Do this, use: style_cx = widget.get_style_context() new_path = Gtk.WidgetPath() new_path.append_type(Gtk.Window); new_path.append_type(Gtk.ProgressBar); style_cx.set_path(new_path) ... (And of course instead of Gtk.ProgressBar, use any widget type you need to draw) -- Andrew _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
