exterior

Arguments: window-or-screen

Returns the exterior box of window-or-screen. The box is relative to the upper-left corner of the "page" of the parent window, or of the screen if there is no parent window. (A "page" is the logical canvas of a window, on which drawing is done and which is sometimes scrollable. So if the parent window is not scrolled, then the box is relative to the upper-left corner of the parent's interior.) The unit of measurement is pixels.

The screen is the value returned by (screen *system*). See screen and *system*. This function be used with setf to modify the exterior (see track-limits).

To find the exterior without consing a box object, call nexterior instead. To find the exterior that the window would have when its state is :normal, call normal-exterior.
