public class Event
extends java.lang.Object
The Event interface is used to provide contextual information about an event
to the handler processing the event. An object which implements the Event
interface is generally passed as the first parameter to an event handler.
More specific context information is passed to event handlers by deriving
additional interfaces from Event which contain information directly relating
to the type of event they accompany. These derived interfaces are also
implemented by the object passed to the event listener.
