E.2 Functions for Operating on Windows Directly

You can use open-window-stream to give you a CLIM window without incorporating it into a frame. After calling open-window-stream , call window-expose to make the resulting window stream visible.

The following operators are available for manipulating the CLIM primitive layer for window streams.

open-window-stream[Function]	

Arguments: &key port left top right bottom width height borders console default-text-margin default-text-style depth display-device-type draw-p end-of-line-action end-of-page-action initial-cursor-visibility input-buffer label name output-record record-p save-under scroll-bars stream-background stream-foreground text-cursor text-margin viewport vsp window-class
