TextArea uses TextField to render the text characters. If you look at the livedocs ( http://livedocs.adobe.com/flex/201/langref/flash/text/TextField.html), you'll see a lot of useful methods and properties. There are probably a couple ways to do this. I would iterate through the lines of text using getLineMetrics() and check to see if the line was inside the bounding box of the TextField. The character before that line should be the last character shown. Note that I'm not sure if you're going to care about the position of the top of each line, or the bottom of each line. You'll have to test things like that for yourself. To get to the textField of a TextArea you can either subclass the TextArea or use textArea.mx_internal::getTextField(). (for more information on mx_internal see http://nondocs.blogspot.com/2007/04/mxcoremxinternal.html)
