JPopupMenu

Question

我用JPopupMenu 定义了一个变量JPopupMenu2，JPopupMenu2.add(new   JMenuItem( "Delete"));
JPopupMenu2.add(new   JMenuItem( "Add"));JPopupMenu2出现后，我用鼠标点击，如何获取我点击的是那个Item？

Answer 1

JMenuItem menu1 = new JMenuItem( "Delete"));
JMenuItem menu2 = new JMenuItem( "Add"));JPopupMenu2.add(menu1);
JPopupMenu2.add(menu2);menu1.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
//delete处理
    }
});
menu2.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
//add处理
    }
});
