RE: [Flashcoders] Seek MVC Menu
Thankx for the overview Michael...I'm really hoping to find a fleshed out,
workable version I can tear apart.
I suppose it wouldn't have to be a menu per se...but it sure seems like a
creature such as this would have been tutorialized.

Kind of depends on what your states and actions are. Here's a good basis:
/**
* Model class that stores data for one menu item.
f *
* pOptionally has child items./p
*/
class menu.MenuItem {
/**
* Label for this item.
*/
public function get label():String;
/**
* Number if child items (nonnegative integer).
*/
public function get childCount():Number;
/**
* Retrieves a child item.
*
* @param index Index of child item, nonnegative integer less
than [EMAIL PROTECTED] #childCount}.
*/
public function getChild(index:Number):MenuItem;
/**
* Reads data from an XML node.
*
* @param node XML node with menu item data.
* @throws Error If [EMAIL PROTECTED] node} is not properly formatted.
*/
public function readXMLNode(node:XMLNode):Void;
}
import menu.MenuItem;
import mx.events.EventDispatcher;
[Event(currentChange)]
/**
* Controller class that keeps track of the currently-selected item.
*/
class MenuController extends EventDispatcher {
/**
* Currently-selected menu item.
*/
[Bindable(event=currentChange)]
public function get currentItem():MenuItem;
public function set currentItem(item:MenuItem):Void;
}
import menu.MenuController;
import menu.MenuItem;
/**
* Menu item component.
*/
class menu.MenuItemView extends MovieClip {
/**
* Creates a new instance referring to a specific item.
*
* @param parent Parent movie clip.
* @param controller Object that controls the menu.
* @param item Menu item model object.
* @return New instance of this class.
*/
public static function create(parent:MovieClip,
controller:MenuController,
item:MenuItem):MenuItemView;
/**
* The item that this component refers to.
*/
public function get item():MenuItem;
}
MenuView components could then listen to MenuController.instance for
currentChange events and update whether or not they are enabled or
disabled. Further attributes could be added to MenuItem (id, type,
selectable, whatever). MenuController could also be used to keep track
of other things. It might also be a good idea to create a Menu class
for containing top-level MenuItem objects, with a corresponding
MenuView class for containing top-level MenuItemView object.
There are a lot of different things you could do with this basic MVC
setup, depending on what you need.

Well, as long as you understand: - private variables, and how they may be used as a basis for properties; - using the XMLNode class; - the event dispatcher model, and the MX implementation thereof; - static vs. instance functions; - and symbol registration; ... you should be able to use the skeleton I outlined in my previous post. If you're not familiar with one of them, I'd look for a tutorial on that. -- T.
