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
<
;; => (FRAME . (X . Y))</syntaxhighlight>
Or <code>mouse-position</code> 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.

The mouse position can be checked at any time by calling
<
This returns a point on the entire screen, rather than relative to a particular window. This call can be combined with <code>getLocation()</code> from any <code>Component</code> (including a <code>Frame</code>, which is a window) to get the location relative to that <code>Component</code>.
=={{header|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:
<
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 globalmotion label is updated whenever the mouse moves anywhere within the window, but not outside it.<br>
The canvasmotion label is updated whenever the mouse moves within the canvas, but not elsewhere in the window (or beyond).<br>
The timer label is updated every three seconds and gets mouse positions anywhere on the whole screen, whether it moves or not.<br>
Note that canvasmotion coordinates are relative to the top left of the canvas, whereas the other two are absolute.

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).
<syntaxhighlight lang="vb">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

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 <code>Timer</code> control to check the mouse position.

For video modes $0..$E and $13 the maximum coordinates are 639x199,

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.
