Set font dynamically to fit text

[Dan Friedman]

Sannyasin,

I've been doing this for years.  Works well...

on doShrinkToFit lFldID,startingSize,minSize
  set the textSize of lFldID to startingSize
  repeat until the formattedHeight of lFldID <= the height of lFldID
    set the textSize of lFldID to (the textSize of lFldID - 1)
    if the textSize of lFldID < minSize then
      exit repeat
    end if
  end repeat
end doShrinkToFit

Of course, the moment you start with this type of work, you'll immediately wish LiveCode would support fractional font sizes!

Hope that helps...

-Dan

    Assuming one is not putting whole pages into small fields, does any one have an efficient run time LC algorithm that will set the font size so that the formatted text will all appear in the field without needing to scroll?
