drawable-stream

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.
