ASTRA AlertManager
AlertManager is a UI component that creates and manages the queuing of alert windows in a Flash Application.
Getting Started: AlertManager for Flash CS3
Using AlertManager in your Flash application is simple and requires just a few lines of ActionScript.
Initializing a AlertManager with ActionScript
To include an Alert in your application, you must first add the AlertManager component to your library. You can do so by dragging it from the Components panel directly to the library, or by dragging an instance to the stage, and immediately removing it (it will stay in your library). Additionally, you need to import the following class for use in your class or frame script.
The class com.yahoo.astra.fl.managers.AlertManager is the main required class for an AlertManager control.
To create an Alert, you call the AlertManager.createAlert() method. This is a static method, so you actually call it on the AlertManager class (hence the uppercase "AlertManager"). This method has 2 required parameters and six optional parameters used for customization.

To see a live example, please install Adobe Flash Player version 9 or higher.
