Java 鼠标事件监听WindowListener

1、点击时产生相应的动作事件

方法摘要
`void`	`windowActivated(WindowEvent e)` 将 Window 设置为活动 Window 时调用。
`void`	`windowClosed(WindowEvent e)` 因对窗口调用 dispose 而将其关闭时调用。
`void`	`windowClosing(WindowEvent e)` 用户试图从窗口的系统菜单中关闭窗口时调用。
`void`	`windowDeactivated(WindowEvent e)` 当 Window 不再是活动 Window 时调用。
`void`	`windowDeiconified(WindowEvent e)` 窗口从最小化状态变为正常状态时调用。
`void`	`windowIconified(WindowEvent e)` 窗口从正常状态变为最小化状态时调用。
`void`	`windowOpened(WindowEvent e)` 窗口首次变为可见时调用。

 2 {
 3     public static void main(String[] args) {
 4         TestWindowEvent frame = new TestWindowEvent();
 5         frame.setSize(500, 300);
 6         frame.addWindowListener(new MyWindowListener());
 7         frame.setVisible(true);
 8     }

10 class MyWindowListener implements WindowListener
11 {
12     @Override
13     public void windowOpened(WindowEvent e) {    
14     }
15     //点击窗口上面的叉叉的时候调用
16     @Override
17     public void windowClosing(WindowEvent e) {
18         System.out.println("world");
19         //程序退出的方法
20         System.exit(0);
21     }
22     //调用dispose方法的时候
23     @Override
24     public void windowClosed(WindowEvent e)
25     {
26         System.out.println("hello");//掌握这一个就好了
27     }
28     @Override
29     public void windowIconified(WindowEvent e) {    
30     }
31     @Override
