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 widgets.  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 CDK-
		 FUNCS for each widget.

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

AVAILABLE FUNCTIONS
       The functions declared in <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".
