abstract class

The InteractiveObject class is a core class in Flash player. InteractiveObject is an abstract base class so you cannot create instances of it. Also, you cannot subclass it yourself because it is not a complete class. InteractiveObject is a subclass of DisplayObject and adds support for interacting with the user of the Flash application. Flash classes which are not subclasses of InteractiveObject, such as Shape and StaticText, do not respond to mouse or keyboard actions.
