Workplace Shell Implementation

This chapter looks at what happens "under the covers" of the Workplace Shell (WPS). We examine the shell from several viewpoints:

  • The implementation of the WPS as an OS/2 program
  • The different types of shell objects
  • The relationship of the shell to the file system
  • Persistence in WPS objects.

    This chapter will help you to understand how the Workplace Shell is implemented, know what kinds of objects it stores and where it stores information about them. If you wish to understand the System Object Model, object-oriented programming in OS/2 V2.0 and how to create your own WPS program you should read the appropriate sections of the companion volume, OS/2 Version 2.0 - Volume 4: Application Development.
