【bevy_webview_wry】Support for Linux(Wayland)

[not-elm]

I think it will probably work

[not-elm]

I looked into it, but it seems impossible because winit does not support gtk.

This may change after rust-windowing/winit#3433

@not-elm that issue is closed. will bevy_webview_wry work on wayland now?

[TimTheBig]

I believe that all that being resolved does is unblock adding a gtk backend to winit. There is a winit fork with gtk support, if you want you can use that as a base for a winit-gtk backend

[not-elm]

I haven’t been able to check the latest version of winit yet, but does this mean we need to create a gtk backend first?
Honestly, I don’t have much experience with wayland/linux, and I also don’t have a comfortable test environment, so this will likely take me a while.
I'd like to leave this to someone who's already comfortable using Linux, but is there anyone who'd like to give it a try? I'll provide support as much as I can.
