Stage properties in custom class, not Document Class - actionscript-3

Question

I need to use stage.width/height in my CustomClass so I found some topics about it.
if (stage)
{
init(ar,firma,kontakt,oferta,naglowek,tekst,dane);
}
else
{
addEventListener(Event.ADDED_TO_STAGE, init);
}
But in my case it won't work because it isn't document class, I think. Any other solution?
UPDATE:
CLASS CODE

import fl.motion.easing.*;

Hope it will helps.

I expect you are getting an error from the init function which expects lots of parameters but might just get one Event. It helps when you post here if you post the compile or runtime errors you are getting along with source code.
I think this should work for you, I've made a rough version which you can learn from and apply to your own class
public class CustomClass extends MovieClip
{
protected var _company:String;
protected var _data:Object;
public function CustomClass( company:String='', data:Object=null )
{
_company = company;
_data = data;
if (stage)
{
init();
}
else
{
addEventListener(Event.ADDED_TO_STAGE, init);
}
public function init(e:Event=null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
//do something with _data
//do something with _company
}
}
Hopefully you can see the concept here, place your constructor variables in class variables when you create the class, then if on the stage call init() which uses those class variables or add an event listener which will call init(passing in an event this time) and then use the same class variables to do what you want.
Note how I remove the event listener when it isn't needed any more as well.
