No they did not :-)
In fact, the code can be much simplified now:
function Custom_Draw
(Self : access Gtk_Widget_Record'Class;
Cr : Cairo.Cairo_Context) return Boolean is ...
Obj.On_Draw (Custom_Draw'Access); -- defined in gtk-widget.ads
No need for the marshallers any more in almost all cases. I recommend using
the new On_* procedures defined in all the GtkAda packages, they might signal
handling much easier, and safer too (since the compiler can check statically that
the signal is valid for the given widget)
