The event-delegation model has two advantages over the event-inheritance model. First, it enables event
handling to be handled by objects other than the ones that generate the events (or their containers). This allows a clean separation between a component's design and its use. The other advantage of the eventdelegation
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- legation model does not have to repeatedly process unhandled events, as is the case of the event-inheritance model.
