XtInitializeWidgetClass()												 XtInitializeWidgetClass()

Name
  XtInitializeWidgetClass - initialize a widget class without creating any widgets.

Synopsis
  void XtInitializeWidgetClass(object_class)
	   WidgetClass object_class;

Inputs
  object_class
	      Specifies the object class to initialize; may be of class objectClass or any subclass thereof.

Availability
  Release 4 and later.

Description
  XtInitializeWidgetClass() initializes a widget class in the same way that XtCreateWidget does, but without creating any widgets.  It checks
  the class_inited field of the specified class and all its superclasses, in superclass-to-subclass order, and if that field is False for any
  class,  it  calls  the  class_initialize()  and  class_part_initialize()  methods  for the class and all of its superclasses.  Finally, the
  class_inited field of the specified class is set to nonzero.

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

Usage
  A widget class is automatically initialized when the first instance of a widget is created; few applications will need to  use  this	func-
  tion.

  If  a class initialization procedure registers type converters, those type converters are not available until the first object of the class
  or subclass is created or until XtInitializeWidgetClass() is called.	This function was added in Release 4 so that the XtVaTypedArg feature
  of XtVaCreateWidget() can be used to convert a resource value while creating the first instance of a particular widget class.
