jTree 问题

Question

如何用java 在树的结点上做右键事件?

Answer 1

tree.addTreeSelectionListener(new
         TreeSelectionListener()
         {
            public void valueChanged(TreeSelectionEvent event)
            {}
         });

Answer 2

用此方法：
tree.addTreeSelectionListener(new
         TreeSelectionListener()
         {
            public void valueChanged(TreeSelectionEvent event)
            {}
         });
只能做左键事件啊？
我想在节点上做右键菜单。

Answer 3

tree.addMouseListener( new MouseAdapter(){
public void mouseClicked( MouseEvent e ){
popupMenu.show(.....);
}
} );

Answer 4

用以下方法并不能将事件源精确到树的节点上噢，而是在整个树上
tree.addMouseListener( new MouseAdapter(){
public void mouseClicked( MouseEvent e ){
popupMenu.show(.....);
}
} );

Answer 5

jPopupMenu.setInvoker(jTreeWSA);
    jTreeWSA.add(jPopupMenu);
    jTreeWSA.addMouseListener(new java.awt.event.MouseAdapter() {
      public void mousePressed(MouseEvent e) {
        jTreeWSA_mousePressed(e);
      }
    });void jTreeWSA_mousePressed(MouseEvent e) {
    // jTabbedPane1.setSelectedComponent(jPanelDBAInfo);
    if (e.getModifiers() == Event.META_MASK) {
      jPopupMenu.show(jTreeWSA, e.getX(), e.getY());
    }
  }
选择的节点变化了valueChanged就触发：
tree.addTreeSelectionListener(new
TreeSelectionListener()
{
public void valueChanged(TreeSelectionEvent event)
{}
});TreePath path = jTreeWSA.getSelectionPath();得到当前选择的节点路径
