Here's a possibility that seems to work: I used event_handler_set to define an event handler that filters out all events (by not calling main_do_event) except EXPOSE while the long-running operation is underway. I wish that there were a way to restore the default event handler, but there is only a set method. Anything bad about this solution? -- Jeffrey Barish _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
