get-position

Function

Package: common-graphics

Arguments: stream &optional scroll-p cursor

Waits until the user presses a mouse button down, and then returns the current position of the mouse cursor in the stream coordinates of stream. If scroll-p is true, the window (identified by stream) will be scrolled if the cursor moves outside it. Sets the stream cursor to cursor while running. If the cursor argument is t, a default is used (typically the cross-hair cursor).

You may wish to call wait-for-mouse-buttons-up prior to calling get-position to ensure that mouse button releases associated with other actions do not interfere with getting the desired position.
