No, no, no. In fact, these days, ALL
of my compound widgets
 are written as objects. The purpose
of the FUNC_GET_VALUE
 for these objects is to return the
"self" object, which
 I can then control by means of methods.
This makes it
 incredibly easy to manipulate the
internal widgets of
 a compound widget.

I've been meaning to write an example
of this, but most
 of my real programs are too complex
for instructional
 programs, and I haven't had the time
to write a simple,
 but meaningful, example. I promise
to do it, but I really
 can't say when. :-)

Cheers,

 Hi,
    1) The students are back
so our network is *really* screwed(up)
       so
double posts may result so apologies in advance.
    2) After watching 
"South Park" last night I realized that I
       should
have made the widget do both float and integer, I
       guess
since SP is in Colorado and David lives in Colorado
       I made
the connection ... :)
    3) The extremely thin
IDL volume on Objects & Graphics led me
       to
believe that I would be spending far too much time learning
       Object
Oriented Programming without a net and not getting any
       work
done.  David's statement about "programs are too complex"
       seems
to justify my delay into OOP.
 Doug
