You can write your code like that, but what code would set those values? None of the MVC frameworks I know of are running when the preloader is running. That’s the point of the preloader. It is framework independent and very lightweight so you can view something while the rest of the frameworks get downloaded and initialized.
There are two phases to the preloader: download and initialize. You could probably set something in the initializing phase if you really want to.

Public class MyDownloadProgressBar extends SparkDownloadProgressBar { private var _injectedClass:MyInjectClass; private var _preloaderModel:PreloaderModel; public function set injectedClass(value:MyInjectClass):void { this._injectedClass = value; } public function set preloaderModel(value:PreloaderModel):void { this._preloaderModel = value; } } Ideally we would like to have a generic custom preloader component with an MVC structure that uses dependency injection. ________________________________ To: [email protected] From: [email protected] Date: Tue, 9 Aug 2011 10:39:41 -0700 Subject: Re: [flexcoders] Inject dependency into Flex application preloader The preloader is instantiated long before the application. The app’s preloader property isn’t used at runtime, the compiler generates special code for it. A preloader can certainly examine its environment and do different things. There are a few custom preloaders on my blogs.
