Well, not given the way CW_FSLIDER is written. But a couple
of well-placed _EXTRA keywords would probably make a five minute
job of it.
But I would ditch the "graphical creation tool", too,
while I was at it. You won't learn anything but bad
habits if you write your code with that. :-)
(It's true that you can write awful widget programs by
hand, too. But at least if you do, you have a better
chance of fixing them.)

Guys who have only been here a few days always
seem to point out that the Emperor has no clothes.
We all know that, but most of us ignore it and go
to work anyway, just because we love him so. :-)
Cheers,
