Your second one is a poser. The formatted widths and heights do not help, I
think, if you do not already have the field populated with text. You are asking
for the "potentialFormattedWidth", essentially.
Without using a monospaced font like courier, I would not know how to begin. If
you did use such a font, though, you could calculate the number of chars and
lines that would fit, based on the rect of the field. I made a field in courier
12. I know how many chars per pixel width I can fit, and how many lines I can
fit as well. A simple function will give the number of chars for any field
size. Once you have that, you can trap keydown to limit the total char count.
But someone smarter will have to answer for dynamically spaced fonts. Maybe
this is a start?

Subject: Allowing user to change size and location of a field
Hello,
I would like to allow a user to be able to change the size and location of
a text field in an application.
The following allows the user to select the field via right-shift click and
then with the pointer tool move the field to where they want and resize the
field.
With the next right-shift click the field is deselected and the browse tool
is shown.
Problem is the user cannot put text into the field anymore?
Am I approaching this correctly?
on mouseDown theButton
if theButton is 3 AND the shiftkey is down then
get the selected of me
switch it
case "true"
set the selected of me to false
set the tool to browse
select empty
break
case "false"
set the selected of me to true
set the tool to pointer
break
end switch
else
pass mouseDown
end if
end mouseDown
Another question which may not be able to be answered is... can you limit
the number of characters in the field based on the new size the user has
made?
thanks,
Glen
