Accessing the stage from a class

[Cortana]

Dudes!

I want to be able to dynamically add and remove an event listener for the keyboard to the stage from a class but Im not sure how to do it. I've used code like this :

package
{
	import flash.events.*
	import flash.display.*
	public class Main {
		public function test() : void
		{
			stage.addEventListener (KeyboardEvent.KEY_DOWN, keyPressed);
			function keyPressed (event : KeyboardEvent) : void {
				trace("hello?")
			}
		}
	}
}

But when I come to compile it says stage is not defined. Does anyone know how I can access the stage from a class function or cant it be done?

You can add a reference of a display object in display list to your class, usually come with the constructor function.

the stage property is only accessible to display objects. This property is also null until the object has been added to an active (visible) display list. Note: the only display object that has access to the stage in its constructor is the document class instance. For more information, see:

Hi

georgecalgary's answer was enough to help me. Taking my posted code as an example, I simply changed this line

public function test() : void

to

public function test(stageisplayObject) : void

and callled it like this :

var tester:Main = new Main()
tester.test(stage)
