checking # of lines in a text field

[deadbeat]

Hi...

I'm building a Flash interface, in which there is a text field large enough to display about 8 lines of text...This field is populated by reading in an external text file...The text files vary greatly in length, from a single word to several paragraphs...

So, I'm wondering if there's a way to check the properties of the text field to find out if the text is longer than the visible area...based on the results of this, I would then set the visibility of a scrollbar movieclip on or off depending whether they were necessary...

Any help appreciated...

if (textfieldname.maxscroll > 8) {
scrollbar._visible=true;
}

Actually, that's wrong, sorry. Maxscroll is the number of lines which do not fit on the page. I don't know if it = 0 when everything fits on the page, but something more like this would work...

if (textfieldname.maxscroll > 0) {
scrollbar._visible=true;
}

Or maybe > 1...

Thanks!

Figured it was probably about that easy, just wasn't sure how to go about it...

Cheers,
