I can't help you with the iTool part, but this is *exactly*
the program we wrote in the IDL course I taught last week. We used
direct graphic image objects, but we just stuffed one of these
in the UValue of each draw widget. When we clicked on the draw
widget, we made a clone of that image object and placed that
in the large display image object in the main display draw widget.
But I don't have the foggiest idea of how to register a mouse click.
Sorry.

No, no. You completely misunderstand. We love iTools. We just
can't figure out how they work. And some of us, apparently,
are too damn old to learn. :-)

Cheers,

David
