AS3 Sprite added to Stage but not visible

I'm trying to get a simple AS3 app up and running, and for some reason, I cannot get a sprite to show. At this point, all I want to do is get a red sprite to fill the stage.

public class Main extends Sprite 
    public function Main():void 

        stage.scaleMode = StageScaleMode.NO_SCALE;
        stage.align = StageAlign.TOP_LEFT;

        var square:Sprite = new Sprite();   

        square.width = stage.stageWidth;
        square.height = stage.stageHeight;
        square.x = square.width / 2;
        square.y = square.height / 2;;, 0xFF0000);;, 0, width, height);;

        square.addEventListener(Event.ADDED_TO_STAGE, addedToStage);
        square.addEventListener(MouseEvent.CLICK, onClick);


     private function addedToStage(e:Event):void 
          trace("Added sprite to stage");           
     private function onClick(e:Event):void 
          trace("Got click on sprite");         

The trace shows that the sprite was added to the stage, but nothing is displayed, and if I click on it, the onClick function never gets called. If I use a TextField instead of a Sprite, it displays just fine. There must be something weird about Sprites.

What am I doing wrong?



Trying to set the width and height for a empty Sprite will return 0. Have a look at here.


Refer Mr.Marty Wallace's answer.

Your issue is here:, 0, width, height);

The values for width and height in this line are 0. The reason being that they are referring to the width and height properties of the class you're working within (Main - properties inherited from DisplayObject) which will be zero based on what I can see.

You're essentially saying:, 0, 0, 0);

Which will render nothing.
