Unless someone has created this control for public use, you're going to have to subclass the TextArea and create your own. TextArea's use the UITextField class to render text so take a look at http://livedocs.adobe.com/flex/201/langref/flash/text/TextField.html.
I'd say the easiest way is this (all operations acting on the textField, not the TextArea): onKeyDown: cache the current data in htmlText. onChange: measure the new text to see if it overflows the visible area of the TextField. If it does, reset the htmlText to the cached version, else do nothing. end of algorithm. - Dan Freiman On 10/15/07, Michael H.
