Allowing user to change size and location of a field

[dunbarx at aol.com]

What Jacque is saying is to load the formatted height, maybe into a custom property, right after you resize. Then, as the user types, check the current formattedheight, at each keystroke, and if it exceeds the initial value, disallow that text entry.


I played around with this too, etting a custom property to the formattedHeight upon resizing, but ran up against a wall if the field is made smaller. Then the text already is too full for it.


Jacque will find a way, though.

What I usually do is trap keydown and check the formattedheight while 
the user is typing. If the text is too long then either truncate it or 
warn the user some other way. If the field has just been resized, then 
check the formattedheight after the resizing and take action if the 
contents are too long.
