Hmmm,
    It would really be a plus IMO if people would post these things
to bugzilla, at least the discussion could be archived in a more sensable
manner.

The GTK+ tradition AFAIK goes something like this:

/* Call this on each toplevel
 */
gtk_container_forech(GTK_CONTAINER(toplevel), 
                                       recursive_foreach, callback);

recursive_foreach(GtkWidget *widget, gpointer cb)
{
         if (GTK_IS_CONTAINER(widget)) {
                gtk_container_foreach(widget, recursive_foreach, cb);
         }
         cb(widget);
}


Cheers,
