It think that this code is OS-specific. E.g. for Win32 it handles WM_PAINT
and creates an event using gdk_event_new (GDK_EXPOSE). This event, though,
is not converted into a signal for GdkWindow. GtkMain handles the event
(see gtkmain.c, gtk_main_do_event) by calling gtk_widget_send_expose.

As for "draw", each widget registers its handler. E.g. see gtk_button_draw
in gtkbutton.c as an example.

BTW, does anybody know the status of prepackaged GtkAda for Debian and
Fedora?
