Disabled: no SafeJ information.

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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

Constructor Detail

JTree.AccessibleJTree

public JTree.AccessibleJTree()
Class is disabled.

Method Detail

valueChanged

public void valueChanged(TreeSelectionEvent e)
Class is disabled.

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()
Class is disabled.

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)
Class is disabled.

Tree Model Node change notification.

Specified by:
treeNodesChanged in interface TreeModelListener
Parameters:
e - a Tree Model event

treeNodesInserted

public void treeNodesInserted(TreeModelEvent e)
Class is disabled.

Tree Model Node change notification.

Specified by:
treeNodesInserted in interface TreeModelListener
Parameters:
e - a Tree node insertion event

treeNodesRemoved

public void treeNodesRemoved(TreeModelEvent e)
Class is disabled.

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)
Class is disabled.

Tree Model structure change change notification.

Specified by:
treeStructureChanged in interface TreeModelListener
Parameters:
e - a Tree Model event

treeCollapsed

public void treeCollapsed(TreeExpansionEvent e)
Class is disabled.

Tree Collapsed notification.

Specified by:
treeCollapsed in interface TreeExpansionListener
Parameters:
e - a TreeExpansionEvent

treeExpanded

public void treeExpanded(TreeExpansionEvent e)
Class is disabled.

Tree Model Expansion notification.

Specified by:
treeExpanded in interface TreeExpansionListener
Parameters:
e - a Tree node insertion event

getAccessibleRole

public AccessibleRole getAccessibleRole()
Class is disabled.

Get the role of this object.

Overrides:
getAccessibleRole in class JComponent.AccessibleJComponent
Returns:
an instance of AccessibleRole describing the role of the object
See Also:
AccessibleRole

getAccessibleAt

public Accessible getAccessibleAt(Point p)
Class is disabled.

Returns the Accessible child, if one exists, contained at the local coordinate Point. Otherwise returns null.

Specified by:
getAccessibleAt in interface AccessibleComponent
Overrides:
getAccessibleAt in class Container.AccessibleAWTContainer
Parameters:
p - point in local coordinates of this Accessible
Returns:
the Accessible, if it exists, at the specified location; else null

getAccessibleChildrenCount

public int getAccessibleChildrenCount()
Class is disabled.

Returns the number of top-level children nodes of this JTree. Each of these nodes may in turn have children nodes.

Overrides:
getAccessibleChildrenCount in class JComponent.AccessibleJComponent
Returns:
the number of accessible children nodes in the tree.

getAccessibleChild

public Accessible getAccessibleChild(int i)
Class is disabled.

Return the nth Accessible child of the object.

Overrides:
getAccessibleChild in class JComponent.AccessibleJComponent
Parameters:
i - zero-based index of child
Returns:
the nth Accessible child of the object
See Also:
AccessibleContext.getAccessibleChildrenCount()

getAccessibleIndexInParent

public int getAccessibleIndexInParent()
Class is disabled.

Get the index of this object in its accessible parent.

Overrides:
getAccessibleIndexInParent in class Component.AccessibleAWTComponent
Returns:
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()

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()
Class is disabled.

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:
getAccessibleSelection in class AccessibleContext
Returns:
