Interesting... I missed the getCharAtIndex method...

But, I guess I'm a little confused about your example, where do the values "300" and "40" come from?

Another problem is that I can't really "hardcode" an x, y point to check because different fonts and characters will take up different amounts of space within the text field... so if I say "I'm always going to check this x,y point", there's no garauntee that a character will be in at that point. Also, if the text box isn't quite tall enough to fit an entire line, Flash won't display half a line of text, so it'll just not display that line, and there will be a larger margin between the last visible text and the bottom of the Text Field.

Now, the text field's width and height WILL NOT change... so I guess I need a way to dynamically calculate the x,y point using the text field's width/height/format and any other metrics I have access to.

I suppose I could start checking if there is a character exactly at the bottom-right corner of the Text Field (which there never will be), and then just start moving the x,y point incrementally towards the top-left corner of the Text Field until I run into a character?

Is that a viable solution?

It seems the TextLineMetrics object offers a lot of metrics to use... would any of those be helpful??
