addChild from class

[2slick]

Hi, I'm trying to 'addchild' (a circle shape) to the stage from a class that's not the main project class. Maybe this is a bad idea... I'm not sure. Anyway, my code isn't working, yet there are no errors. Here's it is below. Any suggestions would be appreciated.

package  {
	
	import flash.display.MovieClip;
	import flash.display.Shape;
	
	
	public class main extends MovieClip {
		
		var circle3:Shape = new Shape();
		
		public function main() {
			// constructor code
			
			circle3.graphics.beginFill(0xefefef, 1);
			circle3.graphics.drawCircle(100,100,50);
			circle3.graphics.endFill();
			addChild(circle3);
		}
	}
	
}
