no, every object has its own event handler. the one distinction is that
is a single event handler, not one per event type. so you end up a
generic handler of the form:

	int handler (GdkEventAny *event) {

	    switch (event->type) {
	    case GDK_BUTTON_PRESS:
	      ... do button press stuff ...
	      break;

	    // etc
	    }
	
	    return one_for_handled_zero_for_not_handled;
        }
