Presumably your event code calls gtk_redraw_exposed_area? This part isn't
actually generalised but is in fact called directly from the native event
loop.
Yes, it does. Right now I am hooking into one of the signals generated by
the widget instead of doing it directly from my new subclass of GtkFixed,
but...
The interesting thing is that if I don't hook the generic 'event' driver,
redisplay works. But then of course I don't get any input from the
user. :) Ought to be an interesting day. :)
