The event-delegation model has two advantages over the event-inheritance model. First, it enables event handling which handled by objects other than the ones that generate the their events. This allows a clean separation between a component''s design and its usage. Another advantage of the event-delegation model is that it performs much better in applications where many events are generated. This performance improvement is due to the fact that the event-delegation model does not have to repeatedly process unhandled events, as in the case of the event-inheritance model.
