get-fixed-box

Arguments: window-or-screen box &optional scroll-p cursor

Waits for the user to press or unpress a mouse-button, and then returns the coordinates of a box that has been drawn continuously to follow mouse movement during the wait, beginning at box, which must be a box object (see make-box). The width and height of the box remains the same.

window-or-screen should be a window or the screen. The screen is the value returned by (screen *system*). See screen and *system*.

If scroll-p is true, the window (identified by window-or-screen) will be scrolled if the cursor moves outside it. Sets the stream cursor to cursor while running. If the cursor argument is unspecified or t, a stream default is used (typically the cross-hair cursor).

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