Adding Icons 2 Buttons

Hello,

I am going over the optional buttons in AS3, and I have found the SimpleButton (flash.display.SimpleButton) and Button (fl.controls.Buttons).

I can not see a property that presents an icon of type PNG or ICO or even Bitmap… Maybe I missed something.

How do you add an icon to a button? Or should I just place a MovieClip with a click event listener?

Thanks,
OML
