How-To/Sample code to tie up class variable to MXML component created in Design view

Question

This is a very noob question but I've been searching through the documentation for the last 2 hours and can't seem to find anything helpful.  I have a SWFLoader created in the design view.  I have all my app code in an <fx:Script> with all my functions and variable in a CDATA tag.  All I want to do is hookup the SWFLoader created in the design view with a private var in my ActionScript. 
I also have two separate states for my app, and I want the same SWFLoader to be visible in both states. Can someone point me to some useful sample code or documentation??
Any help is much appreciated.

Sun has recommendations for naming conventions. Class names should start with a capital letter. You should avoid using class names that are the same as classes provided in the SDK. Following these conventions will make it easier for people to help you. For example, you should not use file, nor should you use File. It's better to use MyFile, replacing My with something that makes sense to your application (SeniorFile?).
Also, check the Formatting Help link when posting for a desciption on how to use the code tags for posting code.
1. You need to establish references between your classes. One way is to have a constructor that has a JMenuBar argument.
2. You can not add a file to a JMenuBar because a JMenuBar adds a JMenu. I don't think you want file to extend JMenu. It may be better for file to have a JMenu.
I haven't tried to compile this code so no guarantees - just trying to show you an approach.
public class Senior extends JFrame {
   public Senior() {
      JMenuBar bar = new JMenuBar();
      MyFile file = new MyFile(bar);
//whatever else you need
public class MyFile {
   public MyFile(JMenuBar mbar) {
      JMenu menu = new JMenu();
      mbar.add(menu);
