Emacs Lisp
For Emacs' own frames (which is what Emacs calls its window system windows), the frame the mouse is over and where the mouse is within that frame can be obtained with
(mouse-pixel-position) => (FRAME . (X . Y))
Or mouse-position for characters instead of pixels.
Works when the mouse is over any Emacs frame, not just when that frame is the active focused window.
There's no particularly easy way to inquire about a non-Emacs focused window, only generic X11 or similar approaches run externally.
ERRE
This example program, taken from distribution disk, shows the mouse position in a text field at the bottom-right corner and updates when the mouse is moved.

Java
{{works with|Java|1.5+}} The mouse position can be checked at any time by calling
Point mouseLocation = MouseInfo.getPointerInfo().getLocation();
This returns a point on the entire screen, rather than relative to a particular window. This call can be combined with getLocation() from any Component (including a Frame, which is a window) to get the location relative to that Component.
JavaScript
In a browser environment, it's impossible to actually get the cursor position at the specific moment. You must wait for user input (movement, click, etc). One of many ways to add an event listener:
document.addEventListener('mousemove', function(e){ var position = { x: e.clientX, y: e.clientY } }
In the above example, the window may not be external. It must in fact be a web browser window, which runs the script.

The following example shows three labels being updated with the mouse position.
The globalmotion label is updated whenever the mouse moves anywhere within the window, but not outside it.
The canvasmotion label is updated whenever the mouse moves within the canvas, but not elsewhere in the window (or beyond).
The timer label is updated every three seconds and gets mouse positions anywhere on the whole screen, whether it moves or not.
Note that canvasmotion coordinates are relative to the top left of the canvas, whereas the other two are absolute. {{libheader|pGUI}}

The mouse position can be obtained by these two commands:
x = WindowMouseX(#MyWindow)
y = WindowMouseY(#MyWindow)
This example repeatedly shows the mouse coordinates relative to the window created in the application.

Mouse position using Tkinter graphics library nearly universally included in installations of Python. There are other alternatives but they are platform specific.
Shows position of mouse while it is over the program windows and changes color of window when mouse is near (<10) hot spot 100,100.

The mouse position can be queried at any time with a function in a GUI context.

Rust
Prints current location of the mouse cursor relative to any active window. This example relies on the Windows API.

The functions [http://seed7.sourceforge.net/libraries/graph.htm#pointerXPos%28in_PRIMITIVE_WINDOW%29 pointerXPos] and [http://seed7.sourceforge.net/libraries/graph.htm#pointerYPos%28in_PRIMITIVE_WINDOW%29 pointerYPos] from the [http://seed7.sourceforge.net/libraries/graph.htm graph.s7i] library determine the actual X and Y position of the mouse pointer, relative to the given window:
xPos := pointerXPos(curr_win);
yPos := pointerYPos(curr_win);
Smalltalk
Sending the message position to the activeHand of the World returns a Point object:

{{libheader|Tk}}
package require Tk 8.5 set curWindow [lindex [wm stackorder .] end] # Everything below will work with anything from Tk 8.0 onwards set x [expr {[winfo pointerx .] - [winfo rootx $curWindow]}] set y [expr {[winfo pointery .] - [winfo rooty $curWindow]}] tk_messageBox -message "the mouse is at ($x,$y) in window $curWindow"
Visual Basic
There are two methods for determining where the mouse pointer is. The first only works when the pointer is actually over the window containing the code. This actually works for any control that has a MouseMove event, but it doesn't work if the pointer is over ''anything else'', including controls on the form (so if the pointer is over a button on the current form, the event will only fire for the button, ''not'' the form).
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
'X and Y are in "twips" -- 15 twips per pixel
Me.Print "X:" & X
Me.Print "Y:" & Y
End Sub
The second method uses the [[wp:Windows API|Windows API]],
and can be easily translated to any language that can make API calls.
This example uses a Timer control to check the mouse position.
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Type POINTAPI
'X and Y are in pixels, with (0,0) being the top left corner of the primary display
X As Long
Y As Long
End Type
Private Pt As POINTAPI
Private Sub Timer1_Timer()
GetCursorPos Pt
Me.Cls
Me.Print "X:" & Pt.X
Me.Print "Y:" & Pt.Y
End Sub
XPL0
GetMousePosition(0) = X coordinate; 1 = Y coordinate. For video modes $0..$E and $13 the maximum coordinates are 639x199, minus the size of the pointer. For modes $F..$12 the coordinates are the same as the pixels. VESA graphic modes are (usually) 639x479 regardless of the resolution. For 80-column text modes divide the mouse coordinates by 8 to get the character cursor position.
The mouse cursor location is always relative to the upper-left corner of the screen. A window may be externally created ... using a fair amount of code because the version of XPL0 used with these Rosetta Code examples does not make Windows applications (however see "Simple windowed application").
