我基本上需要找出鼠标指针的位置。我试过这个:

package main;

import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;

public class MouseListen implements MouseMotionListener{

    public void mouseDragged(MouseEvent arg0) {     
    }

    public void mouseMoved(MouseEvent arg0) {
        mouseX = arg0.getX();
        mouseY = arg0.getY();
    }

   public int mouseX, mouseY;

} 

现在只有在 JFrame 内才有效 window 。我怎样才能在 JFrame 之外找到鼠标的 x 和 y 位置？

MouseInfo.getPointerInfo().getLocation().x;
MouseInfo.getPointerInfo().getLocation().y;
