Now, I'm not so sure. I've written a bit of code, (well quite a large bit of
code) which replaces XINTERANIMATE, and my code is a great deal easier to
understand and so you could manipulate it to do what ever you wanted and
link it in with your current widget program, or if it's not a widget program
then call form the program.
There are several advantages to my program, if you wanted to put a colour
bar on the animation, or anything else, then it is very easy to do. You can
check out a post I put about it titled : a replacement for xinteranimate.
But the main advantage is to do with pixmap storage space, my program only
stores the minimum amount, i.e. it stores no black space, and never stores
more than one copy of anything, so it would only store one colour bar in
pixmaps.
Basically, I guess the fact that you would be able to change the code to
exactly what you wanted, quite easily, rather than xinter.. which is written
in such dense code that it is hard to understand, means that my program
would be ideal.

As for the problem you highlight here, all you would have to do is change
the event handler on my program for the quit button, so that it notified,
some other program - it would be a piece of cake to do. You could change the
code quite easily.
The program is currently, about to get publication permission - I have to
get this before I can let others even look at it, and when that's done I'll
e-mail a copy to you, with some examples of how to use it, and then I would
be delighted to help you change the code to suit your particular needs.
cheers,
