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.

Method Details
-
valueChanged
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
Tree Model Node change notification.- Specified by:
treeNodesChangedin interfaceTreeModelListener- Parameters:
e- a Tree Model event
-
treeNodesInserted
Tree Model Node change notification.- Specified by:
treeNodesInsertedin interfaceTreeModelListener- Parameters:
e- a Tree node insertion event
-
treeNodesRemoved
Tree Model Node change notification.- Specified by:
treeNodesRemovedin interfaceTreeModelListener- Parameters:
e- a Tree node(s) removal event
-
treeStructureChanged
Tree Model structure change change notification.- Specified by:
treeStructureChangedin interfaceTreeModelListener- Parameters:
e- a Tree Model event
-
treeCollapsed
Tree Collapsed notification.- Specified by:
treeCollapsedin interfaceTreeExpansionListener- Parameters:
e- a TreeExpansionEvent
-
treeExpanded
Tree Model Expansion notification.- Specified by:
treeExpandedin interfaceTreeExpansionListener- Parameters:
e- a Tree node insertion event
-
getAccessibleRole
Get the role of this object.- Overrides:
getAccessibleRolein classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
-
getAccessibleAt
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
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:
-
getAccessibleIndexInParent
public int getAccessibleIndexInParent()Get the index of this object in its accessible parent.- Overrides:
getAccessibleIndexInParentin classComponent.AccessibleAWTComponent- Returns:
- the index of this object in its parent. Since a JTree top-level object does not have an accessible parent.
- See Also:
-
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 classAccessibleContext- Returns:
- this object
- See Also:
-
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:
- the number of items currently selected.
-
getAccessibleSelection
Returns an Accessible representing the specified selected item in the object. If there isn't a selection, or there are fewer items selected than the integer passed in, the return value will be null.- Specified by:
getAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selected items- Returns:
- an Accessible containing the selected item
- See Also:
-
isAccessibleChildSelected
public boolean isAccessibleChildSelected(int i) Returns true if the current child of this object is selected.- Specified by:
isAccessibleChildSelectedin interfaceAccessibleSelection- Parameters:
i- the zero-based index of the child in this Accessible object.- Returns:
trueif the current child of this object is selected; elsefalse- See Also:
-
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:
-
removeAccessibleSelection
public void removeAccessibleSelection(int i) Removes the specified selected item in the object from the object's selection. If the specified item isn't currently selected, this method has no effect.- Specified by:
removeAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selectable items- See Also:
-
clearAccessibleSelection
public void clearAccessibleSelection()Clears the selection in the object, so that nothing in the object is selected.- Specified by:
clearAccessibleSelectionin interfaceAccessibleSelection
-
selectAllAccessibleSelection
public void selectAllAccessibleSelection()Causes every selected item in the object to be selected if the object supports multiple selections.- Specified by:
selectAllAccessibleSelectionin interfaceAccessibleSelection
