Calculating Text Width In ActionScript And Flex

Question

I\'m trying to calculate how WIDE to make my button, based on the text that it will contain, and when I try to google for how to calcuate something as simplistic as the WIDT

Answer 1

as I think, textField.textWidth construction works fine... until you change the font size. It seems it calculates width based on 12px font. So, if you have embedded font and global styling you can try fast solution:

var realWidth = myLabel.textField.textWidth * (fontSize / 12);

I've tried this on long and short strings and the result is correct.
