package druva {

 import flash.display.*;

 public class drawCircle extends Sprite {

 public function drawCircle() {
 var canvas:Shape = new Shape(  );
 canvas.graphics.lineStyle(3, 0xFF0000);
 canvas.graphics.drawCircle(100,100,50);
 addChild(canvas);

 }
 }
}

This is another way of rotation related to my previous post

Rotation changes depending on the mousex position

rotator.addEventListener(MouseEvent.MOUSE_DOWN, initialize);
rotator.addEventListener(MouseEvent.MOUSE_MOVE, mouseMover);
rotator.addEventListener(MouseEvent.MOUSE_UP, deinitialize);

var dragging;
var actual_rotation;
var mouse_pos;

function initialize(evt:Event){
 mouse_ref = mouseX;
 dragging = true;
 actual_rotation = rotator.rotation;

}

function mouseMover(evt:Event){
 if(dragging){
 rotator.rotation = actual_rotation + (mouseX - mouse_pos)* 3;
 }

}

function deinitialize(evt:Event){
 dragging = false;
}
