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.

But in essence, going back to your example, there is no capacity to inject
'MyInjectClass' with a public setter?
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.

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.

Is it possible to do something like this hypothetical example:
(application.preloader as CustomPreloader).preloaderModel = new
PreloaderModel();
Or pass in properties, similar to how it's done with item renderers and
'ClassFactory' properties?

Can you provide an example of this, Alex?

You can inject certain kinds of dependencies as long as they don’t drag in
UIComponent.
