Method Detail

addTreeModelListener

public void addTreeModelListener(javax.swing.event.TreeModelListener l)

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

Specified by:

addTreeModelListener in interface javax.swing.tree.TreeModel

Parameters:

l - the listener to add

See Also:

removeTreeModelListener(javax.swing.event.TreeModelListener)

removeTreeModelListener

public void removeTreeModelListener(javax.swing.event.TreeModelListener l)

Removes a listener previously added with addTreeModelListener().

Specified by:

removeTreeModelListener in interface javax.swing.tree.TreeModel

Parameters:

l - the listener to remove

See Also:

addTreeModelListener(javax.swing.event.TreeModelListener)

getTreeModelListeners

public javax.swing.event.TreeModelListener[] getTreeModelListeners()

Returns an array of all the tree model listeners registered on this model.

Returns:

all of this model's TreeModelListeners or an empty array if no tree model listeners are currently registered

Since:

1.4

fireTreeNodesChanged

public void fireTreeNodesChanged(java.lang.Object source,
                                 java.lang.Object[] path,
                                 int[] childIndices,
                                 java.lang.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

fireTreeNodesInserted

public void fireTreeNodesInserted(java.lang.Object source,
                                  java.lang.Object[] path,
                                  int[] childIndices,
                                  java.lang.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

See Also:

EventListenerList

fireTreeNodesRemoved

public void fireTreeNodesRemoved(java.lang.Object source,
                                 java.lang.Object[] path,
                                 int[] childIndices,
                                 java.lang.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

See Also:

EventListenerList

fireTreeStructureChanged

public void fireTreeStructureChanged(java.lang.Object source,
                                     java.lang.Object[] path,
                                     int[] childIndices,
                                     java.lang.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 the tree model has changed

path - the path to the root node

childIndices - the indices of the affected elements

children - the affected elements

See Also:

EventListenerList

fireTreeStructureChanged

public void fireTreeStructureChanged(java.lang.Object source,
                                     javax.swing.tree.TreePath path)

getListeners

public java.util.EventListener[] getListeners(java.lang.Class listenerType)

Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultTreeModel m for its tree model listeners with the following code:

TreeModelListener[] tmls = (TreeModelListener[])(m.getListeners(TreeModelListener.class));

If no such listeners exist, this method returns an empty array.

Parameters:

listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener

Returns:

an array of all objects registered as FooListeners on this component, or an empty array if no such listeners have been added

Throws:

java.lang.ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener

Since:

1.3
