GUI编程!

组件:

窗口
弹窗
面板
文本框
列表框
按钮
图片
监听事件
鼠标事件
键盘事件

1.简介

GUI的核心技术:Swing AWT

不流行的原因

1.因为页面不美观
2.需要jre环境!

2.AWT

2.1AWT介绍

1.包含了很多类和接口!GUI!

2.元素:窗口,按钮,文本框

3.java.awt

2.2组件和容器

1.Frame

package com.Su.lesson01;

import java.awt.*;

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

        //Frame对象,jdk
        Frame frame = new Frame("我的一个java图形窗口");

        //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(20, 234, 38));

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

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

问题:发现窗口关闭不掉,停止java运行

package com.Su.lesson01;

import java.awt.*;

public class TestFrame01 {
    public static void main(String[] args) {
        //展示多个窗口

        MyFrame myFrame1 = new MyFrame(100,100,200,200,Color.cyan);
        MyFrame myFrame2 = new MyFrame(300,300,200,200,Color.yellow);
        MyFrame myFrame3 = new MyFrame(100,100,200,200,Color.pink);
        MyFrame myFrame4 = new MyFrame(300,300,200,200,Color.magenta);
    }
}

class MyFrame extends Frame{
    static int id = 0;//可能存在多个窗口,我们需要一个计数器

    public MyFrame(int x,int y,int w,int h,Color color){
        super("MyFrame"+(++id));
        setBackground(color);
        setBounds(x,y,w,h);
        setVisible(true);
    }
}

2.面板panel

解决了关闭事件!

package com.Su.lesson01;

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

/**
 * panel是一个面板可以看成一个空间,但是不能单独存在
 */
public class TestPanel {
    public static void main(String[] args) {
        Frame frame = new Frame();
        //布局
        Panel panel = new Panel();

        //设置布局
        frame.setLayout(null);

        //坐标
        frame.setBounds(300,300,500,500);
        frame.setBackground(new Color(20, 234, 38));

        //panel设置坐标,相对于frame
        panel.setBounds(50,50,400,400);
        panel.setBackground(new Color(7, 101, 7, 253));

        //frame.add(panel)
        frame.add(panel);

        frame.setVisible(true);

        //监听事件,监听关闭窗口事件System.exit(0)
        //适配器模式 :
        frame.addWindowListener(new WindowAdapter() {
            //点击关闭的时候要做的事情
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
            //结束程序
        });
    }
}

2.3.布局管理系统

流式布局

package com.Su.lesson01;

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

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

        //按钮组件
        Button button1 = new Button("button1");
        Button button2 = new Button("button2");
        Button button3 = new Button("button3");

        //设计为流式布局
        //frame.setLayout(new FlowLayout());居中
        //frame.setLayout(new FlowLayout(FlowLayout.LEFT));左对齐
        frame.setLayout(new FlowLayout(FlowLayout.RIGHT));//右对齐

        frame.setSize(200,200);

        //添加按钮
        frame.add(button1);
        frame.add(button2);
        frame.add(button3);

        frame.setVisible(true);

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

东西南北中

package com.Su.lesson01;

import java.awt.*;

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

        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(500,500);
        frame.setVisible(true);
    }
}

表格布局

package com.Su.lesson01;

import java.awt.*;

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

        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.pack();
        frame.setSize(500,500);
        frame.setVisible(true);

    }
}

布局练习

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-Zi8PPsM9-1629811816159)(I:\JavaScript自学笔记\images\image-20210823102306111.png)]

代码

package com.Su.lesson01;

import java.awt.*;

public class classTest {

    public static void main(String[] args) {
        Frame frame = new Frame("课堂练习");
        frame.setVisible(true);
        frame.setLayout(new GridLayout(2,1));
        frame.setSize(300,400);
        frame.setLocation(400,300);

        Panel p1 = new Panel();
        Panel p2 = new Panel();
        Panel p3 = new Panel();
        Panel p4 = new Panel();

        p1.setLayout(new BorderLayout(0,0));
        p1.setBounds(0,0,300,200);
        p1.add(new Button("East-1"),BorderLayout.EAST);
        p1.add(p2,BorderLayout.CENTER);
        p1.add(new Button("West-1"),BorderLayout.WEST);

        p2.setLayout(new GridLayout(2,1));
        p2.add(new Button("Center-1"));
        p2.add(new Button("Center-2"));

        p3.setLayout(new BorderLayout(0,0));
        p3.setBounds(0,200,300,200);
        p3.add(new Button("East-2"),BorderLayout.EAST);
        p3.add(p4,BorderLayout.CENTER);
        p3.add(new Button("West-2"),BorderLayout.WEST);

        p4.setLayout(new GridLayout(2,2));
        p4.add(new Button("Center-3"));
        p4.add(new Button("Center-4"));
        p4.add(new Button("Center-5"));
        p4.add(new Button("Center-6"));

        frame.add(p1);
        frame.add(p3);
    }
}

总结

1.Frame是一个顶级窗口

2.panel无法单独显示,必须添加到某个容器中

3.布局管理器

1.流式

2.东西南北中

3.表格

4.大小,定位,背景颜色,可见性,监听!

2.4.事件监听

事件监听:当某个事情发生的时候,干什么?

package com.Su.lesson02;

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 TestAction {
    public static void main(String[] args) {
        //按下按钮会触发生什么
        Frame frame = new Frame();
        Button button = new Button();

        //因为addActionListener需要一个ActionListener,所以我们需要构造出一个ActionListener
        MyActionListener myActionListener = new MyActionListener();
        button.addActionListener(myActionListener);
        //文本框

        windClosing(frame);
        frame.add(button,BorderLayout.CENTER);
        frame.pack();
        frame.setVisible(true);
    }

    //关闭窗口事件
    public static void windClosing(Frame frame){
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }
}

//事件监听!
class MyActionListener implements ActionListener{

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("苏旭大帅逼!");
    }
}

多个按钮,共享一个事件

package com.Su.lesson02;

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 TestActionEven {
    public static void main(String[] args) {
        //两个按钮事件同一个监听
        //开始按钮      停止按钮
        Frame frame = new Frame("开始-停止");
        Button button = new Button("start");
        Button button1 = new Button("stop");

        //可以显示的定义的触发会返回的命令,如果不显示定义则会走默认的值
        //可以多个按钮只写一个监听类
        button1.setActionCommand("button1-stop");

        MyMonitor myMonitor = new MyMonitor();
        button.addActionListener(myMonitor);
        button1.addActionListener(myMonitor);

        frame.add(button,BorderLayout.SOUTH);
        frame.add(button1,BorderLayout.NORTH);

        windClosing(frame);
        frame.setVisible(true);
        frame.pack();
    }
    public static void windClosing(Frame frame){
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }
}

class MyMonitor implements ActionListener{

    @Override
    public void actionPerformed(ActionEvent e) {
        //获得按钮的信息
        System.out.println("按钮被点击了:msg"+e.getActionCommand());
    }
}

2.5.输入框TextField监听

package com.Su.lesson02;

import javax.xml.soap.Text;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class TestText01 {
    public static void main(String[] args) {
        //启动!
        new MyFrame();
    }
}
class MyFrame extends Frame {
    public MyFrame(){
        TextField textField = new TextField();
        add(textField);

        //监听文本框输入的内容
        MyActionListener2 myActionListener2 = new MyActionListener2();
        //按下Enter,就会触发这个输入框的事件
        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,返回了一个对象
        System.out.println(field.getText());//获得输入框的文本
        field.setText("");
    }
}

2.6.简单计算器,组和+内部类回顾复习!

opp原则:组和大于继承

class A extends B{
    //这是继承
}
class A{
    public B b;
    这是组和
}

package com.Su.lesson02;

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

/**

 * 简易计算器
   */
   public class TestCalc {
   public static void main(String[] args) {
       Calclator calclator = new Calclator();
   }
   }
   class Calclator extends Frame{
   public Calclator(){

       //三个文本框
       TextField number1 = new TextField(10);//字符数
       TextField number2 = new TextField(10);//字符数
       TextField number3 = new TextField(20);//字符数

       //1个按钮
       Button button = new Button("=");

       button.addActionListener(new MyCalclatorListener(number1,number2,number3));

       //一个标签
       Label label = new Label("+");

       //布局
       setLayout(new FlowLayout());

       add(number1);
       add(label);
       add(number2);
       add(button);
       add(number3);

       pack();
       setVisible(true);

   }
   }

//监听器类
class MyCalclatorListener implements ActionListener{

    //获取三个变量
    private TextField number1,number2,number3;

    public MyCalclatorListener(TextField number1, TextField number2, TextField number3) {
        this.number1 = number1;
        this.number2 = number2;
        this.number3 = number3;
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        //1.获得加数和被加数

        int n1 = Integer.parseInt(number1.getText());
        int n2 = Integer.parseInt(number2.getText());

        //2.将这个值加法运算后放到第三个框

        number3.setText(""+(n1+n2));

        //3.清除前两个框

        number1.setText("");
        number2.setText("");
    }
}

完全改造成面向对象

package com.Su.lesson02;

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

public class TestText02 {
    public static void main(String[] args) {
        new CesiumMath().Addition();
    }
}

class CesiumMath extends Frame {
    TextField num1,num2,num3;

    public void Addition(){
        num1 = new TextField(10);//字符数
        num2 = new TextField(10);//字符数
        num3 = new TextField(20);//字符数

        Button button = new Button("=");

        button.addActionListener(new MyCesiumMathListener(this));

        Label label = new Label("+");

        setLayout(new FlowLayout());

        add(num1);
        add(label);
        add(num2);
        add(button);
        add(num3);

        pack();
        setVisible(true);
    }
}

class MyCesiumMathListener implements ActionListener{

    CesiumMath cesiumMath = null;

    public MyCesiumMathListener(CesiumMath cesiumMath){
        this.cesiumMath = cesiumMath ;
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        int n1 = Integer.parseInt(cesiumMath.num1.getText());
        int n2 = Integer.parseInt(cesiumMath.num2.getText());

        //2.将这个值加法运算后放到第三个框

        cesiumMath.num3.setText(""+(n1+n2));

        //3.清除前两个框

        cesiumMath.num1.setText("");
        cesiumMath.num2.setText("");
    }
}

更好的包装

内部类(内部类可以畅通无阻的访问外部类)

package com.Su.lesson02;

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

public class TestText02 {
    public static void main(String[] args) {
        new CesiumMath().Addition();
    }
}

class CesiumMath extends Frame {
    TextField num1,num2,num3;

    public void Addition(){
        num1 = new TextField(10);//字符数
        num2 = new TextField(10);//字符数
        num3 = new TextField(20);//字符数

        Button button = new Button("=");

        button.addActionListener(new MyCesiumMathListener());

        Label label = new Label("+");

        setLayout(new FlowLayout());

        add(num1);
        add(label);
        add(num2);
        add(button);
        add(num3);

        pack();
        setVisible(true);
    }
    private class MyCesiumMathListener implements ActionListener{

        @Override
        public void actionPerformed(ActionEvent e) {
            int n1 = Integer.parseInt(num1.getText());
            int n2 = Integer.parseInt(num2.getText());

            //2.将这个值加法运算后放到第三个框

            num3.setText(""+(n1+n2));

            //3.清除前两个框

            num1.setText("");
            num2.setText("");
        }
}
}

2.7.画笔

package com.Su.lesson03;

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

public class TestPaint {
    public static void main(String[] args) {
        new MyPaint().localFrameP();
    }
}

class MyPaint extends Frame {
    public void localFrameP(){
        setBounds(200,200,800,800);
        setVisible(true);
        addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }

    //画笔
    @Override
    public void paint(Graphics g){
        //画笔需要有颜色
        //画笔需要画画
        g.setColor(Color.red);
        g.draw3DRect(100,100,100,100,true);
    }
}

2.8鼠标监听

目的:想要实现鼠标的画画

package com.Su.lesson03;

import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.util.ArrayList;
import java.util.Iterator;

public class TestMouseListener {
    public static void main(String[] args) {
        new MyFrame("画图");
    }
}

class MyFrame extends Frame{
    //画画需要画笔,监听鼠标当前的位置,需要集合存储这个点

    ArrayList points;

    public MyFrame(String title){
        super(title);
        setBounds(200,200,300,300);

        //存鼠标监听的点
        points = new ArrayList<>();
        //鼠标监听器,正对这个窗口
        this.addMouseListener(new MyMouseListener());

        setVisible(true);

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

    @Override
    public void paint(Graphics g) {
        //需要监听窗口
        Iterator iterator = points.iterator();
        while(iterator.hasNext()){
            Point point = (Point) iterator.next();
            g.setColor(Color.blue);
            g.fillOval(point.x,point.y,10,10);

        }
    }
    //添加一个点到界面上去
    public void addPaint(Point point){
        points.add(point);
    }


    //适配器模式
    private class MyMouseListener extends MouseAdapter{
        //鼠标    按下.弹起.按住不放

        @Override
        public void mousePressed(MouseEvent e) {
            MyFrame myFrame = (MyFrame) e.getSource();
            //点击的时候就会在界面上产生一个点!
