[flexcoders] Re: cairngorm: calling a function in a view

Tue, 07 Nov 2006 16:45:25 -0800

Here’s a quick illustration, hope it is helpful.

 

Command ->

public function result(re:*):void {

            ModelLocatorgetInstance().myviewmodel.myXMLParser( re.result );

}

 

ModelObject ->

[Binadble]

class MyViewModel {

            public function myXMLParser(val:XML):void {

                        // parser logic

                        view_xml = parsedData;

            }

            public var view_xml:*;

}

 

View ->

<view:MyComponent dataProvider="{model.myviewmodel.view_xml}" />

I'm sorry, I think you might have just broke my brain :( Or maybe my
grasp on Cairngorm isn't quite as strong as I thought it. The root of
my understanding is based on Jesse (JesterXL)'s example with quite a
few modifications.

I built the parse() method inside the component as it would get into
nested arrays and storing a lot of variables in the global program
that don't have value to do it the other way. Plus, from an OO
perspective I think that is more sound, I can give the SWC to another
developer along with sample XML format to provide to it. Make sense no?

Part of this may be the 'many ways to skin a cat' challenge that
Cairngorm is more a frame on which to hang your code rather than
something that forces you to program in a particular manner.

Any samples of methods on the model and calling components / their
getters / setters from views would be valuable.

Thx,
Jamie
