JAVA实验：图形用户界面编程 原创

JAVA实验：图形用户界面编程

实验目的（分掌握、熟悉、了解三个层次）：

1、 了解GUI开发的相关原理和技巧

2、 掌握AWT事件处理、布局管理器

3、 熟悉Swing组件的使用

第一题

package com.test;
import java.awt.*;
import java.awt.event.*;
 
import javax.swing.*;

public class Demo1 extends JFrame {
	
    /**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	public Demo1() {
    	this.setTitle("教材P334第五题:1");
    	
        final JLabel label = new JLabel("此处显示鼠标右键点击的坐标");
        label.setOpaque(true);
        this.add(label, BorderLayout.NORTH);
        this.setSize(500, 300);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.addMouseListener(new MouseAdapter() {
                public void mouseClicked(MouseEvent e) {
                    if (e.getButton() == e.BUTTON3) {
                        int x = e.getX();
                        int y = e.getY();
                        String banner = "鼠标当前点击位置的坐标是" + x + "," + y;
                        label.setText(banner);
                    }
                }
            });
        this.setVisible(true);
    }
 
    public static void main(String[] args) {
        new Demo1();
    }
}
