GUI编程入门到游戏实战 P2: awt 介绍

package gui.awt;

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

public class PanelTest {
    public static void main(String[] args) {

        frame f1 = new frame("窗口 1");
        Panel p1 = new Panel();
        f1.setLayout(null);
        f1.setBounds(300,300,500,500);
        f1.setBackground(new Color(1,1,1));

        p1.setBounds(50,50,400,400);
        p1.setBackground(new Color(208, 37, 122));

        f1.add(p1);
        f1.setVisible(true);

        // 关闭窗口
        f1.addWindowListener(new WindowAdapter(){
            @Override
            public void windowClosing(WindowEvent e){
                System.exit(0);
            }
        });
    }
}

P5: 三种布局管理器

1. 流形布局 FlowLayout
2. 东西南北中
3. 表格布局

P7: 事件监听

package gui.actionlistener;

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class ActionListen {

    public static void main(String[] args) {

        frame f1 = new frame("start--stop");
        Button b1 = new Button("start");
        Button b2 = new Button("stop");
        
        b2.setActionCommand("这里可以自定义");
        MyMoniter mm = new MyMoniter();
        b1.addActionListener(mm);
        b2.addActionListener(mm);
        
        f1.add(b1,BorderLayout.EAST);
        f1.add(b2,BorderLayout.WEST);
        f1.pack();
        
        f1.setVisible(true);

        f1.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });

    }
}

class MyMoniter implements ActionListener{

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("msg===> "+e.getActionCommand());
    }
}
