This states that
gtk_widget_set_app_paintable is gone:
If I understand correctly now decorations are part of Gtk and if I use GdkSurface instead of GtkWindow I loose default decorations.
So I have paint it all myself, including decorations with GdkSurface?
I’m looking for a midterm where I could re-use existing/default decorations and still be able to paint into a window (or a widget that is directly descendant).
I think you’ve got yourself confused somewhere,
gtk_widget_set_app_paintable never really did much and doesn’t really have anything to do with decorations
GdkSurface is analogous to the old GdkWindow not GtkWindow - it’s a low-level windowing concept
If, for some reason, you decided to use a GdkSurface without a GtkWindow you would need to do a lot yourself
gtk_window_set_titlebar a drawing area? Though really I’m not sure why you can’t use GtkHeaderBar?
I thought the removal of
gtk_widget_set_app_paintable made it impossible to paint to GtkWindow directly. Can I still do it?
Following this thought I had the idea of using a GdkSurface so I could draw on it, but would loose default decorations.
What I want is default decorations + ability to draw a buffer directly to the window.
I mean you can still connect to the draw signal, not entirely sure why you’d want to?
I’d suggest sticking a GtkDrawingArea in a GtkWindow
