• 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 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:

    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. 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()

    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
