nget-fixed-box

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

A destructive version of get-fixed-box. The old-box argument is modified to be the box chosen by the user and returned. Like get-fixed-box, this function waits for the user to press or unpress a mouse button after moving the mouse about. Rubber band boxes are drawn continuously to follow mouse movement during the wait, beginning at old-box. The user is only choosing the box location. The width and height of the box remains the same. old-box is then modified to be the box at the button event. old-box is then returned. old-box must be a box (see make-box).

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 t, a stream default is used (typically the cross-hair cursor).
