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, XtInitializeWid‐
  getClass() 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 function.

  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.
