Method Detail

addTreeModelListener

public void addTreeModelListener(TreeModelListener l)

Adds a listener for the TreeModelEvent posted after the tree changes.

Specified by:

addTreeModelListener in interface TreeModel

Parameters:

l - the listener to add

See Also:

removeTreeModelListener(javax.swing.event.TreeModelListener)

removeTreeModelListener

public void removeTreeModelListener(TreeModelListener l)

Removes a listener previously added with addTreeModelListener().

Specified by:

removeTreeModelListener in interface TreeModel

Parameters:

l - the listener to remove

addTreeModelListener(javax.swing.event.TreeModelListener)

fireTreeNodesRemoved

protected void fireTreeNodesRemoved(Object source,
                                    TreePath path,
                                    int[] childIndices,
                                    Object... children)

Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

Parameters:

source - the node where elements are being removed

path - the path to the root node

childIndices - the indices of the removed elements

children - the removed elements

EventListenerList

fireTreeNodesInserted

protected void fireTreeNodesInserted(Object source,
                                     TreePath path,
                                     int[] childIndices,
                                     Object... children)

Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

Parameters:

source - the node where new elements are being inserted

path - the path to the root node

childIndices - the indices of the new elements

children - the new elements

EventListenerList

fireTreeNodesChanged

protected void fireTreeNodesChanged(Object source,
                                    TreePath path,
                                    int[] childIndices,
                                    Object... children)

Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

Parameters:

source - the node being changed

path - the path to the root node

childIndices - the indices of the changed elements

children - the changed elements

See Also:

EventListenerList

fireTreeStructureChanged

protected void fireTreeStructureChanged(Object source,
                                        TreePath path)

Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

Parameters:

source - the node where the tree model has changed

path - the path to the root node

getListeners

public TreeModelListener[] getListeners()

Get a list of all tree listeners, which listen to this model changes.

Returns:

a possible empty list.
