Hi Scott,
as of version 4.6 and later this does seem to give the same of the max
scroll whether your force it by setting the scroll to a very large number or
use this script:
-------------------------------------------
on mouseUp
put the formattedHeight of field 1 into tFormat
put the height of field 1 into tHeight
put the borderwidth of field 1 into tBorder
put 0 into tBorderKorr
if tBorder > 0 then
put 5 into tBorderKorr
if tBorder <> 2 then
add 1 to tBorderKorr
end if
if not the showBorder of field 1 then
if the hScrollbar of field 1 then
add 2 to tBorderKorr
else
add 4 to tBorderKorr
end if
end if
else -- borderwidth = 0
put 5 into tBorderKorr
end if
if the hScrollbar of field 1 then
add 1 to tBorderKorr
end if
put tFormat - tHeight - tBorderKorr into tSum
set the scroll of field 1 to tSum
--- end of calculation of the max scroll
------------------------------------
set the scroll of field 1 to 100000
-- let it update, not necessary but who knows
unlock screen
wait 5 milliseconds with messages
put the scroll of field 1 into tScroll
put "calculated max scroll " & tSum & cr & "actual max scroll " & tScroll
& cr & "difference " & tSum - tScroll into field 2
-- if the difference is <> 0 then you found a flaw in this
end mouseUp
-----------------------
I don't know the reason why this is the way it is.
This works for me for many different combinations of
borderwidths/visibility/scrollbars. I might have forgotten some combination
though.
If you scroll manually to the max there at times is a 1 pixel difference and
at other times not.
Prior to 4.6 you had to account for the height of the hScrollBar if it was
shown.
Prior to 4.5 on a Mac only you also had to take into account the
focusedBorder if set to true and active.
Kind regards
Bernd
