My latest oddity is that my littlearrows never reaches its endValue. If I have a control with a startValue of 1 and an endValue of 10, the thumbPosition always stops at 9. I was wondering if this was due to the thumbSize being 1? But then shouldn't my thumbPositional also stop at 2?
It is a little-known oddity of Rev scrollbars that the real page increment is the pageIncrement property value minus the lineIncrement property value and the real end value is the endValue property minus the thumbsize property. Another thing to keep in mind is that the numberFormat property of a slider (sets the number of decimal points shown when show value is set to true) affects the lineIncrement property value (!) and hence also the page increment (!!).
I have Bugzillarated these issues without any relief: the lineIncrement affect on pageIncrement is considered to be a useful FEATURE and so my bug has been resolved as not a bug.
I think there is a design flaw here that has cascaded through the various forms of the scrollbar object.
You can learn to deal with the oddities by playing with a scrollbar with a script like this:
on mouseUp
put the lineInc of me && the pageInc of me && the thumbsize of me
put return & the thumbposition of me && the endvalue of me after msg
end mouseUp
Hope that makes the mud less opaque.
