Extending Loader

Question

I´m trying to extend the Loader class.

I want to store a variable on it.

Example:

package
{
import flash.display.Loader;

public class MyLoader extends Loader
{
    private var _typeOfGallery:String

    public function MyLoader()
    {
        super()
    }

    public function set typeOfGallery(value:String):void
    {
        _typeOfGallery = value
    }

    public function get typeOfGallery():String
    {
        return _typeOfGallery
    }
}

}

Then I´m using like this:

var loader:MyLoader = new MyLoader()
loader.typeOfGallery = 'games'
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded)

function loaded(e:Event):void{
trace(e.target.typeOfGallery)
}

I´m receiving this error:

ReferenceError: Error #1069: Property typeOfGallery not found in flash.display.LoaderInfo and has no pattern value.

(I have translated from portuguese to english the error message)

How could I extend Loader so I don´t receive this error?

Thanks.

Answer 1

Loader does not dispatch the Event.COMPLETE event. You should listen to

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded)

and then get your MyLoader with

function loaded(e:Event):void{
   trace(((e.currentTarget as LoaderInfo).loader as MyLoader).typeOfGallery);
}

In your code, e.target is a LoaderInfo because the COMPLETE event bubbles to the Loader itself.

Answer 2

loader.contentLoaderInfo.typeOfGallery = 'games'

IS WRONG - you want to go for the loader not for its contentLoaderInfo...

loader.typeOfGallery = 'games'

trace(e.target.typeOfGallery) should work cause its a reference to the loader!!
