While I'm waiting anxiously for Philip's new program, like
the rest of you, I should point out that XINTERANIMATE doesn't
take control of anything. There is nothing going on that would
prevent the user from going back to the original program
and launching *another* version of XINTERANIMATE, or doing
some more work while the animation plays along happily in
the corner of the display. (Whoops, except that XINTERANIMATE
is written with COMMON blocks and can only allow one copy
of itself to exist at any one time. A pity, really. Someone
should have read my book. :-)
So I am confused about the notion of getting XINTERANIMATE
to return control to the main program. Where else *is* the
control, except in the main program. After all, this is
the program that spawned XINTERANIMATE, correct? When the
user quits XINTERANIMATE the other widget program (programs ?)
should be there for them to interact with. There are certainly
no limitations on how many widget programs can be running
simultaneously that I know about.
Cheers,
David
