Accessing the Document class in AS3

Question

How can instantiated classes access the Document class?

Even after I name the Document class using the Properties bar in Flash, att

You can use a singleton for your document class (Main, in your example), which allows you to access the instance from anywhere.

public class Main extends Sprite {
    private static var _instance:Main;
    public static function get instance():Main { return _instance; }

    public function Main() {
        _instance = this;
       // etc...
    }

    // etc...
}

Then you access the Main instance like this:

public class Other {
    public function Other() {
        Main.instance.usefulInstanceMethod();
    }
}

The document class is a pretty good candidate for the singleton pattern, because generally there should only be instance available.
