| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: drawable
Returns the stream that an application should currently draw on for a
drawable
. If
the use-bitmap-stream
property of drawable is true, drawable-stream will return the bitmap-stream
of
drawable. Otherwise, drawable-stream will return the visible window of
the drawable control.
Note that if drawable is not currently on a dialog and use-bitmap-stream
is false, then nil
is returned. This may
cause problems since the appropriate stream is passed automatically to
the drawing functions.
