Constructor Detail

JTree.AccessibleJTree

public JTree.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 that it 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

treeExpanded

public void treeExpanded(TreeExpansionEvent e)

Tree Model Expansion notification.

Specified by:

treeExpanded in interface TreeExpansionListener

Parameters:

e - a Tree node insertion event

getAccessibleRole

public AccessibleRole getAccessibleRole()

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)

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

Overrides:

getAccessibleAt in class JComponent.AccessibleJComponent

Parameters:

p - point in local coordinates of the this Accessible

Returns:

the Accessible, if it exists, at the specified location; else null

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:

getAccessibleChildrenCount in class JComponent.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:

getAccessibleChild in class JComponent.AccessibleJComponent

Parameters:

i - zero-based index of child

Returns:

the nth Accessible child of the object

getAccessibleIndexInParent

public int getAccessibleIndexInParent()

Get the index of this object in its accessible parent.

Overrides:

getAccessibleIndexInParent in class JComponent.AccessibleJComponent

Returns:

the index of this object in its parent. Since a JTree top-level object does not have an accessible parent.

See Also:

JComponent.AccessibleJComponent.getAccessibleParent()

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()

Description copied from class: AccessibleContext

Get the AccessibleSelection associated with this object which allows its Accessible children to be selected.

Overrides:

getAccessibleSelection in class AccessibleContext

Tags copied from class: AccessibleContext

Returns:

AccessibleSelection if supported by object; else return null

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:

getAccessibleSelectionCount in interface AccessibleSelection

Returns:

the number of items currently selected.

getAccessibleSelection

public Accessible getAccessibleSelection(int i)

Returns an Accessible representing the specified selected item in the object. If there isn't a selection, or there are fewer items selcted than the integer passed in, the return value will be null.

Specified by:

getAccessibleSelection in interface AccessibleSelection

Parameters:

i - the zero-based index of selected items

Returns:
