Can one refer to the location of just the thumb of a scrollbar
relative to its window? I want to chase the thumb with a a graphic...
essentially a transparent rectangle whose left would stick to the left
of a horizontal scrollbar and whose right would follow the thumb as it
moves. I can use the mouseLoc to come close, but it isn't exact, and
I also need to refer to the loc of the thumb from outside the
scrollbarDrag handler.
This is the idea:
on scrollbarDrag newPosition
put the top of graphic "yellowRect" into vTheTop -- maintains
height of graphic
put the bottom of graphic "yellowRect" into vTheBottom --
maintains hieght of graphic
put the left of scrollbar 1 into vTheLeft -- sets left of graphic
to the left of the scrollbar
***put item 1 of (the loc of the THUMB of scrollbar 1) into
vTheRight -- this is the idea... but how??? I can use the mouseLoc
here but it's not precise
set the rect of graphic "yellowRect" to
vTheLeft,vTheTop,vTheRight,vTheBottom
end scrollbarDrag
Thanks
Mark
