Question

Is there a function or property or better way to do what the following code do?

var width:int = 20
while (textField.defaultTextFormat.size > 1 && textField.width > width) {
    textField.defaultTextFormat.size--
}

Answer 1

There is no built-in method for that. Another way, depending on what you’re trying to do, would be to scale the textfield so that it fits within the required width:

var scale:Number = targetWidth / textField.textWidth;
textField.scaleX = scale;
textField.scaleY = scale;
