Views listening for events from the global EventDispatcher

[Marcelo de Moraes Serpa]

Hello list,

I've got the classic pixlib MVC architecture.

I've got a command that is called at the init of the application to load some data from a XML. The event, listed in the EventList is called LOAD_XML. In order to perform some user interface changes, I want some views to listen for this event. However, I'm not sure where I should add the views as listeners for the global EventDispatcher. For now, I'm doing this in the main Application's class constructor:

   public function Application ( target )
   {
       (...)
       var vBottomBar:ViewBottomBar = new ViewBottomBar(this.bottom_bar_mc);
       var vContent:ViewContent = new ViewContent(this.content_mc );
  
       EventDispatcher.addListener(vBottomBar);
       EventDispatcher.addListener(vContent);

       EventDispatcher.dispatchEvent( new BasicEvent( EventList.LOAD_XML ) );


And then I implement a onLoadXml in each of the views. It works fine and seems to be a good design. I could also get a reference for each view in the LoadXML command and call the method directly. What do you think?

Marcelo.

Putting the config data in a model and updating that from the loadxml
command's onResult would work too.
