you don't draw in a timer. you also should not attempt to cache cairo contexts. if you want to draw, call Widget::queue_draw() which will eventually call your expose event handler. create a new cairo context there and draw with it and then release it. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
