复制代码 代码如下:

package Game;

import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;   
/**
 * 鼠标监听器的类
 * 
 * @author Administrator
 * 
 */ 
public class Listener extends MouseAdapter { 
    private Graphics g; 
    private int x = 5, y = 620; 
    private int width = 100, height = 10; 
 
    public Listener(Graphics g) { 
        this.g = g; 
    } 
 
    public void mouseMoved(MouseEvent e) { 
        // 设置画布对象颜色 
        synchronized (this.g) { 
            g.setColor(Color.black); 
            g.fillRect(x, y, width, height); 
            x = e.getX(); 
            g.setColor(java.awt.Color.green); 
            g.fillRect(x, y, width, height); 
        } 
    } 
 
    /**
     * 得到x的方法
     * 
     * @return:x
     */ 
    public int getX() { 
        return x; 
    } 
 

运行效果如下图所示:
