请问Swing中的JTree控件如何让监听一个子叶的鼠标事件？

Question

final JTree tree = new JTree();
MouseListener ml = new MouseAdapter()
{
   public void mouseClicked(MouseEvent event)
   {
            int selRow = tree.getRowForLocation(event.getX(), event.getY());
            TreePath selPath = tree.getPathForLocation(event.getX(), event.getY());
                
            if(selRow != -1) 
            {
                DefaultMuteNode node = (DefaultMuteNode)tree.getLastSelectedPathComponent();             }   }// of public void mousePressed(MouseEvent event)
}; // mouseListener defined
tree.addMouseListener(ml);

import ......;
final JTree tree = new JTree();
MouseListener ml = new MouseAdapter()
{
   public void mouseClicked(MouseEvent event)
   {
            int selRow = tree.getRowForLocation(event.getX(), event.getY());
            TreePath selPath = tree.getPathForLocation(event.getX(), event.getY());
                
            if(selRow != -1) 
            {
                DefaultMuteNode node = (DefaultMuteNode)tree.getLastSelectedPathComponent();
                if (node.isLeaf())
                {
                    //event deal operation.
                 }
             }   }// of public void mousePressed(MouseEvent event)
}; // mouseListener defined
tree.addMouseListener(ml);
