EventObject
Synopsis
EventObject
serves as the superclass for all event objects used by the event
model introduced in Java 1.1 for AWT and JavaBeans and also used by
Swing in Java 1.2. This class defines a generic type of event; it is
extended by the more specific event classes in the
java.awt
, java.awt.event
,
java.beans
, and
javax.swing.event
packages. The only common
feature shared by all events is a source object, which is the object
that, in some way, generated the event. The source object is passed
to the EventObject( )
constructor and is returned
by the getSource( )
method.
