SimpleFormat.as

package text {
  import flash.text.TextFormat;

  public class SimpleFormat extends TextFormat {
    public function SimpleFormat(options:Object):void {
      for(var k:Object in options) {
        if(this.hasOwnProperty(k)) {
          this[k] = options[k];
        }
      }
    }
  }
}

This makes formatting your text a one-liner that you can use keyword arguments for.

Example:

var myField:TextField = new TextField();
myField.text = "some text";
myField.setTextFormat(new SimpleFormat({font: "Helvetica", size: 90, align: "center"}))
