GUI编程

1.简介

Gui的核心技术：Swing AWT

  //Fram对象
    Frame frame = new Frame("我的第一个java图像界面窗口");

    //需要设置可见性
    frame.setVisible(true);

    //设置窗口大小
    frame.setSize(400,400);

    //设置背景颜色
    frame.setBackground(new Color(52, 73, 179));

    //弹出的初始位置
    frame.setLocation(200,200);

    //设置大小固定
    frame.setResizable(false);
}

2.面板Panel

package com.lm.lesson01;

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

//Panel  可以看成一个空间。但是不可以单独存在。
public class TestPanel {
    public static void main(String[] args) {
        Frame frame = new Frame();
        Panel panel = new Panel();//布局的概念

        //设置布局
        frame.setLayout(null);
        //坐标
        frame.setBounds(300,300,500,500);
        frame.setBackground(new Color(118, 186, 17));


        //设置坐标相对于frame
        panel.setBounds(50,50,400,400);
        panel.setBackground(new Color(24, 57, 156));

        //
        frame.add(panel);

        frame.setVisible(true);


        //监听
        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);
            }
        });
    }
}

3.流式布局

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

        Frame frame = new Frame("TestBorderLayout");

        Button east = new Button("East");
        Button west = new Button("west");
        Button south = new Button("Sout");
        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.setVisible(true);
        frame.setSize(200,200);

public class TestGridLayout {
    public static void main(String[] args) {
        Frame frame = new Frame("TestBorderLayout");

        Button btn1 = new Button("btn1");
        Button btn2 = new Button("btn2");
        Button btn3 = new Button("btn3");
        Button btn4 = new Button("btn4");
        Button btn5 = new Button("btn5");
        Button btn6 = new Button("btn6");

        frame.setLayout(new GridLayout(3,2));
        frame.add(btn1);
        frame.add(btn2);
        frame.add(btn3);
        frame.add(btn4);
        frame.add(btn5);
        frame.add(btn6);
		frame.setVisible(true);
        frame.pack();
    }

4.事件监听

public class TestActionTwo {
    public static void main(String[] args) {
        //两个按钮实现同一个监听
        Frame frame = new Frame("开始-停止");
        Button button1 = new Button("开始");
        Button button2 = new Button("停止");
        MyMonitor myMonitor = new MyMonitor();
        button1.addActionListener(myMonitor);
        button2.addActionListener(myMonitor);
        frame.add(button1,BorderLayout.NORTH);
        frame.add(button2,BorderLayout.SOUTH);
        frame.pack();
        frame.setVisible(true);
    }
}
class MyMonitor implements ActionListener{
    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("按钮点击了=>"+e.getActionCommand());
    }

5.输入框TextFiled 监听

public class TestText01 {
    public static void main(String[] args) {
        //main只管启动
        new MyFrame();
    }
}

class  MyFrame extends Frame{
    public MyFrame(){
        TextField textField = new TextField();
        add(textField);

        //监听文本输入的文字
        MyActionListener2 myActionListener2 = new MyActionListener2();
        //按下回车输入
        textField.addActionListener(myActionListener2);

        //设置替换编码
        textField.setEchoChar('*');

        setVisible(true);
        pack();

    }
}
class MyActionListener2 implements ActionListener{
    @Override
    public void actionPerformed(ActionEvent e) {

        TextField field=(TextField) e.getSource();//获得一些资源
        System.out.println(field.getText());//获得输入框的文本
        field.setText("");

6.画笔

class MyPaint extends Frame{

    public void loadFrame(){
        setVisible(true);
        setBounds(200,200,400,400);
    }

    @Override
    public void paint(Graphics g){
     //画笔的颜色
        g.setColor(new Color(145, 198, 13));
        g.drawOval(100,100,100,100);
        g.fillOval(200,200,200,200);

        g.setColor(Color.red);
        g.fillRect(150,150,200,200);

7.鼠标监听

目的：实现鼠标画画

8.窗口监听

9.键盘监听
