The PV-WAVE system function WtInit initializes the Widget Toolbox. You must execute WwInit before any other Widget Toolbox functions. WtInit does the following:

For example:

top = WtInit(name,class)

The name parameter specifies the name of the application, and the class parameter indicates a more general category of application class. For example, in the example program at the end of this chapter, the call to WtInit is:

war(0)= WtInit('example', 'Examples')

where example is the name of the application, and Examples specifies a general class to which example belongs. One purpose of the general class (Examples) is that resources in a single resource file can be shared among elements of that class.

See the example Widget Toolbox application at the end of this chapter.
