Event model is based on the concept of an 'Event Source' and 'Event Listeners'. Any object that is interested in receiving messages (or events ) is called an Event Listener. Any object that generates these messages ( or events ) is called an Event Source
Event Delegation Model is based on four concepts:
The Event Classes
The Event Listeners
Explicit Event Enabling
Adapters
The modern approach to handling events is based on the delegation event model, which defines standard and consistent mechanisms to generate and process events. Its concept is quite simple: a source generates an event and sends it to one or more listeners. In this scheme, the listener simply waits until it receives an event. Once received, the listener processes the event and then returns. The advantage of this design is that the application logic that processes events is cleanly separated from the user interface logic that generates those events. A user interface element is able to "delegate" the processing of an event to a separate piece of code.
