XtInitializeWidgetClass - initialize a widget class

object_class
                 Specifies the object class to initialize.

       If the specified widget class is already initialized, XtInitializeWidgetClass returns immediately.

       If  the class initialization procedure registers type converters, these type converters are not available
       until the first object of the class or subclass is created or XtInitializeWidgetClass is called.
