Feature Request - GtkHeaderBar title bar implementation for Linux

[igor-cali]

Does wxWidgets support the Gnome-like window title bar (GtkHeaderBar) in linux platforms?

I would like to understand how buttons and menu can be placed in the title bar. Is there any tutorial available (if this is supported by wxWidgets)?

wxWidgets version: 3.2.x (and 3.0.x);
OS Platform: Ubuntu 22.04.1; Gnome Desktop enviroment.
IDE: CodeBlocks / wxFormBuilder

There is no support for this yet. It would be definitely nice to have it because it's a big part of native look and feel.

The first thing that needs to be done here is to find some common of API which would cover this and at least combined macOS toolbar (which is somewhat similar) too and can be mapped to something reasonable under MSW and the other platforms without native support for this.

The second thing would be to actually implement it...

Any help/contributions would be wholeheartedly welcome!
