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

So long as you're in a UIComponent, you can use the measureText function.

public function howWideWouldThisTextBeIfItWereInThisButton(text:String,container:Button):int {
   var lineMetrics:TextLineMetrics = container.measureText(text);
   return lineMetrics.width;      
}

That being said, the flex button component should automatically size to the width of the text, if you don't set a width on it. That way if you need the text width, you can just call use the textWidth property.
