as3 use setter in other class(parent) - actionscript-3

Question

I'm trying to make a simple setter which i like to access with a child class.
Here is the parent class code :
public class DeGeheimeMissie extends MovieClip
{
var deLader:URLLoader;
var deXmlData:XML;
public var hoofdVragenLijst:Object = new Object();
public var subVragenLijst:Object = new Object();
public var hetAntwoord:String;
public function DeGeheimeMissie()
{
var hetVerzoek:URLRequest;
hetVerzoek = new URLRequest("dialogen.xml");
deLader = new URLLoader(hetVerzoek);
deLader.addEventListener(Event.COMPLETE, vragenGeladen);
deLader.load(hetVerzoek);
instObama.addEventListener(MouseEvent.CLICK, showVragen);
instObama.buttonMode = true;
instObama.useHandCursor = true;
}
public function set hetAntw(str:String):void
{
hetAntwoord = str;
}
and here is the child class where i try to access it:
public class Rutte extends MovieClip
{
var deLader:URLLoader;
var deXmlData:XML;
public var antwoordenOverzicht = [];
//constructor
public function Rutte()
{
var hetVerzoek:URLRequest;
hetVerzoek = new URLRequest("dialogen.xml");
deLader = new URLLoader(hetVerzoek);
deLader.addEventListener(Event.COMPLETE, antwoordenGeladen);
deLader.load(hetVerzoek);
instRutte.addEventListener(MouseEvent.CLICK, showAntwoorden);
instRutte.buttonMode = true;
instRutte.useHandCursor = true;
}
public function setAntwoord(e:MouseEvent)
{
var antw = e.currentTarget.text.charAt(0);
trace(e.currentTarget.text.charAt(0));
this.parent.hetAntw(antw);
}
The error i get here is:
1061: Call to a possibly undefined method hetAntwoord through a reference with static type flash.display:DisplayObjectContainer.

Answer 1

You should try this, this is how we use setters :
this.parent.hetAntw = antw;
But why making a public setter on a public static var ?
