OS/2 Version 2.0 introduces a new choice for application developers: whether to develop their applications using traditional PM programming techniques or to use the System Object Model (SOM) interfaces and the Workplace Shell class hierarchy to develop fully-integrated applications.
This chapter provides an overview of the two programming models, and discusses the extent to which it is possible to integrate a PM program into the Workplace Shell environment.
For more detailed information on programming for Presentation Manager and for the Workplace Shell, see OS/2 Version 2.0 - Volume 4: Application Development.
