AUI布局管理

package com.guoguo.lesson01;

import sun.font.TrueTypeFont;

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

//panel可以看成一个空间，不能单独存在
public class Testpanel {
    public static void main(String[] args) {
        frame frame = 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(2, 232, 191));
        //panel也可设置，相对于frame
        //panel坐标设置
        panel.setBounds(50,50,400,400);
        panel.setBackground(new Color(177,17,71));
        frame.add(panel);
        frame.setVisible(true);
        //监听事件，监听窗口关闭System.exit()
        //适配器模式
        frame.addWindowListener(new WindowAdapter() {
            //窗口关闭，需要做的事情
            @Override
            public void windowClosing(WindowEvent e) {
                //结束程序
               System.exit(0);
            }
        });
    }
}

流式布局、东西南北中、表格布局，java中new用alt enter

流式布局

package com.guoguo.lesson01;

import java.awt.*;

public class TestFlowLayerout {
    public static void main(String[] args) {
        frame frame = new frame();
        //组件;按钮
        Button button1 = new Button("button1");
        Button button2 = new Button("button2");
        Button button3 = new Button("button3");
        //设置为流式布局
        frame.setLayout(new FlowLayout());//默认居中
        frame.setLayout(new FlowLayout(FlowLayout.LEADING));//默认居中

        frame.setSize(200,200);
        frame.add(button1);
        frame.add(button2);
        frame.add(button3);
        frame.setVisible(true);







    }

东西南北中

package com.guoguo.lesson01;

import java.awt.*;

public class TestBorderlayout {
    public static void main(String[] args) {
        frame frame = new frame();

        Button east = new Button("East");
        Button west = new Button("West");
        Button south = new Button("South");
        Button north = new Button("North");
        Button center = new Button("Center");
        frame.add(east,BorderLayout.EAST);
        frame.add(west,BorderLayout.WEST);
        frame.add(south,BorderLayout.SOUTH);
        frame.add(north,BorderLayout.NORTH);
        frame.add(center,BorderLayout.CENTER);
        frame.setSize(500,200);
        frame.setVisible(true);

    }
}

表格grid，包括作业；

package com.guoguo.lesson01;

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

public class Exdemo {
    public static void main(String[] args) {
        //总frame窗口
        frame frame = new frame();
        frame.setSize(400,300);
        frame.setLocation(200,300);
        frame.setBackground(Color.BLACK);
        frame.setVisible(true);
        frame.setLayout(new GridLayout(2,1));
        //四个面板
        //上面
        Panel p1 = new Panel(new BorderLayout());
        Panel p2 = new Panel(new GridLayout(2,1));
        Panel p3 = new Panel(new BorderLayout());
        Panel p4 = new Panel(new GridLayout(2,2));
        p1.add(new Button("East-1"),BorderLayout.EAST);
        p1.add(new Button("West-1"),BorderLayout.WEST);
        p2.add(new Button("P2-BTN-1"));
        p2.add(new Button("P2-BTN-2"));
        p1.add(p2,BorderLayout.CENTER);
        //下面
        p3.add(new Button("East-2"),BorderLayout.EAST);
        p3.add(new Button("West-2"),BorderLayout.WEST);
        for (int i = 0; i < 4; i++) {
            p4.add(new Button("for-"+i));
        }
        p3.add(p4,BorderLayout.CENTER);
        frame.add(p1);
        frame.add(p3);
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }
}
