 protected class JTree.AccessibleJTree extends JComponent.AccessibleJComponent implements AccessibleSelection, TreeSelectionListener, TreeModelListener, TreeExpansionListener This class implements accessibility support for theJTreeclass. 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.beanspackage. Please seeXMLEncoder.- See Also:

Method Detail- 
valueChangedpublic void valueChanged(TreeSelectionEvent e) Tree Selection Listener value change method. Used to fire the property change- Specified by:
- valueChangedin interface- TreeSelectionListener
- Parameters:
- e- ListSelectionEvent
 
 - 
fireVisibleDataPropertyChangepublic 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.
 - 
treeNodesChangedpublic void treeNodesChanged(TreeModelEvent e) Tree Model Node change notification.- Specified by:
- treeNodesChangedin interface- TreeModelListener
- Parameters:
- e- a Tree Model event
 
 - 
treeNodesInsertedpublic void treeNodesInserted(TreeModelEvent e) Tree Model Node change notification.- Specified by:
- treeNodesInsertedin interface- TreeModelListener
- Parameters:
- e- a Tree node insertion event
 
 - 
treeNodesRemovedpublic void treeNodesRemoved(TreeModelEvent e) Tree Model Node change notification.- Specified by:
- treeNodesRemovedin interface- TreeModelListener
- Parameters:
- e- a Tree node(s) removal event
 
 - 
treeStructureChangedpublic void treeStructureChanged(TreeModelEvent e) Tree Model structure change change notification.- Specified by:
- treeStructureChangedin interface- TreeModelListener
- Parameters:
- e- a Tree Model event
 
 -

- treeCollapsedin interface- TreeExpansionListener
- Parameters:
- e- a TreeExpansionEvent
 
 -

- getAccessibleRolein class- JComponent.AccessibleJComponent
- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
- AccessibleRole
 
 - 
getAccessibleAtpublic Accessible getAccessibleAt(Point p) Returns theAccessiblechild, if one exists, contained at the local coordinatePoint. Otherwise returnsnull.- Specified by:
- getAccessibleAtin interface- AccessibleComponent
- Overrides:
- getAccessibleAtin class- Container.AccessibleAWTContainer
- Parameters:
- p- point in local coordinates of this- Accessible
- Returns:
- the Accessible, if it exists, at the specified location; elsenull
 
 - 
getAccessibleChildrenCountpublic int getAccessibleChildrenCount() Returns the number of top-level children nodes of this JTree. Each of these nodes may in turn have children nodes.- Overrides:
- getAccessibleChildrenCountin class- JComponent.AccessibleJComponent
- Returns:
- the number of accessible children nodes in the tree.
 
 - 
getAccessibleChildpublic Accessible getAccessibleChild(int i) Return the nth Accessible child of the object.- Overrides:
- getAccessibleChildin class- JComponent.AccessibleJComponent
- Parameters:
- i- zero-based index of child
- Returns:
- the nth Accessible child of the object
- See Also:
- AccessibleContext.getAccessibleChildrenCount()
 
 - 
getAccessibleIndexInParentpublic int getAccessibleIndexInParent() Get the index of this object in its accessible parent.- Overrides:

- the index of this object in its parent. Since a JTree top-level object does not have an accessible parent.
- See Also:
- Component.AccessibleAWTComponent.getAccessibleParent()
 
 - 
getAccessibleSelectionpublic AccessibleSelection getAccessibleSelection() Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.- Overrides:
- getAccessibleSelectionin class- AccessibleContext
- Returns:
- this object
- See Also:
- AccessibleSelection
 
 - 
getAccessibleSelectionCountpublic int getAccessibleSelectionCount() Returns the number of items currently selected. If no items are selected, the return value will be 0.- Specified by:

- See Also:
- AccessibleContext.getAccessibleChild(int)
 
 - 
addAccessibleSelectionpublic void addAccessibleSelection(int i) Adds the specified selected item in the object to the object's selection.
