Re: Resizing object graphics on X

[Pavel Romashkin <promashkin(at)cmdl.noaa.gov>]

If you take a look at a caveat for DIMENSIONS keyword for the
IDGgrWindow object, then you will notice that it says "Note - Changing
DIMENSIONS properties is merely a request and may be ignored for various
reasons. "
Therefore, I think that your Windows toolkit fullfills that request *for
some reason*, while X ignores it for *some other reason*. Try the
following, it works on either one. Besides, at first I could see nothing
but a black box on both Mac and X, because the machines I have do not
(apparently) support a default OS backing store. So I added that, too.
Cheers,
Pavel
