var i:Circle = new Circle(mc);
///////////////////////////////////
Circle.as里
class Circle extends MovieClip {
       public function Circle(mc:MovieClip) {
              drawRectangle(mc, 100, 100, 0xff0000, 100);
       }
       private function drawRectangle(target_mc:MovieClip, boxWidth:Number, boxHeight:Number, fillColor:Number, fillAlpha:Number):Void {
              with (target_mc) {
                     beginFill(fillColor, fillAlpha);
                     moveTo(0, 0);
                     lineTo(boxWidth, 0);
                     lineTo(boxWidth, boxHeight);
                     lineTo(0, boxHeight);
                     lineTo(0, 0);
                     endFill();
