To process all pending events pending as pmap_expose needs the static pixbuf "alive" and it's unref'ed at the end of this function. But it's broken as the next expose event will get a pixbuf that may not exists as dispMap is storing a pointer to a gobject that have been destroyed. This scheme assumes that the expose event will only happen when you call queue_draw, but any overlapping of other application's window over this widget - among a myriad other causes - will need redraw to happen - thus the expose-event signal will be raised. You can get rid of this loop, and you must not destroy the pixbuf until the widget is destroyed. -- Iago Rubio _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
