RE: [flexcoders] Implicit change events for [Bindable] properties? and some notes on ModelLocator
Yeah, I think this is something that could eventually go into the tool.

Hi Matt,
yeah... more clarity, but at the expense of quite some boiler-plate
code.
I really believe you should consider adding support for this
requirement at the generator level, something like
[BindableWithAutoEvent("myPropChanged")]
public var myProp:String;
this way I would still be expressing the intent, but avoiding the
overhead.
otherwise, integrate it into zorn... ( a la java's "Source > Generate
Getters and Setters..." ).
for now, I use a handy app that generates the code for me:

RE: [flexcoders] Implicit change events for [Bindable] properties? and some notes on ModelLocator
Yes binding will generate the "objectChange" when it's done
automatically, but you'd need to look at the details to figure out if
it's the right property for you. Generally if you find yourself wanting
to handle the event it's a good idea to do the re-write yourself because
I think it's clearer what you intend to accomplish rather than relying
on code-gen.

Subject: [flexcoders] Implicit change events for [Bindable] properties?
and some notes on ModelLocator
Hi all,
I USUALLY FIND MYSELF REWRITING THE FOLLOWING STATEMENT
[Bindable]
public var selectedItem:ItemVO;
TO SOMETHING LIKE THIS
private var __selectedItem:ItemVO;
[Bindable("selectedItemChanged")]
public function get selectedItem():ItemVO{
return __selectedItem;
}
public function set selectedItem( v:ItemVO ):void{
__selectedItem = v;
dispatchEvent( new Event("selectedItemChanged") );
}
// I ommited the Event metadata of course
SO I CAN DO THIS...
is there an implicit event that is fired when a Bindable property is
changed??
I have digged a little into the generated AS and apparently the
"objectChange" event is used in general... but Is there a more
granular approach?
As a tangent to this issue.. ( now this is just in case any cairngorm
fella is reading this ), I believe that the ModelLocator should be
wrapp'able as an MXML tag to support inline event handlers... I always
do that with my model locators ( I just call them models though ).
Of course the MXML wrapper would create a new instance, which itself
would be wrapping a singleton. there are some patterns around that (
all of which involve some unwanted boiler plate code and repetition ).
I will post some more on this later perhaps. need some sleep now. good
night ;)
Best,
Aldo
