Question

Here’s a very simple AS3 project consisting of one class which draws a rectangle. When I run it, the rectangle is clearly larger than 100×100 pixels. After pulling out my hair for a few hours I thought I’d ask: why?

Edit: I know that it isn’t correct because, though I have my screen resolution set to 1280×800, if I set the width to 500 it takes up almost all of my screen.

package
{
import flash.display.Sprite;
import flash.events.Event;

public class Draw extends Sprite
{
    private var screen:Sprite;

    public function Draw():void 
    {
        this.addEventListener(Event.ADDED_TO_STAGE, stageHandler);
    }

    private function stageHandler(e:Event):void{
        screen = new Sprite();
        screen.graphics.clear();
        screen.graphics.beginFill(0x333333,.9);
        screen.graphics.drawRect(0,0,100, 100);

        screen.graphics.endFill();
        addChild(screen);
        trace(stage.width + "," + stage.height); 
    }
}
}

Somehow your scalemode settigns for your flash player are set in a strange mode from FlashBuilder.

Try setting

stage.scaleMode = StageScaleMode.NO_SCALE;

in your stageHandler function. You code has no errors. The problem is in your publish preview settings somewhere.
