Document Class initialising Application

Question

Hi
I have started learning AS3. One thing I seem to be missing
the point over is the following:
I have a Document Class as follows:
package {
import flash.display.*;
import com.Application;
public class EntryPoint extends Sprite {
public function EntryPoint() {
var app:Application = new Application();
The document class creates an instance of the Application
class
package com {
import flash.display.*;
public class Application extends Sprite{
public function Application() {
var mc_root:Sprite = new Sprite();
addChild(mc_root);
var circleTest:CircleTest = new CircleTest();
mc_root.addChild(circleTest);
CircleTest is a library item that has a class reference of
'CircleTest' and a Base Class of 'flash.display.Sprite'.
I can only get the above working if the code is in the
Document Class.
Help would be greatly appreciated
Thanks

Hi. Without looking closely, I'd think the problem is that
you're adding the circle to the app, but not onto the document
class instance (and neither is app added as a child to your main
class)
so the circle is just in limbo.
You can look at the diagram in Flash Help- under: Basics of
display programming
