Enclosing class:

JTree

protected class JTree.AccessibleJTree
extends JComponent.AccessibleJComponent
implements AccessibleSelection, TreeSelectionListener, TreeModelListener, TreeExpansionListener

This class implements accessibility support for the 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.

Constructor Detail

AccessibleJTree

public AccessibleJTree()

Method Detail

valueChanged

public void valueChanged(TreeSelectionEvent e)

Tree Selection Listener value change method. Used to fire the property change

Specified by:

valueChanged in interface TreeSelectionListener

Parameters:

e - ListSelectionEvent

fireVisibleDataPropertyChange

public void fireVisibleDataPropertyChange()

Fire a visible data property change notification. A 'visible' data property is one that represents something about the way the component appears on the display, where that appearance isn't bound to any other property. It notifies screen readers that the visual appearance of the component has changed, so they can notify the user.

treeNodesChanged

public void treeNodesChanged(TreeModelEvent e)

Tree Model Node change notification.

Specified by:

treeNodesChanged in interface TreeModelListener

Parameters:

e - a Tree Model event

treeNodesInserted

public void treeNodesInserted(TreeModelEvent e)

Tree Model Node change notification.

Specified by:

treeNodesInserted in interface TreeModelListener

Parameters:

e - a Tree node insertion event

treeNodesRemoved

public void treeNodesRemoved(TreeModelEvent e)

Tree Model Node change notification.

Specified by:

treeNodesRemoved in interface TreeModelListener

Parameters:

e - a Tree node(s) removal event

treeStructureChanged

public void treeStructureChanged(TreeModelEvent e)

Tree Model structure change change notification.

Specified by:

treeStructureChanged in interface TreeModelListener

Parameters:

e - a Tree Model event

treeCollapsed

public void treeCollapsed(TreeExpansionEvent e)

Tree Collapsed notification.

Specified by:

treeCollapsed in interface TreeExpansionListener

Parameters:

e - a TreeExpansionEvent
