Hello Everyone,
I am new to design patterns and am trying to learn the MVC implementation. I have written four classes:
DataModel
DataView
DataController
Main
Main serves as the application facade. The main FLA is called HelloWorld. I have a symbol called "Box" in HelloWorld. I just would like to add an instance of the "Box" on the stage. Eventually I would like to place a button and when the button is clicked, the Box instance color will be changed. I would appreciate any help, please help me figure out what am I doing wrong.
Here are my Classes:
DATAMODEL CLASS:
package
{
import flash.events.*;
public class DataModel extends EventDispatcher
{
public static const UPDATE:String = "modelUpdate";
private var _color:Number = (Math.round(Math.random()* 0xffffff));
public function DataModel()
{
trace("DATA MODEL INIT");
}
public function get color():Number
{
return _color;
}
public function set color(p:Number):void
{
_color = p;
notifyObserver();
}
public function notifyObserver():void
{
dispatchEvent(new Event(DataModel.UPDATE));
}
}
}
//DATACONTROLLER CLASS:
package
{
import flash.events.;
import flash.display.;
import flash.errors.*;
public class DataController
{
private var _model:DataModel;
public function DataController(m:DataModel)
{
trace("DATACONTROLLER INIT");
_model = m;
}
}
}
DATAVIEW CLASS:
package
{
import flash.events.;
import flash.display.;
import flash.errors.*;
public class DataView extends Sprite
{
private var _model:DataModel;
private var _controller:DataController;
private var b:Box;
public function DataView(m:DataModel, c:DataController)
{
_model = m;
_controller = c;
b = new Box();
b.x = b.y = 100;
addChild(b);
}
}
}
And Finally THE FACADE:
package
{
import flash.display.;
import flash.events.;
import flash.text.;
import flash.errors.;
public class Main extends Sprite
{
private var _model:DataModel;
private var _controller:DataController;
private var _view:DataView;
public function Main(m:DataModel, c:DataController, v:DataView)
{
_model = m;
_controller = c;
_view = v;
addChild(v);
}
}
}
When I test the movie: I get this error:
ArgumentError: Error #1063: Argument count mismatch on Main(). Expected 3, got 0.
Thanks alot.
