Source Link

Document

Used to create an event when nodes have been changed, inserted, or removed, identifying the path to the parent of the modified items as a TreePath object.

Usage

From source file:TreeModelSupport.java

protected void fireTreeNodesChanged(Object source, Object[] path, int[] childIndices, Object[] children) {
    // Guaranteed to return a non-null array
    Object[] listeners = listenerList.getListenerList();
    TreeModelEvent e = null;//from w w w. j av  a  2s.c  o m
    // Process the listeners last to first, notifying
    // those that are interested in this event
    for (int i = listeners.length - 2; i >= 0; i -= 2) {
        if (listeners[i] == TreeModelListener.class) {
            // Lazily create the event:
            if (e == null)
                e = new TreeModelEvent(source, path, childIndices, children);
            ((TreeModelListener) listeners[i + 1]).treeNodesChanged(e);
        }
    }
