Breaking Changes

  • Removed ImFontAtlas::AddCustomRectRegular() unnecessary first argument ID. Please note that this is a Beta api and will likely be reworked in order to support multi-DPI across multiple monitor s.
  • Renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete).
  • Removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. Kept inline redirection function (will obsolete).
  • Removed obsoleted CalcItemRectClosestPoint() entry point (has been asserting since December 2017).

Other Changes

  • TreeNode: Fixed bug where BeginDragDropSource() failed when the _OpenOnDoubleClick flag is enabled (bug introduced in 1.76, but pre-1.76 it would also fail unless the _OpenOnArrow flag was also set, and _OpenOnArrow is frequently set along with _OpenOnDoubleClick).
  • TreeNode: Fixed bug where dragging a payload over a TreeNode() with either _OpenOnDoubleClick or _OpenOnArrow would open the node. (#143)
  • Windows: Fix unintended feedback loops when resizing windows close to main viewport edges. [@rokups]
  • Tabs: Added style.TabMinWidthForUnselectedCloseButton settings:
    • Set to 0.0f (default) to always make a close button appear on hover (same as Chrome, VS).
    • Set to FLT_MAX to only display a close button when selected (merely hovering is not enough).
    • Set to an intermediary value to toggle behavior based on width (same as Firefox).
  • Tabs: Added a ImGuiTabItemFlags_NoTooltip flag to disable the tooltip for individual tab item (vs ImGuiTabBarFlags_NoTooltip for entire tab bar). [@Xipiryon]
  • Popups: All functions capable of opening popups (OpenPopup*, BeginPopupContext*) now take a new ImGuiPopupFlags sets of flags instead of a mouse button index. The API is automatically backward compatible as ImGuiPopupFlags is guaranteed to hold mouse button index in the lower bits.
  • Popups: Added ImGuiPopupFlags_NoOpenOverExistingPopup for OpenPopup*/BeginPopupContext* functions to first test for the presence of another popup at the same level.
  • Popups: Added ImGuiPopupFlags_NoOpenOverItems for BeginPopupContextWindow() - similar to testing for !IsAnyItemHovered() prior to doing an OpenPopup().
  • Popups: Added ImGuiPopupFlags_AnyPopupId and ImGuiPopupFlags_AnyPopupLevel flags for IsPopupOpen(), allowing to check if any popup is open at the current level, if a given popup is open at any popup level, if any popup is open at all.
  • Popups: Fix an edge case where programmatically closing a popup while clicking on its empty space would attempt to focus it and close other popups. (#2880)
  • Popups: Fix BeginPopupContextVoid() when clicking over the area made unavailable by a modal. (#1636)
  • Popups: Clarified some of the comments and function prototypes.
  • Modals: BeginPopupModal() doesn't set the ImGuiWindowFlags_NoSavedSettings flag anymore, and will not always be auto-centered. Note that modals are more similar to regular windows than they are to popups, so api and behavior may evolve further toward embracing this. (#915, #3091). Enforce centering using e.g. SetNextWindowPos(io.DisplaySize * 0.5f, ImGuiCond_Appearing, ImVec2(0.5f,0.5f)).
  • Metrics: Added a "Settings" section with some details about persistent ini settings.
  • Nav, Menus: Fix vertical wrap-around in menus or popups created with multiple appending calls to BeginMenu()/EndMenu() or BeginPopup()/EndPopup()`. (#3223, #1207) [@rokups]
  • Drag and Drop: Fixed unintended fallback "..." tooltip display during drag operation when
    drag source uses _SourceNoPreviewTooltip flags. (#3160) [@rokups]
  • Columns: Lower overhead on column switches and switching to background channel.
    Benefits Columns but was primarily made with Tables in mind!
  • Fonts: Fix GetGlyphRangesKorean() end-range to end at 0xD7A3 (instead of 0xD79D). (#348, #3217) [@marukrap]
  • ImDrawList: Fixed an issue where draw command merging or primitive unreserve while crossing the VtxOffset boundary would lead to draw commands with wrong VtxOffset. (#3129, #3163, #3232, #2591) [@thedmd, @ShironekoBen, @sergeyn, @ocornut]
  • ImDrawList, ImDrawListSplitter, Columns: Fixed an issue where changing channels with different TextureId, VtxOffset would incorrectly apply new settings to draw channels. (#3129, #3163) [@ocornut, @thedmd, @ShironekoBen]
  • ImDrawList, ImDrawListSplitter, Columns: Fixed an issue where starting a split when current VtxOffset was not zero would lead to draw commands with wrong VtxOffset. (#2591)
  • ImDrawList, ImDrawListSplitter, Columns: Fixed an issue where starting a split right after a callback draw command would incorrectly override the callback draw command.
  • ImDrawList: Fixed minor bug introduced in 1.75 where AddCircle() with 12 segments would generate an extra unrequired vertex. [@ShironekoBen]
  • Misc, Freetype: Fix for rare case where FT_Get_Char_Index() succeeds but FT_Load_Glyph() fails.
  • Docs: Improved and moved font documentation to docs/FONTS.md so it can be readable on the web. Updated various links/wiki accordingly. Added FAQ entry about DPI. (#2861) [@ButternCream, @ocornut]
  • CI: Added CI test to verify we're never accidentally dragging libstdc++ (on some compiler setups, static constructors for non-pod data seems to drag in libstdc++ due to thread-safety concerns). Fixed a static constructor which led to this dependency on some compiler setups.
  • Backends: Win32: Support for #define NOGDI, won't try to call GetDeviceCaps(). (#3137, #2327)
  • Backends: Win32: Fix _WIN32_WINNT < 0x0600 (MinGW defaults to 0x502 == Windows 2003). (#3183)
  • Backends: SDL: Report a zero display-size when window is minimized, consistent with other back-ends, making more render/clipping code use an early out path.
  • Backends: OpenGL: Fixed handling of GL 4.5+ glClipControl(GL_UPPER_LEFT) by inverting the projection matrix top and bottom values. (#3143, #3146) [@u3shit]
  • Backends: OpenGL: On OSX, if unspecified by app, made default GLSL version 150. (#3199) [@albertvaka]
  • Backends: OpenGL: Fixed loader auto-detection to not interfere with ES2/ES3 defines. (#3246) [@funchal]
  • Backends: Vulkan: Fixed error in if initial frame has no vertices. (#3177)
  • Backends: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData structure didn't have any vertices. (#2697) [@kudaba]
  • Backends: OSX: Added workaround to avoid fast mouse clicks. (#3261, #1992, #2525) [@nburrus]
  • Examples: GLFW+Vulkan, SDL+Vulkan: Fix for handling of minimized windows. (#3259)
  • Examples: Apple: Fixed example_apple_metal and example_apple_opengl2 using imgui_impl_osx.mm not forwarding right and center mouse clicks. (#3260) [@nburrus]

Other branches & Beta features!

The tables (#2957) features is still available for testing. When it stabilize we will merge it to master (expected to be part of 1.80).

Tables

Some user-visible changes from 1.76 in 1.77 related to the tables branch include:

  • Tables: Restore width/weight saving/loading code. Non-weighted width are font/DPI change friendly.
  • Tables: Resizing weighted column preserve sum of weights. Fix ResizedColumn init leading to undesirable TableSetColumnWidth() on first run.
  • Tables: Added TableGetHoveredColumn(), simplifying TableAutoHeaders() toward aim of it being a user-land function.
  • Tables: Made TableHeader() responsible for opening per-column context menu to move responsibility away from TableAutoHeaders().
  • Tables: Fix TableDrawMergeChannels() mistakenly merging unfrozen columns ClipRect with host ClipRect.
  • Tables: Fix assert/crash when a visible column is clipped in a multi clip group situation.
  • Tables: Fix sort specs sometimes incorrectly reporting sort spec count when table loses _MultiSortable flag during runtime.
  • Tables: Fixed a manual resize path not marking settings as dirty, TableSortSpecsSanitize() doesn't need to test table->IsInitializing
  • Tables: Try to report contents width to outer window, generally better auto-fit.
  • Tables: Fixed incorrect application of CursorMaxPos.x. (#3162)
  • Tables: Fixed ignoring DefaultHide or DefaultSort data from flags when loading settings that don't have them.
  • Tables: Not flagging whole column as SkipItems based on clipping visibility (would break layout).
  • Tables: Allow hot-reload of settings (merge policy), tidying up settings code.
  • Tables: Browse settings list in Metrics->Settings.
  • Tables: Demo: Custom per-popup popups, demonstrate TableGetHoveredColumn() and `ImGuiPopupFlags_NoOpenOverExistingPopup.
  • Tables: Added plenty of regression tests in imgui_dev private repository.

The docking (#2109) and multi-viewports (#1542) features are available in the docking branch, they are in beta but actively maintained and being used by many teams already. Your continuous feedback is always appreciated.

Some of changes from 1.76 in 1.77 related to the docking branch (multi-viewport and docking features) include:

  • Viewports: Don't set ImGuiViewportFlags_NoRendererClear when ImGuiWindowFlags_NoBackground is set. (#3213)
  • Viewports: Report minimized viewports as zero DisplaySize to be consistent with main branch + comments (#1542)
  • Docking, Settings: Allow reload of settings data at runtime. (#2573)
  • Backends, GLFW: Fix windows resizing incorrectly on Linux due to GLFW firing window positioning callbacks on next frame after window is resized manually. (#2117)
  • Backends: DX12: Fix OBJECT_DELETED_WHILE_STILL_IN_USE on viewport resizing. (#3210)
  • Backends: DX12: Fix for crash caused by early resource release. (#3121)
  • Backends, Win32: Request monitor update when dpi awarness is enabled to make sure they have the correct dpi settings.

There's a CMake pull-request (#1713) if you prefer a traditional CMake integration over registering imgui sources files in your own project. There's a premake5 branch if you prefer the saner and nicer Visual Studio projects generated by premake.

Help wanted!

  • If your company uses Dear ImGui, you can reach out to contact at dearimgui.com.
  • Dear ImGui is looking for a technical writer to help writing technical articles, tutorials and documentation. Please reach out if you are interesting in helping!.
  • Multi-viewports in particular needs help and bug-fixes on Linux and Mac. Specific workarounds for both SDL and GLFW are becoming highly desirable. I am myself not a Linux nor Mac users and those platforms have been lagging behind in term of multi-viewport supports. (#2117).
  • The Vulkan renderer appears to have issues (see vulkan tag)
  • Browsing issues and todo list you may find something something to contribute to!

NetImGui https://github.com/sammyfreg/netImgui
by @sammyfreg: "NetImgui is a library to remotely display and control Dear ImGui menus with an associated netImgui server application. Designed to painlessly integrate into existing codebase with few changes required to the existing logic.
Initially created to assist game developers in debugging their game from a PC while it runs on console. However, its use can easily be extended to other fields."
