How to get stage width and height in Flex Builder AS3 project

[hieronymous]

I'm using Flex Builder to code an AS3 project that does not use the flex framework. I want to position my elements dynamically based upon the stage width and height. Unfortunately I do not seem to have immediate access to stage properties. The following code shows my problem:

package
{
[SWF(width='800', height='430', backgroundColor='#000000')]
public class app extends Sprite
{
public function app():void
{
trace(stage.stageWidth); //0
}
}
}

Is there an event that gets dispatched when the stage has been created and sized? I've already tried listening for the following events.
Event.RESIZE
Event.COMPLETE
Event.INIT
Event.ADDED_TO_STAGE
FlexEvent.CREATION_COMPLETE
FlexEvent.APPLICATION_COMPLETE

Event.ADDED_TO_STAGE is the only one that gets dispatched, and at that point stage.stageWidth still returns 0.

Are you launching this into a InternetExplorer window?

I've heard of people getting this, and it usually only occurs on IE. I launch into Firefox, and into a standalone swf player and never get this bug.

you can also check the loaderInfo object. But you have to wait for it to be fully loaded first.

I'm actually running it in Firefox 3, on a Mac. I went into my bin-debug folder and ran the html file and was surprised to find it worked in opera and safari.

So I guess the problem is in the way the html template is constructed?

Ok, I probably should have been able to figure this out on my own, but I got the answer at http://hubflanger.com/stage-resize-and-the-stagewidth-and-stageheight-properties/

setting stageScaleMode generates an Event.RESIZE event and updates the stage properties. At that point you can get stage.stageWidth and stage.stageHeight.
