's no way to go back to - the platform's default icon, this is because some platforms (Linux - and HTML5) don't switch the icon visual back to the default even if - the custom icon is deleted or removed - - on HTML5, if the sokol_app.h icon doesn't show up in the browser - tab, check that there's no traditional favicon 'link' element - is defined in the page's index.html, sokol_app.h will only - append a new favicon link element, but not delete any manually - defined favicon in the page - - For an example and test of the window icon feature, check out the the - 'icon-sapp' sample on the sokol-samples git repository. - - ONSCREEN KEYBOARD - ================= - On some platforms which don't provide a physical keyboard, sokol-app - can display the platform's integrated onscreen keyboard for text - input. To request that the onscreen keyboard is shown, call - - sapp_show_keyboard(true); - - Likewise, to hide the keyboard call: - - sapp_show_keyboard(false); - - Note that on the web platform, the keyboard can only be shown from - inside an input handler. On such platforms, sapp_show_keyboard() - will only work as expected when it is called from inside the - sokol-app event callback function. When called from other places, - an internal flag will be set, and the onscreen keyboard will be - called at the next 'legal' opportunity (when the next input event - is handled). - - OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY) - ====================================================== - In its default configuration, sokol_app.h "hijacks" the platform's - standard main() function. This was done because different platforms - have different main functions which are not compatible with - C's main() (for instance WinMain on Windows has completely different - arguments). However, this "main hijacking" posed a problem for - usage scenarios like integrating sokol_app.h with other languages than - C or C++, so an alternative SOKOL_NO_ENTRY mode has been added - in which the user code provides the platform's main function: - - - define SOKOL_NO_ENTRY before including the sokol_app.h implementation - - do *not* provide a sokol_main() function - - instead provide the standard main() function of the platform - - from the main function, call the function ```sapp_run()``` which - takes a pointer to an ```sapp_desc``` structure. - - ```sapp_run()``` takes over control and calls the provided init-, frame-, - shutdown- and event-callbacks just like in the default model, it - will only return when the application quits (or not at all on some - platforms, like emscripten) - - NOTE: SOKOL_NO_ENTRY is currently not supported on Android. - - WINDOWS CONSOLE OUTPUT - ====================== - On Windows, regular windowed applications don't show any stdout/stderr text - output, which can be a bit of a hassle for printf() debugging or generally - logging text to the console. Also, console output by default uses a local - codepage setting and thus international UTF-8 encoded text is printed - as garbage. - - To help with these issues, sokol_app.h can be configured at startup - via the following Windows-specific sapp_desc flags: - - sapp_desc.win32_console_utf8 (default: false) - When set to true, the output console codepage will be switched - to UTF-8 (and restored to the original codepage on exit) - - sapp_desc.win32_console_attach (default: false) - When set to true, stdout and stderr will be attached to the - console of the parent process (if the parent process actually - has a console). This means that if the application was started - in a command line window, stdout and stderr output will be printed - to the terminal, just like a regular command line program. But if - the application is started via double-click, it will behave like - a regular UI application, and stdout/stderr will not be visible. - - sapp_desc.win32_console_create (default: false) - When set to true, a new console window will be created and - stdout/stderr will be redirected to that console window. It - doesn't matter if the application is started from the command - line or via double-click. - - MEMORY ALLOCATION OVERRIDE - ========================== - You can override the memory allocation functions at initialization time - like this: - - void* my_alloc(size_t size, void* user_data) { - return malloc(size); - } - - void my_free(void* ptr, void* user_data) { - free(ptr); - } - - sapp_desc sokol_main(int argc, char* argv[]) { - return (sapp_desc){ - // ... - .allocator = { - .alloc = my_alloc, - .free = my_free, - .user_data = ...; - } - }; - } - - If no overrides are provided, malloc and free will be used. - - This only affects memory allocation calls done by sokol_app.h - itself though, not any allocations in OS libraries. - - TEMP NOTE DUMP - ============== - - onscreen keyboard support on Android requires Java :(, should we even bother? - - sapp_desc needs a bool whether to initialize depth-stencil surface - - GL context initialization needs more control (at least what GL version to initialize) - - application icon - - the UPDATE_CURSOR event currently behaves differently between Win32 and OSX - (Win32 sends the event each frame when the mouse moves and is inside the window - client area, OSX sends it only once when the mouse enters the client area) - - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy - at the latest but should do it earlier, in onStop, as an app is "killable" after onStop - on Android Honeycomb and later (it can't be done at the moment as the app may be started - again after onStop and the sokol lifecycle does not yet handle context teardown/bringup) - - - LICENSE - ======= - zlib/libpng license - - Copyright (c) 2018 Andre Weissflog - - This software is provided 'as-is', without any express or implied warranty. - In no event will the authors be held liable for any damages arising from the - use of this software. - - Permission is granted to anyone to use this software for any purpose, - including commercial applications, and to alter it and redistribute it - freely, subject to the following restrictions: - - 1.

This + function is called very early, usually at the start of the + platform's entry function (e.g. main or WinMain). You should do as + little as possible here, since the rest of your code might be called + from another thread (this depends on the platform): + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + .width = 640, + .height = 480, + .init_cb = my_init_func, + .frame_cb = my_frame_func, + .cleanup_cb = my_cleanup_func, + .event_cb = my_event_func, + ... + }; + } + + There are many more setup parameters, but these are the most important. + For a complete list search for the sapp_desc structure declaration + below. + + DO NOT call any sokol-app function from inside sokol_main(), since + sokol-app will not be initialized at this point. + + The .width and .height parameters are the preferred size of the 3D + rendering canvas. The actual size may differ from this depending on + platform and other circumstances. Also the canvas size may change at + any time (for instance when the user resizes the application window, + or rotates the mobile device). You can just keep .width and .height + zero-initialized to open a default-sized window (what "default-size" + exactly means is platform-specific, but usually it's a size that covers + most of, but not all, of the display). + + All provided function callbacks will be called from the same thread, + but this may be different from the thread where sokol_main() was called. + + .init_cb (void (*)(void)) + This function is called once after the application window, + 3D rendering context and swap chain have been created. The + function takes no arguments and has no return value. + .frame_cb (void (*)(void)) + This is the per-frame callback, which is usually called 60 + times per second. This is where your application would update + most of its state and perform all rendering. + .cleanup_cb (void (*)(void)) + The cleanup callback is called once right before the application + quits. + .event_cb (void (*)(const sapp_event* event)) + The event callback is mainly for input handling, but is also + used to communicate other types of events to the application. Keep the + event_cb struct member zero-initialized if your application doesn't require + event handling. + .fail_cb (void (*)(const char* msg)) + The fail callback is called when a fatal error is encountered + during start which doesn't allow the program to continue. + Providing a callback here gives you a chance to show an error message + to the user. The default behaviour is SAPP_LOG(msg) + + As you can see, those 'standard callbacks' don't have a user_data + argument, so any data that needs to be preserved between callbacks + must live in global variables. If keeping state in global variables + is not an option, there's an alternative set of callbacks with + an additional user_data pointer argument: + + .user_data (void*) + The user-data argument for the callbacks below + .init_userdata_cb (void (*)(void* user_data)) + .frame_userdata_cb (void (*)(void* user_data)) + .cleanup_userdata_cb (void (*)(void* user_data)) + .event_userdata_cb (void(*)(const sapp_event* event, void* user_data)) + .fail_userdata_cb (void(*)(const char* msg, void* user_data)) + These are the user-data versions of the callback functions. You + can mix those with the standard callbacks that don't have the + user_data argument. + + The function sapp_userdata() can be used to query the user_data + pointer provided in the sapp_desc struct. + + You can also call sapp_query_desc() to get a copy of the + original sapp_desc structure. + + NOTE that there's also an alternative compile mode where sokol_app.h + doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY. + + --- Implement the initialization callback function (init_cb), this is called + once after the rendering surface, 3D API and swap chain have been + initialized by sokol_app. All sokol-app functions can be called + from inside the initialization callback, the most useful functions + at this point are: + + int sapp_width(void) + int sapp_height(void) + Returns the current width and height of the default framebuffer in pixels, + this may change from one frame to the next, and it may be different + from the initial size provided in the sapp_desc struct. + + float sapp_widthf(void) + float sapp_heightf(void) + These are alternatives to sapp_width() and sapp_height() which return + the default framebuffer size as float values instead of integer. This + may help to prevent casting back and forth between int and float + in more strongly typed languages than C and C++. + + double sapp_frame_duration(void) + Returns the frame duration in seconds averaged over a number of + frames to smooth out any jittering spikes. + + int sapp_color_format(void) + int sapp_depth_format(void) + The color and depth-stencil pixelformats of the default framebuffer, + as integer values which are compatible with sokol-gfx's + sg_pixel_format enum (so that they can be plugged directly in places + where sg_pixel_format is expected). Possible values are: + + 23 == SG_PIXELFORMAT_RGBA8 + 27 == SG_PIXELFORMAT_BGRA8 + 41 == SG_PIXELFORMAT_DEPTH + 42 == SG_PIXELFORMAT_DEPTH_STENCIL + + int sapp_sample_count(void) + Return the MSAA sample count of the default framebuffer. + + bool sapp_gles2(void) + Returns true if a GLES2 or WebGL context has been created. This + is useful when a GLES3/WebGL2 context was requested but is not + available so that sokol_app.h had to fallback to GLES2/WebGL. + + const void* sapp_metal_get_device(void) + const void* sapp_metal_get_renderpass_descriptor(void) + const void* sapp_metal_get_drawable(void) + If the Metal backend has been selected, these functions return pointers + to various Metal API objects required for rendering, otherwise + they return a null pointer. These void pointers are actually + Objective-C ids converted with a (ARC) __bridge cast so that + the ids can be tunnel through C code. Also note that the returned + pointers to the renderpass-descriptor and drawable may change from one + frame to the next, only the Metal device object is guaranteed to + stay the same. + + const void* sapp_macos_get_window(void) + On macOS, get the NSWindow object pointer, otherwise a null pointer. + Before being used as Objective-C object, the void* must be converted + back with a (ARC) __bridge cast. + + const void* sapp_ios_get_window(void) + On iOS, get the UIWindow object pointer, otherwise a null pointer. + Before being used as Objective-C object, the void* must be converted + back with a (ARC) __bridge cast. + + const void* sapp_win32_get_hwnd(void) + On Windows, get the window's HWND, otherwise a null pointer.

Otherwise they + return a null pointer. Note that the returned pointers to the + render-target-view and depth-stencil-view may change from one + frame to the next! + + const void* sapp_wgpu_get_device(void) + const void* sapp_wgpu_get_render_view(void) + const void* sapp_wgpu_get_resolve_view(void) + const void* sapp_wgpu_get_depth_stencil_view(void) + These are the WebGPU-specific functions to get the WebGPU + objects and values required for rendering. If sokol_app.h + is not compiled with SOKOL_WGPU, these functions return null. + + const void* sapp_android_get_native_activity(void); + On Android, get the native activity ANativeActivity pointer, otherwise + a null pointer. + + --- Implement the frame-callback function, this function will be called + on the same thread as the init callback, but might be on a different + thread than the sokol_main() function. Note that the size of + the rendering framebuffer might have changed since the frame callback + was called last. Call the functions sapp_width() and sapp_height() + each frame to get the current size. + + --- Optionally implement the event-callback to handle input events. + sokol-app provides the following type of input events: + - a 'virtual key' was pressed down or released + - a single text character was entered (provided as UTF-32 code point) + - a mouse button was pressed down or released (left, right, middle) + - mouse-wheel or 2D scrolling events + - the mouse was moved + - the mouse has entered or left the application window boundaries + - low-level, portable multi-touch events (began, moved, ended, cancelled) + - the application window was resized, iconified or restored + - the application was suspended or restored (on mobile platforms) + - the user or application code has asked to quit the application + - a string was pasted to the system clipboard + - one or more files have been dropped onto the application window + + To explicitly 'consume' an event and prevent that the event is + forwarded for further handling to the operating system, call + sapp_consume_event() from inside the event handler (NOTE that + this behaviour is currently only implemented for some HTML5 + events, support for other platforms and event types will + be added as needed, please open a github ticket and/or provide + a PR if needed). + + NOTE: Do *not* call any 3D API rendering functions in the event + callback function, since the 3D API context may not be active when the + event callback is called (it may work on some platforms and 3D APIs, + but not others, and the exact behaviour may change between + sokol-app versions). + + --- Implement the cleanup-callback function, this is called once + after the user quits the application (see the section + "APPLICATION QUIT" for detailed information on quitting + behaviour, and how to intercept a pending quit - for instance to show a + "Really Quit?" dialog box). Note that the cleanup-callback isn't + guaranteed to be called on the web and mobile platforms. + + MOUSE CURSOR TYPE AND VISIBILITY + ================================ + You can show and hide the mouse cursor with + + void sapp_show_mouse(bool show) + + And to get the current shown status: + + bool sapp_mouse_shown(void) + + NOTE that hiding the mouse cursor is different and independent from + the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when + active (MOUSE LOCK is described below). + + To change the mouse cursor to one of several predefined types, call + the function: + + void sapp_set_mouse_cursor(sapp_mouse_cursor cursor) + + Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore + the standard look. + + To get the currently active mouse cursor type, call: + + sapp_mouse_cursor sapp_get_mouse_cursor(void) + + MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE) + ================================================ + In normal mouse mode, no mouse movement events are reported when the + mouse leaves the windows client area or hits the screen border (whether + it's one or the other depends on the platform), and the mouse move events + (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in + framebuffer pixels in the sapp_event items mouse_x and mouse_y, and + relative movement in framebuffer pixels in the sapp_event items mouse_dx + and mouse_dy. + + To get continuous mouse movement (also when the mouse leaves the window + client area or hits the screen border), activate mouse-lock mode + by calling: + + sapp_lock_mouse(true) + + When mouse lock is activated, the mouse pointer is hidden, the + reported absolute mouse position (sapp_event.mouse_x/y) appears + frozen, and the relative mouse movement in sapp_event.mouse_dx/dy + no longer has a direct relation to framebuffer pixels but instead + uses "raw mouse input" (what "raw mouse input" exactly means also + differs by platform). + + To deactivate mouse lock and return to normal mouse mode, call + + sapp_lock_mouse(false) + + And finally, to check if mouse lock is currently active, call + + if (sapp_mouse_locked()) { ... } + + On native platforms, the sapp_lock_mouse() and sapp_mouse_locked() + functions work as expected (mouse lock is activated or deactivated + immediately when sapp_lock_mouse() is called, and sapp_mouse_locked() + also immediately returns the new state after sapp_lock_mouse() + is called. + + On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave + differently, as dictated by the limitations of the HTML5 Pointer Lock API: + + - sapp_lock_mouse(true) can be called at any time, but it will + only take effect in a 'short-lived input event handler of a specific + type', meaning when one of the following events happens: + - SAPP_EVENTTYPE_MOUSE_DOWN + - SAPP_EVENTTYPE_MOUSE_UP + - SAPP_EVENTTYPE_MOUSE_SCROLL + - SAPP_EVENTTYPE_KEY_UP + - SAPP_EVENTTYPE_KEY_DOWN + - The mouse lock/unlock action on the web platform is asynchronous, + this means that sapp_mouse_locked() won't immediately return + the new status after calling sapp_lock_mouse(), instead the + reported status will only change when the pointer lock has actually + been activated or deactivated in the browser. + - On the web, mouse lock can be deactivated by the user at any time + by pressing the Esc key. When this happens, sokol_app.h behaves + the same as if sapp_lock_mouse(false) is called. + + For things like camera manipulation it's most straightforward to lock + and unlock the mouse right from the sokol_app.h event handler, for + instance the following code enters and leaves mouse lock when the + left mouse button is pressed and released, and then uses the relative + movement information to manipulate a camera (taken from the + cgltf-sapp.c sample in the sokol-samples repository + at https://github.com/floooh/sokol-samples): + + static void input(const sapp_event* ev) { + switch (ev->type) { + case SAPP_EVENTTYPE_MOUSE_DOWN: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(true); + } + break; + + case SAPP_EVENTTYPE_MOUSE_UP: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(false); + } + break; + + case SAPP_EVENTTYPE_MOUSE_MOVE: + if (sapp_mouse_locked()) { + cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f); + } + break; + + default: + break; + } + } + + CLIPBOARD SUPPORT + ================= + Applications can send and receive UTF-8 encoded text data from and to the + system clipboard.

Strings that don't fit into the clipboard buffer + (including the terminating zero) will be silently clipped, so it's + important that you provide a big enough clipboard size for your + use case. + + To send data to the clipboard, call sapp_set_clipboard_string() with + a pointer to an UTF-8 encoded, null-terminated C-string. + + NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be + called from inside a 'short-lived event handler', and there are a few + other HTML5-specific caveats to workaround. You'll basically have to + tinker until it works in all browsers :/ (maybe the situation will + improve when all browsers agree on and implement the new + HTML5 navigator.clipboard API). + + To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED + event in your event handler function, and then call sapp_get_clipboard_string() + to obtain the pasted UTF-8 encoded text. + + NOTE that behaviour of sapp_get_clipboard_string() is slightly different + depending on platform: + + - on the HTML5 platform, the internal clipboard buffer will only be updated + right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent, + and sapp_get_clipboard_string() will simply return the current content + of the clipboard buffer + - on 'native' platforms, the call to sapp_get_clipboard_string() will + update the internal clipboard buffer with the most recent data + from the system clipboard + + Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event, + and then call sapp_get_clipboard_string() right in the event handler. + + The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app + as follows: + + - on macOS: when the Cmd+V key is pressed down + - on HTML5: when the browser sends a 'paste' event to the global 'window' object + - on all other platforms: when the Ctrl+V key is pressed down + + DRAG AND DROP SUPPORT + ===================== + PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5 + and on the native desktop platforms (Win32, Linux and macOS) because + of security-related restrictions in the HTML5 drag'n'drop API. The + WASM/HTML5 specifics are described at the end of this documentation + section: + + Like clipboard support, drag'n'drop support must be explicitly enabled + at startup in the sapp_desc struct. + + sapp_desc sokol_main() { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + ... + }; + } + + You can also adjust the maximum number of files that are accepted + in a drop operation, and the maximum path length in bytes if needed: + + sapp_desc sokol_main() { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + .max_dropped_files = 8, // default is 1 + .max_dropped_file_path_length = 8192, // in bytes, default is 2048 + ... + }; + } + + When drag'n'drop is enabled, the event callback will be invoked with an + event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on + the application window. + + After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the + number of dropped files, and their absolute paths by calling separate + functions: + + void on_event(const sapp_event* ev) { + if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) { + + // the mouse position where the drop happened + float x = ev->mouse_x; + float y = ev->mouse_y; + + // get the number of files and their paths like this: + const int num_dropped_files = sapp_get_num_dropped_files(); + for (int i = 0; i < num_dropped_files; i++) { + const char* path = sapp_get_dropped_file_path(i); + ... + } + } + } + + The returned file paths are UTF-8 encoded strings. + + You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path() + anywhere, also outside the event handler callback, but be aware that the + file path strings will be overwritten with the next drop operation. + + In any case, sapp_get_dropped_file_path() will never return a null pointer, + instead an empty string "" will be returned if the drag'n'drop feature + hasn't been enabled, the last drop-operation failed, or the file path index + is out of range. + + Drag'n'drop caveats: + + - if more files are dropped in a single drop-action + than sapp_desc.max_dropped_files, the additional + files will be silently ignored + - if any of the file paths is longer than + sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8 + encoding) the entire drop operation will be silently ignored (this + needs some sort of error feedback in the future) + - no mouse positions are reported while the drag is in + process, this may change in the future + + Drag'n'drop on HTML5/WASM: + + The HTML5 drag'n'drop API doesn't return file paths, but instead + black-box 'file objects' which must be used to load the content + of dropped files. This is the reason why sokol_app.h adds two + HTML5-specific functions to the drag'n'drop API: + + uint32_t sapp_html5_get_dropped_file_size(int index) + Returns the size in bytes of a dropped file. + + void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request) + Asynchronously loads the content of a dropped file into a + provided memory buffer (which must be big enough to hold + the file content) + + To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED + event is received: + + sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){ + .dropped_file_index = 0, + .callback = fetch_cb + .buffer = { + .ptr = buf, + .size = sizeof(buf) + }, + .user_data = ... + }); + + Make sure that the memory pointed to by 'buf' stays valid until the + callback function is called! + + As result of the asynchronous loading operation (no matter if succeeded or + failed) the 'fetch_cb' function will be called: + + void fetch_cb(const sapp_html5_fetch_response* response) { + // IMPORTANT: check if the loading operation actually succeeded: + if (response->succeeded) { + // the size of the loaded file: + const size_t num_bytes = response->data.size; + // and the pointer to the data (same as 'buf' in the fetch-call): + const void* ptr = response->data.ptr; + } + else { + // on error check the error code: + switch (response->error_code) { + case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL: + ... + break; + case SAPP_HTML5_FETCH_ERROR_OTHER: + ... + break; + } + } + } + + Check the droptest-sapp example for a real-world example which works + both on native platforms and the web: + + https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c + + HIGH-DPI RENDERING + ================== + You can set the sapp_desc.high_dpi flag during initialization to request + a full-resolution framebuffer on HighDPI displays. The default behaviour + is sapp_desc.high_dpi=false, this means that the application will + render to a lower-resolution framebuffer on HighDPI displays and the + rendered content will be upscaled by the window system composer. + + In a HighDPI scenario, you still request the same window size during + sokol_main(), but the framebuffer sizes returned by sapp_width() + and sapp_height() will be scaled up according to the DPI scaling + ratio. + + Note that on some platforms the DPI scaling factor may change at any + time (for instance when a window is moved from a high-dpi display + to a low-dpi display). + + To query the current DPI scaling factor, call the function: + + float sapp_dpi_scale(void); + + For instance on a Retina Mac, returning the following sapp_desc + struct from sokol_main(): + + sapp_desc sokol_main() { + return (sapp_desc) { + .width = 640, + .height = 480, + .high_dpi = true, + ... + }; + } + + ...the functions the functions sapp_width(), sapp_height() + and sapp_dpi_scale() will return the following values: + + sapp_width: 1280 + sapp_height: 960 + sapp_dpi_scale: 2.0 + + If the high_dpi flag is false, or you're not running on a Retina display, + the values would be: + + sapp_width: 640 + sapp_height: 480 + sapp_dpi_scale: 1.0 + + If the window is moved from the Retina display to a low-dpi external display, + the values would change as follows: + + sapp_width: 1280 => 640 + sapp_height: 960 => 480 + sapp_dpi_scale: 2.0 => 1.0 + + Currently there is no event associated with a DPI change, but an + SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the + framebuffer size changing. + + Per-monitor DPI is currently supported on macOS and Windows. + + APPLICATION QUIT + ================ + Without special quit handling, a sokol_app.h application will quit + 'gracefully' when the user clicks the window close-button unless a + platform's application model prevents this (e.g. on web or mobile). + 'Graceful exit' means that the application-provided cleanup callback will + be called before the application quits. + + On native desktop platforms sokol_app.h provides more control over the + application-quit-process. It's possible to initiate a 'programmatic quit' + from the application code, and a quit initiated by the application user can + be intercepted (for instance to show a custom dialog box). + + This 'programmatic quit protocol' is implemented through 3 functions + and 1 event: + + - sapp_quit(): This function simply quits the application without + giving the user a chance to intervene. Usually this might + be called when the user clicks the 'Ok' button in a 'Really Quit?' + dialog box + - sapp_request_quit(): Calling sapp_request_quit() will send the + event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler + callback, giving the user code a chance to intervene and cancel the + pending quit process (for instance to show a 'Really Quit?' dialog + box). If the event handler callback does nothing, the application + will be quit as usual. To prevent this, call the function + sapp_cancel_quit() from inside the event handler. + - sapp_cancel_quit(): Cancels a pending quit request, either initiated + by the user clicking the window close button, or programmatically + by calling sapp_request_quit(). The only place where calling this + function makes sense is from inside the event handler callback when + the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received. + - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user + clicks the window's close button or application code calls the + sapp_request_quit() function. The event handler callback code can handle + this event by calling sapp_cancel_quit() to cancel the quit. + If the event is ignored, the application will quit as usual. + + On the web platform, the quit behaviour differs from native platforms, + because of web-specific restrictions: + + A `programmatic quit` initiated by calling sapp_quit() or + sapp_request_quit() will work as described above: the cleanup callback is + called, platform-specific cleanup is performed (on the web + this means that JS event handlers are unregisters), and then + the request-animation-loop will be exited. However that's all. The + web page itself will continue to exist (e.g. it's not possible to + programmatically close the browser tab). + + On the web it's also not possible to run custom code when the user + closes a brower tab, so it's not possible to prevent this with a + fancy custom dialog box. + + Instead the standard "Leave Site?" dialog box can be activated (or + deactivated) with the following function: + + sapp_html5_ask_leave_site(bool ask); + + The initial state of the associated internal flag can be provided + at startup via sapp_desc.html5_ask_leave_site. + + This feature should only be used sparingly in critical situations - for + instance when the user would loose data - since popping up modal dialog + boxes is considered quite rude in the web world. Note that there's no way + to customize the content of this dialog box or run any code as a result + of the user's decision. Also note that the user must have interacted with + the site before the dialog box will appear. These are all security measures + to prevent fishing. + + The Dear ImGui HighDPI sample contains example code of how to + implement a 'Really Quit?' dialog box with Dear ImGui (native desktop + platforms only), and for showing the hardwired "Leave Site?" dialog box + when running on the web platform: + + https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html + + FULLSCREEN + ========== + If the sapp_desc.fullscreen flag is true, sokol-app will try to create + a fullscreen window on platforms with a 'proper' window system + (mobile devices will always use fullscreen). The implementation details + depend on the target platform, in general sokol-app will use a + 'soft approach' which doesn't interfere too much with the platform's + window system (for instance borderless fullscreen window instead of + a 'real' fullscreen mode). Such details might change over time + as sokol-app is adapted for different needs. + + The most important effect of fullscreen mode to keep in mind is that + the requested canvas width and height will be ignored for the initial + window size, calling sapp_width() and sapp_height() will instead return + the resolution of the fullscreen canvas (however the provided size + might still be used for the non-fullscreen window, in case the user can + switch back from fullscreen- to windowed-mode). + + To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen(). + + To check if the application window is currently in fullscreen mode, + call sapp_is_fullscreen(). + + WINDOW ICON SUPPORT + =================== + Some sokol_app.h backends allow to change the window icon programmatically: + + - on Win32: the small icon in the window's title bar, and the + bigger icon in the task bar + - on Linux: highly dependent on the used window manager, but usually + the window's title bar icon and/or the task bar icon + - on HTML5: the favicon shown in the page's browser tab + + NOTE that it is not possible to set the actual application icon which is + displayed by the operating system on the desktop or 'home screen'. Those + icons must be provided 'traditionally' through operating-system-specific + resources which are associated with the application (sokol_app.h might + later support setting the window icon from platform specific resource data + though). + + There are two ways to set the window icon: + + - at application start in the sokol_main() function by initializing + the sapp_desc.icon nested struct + - or later by calling the function sapp_set_icon() + + As a convenient shortcut, sokol_app.h comes with a builtin default-icon + (a rainbow-colored 'S', which at least looks a bit better than the Windows + default icon for applications), which can be activated like this: + + At startup in sokol_main(): + + sapp_desc sokol_main(...) { + return (sapp_desc){ + ... + icon.sokol_default = true + }; + } + + Or later by calling: + + sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true }); + + NOTE that a completely zero-initialized sapp_icon_desc struct will not + update the window icon in any way. This is an 'escape hatch' so that you + can handle the window icon update yourself (or if you do this already, + sokol_app.h won't get in your way, in this case just leave the + sapp_desc.icon struct zero-initialized). + + Providing your own icon images works exactly like in GLFW (down to the + data format): + + You provide one or more 'candidate images' in different sizes, and the + sokol_app.h platform backends pick the best match for the specific backend + and icon type. + + For each candidate image, you need to provide: + + - the width in pixels + - the height in pixels + - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844 + on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44) + + For instance, if you have 3 candidate images (small, medium, big) of + sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup + like this: + + // the actual pixel data (RGBA8, origin top-left) + const uint32_t small[16][16] = { ... }; + const uint32_t medium[32][32] = { ... }; + const uint32_t big[64][64] = { ... }; + + const sapp_icon_desc icon_desc = { + .images = { + { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) }, + { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) }, + // ...or without the SAPP_RANGE helper macro: + { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } } + } + }; + + An sapp_icon_desc struct initialized like this can then either be applied + at application start in sokol_main: + + sapp_desc sokol_main(...) { + return (sapp_desc){ + ... + icon = icon_desc + }; + } + + ...or later by calling sapp_set_icon(): + + sapp_set_icon(&icon_desc); + + Some window icon caveats: + + - once the window icon has been updated, there's no way to go back to + the platform's default icon, this is because some platforms (Linux + and HTML5) don't switch the icon visual back to the default even if + the custom icon is deleted or removed + - on HTML5, if the sokol_app.h icon doesn't show up in the browser + tab, check that there's no traditional favicon 'link' element + is defined in the page's index.html, sokol_app.h will only + append a new favicon link element, but not delete any manually + defined favicon in the page + + For an example and test of the window icon feature, check out the the + 'icon-sapp' sample on the sokol-samples git repository. + + ONSCREEN KEYBOARD + ================= + On some platforms which don't provide a physical keyboard, sokol-app + can display the platform's integrated onscreen keyboard for text + input. To request that the onscreen keyboard is shown, call + + sapp_show_keyboard(true); + + Likewise, to hide the keyboard call: + + sapp_show_keyboard(false); + + Note that on the web platform, the keyboard can only be shown from + inside an input handler. On such platforms, sapp_show_keyboard() + will only work as expected when it is called from inside the + sokol-app event callback function. When called from other places, + an internal flag will be set, and the onscreen keyboard will be + called at the next 'legal' opportunity (when the next input event + is handled). + + OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY) + ====================================================== + In its default configuration, sokol_app.h "hijacks" the platform's + standard main() function. This was done because different platforms + have different main functions which are not compatible with + C's main() (for instance WinMain on Windows has completely different + arguments). However, this "main hijacking" posed a problem for + usage scenarios like integrating sokol_app.h with other languages than + C or C++, so an alternative SOKOL_NO_ENTRY mode has been added + in which the user code provides the platform's main function: + + - define SOKOL_NO_ENTRY before including the sokol_app.h implementation + - do *not* provide a sokol_main() function + - instead provide the standard main() function of the platform + - from the main function, call the function ```sapp_run()``` which + takes a pointer to an ```sapp_desc``` structure. + - ```sapp_run()``` takes over control and calls the provided init-, frame-, + shutdown- and event-callbacks just like in the default model, it + will only return when the application quits (or not at all on some + platforms, like emscripten) + + NOTE: SOKOL_NO_ENTRY is currently not supported on Android. + + WINDOWS CONSOLE OUTPUT + ====================== + On Windows, regular windowed applications don't show any stdout/stderr text + output, which can be a bit of a hassle for printf() debugging or generally + logging text to the console. Also, console output by default uses a local + codepage setting and thus international UTF-8 encoded text is printed + as garbage. + + To help with these issues, sokol_app.h can be configured at startup + via the following Windows-specific sapp_desc flags: + + sapp_desc.win32_console_utf8 (default: false) + When set to true, the output console codepage will be switched + to UTF-8 (and restored to the original codepage on exit) + + sapp_desc.win32_console_attach (default: false) + When set to true, stdout and stderr will be attached to the + console of the parent process (if the parent process actually + has a console). This means that if the application was started + in a command line window, stdout and stderr output will be printed + to the terminal, just like a regular command line program. But if + the application is started via double-click, it will behave like + a regular UI application, and stdout/stderr will not be visible. + + sapp_desc.win32_console_create (default: false) + When set to true, a new console window will be created and + stdout/stderr will be redirected to that console window. It + doesn't matter if the application is started from the command + line or via double-click. + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc){ + // ... + .allocator = { + .alloc = my_alloc, + .free = my_free, + .user_data = ..., + } + }; + } + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_app.h + itself though, not any allocations in OS libraries. + + + LOG FUNCTION OVERRIDE + ===================== + You can override the log function at initialization time like this: + + void my_log(const char* message, void* user_data) { + printf("sapp says: \s\n", message); + } + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc){ + // ... + .logger = { + .log_cb = my_log, + .user_data = ..., + } + }; + } + + If no overrides are provided, puts will be used on most platforms. + On Android, __android_log_write will be used instead. + + + TEMP NOTE DUMP + ============== + - onscreen keyboard support on Android requires Java :(, should we even bother? + - sapp_desc needs a bool whether to initialize depth-stencil surface + - GL context initialization needs more control (at least what GL version to initialize) + - application icon + - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy + at the latest but should do it earlier, in onStop, as an app is "killable" after onStop + on Android Honeycomb and later (it can't be done at the moment as the app may be started + again after onStop and the sokol lifecycle does not yet handle context teardown/bringup) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.
