DESCRIPTION
       Cdk  is	written	in ANSI	C, which has "no" object support.  Most	of the
       object support in Cdk is	done using macros and a	small number of	 types
       which hold object information:

	    CDKFUNCS
		 contains the function pointers	for common methods of the wid-
		 gets.	It is separate from CDKOBJS  because  it  is  compiled
		 into  each  widget's  C code (see the DeclareCDKObjects() and
		 DeclareSetXXchar() macros.  The widget	instances point	 to  a
		 single	copy of	CDKFUNCS for each widget.

	    CDKOBJS
		 Holds	data common to all objects (widget instances).	It ap-
		 pears first in	each widget's  struct  to  allow  Cdk  to  use
		 generic functions in binding.c, cdkscreen.c, position.c, etc.

AVAILABLE FUNCTIONS
       The functions declared in <cdk/cdk_objs.h> are used in situations where
       the expressions are too complex for a macro.

       cleanCdkTitle
	    Remove storage for the widget's title.

       drawCdkTitle,
	    Draw the widget's title.

       positionCDKObject
	    This allows	the user to use	the cursor keys	to adjust the position
	    of the widget.

       setCDKObjectBackgroundColor
	    Set	the background color of	the widget.

       setCDKObjectPostProcess
	    Set	data for postprocessing.

       setCDKObjectPreProcess
	    Set	data for preprocessing.

       setCdkExitType
	    Set	 the  object's	exit-type  based  on the input.	 The .exitType
	    field should have been part	of the CDKOBJS struct, but it is  used
	    too	pervasively in Cdk4 applications to move.

       setCdkTitle
	    Set	the widget's title.

       validCDKObject
	    Returns true if a "new" was	done on	the object but no "destroy".
