How do I reference WindowedApplication from inside a class I made?

I'm using Flex 4.5, and I have imported a custom class I wrote into the main MXML file.

Inside the class file, I want to be able to create a TitleWindow using the PopUpManager like this:

package classes {
    import components.*; // My custom components
    import mx.managers.PopUpManager;

    public class SomeClass {
        public function showPopUp():void {
            PopUpManager.createPopUp(this,NewProjectPrompt,true);
        }
    }
}

NewProjectPrompt is a custom component I made. The compiler is giving me the following error:

1067: Implicit coercion of a value of type classes:Project to an unrelated type flash.display:DisplayObject.

This is because this isn't pointing at WindowedApplication. How do I make the first parameter in .createPopUp() point to the WindowedApplication?

If your WindowedApplication file is named "MyApp.mxml" then you would write a reference from a component to it like this:

MyApp(this.parentApplication)

This will return the actual WindowedApplication and you can call its public methods or stick it in a variable if need be.

this code works!

public function showPopUp(){
PopUpManager.createPopUp(FlexGlobals.topLevelApplication as DisplayObject,NewProjectPrompt,true); }
