I haven't tested this but for 4 I would assume something similar to the following should work.
var sometext:UITextField; sometext.styleName = UITextField in your style sheet you should be able to now set styles and the font, UITextField{ fontFamily: ...; } if you call it UITextField you may not have to assign the styleName. I probably don't have all of this right but it should at least help you get in the right direction. > 4. How do I set the font of UITextField with stylesheet, or embedded > font
