Frame(非JFrame)如何在按关闭按钮时关闭

来源：互联网发布：云计算架构师要学什么编辑：程序博客网时间：2024/05/01 01:50

如果是JFrame, 则调用这段代码即可frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

但是如果是Frame则应该如何关闭呢, 下面就介绍一种方法:

package cn.edu.practice.awt;

import java.awt.FlowLayout;

import java.awt.Frame;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class TestCloseFrame extends Frame{

/**
* @param args
*/
public static void main(String[] args) {

    TestCloseFrame tcf= new TestCloseFrame ();
    tcf.setLayout(new FlowLayout());
    tcf.setSize(500, 400);

tcf.addWindowListener(new TestWindowListener());

}

class TestWindowListener implements WindowListener{

public void windowActivated(WindowEvent e) {
// TODO Auto-generated method stub

}

public void windowClosed(WindowEvent e) { }

public void windowClosing(WindowEvent e) {
e.getWindow().dispose();

}

public void windowDeactivated(WindowEvent e) { }

public void windowDeiconified(WindowEvent e) { }

public void windowIconified(WindowEvent e) { }

public void windowOpened(WindowEvent e) { }

}
