How to hide partial lines in a TextArea

I am using a TextArea component and programatically assigning some text to it.  Sometimes, the last line does not fit into the given width and height of the control.  Is there any way I can not show any lines that are partially displayed?

Any advice is welcome.

Thanks,

Om

TextGraphicElement, the superclass of SimpleText and RichText, has an isTruncated():Boolean method.

It should report the correct value after the updateComplete event has been dispatched. If it isn't working, can you please file a bug at http://bugs.adobe.com/flex/?

<s:TextArea> is designed to make it possible for a user to scroll through a large amount of text and doesn't have an option for showing only the lines that completely fit. But if you don't need scrolling, selection, or editing, you could use <s:RichText truncation="-1"> which would show you only the lines that fit.

Gordon, that worked, thanks!  Is there any flag I can check to find out if a truncation has ocurred?  Or any event that I can listen to?

Thanks,

Om
