package javax.swing.event;

import java.util.EventObject;
import javax.swing.tree.TreePath;

An event used to identify a single path in a tree.  The source
returned by getSource will be an instance of JTree.

For further documentation and examples see
the following sections in The Java Tutorial:
How to Write a Tree Expansion Listener and
How to Write a Tree-Will-Expand Listener.

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.
