That was probably Kurt Schmucker's book, which described a pre-release of
MacApp 1.0.  The latest version available is 2.0b9, and the class hierarchy
is much richer.  

I suppose some might say richer is marketing-speak for more complicated, but
in general, I don't think this is the case.  MacApp 2.0 greatly simplified
the task of laying out windows, and building custom dialog boxes.  

MacApp 2.0 also provides runtime access to the structure of your program.
For example, you can find out all the subclasses of a given class at
runtime, and you can create an instance of a class given its class name as a
string.  This makes it possible to implement a generalized object I/O
mechanism.  (I've done a simple version of this for an upcoming MacApp
book.)

MPW C++ is a full implementation of C++, with a couple of Macintosh
extensions.
