Line length

[Dan Friedman]

Bob,

I do what you're talking about all the time.   Here's my setObjectHeightToText command that I use (pass it the long id of the field, and the minimum height you want):

on setObjectHeightToText lID,minH
  put the rect of lID into tRect
  put item 2 of tRect + the formattedHeight of lID into item 4 of tRect
  if minH > 1 then
    if item 4 of tRect - item 2 of tRect < minH then
      put item 2 of tRect + minH into item 4 of tRect
    end if
  end if
  set the rect of lID to tRect
end setObjectHeightToText

Hope that helps!

-Dan

    I have a field on one of my apps whose width needs to change depending on content, but there is a minimum and a maximum width aspect, so that an empty field doesn’t appear like a weird tiny rectangle or stretch to overlap other objects. 

    I use something like:

    if the formattedWidth of field x < tMinWidth then set the width of field x to tMinWidth
    else if the formattedWidth of field x > tMaxWidth then set the width of field x to tMaxWidth
    else set the width of field x to the formattedWidth of field x
