actionscript 3 MVC work flow

Answer 1

Create a variable inside your View class called:

var main:Main;

Then a function to receive an object of type Main that sets the variable you created above, like this:

public function setMain(mainIN:Main):void
{
   main = mainIN;
}

Now you have a local copy of all the data contained in your main document class in your View class. You can access properties of main by doing this (inside your view class' functions):

main.model.x = mouseX; //just an example. For this, your model variable inside Main would need to be public.

To do data passing the other way, you simply create public properties or functions inside your View class, and then because you've created the instance of View inside your Main class, it will be able to access it as normal with code like:

view.someViewFunction();

In this way each class has access to each other's properties and functions. I hope this helps!

Answer 2

I generally handle communication by changing properties in the model via the controller. On change of values in the model, i will dispatch events representing those changes. Anyone (Main in this case) that has a reference to the model can subscribe to those events. This results in a more circuitous implementation, but to a very loosely coupled result.
