如何在Java中仅当我的框架在屏幕上消失时进行操作？

import java.awt.*;
import java.awt.event.*;

public class MyFrame extends Frame implements WindowListener {
    
    public MyFrame() {
        // 设置窗口标题
        setTitle("My Frame");
        
        // 添加窗口监听器
        addWindowListener(this);
    }
    
    // 实现WindowListener接口的方法
    public void windowOpened(WindowEvent e) {}
    
    public void windowClosing(WindowEvent e) {
        // 在窗口关闭时执行操作
        // 这里可以添加你的代码逻辑
        
        // 关闭窗口
        dispose();
    }
    
    public void windowClosed(WindowEvent e) {}
    
    public void windowIconified(WindowEvent e) {}
    
    public void windowDeiconified(WindowEvent e) {}
    
    public void windowActivated(WindowEvent e) {}
    
    public void windowDeactivated(WindowEvent e) {}
    
    public static void main(String[] args) {
        MyFrame frame = new MyFrame();
        
        // 设置窗口大小
        frame.setSize(300, 200);
        
        // 显示窗口
        frame.setVisible(true);
    }
}
