Hi Nicolas,
The relatively new addition to revTalk, 'wrap', might help here. This example
isn't exactly what you're describing, but I think the same principle could be
applied. I just tested this script in a "LittleArrows" style scrollbar, and it
successfully does an endless loop through the numbers 1 through 12, both
backward and forward, when you click the increment or decrement arrows.
Now imagine lines of text stored in a variable that would be shown in the
field, instead of the numbers.
local sCount
on scrollbarLineInc
put 1,2,3,4,5,6,7,8,9,10,11,12 into tnums
add 1 to sCount
put sCount wrap 12 into fld "counter"
end scrollbarLineInc
on scrollbarLineDec
put 12,11,10,9,8,7,6,5,4,3,2,1 into tnums
subtract 1 from sCount
if sCount is 0 then put 12 into sCount
put sCount wrap 12 into fld "counter"
end scrollbarLineDec
