Why Output Keywords Fail in cgWindow [message #85416]

Folks,

I had a question this morning that had to do with why output keywords
fail to produce the correct output when the command they are used with
is added to cgWindow. I've answered this question before, but I was
surprised to find I had never written an article about it. I have now.

The answer has to do with the way IDL commands are "played back" when
the graphics window is resized. I use CALL_PROCEDURE to replay the
commands that have been loaded into cgWindow. Unfortunately,
CALL_PROCEDURE does not have a mechanism for returning output keywords.

You can find a description of the problem and a simple workaround in
this article:

Cheers,

David
