	package {
	 import flash.display.Sprite;
	 import flash.events.MouseEvent;
	
	 public class ExampleApplication extends Sprite{
	 private var _sprite:Sprite;
	
	 public function ExampleApplication(){
	 _sprite = new Sprite();
	 addChild(_sprite);
	 _sprite.graphics.beginFill(0xFFFFFF);
	 _sprite.graphics.drawRect(0, 0, 400, 400);
	 _sprite.graphics.endFill();
	
	 _sprite.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
	 _sprite.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);
	
	 }
	 private function onMouseDown(event:MouseEvent):void{
	 _sprite.graphics.lineStyle(1, 0, 1);
	 _sprite.graphics.moveTo(mouseX, mouseY);
	 _sprite.addEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);
	 }
	 private function onMouseUp(event:MouseEvent):void{
	 _sprite.removeEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);
	 }
	 private function onMouseMove(event:MouseEvent):void{
	 _sprite.graphics.lineTo(mouseX, mouseY);
	 }
	 }
	}
