Flash Dynamic Text Width

Question

Hey! I try to find out the text size of a textfield in the following example

field.text = 'aaaaaaa';
trace(field.textWidth);

setTimeput(function(){
   field.text = 'aa';
   trace(field.textWidth);
},2000)

The number is always the same. Why? I need the text width so I can adjust size for a background movieclip. Thx!

Try setting the `autosize` to `left` and reading the text field's `width` instead. — Amarghosh, Nov 25 '09 at 13:00

You might want to try the TextLineMetrics class. It could get you close enough. I've used it a few times and its accurate.

You also have a typo on line 4. "setTimeput" instead of "setTimeout."
