package javax.swing.event;

import java.awt.AWTEvent;
import javax.swing.JInternalFrame;


An AWTEvent that adds support for
JInternalFrame objects as the event source.  This class has the
same event types as WindowEvent,
although different IDs are used.
Help on handling internal frame events
is in
How to Write an Internal Frame Listener,
a section in The Java Tutorial.


Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing.  As of 1.4, support for long term storage
of all JavaBeans™
has been added to the java.beans package. Please see XMLEncoder.
