Hi Florian,

I thought they had Gtk-4 examples as well. But anyway, I cooked a
pygobject version of this drawing-widget example, attached.
Could you:
install pygobject
[ run its test-suite ? - it used to fail, in Guix
Drop this example somewhere:
chmod a+x drawing-widget.py
./drawing-widget.py
Thanks,
David
