Interesting, thanks for taking the time to compute this!
Is there a good GTK4 Python tutorial now, or good reference documentation? I'm still confused at all the PyGobject thingies, and I don't know what are the major differences between GTK3 and GTK4 when it comes to GUI programming...
@pieq @GerryT @gnome The PyGObject website has all the links: https://pygobject.gnome.org/
The GNOME documentation also has code examples in Python: https://developer.gnome.org
