How to Display Mouse Coordinates

Displaying mouse coordinates usually means showing the x and y positions of the mouse cursor on the screen in real-time. The method for doing this can vary depending on the operating system and the context in which you need the coordinates. Here’s how you can display mouse coordinates in various environments:

Windows

Using Developer Tools in Browsers

In web browsers like Chrome, Firefox, or Edge, you can open Developer Tools (by pressing F12 or right-clicking and selecting “Inspect”) and hover over elements on the web page to see their coordinates. However, for the mouse position anywhere on the screen:

  1. You might need a small script or program.
  2. PowerShell script can be used to track the mouse position.
  3. Third-party applications are available that can display the coordinates on screen.

Using Third-Party Software

There are various small utilities available that can display the mouse coordinates on the screen or save them to a file. For example, “MousePos” (Mouse Position) software can show the coordinates in real-time.

macOS

On a Mac, you can see the mouse coordinates using several methods:

Using the Quartz Debug Tool (Developer Tools)

  1. Open the Quartz Debug tool (part of the Graphics Tools for Xcode which can be downloaded from the Apple Developer website).
  2. Within Quartz Debug, go to Window > UI Element Inspector.
  3. This will display the mouse coordinates as you move the cursor around the screen.

Using AppleScript

You can write a simple AppleScript or use the Script Editor to display the mouse position:

repeat
set mousePos to do shell script "/usr/bin/env python -c 'from Quartz.CoreGraphics import CGEventGetLocation, CGEventCreate; print CGEventGetLocation(CGEventCreate(None))'"
display dialog "Mouse position: " & mousePos buttons {"OK"} default button 1
end repeat

Using Terminal Commands

The terminal can be used to run commands that track the mouse position:

while true; do
# This will print the mouse coordinates.
clear
x=$(defaults read com.apple.driver.AppleBluetoothMultitouch.mouse MouseHorizontalScroll -int 1)
y=$(defaults read com.apple.driver.AppleBluetoothMultitouch.mouse MouseVerticalScroll -int 1)
echo "X: $x Y: $y"
sleep 1
done

Linux

On Linux, you can use the xev command to display mouse events, including the coordinates when the mouse is moved within a specified window:

  1. Open a terminal.
  2. Type xev and press Enter.
  3. Move the mouse into the square window that appears to track the coordinates.

Alternatively, you can use the xdotool command in a script to get the current mouse location:

while true; do
xdotool getmouselocation
sleep 1
done

In Programming Environments

If you’re working within a programming environment, most languages provide a way to get the mouse position.

In JavaScript for Web Pages

For a web page, you can display mouse coordinates with JavaScript:

document.addEventListener('mousemove', function(e) {
console.log("X: " + e.clientX + " Y: " + e.clientY);
});

In Python with Pygame

If you’re using Pygame for development:

import pygame

# Your Pygame loop
for event in pygame.event.get():
if event.type == pygame.MOUSEMOTION:
print("Mouse position:", pygame.mouse.get_pos())

Each method depends on the context you’re working in, whether it’s just for your use while browsing, for development purposes, or within a specific application.
