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
-
valueChanged
public void valueChanged(TreeSelectionEvent e)
Tree Selection Listener value change method. Used to fire the property change- Specified by:
valueChangedin interfaceTreeSelectionListener- 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:
treeNodesChangedin interfaceTreeModelListener- Parameters:
e- a Tree Model event
-
treeNodesInserted
public void treeNodesInserted(TreeModelEvent e)
Tree Model Node change notification.- Specified by:
treeNodesInsertedin interfaceTreeModelListener- Parameters:
e- a Tree node insertion event
-
treeNodesRemoved
public void treeNodesRemoved(TreeModelEvent e)
Tree Model Node change notification.- Specified by:
treeNodesRemovedin interfaceTreeModelListener- Parameters:
e- a Tree node(s) removal event
-
treeStructureChanged
public void treeStructureChanged(TreeModelEvent e)
Tree Model structure change change notification.- Specified by:
treeStructureChangedin interfaceTreeModelListener- Parameters:
e- a Tree Model event
-
treeCollapsed
public void treeCollapsed(TreeExpansionEvent e)
Tree Collapsed notification.- Specified by:
treeCollapsedin interfaceTreeExpansionListener- Parameters:
e- a TreeExpansionEvent
-
treeExpanded
public void treeExpanded(TreeExpansionEvent e)
Tree Model Expansion notification.- Specified by:
treeExpandedin interfaceTreeExpansionListener- Parameters:
e- a Tree node insertion event
-
getAccessibleRole
public AccessibleRole getAccessibleRole()
Get the role of this object.- Overrides:
getAccessibleRolein classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
AccessibleRole
-
getAccessibleAt
public Accessible getAccessibleAt(Point p)
Returns theAccessiblechild, if one exists, contained at the local coordinatePoint. Otherwise returnsnull.- Specified by:
getAccessibleAtin interfaceAccessibleComponent- Overrides:
getAccessibleAtin classContainer.AccessibleAWTContainer- Parameters:
p- point in local coordinates of thisAccessible- Returns:
- the
Accessible, if it exists, at the specified location; elsenull
-
getAccessibleChildrenCount
public 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 classJComponent.AccessibleJComponent- Returns:
- the number of accessible children nodes in the tree.
-
getAccessibleChild
public Accessible getAccessibleChild(int i)
Return the nth Accessible child of the object.- Overrides:
getAccessibleChildin classJComponent.AccessibleJComponent- Parameters:
i- zero-based index of child- Returns:
- the nth Accessible child of the object
- See Also:
AccessibleContext.getAccessibleChildrenCount()
-
getAccessibleIndexInParent
public int getAccessibleIndexInParent()
Get the index of this object in its accessible parent.- Overrides:
getAccessibleIndexInParentin classComponent.AccessibleAWTComponent- Returns:

- See Also:
Component.AccessibleAWTComponent.getAccessibleParent()
-

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 classAccessibleContext- Returns:
- this object
- See Also:
AccessibleSelection
-
getAccessibleSelectionCount
public int getAccessibleSelectionCount()
Returns the number of items currently selected. If no items are selected, the return value will be 0.- Specified by:
getAccessibleSelectionCountin interfaceAccessibleSelection- Returns:

AccessibleContext.getAccessibleChild(int)
-
addAccessibleSelection
public void addAccessibleSelection(int i)
Adds the specified selected item in the object to the object's selection. If the object supports multiple selections, the specified item is added to any existing selection, otherwise it replaces any existing selection in the object. If the specified item is already selected, this method has no effect.- Specified by:
addAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selectable items- See Also:
AccessibleContext.getAccessibleChild(int)

clearAccessibleSelectionin interfaceAccessibleSelection
-
