traditional vanilla MVC tends to use composition like the example given,
check out robotlegs if you don't like it :) then you inject dependencies
instead of passing them around and everything gets a bit more loosely
coupled...
It's not a question of not liking it - your example is perfect for a
coded-only solution, slightly less practical when working in a
mixed-mode with the Flash IDE being involved in view instantiation.

Excellent job.
I have one small point, on a practical level.
For the views, in particular, I don't usually pass arguments to the
constructor. It's not such a big deal for code-only examples, but in my
flash world I mix my components between stuff created dynamically and
things created in the IDE - sometimes I build components as assemblies on
the stage using the IDE. The point is that passing arguments to the
constructor then becomes an issue for a view.
Might I suggest an init() function to pass in Model and Controller?

Subject: Re: MVC
feel free to hit me up any time ill try to have time to respong
none the less, this should get you started:
/*
* Model.as
*
* mvc.Model;
*/
package mvc {
import flash.events.EventDispatcher;
import flash.events.Event;
class Model extends EventDispatcher{
private var _count:int = 0;
public function get count():int{
return _count;
}
public function set count(value:int):void{
this._count= value;
update();
}
public function Model(){
super()
}
private function update():void{
this.dispatchEvent(new Event(Event.CHANGE));
}
}
}
/*
* Controller.as
*
* mvc.Controller;
*/
package mvc {
public class Controller {
private var model:Model;
public function Controller(model:Model){
super()
this.model = model;
}
public function countUp():void{
this.model.count++;
}
}
}
/*
* View.as
*
* mvc.View;
*/
package mvc {
import flash.text.TextField;
import flash.events.Event;
import flash.display.Sprite;
public class View extends Sprite(){
private var model:Model;
private var controller Controller;
private var textField:TextField = new TextField();
public function View(model:Model, controller:Controller){
model.addEventListener(Event.**CHANGE,
this.model_changeHandler);
super()
this.model = model;
this.controller = controller;
this.addChild(this.textField);
this.stage.addEventListener(**MouseEvent.CLICK,
this.stage_clickHandler)
}
private function stage_clickHandler(event:**
MouseEvent):void{
this.controller.countUp();
}
private function model_changeHandler(event:**Event):void{
this.textField.text = this.model.count
}
}
}
/*
* App.as
*
* MVC screen click counter.
*/
package{
import mvc.Model;
import mvc. View;
import mvc.Controller;
public class App{
private var model:Model = new Model();
private var controller:Controller = new
Controller(this.model);
private var view:View = new View(model, controller);
public function App(){
this.addChild(this.view);
}
}
}
Now imagine a Model with more properties.
And tons of different Views of them that data.
Some of which provide a UI linked to Controller methods that manipulate
it.
