XmDataFieldSetString — A DataField function that sets the
string value

     #include <Xm/DataF.h>
void XmDataFieldSetString(
Widget widget,
char * value);

     XmDataFieldSetString sets the string value of the
DataField widget.  This routine calls the widget’s
XmNvalueChangedCallback and verification callbacks, either
XmNmodifyVerifyCallback or XmNmodifyVerifyCallbackWcs, or
both. If both verification callback lists are registered,
the procedures of the XmNmodifyVerifyCallback list are
executed first and the resulting data is passed to the
XmNmodifyVerifyCallbackWcs callbacks.  It also sets the
insertion cursor position to the beginning of the string and
calls the widget’s XmNmotionVerifyCallback callbacks.

widget    Specifies the DataField widget ID

value     Specifies the character pointer to the string
          value and places the string into the text edit
