I've been meaning to put together some simpler examples, but haven't
had the time of late. Perhaps I should make some...
There are currently issues running a full-screen graphics context
whilst in a wxMax event loop. I've yet to find out why there's no
events being carried up to it yet. (something low-level, probably).
Windowed is fine.
wxMax is perfect for your everyday apps though.
The book you mention is great, and although it is C++ based, it
translates well to wxMax as I've tried to mirror the API as closely as
possible. That's also what's made converting the samples (from C++)
easier, as it's almost a copy/paste/tweak process.
You might also be interested in wxCodeGen (see the tools folder),
which will generate code from wxFormBuilder project files. That might
help you understand how some of the event stuff hangs together (by
comparing what you made in the GUI editor, with the code that was
generated).
