Problem accessing .stage from an external class

programming flash
1

Hello!

I’ve done a very simple fullscreen test application which worked while everything was in the document class. Now I want to try having the fullscreenswitch-code in an external class but I get an “1120: Access of undefined property stage.” error.

Sorry if this is a really dumb question (I’m new to flash/as3/and the process of working with classes) but how do you access stage from an external class? :puzzled:

This is the document class

package com {
    import flash.display.Stage;
    import flash.events.Event;
    import flash.display.StageScaleMode;
    import flash.display.StageAlign;
    import flash.display.MovieClip;
    import flash.text.TextField;
    import flash.text.TextFieldAutoSize;
    import flash.events.TextEvent;
    import com.FullscreenSwitch;
    
    public class FullscreenTest extends MovieClip {
        
        // Constants:
        // Public Properties:
        public var txtFullscreen:TextField = new TextField();

        // Private Properties:

        // Initialization:
        public function FullscreenTest() {
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align = StageAlign.TOP_LEFT;
            
            txtFullscreen.multiline = true;
            txtFullscreen.autoSize = TextFieldAutoSize.LEFT;
            txtFullscreen.htmlText = "<p><a href='event: aaaaaa'>Fullscreen</a></p>";
            txtFullscreen.x = 12;
            txtFullscreen.y = 12;
            addChild(txtFullscreen);
            
            txtFullscreen.addEventListener(TextEvent.LINK, FullscreenSwitch);
        }        
    }
}

And this is the fullscreenSwitch which is called upon from the documentclass

package com {
    import flash.display.Stage;
    
    public class FullscreenSwitch extends MovieClip{
        
        // Constants:
        // Public Properties:
        // Private Properties:
    
        // Initialization:
        public function FullscreenSwitch() {
            switch(stage.displayState) {
                case "normal":
                    stage.displayState = "fullScreen";
                    break;
                case "fullScreen":
                    default:
                    stage.displayState = "normal";
                    break;
            }
        }
        // Public Methods:
        // Protected Methods:
    }
}

http://www.kirupa.com/forum/showthread.php?p=1952513 seems to be the solution to the problem but I’m not sure how to explicitly give a reference to a non-display object classes…
