You can update the variable in response to the widget's 'changed' signal. To go the other way, you will need to write a setter function that is always used to set the variable, and have it update the widget. If you're writing your own GObjects for this app, you could make the variable a property of some object, but that might be overkill. - Michael _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
