怎么我用Java窗外获取鼠标点击的坐标

Answer 1

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.EventListener;
class myMouseListener implements MouseMotionListener
{
public void mouseMoved(MouseEvent e){
int x=e.getX();
int y=e.getY();
String s="当前鼠标坐标:"+x+','+y;
MouseMove.lab.setText(s);
}
public void mouseDragged(MouseEvent e){};
}
public class MouseMove extends JFrame{
public static JLabel lab=new JLabel();
public MouseMove() {
}
public static void main(String [] args)
{
// MouseMove fm=new MouseMove("鼠标坐标测试");
JFrame fm=new JFrame("鼠标坐标测试");
JPanel fp=new JPanel();
fp.addMouseMotionListener(new myMouseListener());//对在面板上的鼠标移动进行监听。
Container con=fm.getContentPane();
fp.add(lab);
con.add(fp);
fm.setSize(500,400);
fm.setVisible(true);
fm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
