Christopher A. Rath (car@melmac.att.com) was so kind as to provide the
correct answer to the problem which I will give here for anyone else
who is as puzzled as I.

>>In order for the Xw row column widget to notice that a toggle has

>>well as setting XtNset to True.
>>i.e.

>>XtSetArg(args[n], XtNset, (XtArgVal)True)       n++;
>>XtSetValues(toggle, args, n);
>>XtCallCallbacks(toggle, XtNselect, (caddr_t)0);


Works like a charm!
