Floating windows on Linux

Bonjour,

After searching on the forum, I tried to use “gtk_window_set_keep_above” to have floating windows under Linux.
I’m using Ubuntu via Parallels on a MacBook Pro M3.
And my floating window doesn’t stay on top of the document windows.
I’d like to have the equivalent of a “global floating window” like with macOS.

Does someone have an example to do that?

On Fedora, floating windows work without declare.
But not on Ubuntu.

Do you use the MBS plugins? There’s a function for that (presumably using the API you’ve tried, but you may give it a try).
Check DesktopWindow.GTKWindow.SetKeepAbove.

No, I don’t use MBS plugin for that.
