Text align

anyone know how to align text in an as3 created text field:

var loadingText:TextField = new TextField();
loadingText.text = ‘Building Interface…’;
loadingText.textColor = 0xffffff;
loadingText.selectable = false;
?? loadingText.textAlign = ‘center’; ??

needless to say that doesn’t work and throws an error, i can’t find for the life of me how to do this if its even possible.

thanks.
