Question

I got an example of JPanel from the Oracle tutorials I see it uses a default method to close the window

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

我想的是,在点击了近东时关闭窗口,以触发另一种方法。

我如何能够这样做?

Answer 1

frame.addWindowListener(new WindowAdapter() {
  public void windowClosing(WindowEvent e) {
    //do something
  }
});

Answer 2

当你试图终止“游轮”或“青少年”方案时,该法典将予以执行。

Runtime.getRuntime().addShutdownHook(new Thread()
{
    @Override
    public void run()
    {
        //code goes here
    }
});
