Posted by: kam Posted on: 2004-08-26 18:31 when you catch the value changed, then just pop up a specific menu ^.^ If you need code, then i think you need to wait until SAT or SUN, coz i don't think i have enough time now to write an example ... maybe you try it first, i try to write it as soon as possible ^.^

 private JPopupMenu ppmGroup = new JPopupMenu();
  private JMenuItem mnuNewGroup = new JMenuItem();
  private JMenuItem mnuEditGroup = new JMenuItem();
  private JMenuItem mnuDeleteGroup = new JMenuItem();

declare a Pop Up Menu, 以便我們可以彈出來...

menu 入面的action 自行寫啦...^.^


private void nodeAction()
   {
    jTree.addTreeSelectionListener(new TreeSelectionListener(){
    public void valueChanged(TreeSelectionEvent e)
    {
      DefaultMutableTreeNode selectedNode = (DefaultMutableTreeNode)jTree.getLastSelectedPathComponent();
      if (selectedNode == null)
      return;
      else
      ppmGroup.show(); //把menu 彈出來.............
    }
    }
    );
   }

這樣就ok啦....細節我就不多打了...^.^
