Cool. One of the reasons I had closed the PoC webview PR (#1452) was because webview had appeared to be dead with about a year of no commits, but it seems to have been brought back to life earlier this year. We should request a stable release tag if we wanna commit to it as a framework for a dex desktop app. |

I'm not commited to WebView at all. Honestly, if I didn't have anyone to answer to, I would just include a chromium binary with the distro and run it with |
If licensing permits, I wouldn't object to that given we can sandbox the thing so it doesn't fiddle with the user's chromium settings. |
I'm pretty sure we'd have to have the app behave like a "downloader" to fetch the browser because third party binaries with ours is what would be problematic in terms of licensing. |

Still Webview, just a separate process for windows. |

When this goes in we can squash with you as author. After squash, git commit --amend --author="buck54321 <buck54321@gmail.com>", and ideally tweaked commit message like
add cmd/dexc-desktop
Introduce a new cmd, dexc-desktop. This coordinates a WebView
window with our normal dexc stack.
Prepare Debian archive for installation, including control files,
Desktop Entry specificiation and icons. User can install with
their preferred package manager.
Moves some common utilities to a new package client/app.
Co-authored-by: Jonathan Chappelow <chappjc@gmail.com>
The pkg-debian.sh addition would ideally be a second commit since dexc-desktop is mostly unrelated to Debian.

This seems firmly in the realm of user/os setup. At best an installer. Do you mean this app itself that is running dex core would make changes the the user/os env to make auto-startup?
My view is that users start programs that they want to run. We can facilitate system service setup with scripts, systemd configs, installer, etc., but I don't think this app code should be concerned with that.

Ran the dexc-desktop on my Mac and hit this panic immediately. Panic logs |

@ukane-philemon Would you try a fresh project with just this to see if it works on your mac? package main
import "github.com/webview/webview"
func main() {
w := webview.New(false)
defer w.Destroy()
w.SetTitle("Example")
w.SetSize(480, 320, webview.HintNone)
w.Navigate("http://127.0.0.1:8080")
w.Run()
} |

Looks like main needs a refactor so that this is in a goroutine and main is just blocking on systray.Run.

If I shut down before a webview is opened, I see a panic since cmd.Process will still be nil but have been added to m.windows giving another process an opportunity to access cmd.Process.

We should also set a min width here. w.SetSize(600, 600, webview.HintMin)(min width & height can be anything > 100). The webview almost disappears when I click on minimise and it doesn't look good if users can minimise the window all the way.

We should also defer cancel() here since we will no longer be able to create new windows if this goroutine is exited.
