[flexcoders] fit text width & height to amount of text

[Paul Hastings]

i'm having another newbie flex brain fog ;-) trying to set up a
background color for a TextField that is more or less the width &
height of the it's text. i've tried looping thru the text looking at
TextLineMetrics but i still end up w/text backgrounds that are too
wide, something along the lines of (where [ ] represent the
background):

[test text     ]

any suggestions?

thanks.
