I updated the article with a picture of the problem with the QUIT
button, so those of you who work with something other than Windows
can see what your beautiful IDL code looks like running on your boss's
machine.

No, I think the problem must be something else. This code
behaves about like I think you must be expecting it to. That
is, nothing much happens and all sizes are reported as the
same.

After all the rigamarole and complexity of separating widgets
from the iTool visualization layer, maybe this is what they
intend to do with the big Eclipse update. Ditch widgets and
give us iTools with modern cross-platform GUIs. That would
certainly get rid of those irritating customers who use direct
graphics and complain all the time! :-)
Cheers,
David
