There is no way (that I know) to force the slider values.

One alternative, though, might be a "spinner" widget. This
is a compound widget that has a text box, with the value
of the spinner, next to a couple of buttons with images
of up and down arrows on them. When you click the up arrow
the spinner increases by some set increment. (One, in your
case.) If you hold the button down, the increment "spins"
very quickly. It is nearly as fast as a slider for most
applications, and takes up far less space.

This would give you practice building your own
compound widgets. Something every widget programmer ought
to know how to do anyway! :-)

I have one coded up for my Catalyst Library, so I could
help with the "spin it" part of the event handler, if you
get stuck with that.

Cheers,

David
