45 * The XtArgCollector class is simply a dynamic array of Args.
46 * It is useful to build an ArgList to pass as an argument to
47 * XtSetValues. This is a way to collect resources and values
48 * over several functions and then finally set them at another
49 * point. This can help prevent multiple redisplays in widgets
50 * like XmList which don't have a DisableRedisplay convenience
51 * function like XmText. It's a class for setting resources
52 * similar to the following:
54 * XtSetArg (args[n], XmNmarginHeight, 5); n++
55 * XtSetValues (widget, args, n);
