protected class JTree.AccessibleJTree extends JComponent.AccessibleJComponent implements AccessibleSelection, TreeSelectionListener, TreeModelListener, TreeExpansionListener
JTree
class. It provides an implementation of the Java Accessibility API appropriate to tree user-interface elements. 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
