Question

java鼠标坐标是像素值

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);
}
}

Answer 2

是像素值
当分辨率变化时，其实如果能够得到相对屏幕的鼠标坐标，相对窗口的也就出来了。
我试了一下百分比的情况，不行。
代码如下：

HDC hdc=GetDC(NULL); //获得屏幕设备描述表句柄

int i=GetDeviceCaps(hdc,HORZRES); //查询屏幕水平分辨率，并返回在变量i中

int j=GetDeviceCaps(hdc,VERTRES); //查询屏幕垂直分辨率，并返回在变量j中

ReleaseDC(NULL,hdc); //释放屏幕设备描述表

sprintf(str,"水平分辨率:%d,垂直分辨率:%d\n",i,j);

//MessageBox(NULL,str,"屏幕分辨率",0);

Sleep(3000);

POINT lpPoint = {0};

::GetCursorPos(&lpPoint);

ScreenToClient(hwind, &lpPoint);

lpPoint.x = 553 * (float)i/1152;

lpPoint.y = 166 * (float)j/864;

SendMessage(hwind,WM_LBUTTONDOWN,MK_LBUTTON,MAKELONG(lpPoint.x, lpPoint.y));

SendMessage(hwind,WM_LBUTTONUP,MK_LBUTTON,MAKELONG(lpPoint.x, lpPoint.y));

sprintf(str,"水平坐标:%d,垂直坐标:%d\n",lpPoint.x,lpPoint.y);

MessageBox(NULL,str,"鼠标位置",0);

是的 是像素值
