 * DESCRIPTION:
 *      This module is part of the OPPS editor, xopps.  It contains
 *      object routines to handle chdate objects.
 *
 *                              CHANGE HISTORY
 *
 * $Log: chdate.c,v $
 * Revision 1.23  1994/08/10 22:02:18  cassie
 * fixed DialogFlagSet calls
 *
 * Revision 1.22  1994/07/20  19:06:35  clm
 * updated TRUE, ERROR etc in cancel & ok_button functions
 * to DIALOG_ constants
 *
 * Revision 1.21  1994/06/16  21:55:48  clm

 *
 * Revision 1.13  1992/12/15  16:41:34  clm
 * fixed memory leak in Color widget
 *
 * Revision 1.12  1992/12/10  21:45:40  clm
 * fixed new_index so chart is always object 0
 *
 * Revision 1.11  1992/10/02  19:49:18  clm
 * housekeeping
 *
 * Revision 1.10  1992/09/17  15:24:24  clm
 * added display options to object
 *
 * Revision 1.9  1992/09/16  14:55:03  clm
 * fixed load function so doesn't add object if error in load
 *
 * Revision 1.8  1992/09/14  18:33:36  clm
 * added layer to object
 *
 * Revision 1.7  1992/08/31  23:03:24  clm
 * added color to chart date object
 *
 * Revision 1.6  1992/08/20  18:05:54  clm
 * fixed load error checking for font
 *
 * Revision 1.5  1992/08/20  15:16:49  clm
