[flexcoders] Re: dispatchEvent import
Actually, you weren't wrong. It seems that if you use [Bindable], the compiler will allow dispatchEvent() in any class; in a black-box manner. -TH --- In flexcoders@yahoogroups.com, valdhor valdhorli...@... wrote: Ooops, my bad.

Re: [flexcoders] Re: dispatchEvent import
Oh, sorry, me wrong... I didn't realize that if you put [Bindable] tag anywhere (not necessarily on class definition), then it will make compiler add extends EventDispatcher... how silly of me
[flexcoders] Re: dispatchEvent import
Hi Marco,
That does look like a problem. The dispatchEvent() method is available
for any UIComponent subclass or any class that extends EventDispatcher.
So, if you're going to use [Bindable] properties in the presentation
model, you would want to have the PM extend EventDispatcher:
import flash.events.EventDispatcher;
public class UserPresentationModel extends EventDispatcher
{
private var _currentState : String;
[Bindable( currentStateChanged )]
public function get currentState() : String
{
return _currentState;
}
public function set currentState( state : String ) : void
{
_currentState = state;
dispatchEvent( new Event( currentStateChanged ) );
}
}
This will allow you to bind the property to a view.
For events that you want to [Mediate], you would use the injected
dispatcher:
[Dispatcher]
public var dispatcher:IEventDispatcher;
dispatcher.dispatchEvent( new Event( myEvent ) );
-TH

My question is how could flex compiler understand the 'dispatchEvent'
method in
line 41 and 65? I haven't seen any explicit import of it.

Re: [flexcoders] Re: dispatchEvent import
If it ever worked that may be because of the patched compiler / preprocessor, and so all dispatchEvent calls were translated to what is marked as [Dispatcher]. Maybe it does the same as [Bindable] on class, or maybe like HaXe using directive. Otherwise - just a confusing piece of code... Well, you know, so far the only reasonable place to put metadata in AS3 was __go_to_definitionHelp, and that you don't have to write... :S
[flexcoders] Re: dispatchEvent import
The example does compile and the binding works; even when you remove the injected dispatcher. Kind of stumped on why this works in a class that doesn't extend EventDispatcher. -TH --- In flexcoders@yahoogroups.com, Oleg Sivokon olegsivo...@... wrote: If it ever worked that may be because of the patched compiler / preprocessor, and so all dispatchEvent calls were translated to what is marked as [Dispatcher].

Re: [flexcoders] Re: dispatchEvent import
Yes, this component is neither UIComponent nor extend EventDispatcher and I don't have to change it to extend EventDispatcher because every things works well. For me it's so strange!!

Re: [flexcoders] Re: dispatchEvent import
OK... dispatchEvent is an undocumented global function... test case: var ns:Namespace = new Namespace(); trace(ns::dispatchEvent); Another hack in AS3... well... I have couple of strong words about this, but these should be only spoken in private... crap :(
