9.2.1 The Application Frame Protocol

application-frame [Protocol Class]	

Summary: The protocol class that corresponds to an application frame. If you want to create a new class that behaves like an application frame, it should be a subclass of application-frame. Subclasses of application-frame must obey the application frame protocol.

All application frame classes are mutable.

application-frame-p [Function]	

Arguments: object

Summary: Returns t if object is an application frame; otherwise, it returns nil .
