I have McCormack's book. It is not suitable for learning the Athena widget
sets because everything is very dense.  However, if you have a little idea
of how things are organized under Xaw, this book serve as a excellent
reference when you are actually writing codes.

Unlike Motif (not sure about Xw), Xaw doesn't bundle everything under a 
single gigantic header. A typical Xaw based program contains the standard
Xt headers:

#include <X11/Intrinsic.h>
#include <X11/StringDefs.h>

followed by the headers of the Xaw widgets you actually used. For example,
suppose you want to use the Xaw label widget, then you include the header:

#include <X11/Xaw/Label.h>

Yes, but you should learn Xaw from other books instead. Borrow Vol. 4 
(X Toolkit Intrinsics Programming Manual) of the X-window series by
O'Reiley & Associates, Inc. from library, read the first few chapters
to get an overall idea. Return it and use McCormack's book to start
actual programing.

Hopefully this helps....
