[RESOLVED] Key event assigned in class not working

[somlemeg]

My script has a structure like this (shorten down version):

MenuDisplay.as (creates the menu)

package
{
    import flash.display.Graphics;
    import flash.display.BitmapData;
    import Array;
    //
    import flash.display.Sprite;
    import flash.text.TextField;
    import flash.text.TextFormat;
    import flash.display.Graphics;
    import flash.display.Sprite;
    import flash.events.MouseEvent;
    import flash.events.KeyboardEvent;
    
    public class MenuDisplay extends Sprite
    {
        public function makeMenu () : void
        {
            addChild (menuAct);
            // make the menu here
        }
        // functions for creating the menu items here...
    }
} 

For making it easier to navigate the code I moved the functions for the buttons into a new class MenuActions.as:

package
{
    import flash.display.Graphics;
    import flash.display.BitmapData;
    import Array;
    //
    import flash.display.Sprite;
    import flash.text.TextField;
    import flash.text.TextFormat;
    import flash.display.Graphics;
    import flash.events.MouseEvent;
    import flash.events.KeyboardEvent;
    import flash.display.Sprite;
    //import flash.display.Stage;
    import flash.display.*;
    import flash.events.*;

    
    public class MenuActions extends Sprite
    {
        var backgroundNoise = new StaticNoise ();
        // Functions for menu items
        public function startProgram (e : MouseEvent) : void
        {
            backgroundNoise.CreateStaticNoise ();
            addChild (backgroundNoise);
            // Set focus to stage
            backgroundNoise.addEventListener (KeyboardEvent.KEY_DOWN, backgroundNoise.checkKey);
        }
    }
} 

The problem here is that the keys are not picked up. Earlier when I had the code in the MenuDisplay class, everything worked fine by doing:

            addChild (backgroundNoise);
            stage.addEventListener (KeyboardEvent.KEY_DOWN, backgroundNoise.checkKey);
            // Set focus to stage
            stage.focus = stage; 

but the stage is null, and if I try Stage.addEventListener... or Stage.focus, I receive an error.

as an weekend coder, I'm not sure if I'm structuring my code right

Solved it by using:

            this.stage.addEventListener (KeyboardEvent.KEY_DOWN, backgroundNoise.checkKey);
            this.stage.focus = this.stage;
