The Application Kit

Abstract

The Foundation Framework is quite low-level and general purpose, defining classes that any program can use, from server programs with little or no interface to user applications with highly graphical interfaces. For the latter type of program, the OpenStep specification also offers the Application Kit, a rich, sophisticated framework of object classes that implement nearly all of the common functionality of event handling, display management, and standard panels and controls, into which you graft your custom objects for application-specific behavior. Additional Application Kit classes provide such amenities as spell checking, data linking between documents, and offering of application functionality to other applications.
