GUI编程
1、 简介
【相关组件】:
- 窗口
- 弹窗
- 面板
4.文本框
5.列表框
6.按钮
7.图片
8.监听事件
9.鼠标
10.键盘事件
11.破解工具
-
GUI核心开发技术:Swing和AWT,
-
不流行原因:1. 界面不美观;2. 需要jre环境!
-
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,了解架构!
2、 AWT
2.1、Awt介绍
-
包含了很多类和接口;
-
GUI:图形用户界面编程;
-
元素: 窗口,按钮,文本框java.awt包里
2.2、组件和容器
1、Frame
package GUI;
import java.awt.*;
//GUI的第一个界面
public class TestFrame1 {
public static void main(String[] args) {
//Frame,JDK, 看源码!
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(Color.blue); //第一种设置背景颜色,使用默认的背景颜色
frame.setBackground(new Color(45, 52, 57));
//弹出初始位置
frame.setLocation(200,200);
//设置大小固定
frame.setResizable(false);
}
}
结果显示:
- 创建多个界面
package GUI;
import java.awt.*;
//生成多个GUI界面
public class TestFrame2{
public static void main(String[] args) {
MyFrame myFrame1 = new MyFrame(100,100,200,200,Color.blue);
MyFrame myFrame2 = new MyFrame(300,100,200,200,Color.green);
MyFrame myFrame3 = new MyFrame(100,300,200,200,Color.yellow);
MyFrame myFrame4 = new MyFrame(300,300,200,200,Color.red);
}
}
class MyFrame extends Frame{
static int id = 0; //可能存在多个窗口,我们需要一个计算器
public MyFrame(int x,int y,int w,int h,Color color){
super("MyFrame+"+(++id));
setBackground(color);
setBounds(x,y,w,h);
setVisible(true);
}
}
结果显示:
2、面板Panel
【关闭】:此例子提供关闭的问题
package GUI;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class TestPanel1 {
public static void main(String[] args) {
Frame frame = new Frame();
Panel panel = new Panel();
//设置布局
frame.setLayout(null);
//坐标
frame.setBounds(300,300,500,500);
//设置背景颜色
frame.setBackground(new Color(40,161,35));
//panel(面板) 设置坐标,相对于frame
panel.setBounds(50,50,400,400);
panel.setBackground(new Color(194,15,60));
//frame.add(panel)
frame.add(panel);
frame.setVisible(true);
//监听事件,监听窗口关闭事件 System.exit(0)
//适配器模式:
frame.addWindowListener(new WindowAdapter() {
//窗口点击关闭的时候,需要做的事情
@Override
public void windowClosing(WindowEvent e) {
//结束程序
System.exit(0);
}
});
}
}
输出结果显示:
3、布局管理器

public class TestFrameLayout1 {
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()); //默认为居中
// frame.setLayout(new FlowLayout(FlowLayout.LEFT)); //设置为左边
frame.setLayout(new FlowLayout((FlowLayout.RIGHT))); //设置为右边
frame.setSize(400,400);
frame.add(button1);
frame.add(button2);
frame.add(button3);
frame.setVisible(true);
//停止启动
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}

总结:
- Frame是一个顶级窗口;
- Panel无法单独显示,必须添加到某个容器;
- 布局管理器
- 流式
- 东西南北中
- 表格
- 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?
实现事件监听
package 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 TestActionEvent1 {
public static void main(String[] args) {
//按下按钮,触发一些事件
Frame frame = new Frame();
Button button = new Button("button1");
//因为,addactionlistener()需要一个ActionListener,所以我们需要构造一个ActionListener
MyActingLinstener myActingLinstener = new MyActingLinstener();
button.addActionListener(myActingLinstener);
frame.add(button);
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);
}
});
}
}
//事件监听
class MyActingLinstener implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("aaa"); //创建监听事件
}
}
输出结果显示:
两个按钮同时实现一个监听
package 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 TestActionTwo {
public static void main(String[] args) {
Frame frame = new Frame("启动-停止"); //创建一个顶级窗口
frame.setLayout(new GridLayout(2,1)); //将顶级窗口弄成表格布局
frame.setSize(400,400); //设置窗口大小
frame.setLocation(200,200); //设置窗口出现位置
frame.setVisible(true); //设置顶级窗口可见
//创建两个面板
Panel p1 = new Panel(new BorderLayout());
Panel p2 = new Panel(new BorderLayout());
//创建两个按钮
Button button1 = new Button("start");
Button button2 = new Button("stop");
button2.setActionCommand("button2-stop"); //设置需要接收的字符串
MyMonitor myMonitor = new MyMonitor(); //new一个事件
//将两个按钮都指向一个事件
button1.addActionListener(myMonitor);
button2.addActionListener(myMonitor);
//将两个按钮分别加入到p1,p2面板中,并以表格布局方式布局
p1.add(button1 ,BorderLayout.CENTER);
p2.add(button2,BorderLayout.CENTER);
//将两个面板加入到顶级窗口中
frame.add(p1);
frame.add(p2);
WindosExit(frame); //调用关闭窗口事件
}
//创建一个窗口关闭事件
private static void WindosExit(Frame frame){
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
//创建一个事件
class MyMonitor implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("按钮被点击了:msg=>"+e.getActionCommand());
}
}
输出结果显示:
2.5、输入框TextField 监听
package GUI;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class TsetText1 {
public static void main(String[] args) {
//启动!
new MyFrame1();
}
}
class MyFrame1 extends Frame{
public MyFrame1(){
TextField textField = new TextField(); //创建文本框
add(textField); //将文本框加入到顶级窗口里
MyActionListener2 myActionListener2 = new MyActionListener2(); //监听这个文本框输入的文字
textField.addActionListener(myActionListener2);//按下enter 就会出发这个输入框的事件
textField.setEchoChar('*');//设置替换编码
setVisible(true); //显示窗口文件
pack(); //顶级窗口适应大小
//创建关闭窗口事件
addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
class MyActionListener2 implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
//(TextField)e.getSource():强转
TextField field = (TextField)e.getSource();// 获得一些资源,返回的一个对象
System.out.println(field.getText()); //获得输入框的文本
field.setText(""); //PS:null:表示对象; "":表示为空
}
}
输出结果显示:
