Access main stage from class definition file (as3) - actionscript-3

Question

I'd like to access the stage of the main timeline from w/i a class that extends a movieclip. Basically, I have a button in the main timeline that makes a HUD appear. The HUD is an extended MovieClip class. When people click on a button in the HUD, I'd like to remove the object from the stage of the main MovieClip.
#curro: I think your confusion may come from the fact that I am running this code from a class definition file. Clicking on a button w/i this object should remove it from the DisplayList of the MainTimeline. Here's the code from the class definition file:
package classes {
import flash.display.Stage;
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class Answers extends MovieClip {
public function Answers(){
listen();
}//constructor
//initiatlize variables
public var answersArray:Array = new Array();
private function listen():void {
submit_btn.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){
answersArray.push(answer_txt.text);
e.currentTarget.parent.parent.stage.removeChild(this);
});//listen
}//listen
}//class Definition
}//package
trace(e.currentTarget.parent.parent) gets me the MainTimeline, and trace(e.currentTarget.parent.parent.stage) appears to return the main stage, but I cannot use removeChild w/o getting an error that I am trying to coerce the stage to be a DisplayObject (which it ought to be).
What's on the stage of the MainTimeline: A single button that, when clicked, adds an instance of the Answers class to the stage.
What's part of the Answers class that's not in the code?
I first created Answers as a MovieClip object in the main library. It has 3 parts:
a TextField named "answer_txt"
a "clear_btn" that clears the answer_txt
a "submit_btn" that submits the text of answer_txt and then removes the entire Answers object from the MainTimeline (at least, that's what I want it to do).

Answer 1

your class definition is really weird. Looks like a mixture of as2 and as3.
Try with this:
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.text.*;
import fl.controls.Button;
public class Answers extends MovieClip
{
public var answersArray:Array = new Array();
public function Answers()
{
submit_btn.addEventListener(MouseEvent.CLICK, remove);
}
private function remove(e:MouseEvent)
{
answersArray.push(answer_txt.text);
this.parent.removeChild(this);
}
}
}
This works on my computer. Your code doesn't. I think it has something to do with the listen method. The class isn't still instatiated and you are making it work.

Answer 2

Hey, I can't make head or tail from the code. Where does submit_btn come from? Is it a property of the class? What about answer_txt?
You don't need to access e.currentTarget... to remove "this" simply:
this.parent.removeChild(this);

Answer 3

If you add that movieclip to the stage then you can access the stage from that class as simple as in the document class
stage
Otherwise you can't access stage from that class. But you can access it by sending the stage as argument when instantiate the class.
