Well, let us know when you try it. :-)
I've no particular beef with iTools if they do
what you want them to do. (Of course, I think
aesthetically they are a disaster. For example,
why would an iSurface plot come up with a default
action to *translate* it, for God's sake?) Other
than the fact I just don't find them at all intuitive,
which I have always blamed on myself and not on iTools,
I just don't find them handy for anything I do.
I know for a fact that if you try to program them
to work in your own personal style you better be
prepared for a long siege. They are, in a word,
freaking complicated. You seem to be figuring
them out, and that at least gives me hope.
Putting them into the hands of beginning IDL users,
whom I believe is their intended audience, just makes
me very, very nervous. They have a tendency to ask these
really simple questions that I just have an extremely
difficult time answering.
If you want a shortcut for building object graphics
programs, I recommend Revolution, which I think you
can find on the IDL Code Contrib web page. That program
produces beautiful code which you can actually use and
modify easily for your own purposes. And, a significant
bonus, you might actually learn about IDL object programming
in the process. Something I doubt seriously would happen
with a similar time investment in the iTools code.
Cheers,
David
