GUI编程

1、简介

GUI的核心技术：Swing AWT（即将淘汰）

需要jre环境
界面不美观

为什么要学习？

可以写出自己心中想要的一些小工具
工作时候，也可能需要维护到Swing界面，概率极小
了解MVC架构，了解监听！

2、AWT

2.1 AWT介绍

包含了很多类和接口，用于图形用户界面编程。
元素：窗口、按钮、文本框
java.awt.*
组件（Component）

基本组件

button
TextArea
Label
...

容器（Container）

Window

Frame
Dialog（弹窗）

Panel(面板)

Applet

2.2组件和容器

frame

package com.gui;

import java.awt.*;

//GUI的第一个界面
public class TestFrame {
    public static void main(String[] args) {
        Frame frame = new Frame("第一个JAVA图像界面窗口");
        //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(180, 48, 48));
        //窗口弹出的初始位置
        frame.setLocation(200,200);
        //设置窗口大小固定
        frame.setResizable(false);
        
    }
}

发现窗口关闭不掉，停止java程序。

使用封装

package com.gui;

import java.awt.*;


public class TestFrame2 {
    public static void main(String[] args) {
        //展示多个窗口
        MyFrame myFrame1 = new MyFrame(100, 100, 200, 200, Color.blue);
        MyFrame myFrame2 =new MyFrame(300,100,200,200,Color.red);
        MyFrame myFrame3 =new MyFrame(100,300,200,200,Color.yellow);
        MyFrame myFrame4 =new MyFrame(300,300,200,200,Color.green);
    }
}
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));

        //设置窗口大小、窗口弹出的初始位置
        setBounds(x, y, w, h);
        //设置背景颜色
        setBackground(color);
        //设置可见性
        setVisible(true);
    }

}

Panel

通过panel将窗口进行划分，对frame进行布局

package com.gui;

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

//Panel 可以看成一个空间，但是不能单独存在  Panel需要放到frame上
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(69, 206, 63));
        //panel设置坐标，相对于frame
        panel.setBounds(50,50,400,400);
        panel.setBackground(new Color(205, 39, 25));
        //frame.add(panel)
        frame.add(panel);
        //设置可见性
        frame.setVisible(true);
        //监听事件，监听窗口关闭事件 SYstem。exit(0) 解决无法关闭
        //适配器模式：
        frame.addWindowListener(new WindowAdapter() {
            //点击窗口关闭的时候需要做的事情
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });

    }
}

2.3布局管理器

FlowLayout（流式布局）

package com.gui;

import java.awt.*;

public class TestFlowLayout {
    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.LEFT));

        frame.setSize(200,200);
        //添加按钮
        frame.add(button1);
        frame.add(button2);
        frame.add(button3);

        frame.setVisible(true);
    }

}

BorderLayout（默认布局）

package com.gui;

import java.awt.*;

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("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(300,300);
        frame.setVisible(true);
    }
}

GridLayout(表格布局)

package com.gui;
import java.awt.*;
public class TestGridLayout {
    public static void main(String[] args) {
        Frame frame = new Frame("TestGridLayout");
        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();//Java函数  自动选择最优位置
        frame.setVisible(true);
    }
}

2.4布局练习

package com.gui;

import java.awt.*;

public class ExerciseLayout {
    public static void main(String[] args) {
        Frame frame = new Frame();
        frame.setLayout(new GridLayout(2,1));
        //设置窗口大小
        frame.setSize(400,400);
        //需要使用到的画布  在frame的基础上划分两个界面
        Panel top = new Panel(new BorderLayout());
        Panel topMiddle = new Panel(new GridLayout(2,1));
        Panel bottom = new Panel(new BorderLayout());
        Panel bottomMiddle = new Panel(new GridLayout(2,2));
        //向画布中添加元素
        top.add(new Button("T-left"),BorderLayout.EAST);
        top.add(new Button("T-right"),BorderLayout.WEST);
        top.add(topMiddle,BorderLayout.CENTER);
        topMiddle.add(new Button("TMid-top"));
        topMiddle.add(new Button("TMid-bottom"));

        bottom.add(new Button("B-left"),BorderLayout.EAST);
        bottom.add(new Button("B-right"),BorderLayout.WEST);
        bottom.add(bottomMiddle,BorderLayout.CENTER);
        bottomMiddle.add(new Button("bMid-top1"));
        bottomMiddle.add(new Button("bMid-top2"));
        bottomMiddle.add(new Button("bMid-bottom1"));
        bottomMiddle.add(new Button("bMid-bottom2"));
        //添加画布到容器
        frame.add(top);
        frame.add(bottom);
        //设置窗口大小固定
        frame.setResizable(false);
        //设置可见
        frame.setVisible(true);

    }
}

2.5事件监听

package com.gui;

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 TestActionEvent {
    public static void main(String[] args) {
        //按下按钮触发一些事件
        Frame frame = new Frame();
        Button button = new Button("Test");
// 因为.addActionListener();需要一个ActionListener 所以我们需要构造一个ActionListener
        MyActionLinster myActionLinster = new MyActionLinster();
        button.addActionListener(myActionLinster);

        frame.add(button,BorderLayout.CENTER);
        frame.pack();
        windowClose(frame);//关闭窗口
        frame.setVisible(true);
    }
    //关闭窗口事件
    private static void windowClose(Frame frame){
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }
}
class  MyActionLinster implements ActionListener{

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("aaa");
    }
}

多个按钮公用一个监听器

package com.gui;

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 TestActionEvent02 {
    public static void main(String[] args) {
        //按下按钮触发一些事件
        Frame frame = new Frame();
        Button button1 = new Button("start");
        Button button2 = new Button("stop");
        //设置按钮的参数  默认为按钮名称
        button2.setActionCommand("b-stop");
        MyMonitor myMonitor = new MyMonitor();
        button1.addActionListener(myMonitor);
        button2.addActionListener(myMonitor);

        frame.add(button1,BorderLayout.WEST);
        frame.add(button2,BorderLayout.EAST);
        frame.pack();
        windowClose(frame);//关闭窗口
        frame.setVisible(true);
    }
    //关闭窗口事件
    private static void windowClose(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) {
        System.out.println("按钮被触发--"+e.getActionCommand());
        if(e.getActionCommand().equals("start")){
            System.out.println("开始");
        }else{
            System.out.println("结束");
        }
    }
}

2.6输入框TextFiled

package com.gui;

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

public class TestTextField {
    public static void main(String[] args) {
        new MyFrame02();
    }
}
class MyFrame02 extends Frame{
    public MyFrame02(){
        TextField textField = new TextField();
        add(textField);
        MyActionListener02 myActionListener02 = new MyActionListener02();
        //按下enter  触发输入框事件
        textField.addActionListener(myActionListener02);

        //设置替换编码
        textField.setEchoChar('*');
        setVisible(true);
        pack();
    }
}
class MyActionListener02 implements ActionListener{

    @Override
    public void actionPerformed(ActionEvent e) {
        TextField field=(TextField)e.getSource();
        System.out.println(field.getText());
        //设置文本框为空
        field.setText("");
    }
}

简易计算器，组合+内部类（oop原则：组合大于继承！）

未优化代码

package com.gui;

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

public class ExerciseCalculator {
    public static void main(String[] args) {
        new Calculator();
    }
}
//计算器类
class Calculator extends Frame{
    public Calculator(){
        //三个文本框
        TextField num1 = new TextField(10);//字符数
        TextField num2 = new TextField(10);
        TextField num3 = new TextField(20);
        //一个按钮
        Button button = new Button("=");
        //一个标签
        Label label = new Label("+");
        //为按钮绑定事件
        button.addActionListener(new MyCalculatorActionListener(num1,num2,num3));
        //布局
        setLayout(new FlowLayout());
        add(num1);
        add(label);
        add(num2);
        add(button);
        add(num3);
        pack();
        setVisible(true);

    }
}
//监听器类
class MyCalculatorActionListener implements ActionListener{
    private TextField num1;
    private TextField num2;
    private TextField num3;
    //获取变量
    public MyCalculatorActionListener(TextField num1,TextField num2,TextField num3){
        this.num1=num1;
        this.num2=num2;
        this.num3=num3;
    }
    @Override
    public void actionPerformed(ActionEvent e) {
        //获取要计算的数据
        int n1=Integer.parseInt(num1.getText());
        int n2=Integer.parseInt(num2.getText());
        //计算并放入num3中
        num3.setText(""+(n1+n2));
        //清楚前两个框中的数据
        num1.setText("");
        num2.setText("");
    }
}

优化代码

package com.gui;

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

public class ExerciseCalculator {
    public static void main(String[] args) {
        new Calculator().Loading();
    }
}
//计算器类
class Calculator extends Frame{
    //属性
    TextField num1,num2,num3;
    //方法
    public void Loading() {
        //三个文本框
        num1 = new TextField(10);//字符数
        num2 = new TextField(10);
        num3 = new TextField(20);
        Button button = new Button("=");
        Label label = new Label("+");
        //为按钮绑定事件
        button.addActionListener(new MyCalculatorActionListener(this));
        //布局
        setLayout(new FlowLayout());
        add(num1);
        add(label);
        add(num2);
        add(button);
        add(num3);
        pack();
        setVisible(true);
    }
}
//监听器类
class MyCalculatorActionListener implements ActionListener{
    Calculator calculator=null;
    //获取变量
    public MyCalculatorActionListener(Calculator calculator){
       this.calculator=calculator;
    }
    @Override
    public void actionPerformed(ActionEvent e) {
        //获取要计算的数据
        int n1=Integer.parseInt(calculator.num1.getText());
        int n2=Integer.parseInt(calculator.num2.getText());
        //计算并放入num3中
        calculator.num3.setText(""+(n1+n2));
        //清楚前两个框中的数据
        calculator.num1.setText("");
        calculator.num2.setText("");
    }
}

完全改造面对对象

package com.gui;

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

public class ExerciseCalculator {
    public static void main(String[] args) {
        new Calculator().Loading();

    //方法
    public void Loading() {
        //三个文本框
        num1 = new TextField(10);//字符数
        num2 = new TextField(10);
        num3 = new TextField(20);
        Button button = new Button("=");
        Label label = new Label("+");
        //为按钮绑定事件
        button.addActionListener(this);
        //布局
        setLayout(new FlowLayout());
        add(num1);
        add(label);
        add(num2);
        add(button);
        add(num3);
        pack();
        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        //获取要计算的数据
        int n1=Integer.parseInt(num1.getText());
        int n2=Integer.parseInt(num2.getText());
        //计算并放入num3中
        num3.setText(""+(n1+n2));
        //清除前两个框中的数据

            g.setColor(Color.BLUE);
            g.fillOval(point.x,point.y,10,10);
        }
    }
    //继承MouseListener需要实现这个接口中的所有方法 我们只用到其中的按压方法故选择适配器模式
    private  class  MyMouseListener extends MouseAdapter{
        @Override
        public void mousePressed(MouseEvent e) {
            MyMouse myMouse= (MyMouse) e.getSource();//返回当前对象----返回MyMouse(Frame) 用于获取鼠标资源
            //当鼠标点击时获得这个点的位置
            points.add(new Point(e.getX(),e.getY()));
            //鼠标点击后  画笔 重新画图 
            myMouse.repaint();
        }

                    System.out.println("按下了下键，值为："+keyCode);
                    setBackground(Color.BLUE);
                }

            }
        });
    }
}

3、Swing

3.1、窗口、面板

package com.gui.swing;

import javax.swing.*;
import java.awt.*;

public class JFrameDemo {
    //init() 初始化
    public void init(){
        JFrame jf = new JFrame("这是一个JFrame窗口");
        jf.setVisible(true);
        jf.setBounds(100,100,200,200);
        jf.setBackground(Color.green);//无法显示背景颜色
        //设置文字JLabel
        JLabel label = new JLabel("欢迎来到祖安");
        //文本标签居中  设置水平对齐
        label.setHorizontalAlignment(SwingConstants.CENTER);
        jf.add(label);

        //背景颜色无法显示：  容器显示实例化
        Container contentPane = jf.getContentPane();
        contentPane.setBackground(Color.red);
        //关闭事件
        jf.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }
    public static void main(String[] args) {
        //建议一个方法
        new JFrameDemo().init();
    }
}

3.2弹窗

package com.gui.swing;

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

//主窗口
public class DialogDemo extends JFrame {
    public DialogDemo() {
        this.setVisible(true);
        this.setSize(700,500);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        //JFrame放元素，容器
        Container container = this.getContentPane();
        //绝对布局
        container.setLayout(null);
        //按钮
        JButton button = new JButton("点击弹窗");
        button.setBounds(30,30,200,50);

        container.add(button);
        //点击按钮 触发监听事件  弹出一个弹窗
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                new MyDialogDemo();
            }
        });
    }

    public static void main(String[] args) {
        new DialogDemo();
    }
}
//弹窗的窗口
class MyDialogDemo extends JDialog{
    public MyDialogDemo() {
        this.setVisible(true);
        this.setBounds(100,100,500,500);
//        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        Container container = this.getContentPane();
        container.setLayout(null);
        JLabel label = new JLabel("Test");
        label.setBounds(20,20,100,100);
        container.add(label);
    }
}

3.3、标签

label

标签主要用于展示文本和图片

Icon

在Swing中通过Icon接口来创建图标，可以在创建时指定图标的大小、颜色等特性
图标放在标签上，也可以放在按钮上
需要实现类

package com.gui.swing;

import javax.swing.*;
import java.awt.*;
import java.net.URL;

//图标需要实现类,继承JFrame
public class IconDemo extends JFrame implements Icon {

    private int width;
    private  int height;

    public IconDemo()   {
    }

    public IconDemo(int width, int height)  {

        this.width = width;
        this.height=height;
    }
    public  void  init(){
        this.setSize(500,500);

        IconDemo iconDemo = new IconDemo(30, 30);

        //图标放在标签上，也可以放在按钮上
        JLabel label = new JLabel("icontest", iconDemo, SwingConstants.CENTER);
        label.setBounds(10,10,200,220);

        Container container = getContentPane();
        container.add(label);
        this.setVisible(true);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }
    public static void main(String[] args) {
        new IconDemo().init();
    }

    @Override
    public void paintIcon(Component c, Graphics g, int x, int y) {
        g.fillOval(x,y,width,height);
    }

    @Override
    public int getIconWidth() {
        return this.width;
    }

    @Override
    public int getIconHeight() {
        return this.height;
    }
}

ImageIcon

package com.gui.swing;

import javax.swing.*;
import java.awt.*;
import java.net.URL;

public class ImageIconDemo extends JFrame{
    public ImageIconDemo(){
        //获取图片的地址
        JLabel label=new JLabel("ImageIcon");
        //获取IconDemo这个类 同级资源下的 icon01.jpg
        URL url = ImageIconDemo.class.getResource("tx.jpg");
        System.out.println(url);
        ImageIcon imageIcon = new ImageIcon(url);
        label.setIcon(imageIcon);
        label.setHorizontalAlignment(SwingConstants.CENTER);

        Container container = getContentPane();
        container.add(label);

        setVisible(true);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        setBounds(100,100,200,200);
    }
    public static void main(String[] args) {
        new ImageIconDemo();

    }
}

3.4、面板

JPanel

package com.gui.swing;

import javax.swing.*;
import java.awt.*;

public class TestJPanel extends JFrame {

    public TestJPanel()   {
        //所有操作都放在面板上进行操作
        // 1.获得Container（容器）
        Container container = this.getContentPane();
        //2.设置容器的样子
        container.setLayout(new GridLayout(2,1,10,10));//两行一列上下间距为10
        //创建面板
        JPanel jPanel1 = new JPanel(new GridLayout(1,3));
        JPanel jPanel2 = new JPanel(new GridLayout(1,2));
        JPanel jPanel3 = new JPanel(new GridLayout(2,2));
        jPanel1.add(new Button("1"));
        jPanel1.add(new Button("1"));
        jPanel1.add(new Button("1"));
        jPanel2.add(new Button("2"));
        jPanel2.add(new Button("2"));
        jPanel3.add(new Button("3"));
        jPanel3.add(new Button("3"));
        jPanel3.add(new Button("3"));
        jPanel3.add(new Button("3"));

        container.add(jPanel1);
        container.add(jPanel2);
        container.add(jPanel3);
        this.setSize(500,400);
        this.setVisible(true);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

    }

    public static void main(String[] args) {
        new TestJPanel();
    }
}

        JTextArea jTextArea = new JTextArea(20,50);
        //设置默认文本
        jTextArea.setText("春风秋月冬雪风，留着残荷听雨声，冷眼看浮生如梦烟雨化飞龙。");
        //Scroll面板
        JScrollPane scrollPane = new JScrollPane(jTextArea);
        container.add(scrollPane);
        this.setBounds(100,100,300,500);
        this.setVisible(true);

        //将一个图片变为图标
        URL resource = TestJButton01.class.getResource("tx.jpg");
        Icon icon = new ImageIcon(resource);
        //把这个图标放在按钮上
        JButton jButton = new JButton();
        jButton.setIcon(icon);
        //提示文本  当鼠标放上去生效
        jButton.setToolTipText("成果");

        container.add(jButton);
        this.setBounds(100,100,300,500);
