Applications cannot call Workplace Shell objects' methods directly. They are not clients of Workplace Shell objects, in the same sense that applications can be clients of SOM objects. Workplace Shell objects are derived from the WPObject class, which, in turn, is derived from the SOMObject class. They share all the features of SOM objects but only the Workplace Shell can directly manipulate them. Because there are times when applications might need to effect changes to the Desktop and objects on the Desktop, the Workplace Shell provides functions that permit you to proceed these changes. This chapter describes the Workplace Shell Win Functions.
