java 移动鼠标显示即时的坐标位置

我想实现移动鼠标，显示现在鼠标的位置，也就是鼠标移动对应的文本框里的坐标也随着移动，可是现在好像只是鼠标进入时的位置，希望大家帮我改下实现这个功能，谢谢，代码如下：/** * @(#)MouseMove2.java * * * @author  * @version 1.00 2010/6/20 *//** * @(#)MouseMove1.java * * * @author  * @version 1.00 2010/6/20 */import java.awt.*;import java.awt.event.*;import javax.swing.*;public class MouseMove2 extends JFrame implements MouseListener{  int x=0,y=0;     Container cp;     JTextField T;     JButton B1,B2;     public MouseMove2() {     super("Mouse Move");     T=new JTextField(15);     B1=new JButton("OK");     B2=new JButton("Cancel");     cp=getContentPane();     cp.setLayout(new FlowLayout());     cp.add(T);     cp.add(B1);     cp.add(B2);     this.addMouseListener(this);     setSize(400,200);     setVisible(true);     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     }     public void mouseMoved(MouseEvent e){      //x=e.getX();      //y=e.getY();      T.setText("X="+e.getX()+",Y="+e.getY());           }     public void mouseClicked(MouseEvent e){}     public void mouseEntered(MouseEvent e){      T.setText("X="+e.getX()+",Y="+e.getY());     }     public void mouseExited(MouseEvent e){}     public void mousePressed(MouseEvent e){}     public void mouseReleased(MouseEvent e){} public static void main(String[] args){     MouseMove2 frame =new MouseMove2();    }}

package ym;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MouseMove2 extends JFrame {
int x=0,y=0;
Container cp;
JTextField T;
JButton B1,B2;

public MouseMove2() {
super("Mouse Move");
T=new JTextField(15);
B1=new JButton("OK");
B2=new JButton("Cancel");
cp=getContentPane();
cp.setLayout(new FlowLayout());
cp.add(T);
cp.add(B1);
cp.add(B2);
this.addMouseMotionListener(new MyListener());
setSize(400,200);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

class MyListener implements MouseMotionListener {
@Override
public void mouseDragged(MouseEvent e) {}
@Override
public void mouseMoved(MouseEvent e) {
T.setText("X="+e.getX()+",Y="+e.getY());
}
}

public static void main(String[] args){
MouseMove2 frame =new MouseMove2();
}
}
