# Stage.addListener()

#### Availability

Flash Player 6.

#### Usage

    Stage.addListener(myListener)

#### Parameters

`myListener` An object that listens for a callback notification from the `Stage.onResize` event.

#### Returns

Nothing.

#### Description

Method; detects when a Flash movie is resized if `Stage.scaleMode = "noScale"`. The `addListener` method doesn't work with the default movie scaling setting (`"showAll"`) or other scaling settings (`"exactFit"` and `"noBorder"`).

To use `addListener`, you must first create a listener object. A listener object is an object that receives notification from an event when that event is triggered in a movie. Listener objects of the Stage object receive notification from `Stage.onResize`.

#### Example

This example creates a new listener object called `myListener`. It then uses `myListener` to call `onResize` and define a function that will be called when `onResize` is triggered. Finally, the code adds the `myListener` object to the callback list of the Stage object. Listener objects allow multiple objects to listen for resize notifications.

    myListener = new Object();
    myListener.onResize = function () { ... }
    Stage.addListener(myListener);
