[flexcomponents] Canvas dropShadow

[Firdosh Tangri]

Can an empty Canvas( with backgroundColor)  have a dropShadow or corner
radius effect

var aboutMe:Canvas=new Canvas();
   aboutMe.width=this.width*(2/3);
   aboutMe.height=this.height*(2/3);
   aboutMe.setStyle("backgroundColor",0x333333);
   aboutMe.setStyle("dropShadowEnabled",true);
   aboutMe.setStyle("shadowDistance",3);
   aboutMe.setStyle("shadowDirection","right");
   aboutMe.setStyle("cornerRadius",6);

   aboutMe.x=(this.width/2) - (aboutMe.width/2);
   aboutMe.y=(this.height/2) - (aboutMe.height/2);
   mainCnvs.addChild(aboutMe);

I cannot see the shadow no matter what I do ,
nor can I see the corner radius




thanks
cheers :)
