If you just want to update the list selections, then why don't you try setting
the resources.  I have used this to update a list in extended selection mode,
because figuring out what has been updated seems too complex.  I used this code
in a callback routine which copies the selected items from one list to another:


void Copy2_rt_list (w, client_data, call_data)
   Widget     w;
   caddr_t    *client_data;
   XmListCallbackStruct *call_data;
{
  int n;
  Arg args[10];
  n = 0;
  XtSetArg (args[n], XmNitemCount, call_data->selected_item_count); n++;
  XtSetArg (args[n], XmNitems, call_data->selected_items); n++;
  XtSetValues (rt_list, args, n);
}
