fireTreeNodesChanged

protected 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

EventListenerList

fireTreeNodesInserted

protected 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
