java_GUI_监听事件关闭窗口_AWT

package Panel;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

//看做一个空间,但是不能单独存在
public class Panel_1 {
    public static void main(String[] args) {
        Frame frame = new Frame();
        Frame frame1 = new Frame();
//        布局的概念
        Panel panel = new Panel();
//        设置布局
        frame.setLayout(null);
//        坐标
        frame.setBounds(300,300,500,500);
        frame.setBackground(new Color(229, 45, 45));
//        设置panel坐标,相对于frame
        panel.setBounds(50,50,400,400);
        panel.setBackground(new Color(22, 234, 22));
//        frame.add();

        frame.add(panel);
        frame.setVisible(true);
//        监听事件
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
//                super.windowClosing(e);
                System.exit(0);
//                此为AWT的解决方式
            }
        });
