Hello.
I once used something similar to what Bob suggested. (Though I should
look at Bob's "line" solution to see if it won't work better.) The
following doesn't work perfectly in all cases... but perhaps it will
provide an idea.
-- this goes in the field
on rawKeyUp
FieldLimiter -- don't allow typing past the visible bottom of the
field
pass rawKeyUp
end rawKeyUp
-- this goes somewhere in the message path of the field(s)
on FieldLimiter -- don't allow typing past the bottom of fixed-sized
fields
if (the textheightsum of the target) > (the height of the target +
12) then -- 12 is a "slop" factor
if (word 4 of the selectedChunk) < (the num of chars of the
target) then
-- they are in the middle of the text somewhere so don't
delete characters off the end
-- play the uAlertSound of stack "Hidden"
exit FieldLimiter
end if
-- they are typing at the end of the text chunk... don't let
them insert characters
delete last char of the target
-- play the uAlertSound of stack "Hidden"
repeat 5 times -- 5 is arbitrary
if the textheightsum of the target < (the height of the target
+ 12) then
exit repeat
end if
delete last char of the target
end repeat
set the scroll of the target to 0
end if
end FieldLimiter

Hi,
If the field height is divided by the textHeight, the result is the
number of lines.
You can then limit the number of lines.
See textHeight and keyDown in the docs. Don't know if the spacebar
can be used with keyDown.

Hi there,
I made a field which is 500(width) x 530(height) pixels and now I am
looking for a way to limit the text input in this field based
upon the
height of the field.
I dont want more text than the height of the field.
If you set the autoTab of a field to true, when the user gets to the
last line and presses Return or Enter, it will be as if they pressed
Tab to go to the next field. They won't be able to enter more lines
than are visible.
Cheers,
Sarah
