Hello,
I thought this would be easy. It isn't working right. Don't know what to do.
The script:
on mouseUp
put "537,1" into locVar
repeat with i = 1 to 650
set the loc of field "foo" to locvar
add 1 to item 2 of locVar
wait 1 millisecs
end repeat
end mouseUp
It works, but it takes a whole lot longer than 650 milliseconds for the loc of
the field to scroll to the bottom -- more like ten seconds, and it does not
scroll smoothly.
I tried this instead:
on mouseUp
put "537,1" into locVar
repeat with i = 1 to 216
set the loc of field "foo" to locvar
add 3 to item 2 of locVar
wait 3 millisecs
end repeat
end mouseUp
It's a little faster, but it still takes 3.3 seconds. A little smoother, but
not much.
If I increment the loc in units of ten and set the wait to ten millisecs, it
scrolls in a little less than a second, but it looks jerky and the scroll still
stutters.
I tried various adjustments to the field properties and various ways of writing
the script. For example, I tried eliminating locVar and incrementing item 2 of
the loc itself. Nothing seemed very helpful.
If I remove the "wait x millisecs" the loc scrolls to the bottom instantly.
Can't even see it move. Apparently "wait 1 millisec" waits a lot longer than 1
millisec and the length of the wait is inconsistent.
I thought it might be a graphics rendering problem. The text scrolls in front
of a photo. Hiding the photo doesn't help at all.
This is on a MacBook with 2.4 GHZ Core 2 Duo and tons of physical RAM and OS
10.7.4. Should be fast enough.
Activity Monitor shows that CPU usage gets up to about 40% while the script is
running.
Any thoughts our suggestions? Thanks in advance.
Tim
