Question

Using Adobe Flash Professional CS6, AS3
Please let me know if I need to provide any more info
I am trying to set up a navigation menu and my question is, “How do I get a MovieClip to call a function in my Main.as file from the Stage?” There is only one frame (I do not want more) and the different menu screens, which are just MovieClips, are added to the stage with AS when needed. I have a public function in the file Main.as called _About(), that my MovieClip, “MenuScreen”, cannot access. I can successfully have _Menu() add a MovieClip to the stage with eventListeners, but when the mc makes the call back to change screens I get this error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@51ca0d1 to flash.display.MovieClip. at MenuScreen/clickAbout()[MenuScreen::frame1:32]

Frame1:32’s code is:

MovieClip(parent)._About();

Line 51 in my Main.as is:

public function _About():void
{
trace("The About Function");
}

Below I have detailed more about Main.as with most of the fat trimmed.

package 
{
import stuff

public class Main extends MovieClip
{
    //Load the screen MCs onto the stage
    public var _menu:MenuScreen = new MenuScreen();
    public var _about:AboutScreen = new AboutScreen();
    public var isMenu:Boolean = true;
    public var isAbout:Boolean = false;

    public function Main()
    {
        _Menu();            
    }

    public function _Menu():void
    {
        isMenu = true;
        stage.addChild(_menu);
    }

    public function _About():void
    {
        trace("The About Function");
    }

Set static property :

public static var instance:Main;
public function Main(){
        instance = this;
        _Menu();            
    }

and then from anywhere You can use code :

Main.instance._About();
