Provides interfaces and classes for dealing with different types of events
fired by AWT components. See the java.awt.AWTEvent
class for details on the AWT event model. Events are fired by event sources.
An event listener registers with an event source to receive notifications
about the events of a particular type. This package defines events and event
listeners, as well as event listener adapters, which are convenience classes
to make easier the process of writing event listeners.
