[Help wanted] Default window decorations color

[itspers]

Big chance its not WSLg issue, but maybe somebody will able to tell where to look:

Most apps respect current GTK_THEME and use window decorations from it. But some, most important JetBrains IDEs won't and for example xcalc.

What part of this magic system is responsible to choose what window decoration theme to use? Can i force it to use some dark theme by default?

when I use JetBrains IDEs, I find that there is no full screen model in view tool. Can you use the full screen model?

no, but it wasn't there in 'old' xserver mode as well, im not sure if its linux versions of Jetbrains apps or particular problem with WSL...

so sad .i hope jetbrains or microsoft can solve this.

Thanks for the suggestion. Who paints the window decoration depends on the application. If the app let the window manager paint it, than it's the window manager inside of Weston that paints it (the right side window). We're currently just using the default theme, was was good enough for the preview :-)... we would like to eventually add a theme that more closely resemble Windows itself and to synchronize it with your Windows themes, but that is some ways out.

Other application can decide to paint those area themselves instead (the left case)... in that case any system level themes will have no effect and instead this is controlled entirely by the application itself (or the framework it uses).

This will be also not ideal solution. Vcxsrv/x410/gWsl using Windows native decorations in such cases without CSD and it results to same white window headers if you using light windows theme.

@spronovo is it theoretically possible to ssh somehow to running distro and install-switch theme? Or it not worth trying and need only to make own build from sources?

[spronovo]

The system distro is mounted as read-only... so any changes you make it to are discarded when WSL is restarted. The servicing model we have for the system distro is a simple throwaway and replace with the new one... if we allowed you to persist data in it you would be loosing it on update. If you want a truly custom experience, building your own system distro is one way to go... but you'll need to keep rebuilding as we provide updates if you want to benefit from those fixes and improvement.

Apart from theming, which would be super nice, the window decoration does not integrate well into windows.
For example, I would have expected being able to drag it to the edge of the screen to resize it or drag it when the window is maximized to exit fullscreen.

Would it be possible to render the window decoration (unless the application renders its own) in windows, maybe through the RDP client? Wouldn't we get theming & better windows integration for "free" then?

No, because #37 (comment)

It will be same as now on all existing xservers - or dark or light, without respect for application content at all

How did you get your gtk apps to use a different gtk theme at all? I couldn't make a difference even though I set GTK_THEME in /etc/profile...

Via gnome tweaks, maybe.

$ sudo apt install gnome-tweaks
$ gnome-tweaks &

Then you can download a custom theme from Gnome Look and select it on tweaks window.

but i can not select the theme in gnome-tweaks after installed gnome-tweaks,can you tell me how did you do that

Microsoft-Edge-Dev for Linux now is another one of the apps that no longer displays its window decorations like previous builds of the app once did. Now, Edge for Linux no longer displays its own window decorations in Wayland in WSLg since its last build.

VSCode also looks great when you change the titlebar style to custom
