I agree 100%.  State machines are the nature of GUIs. 
However it is tedious to design a complete and
detailed state machine for every GUI component in your
app.  I think this is one of the major reasons for so
many bugs in GUI applications.

Your notes made me think of a consistent
reperesentation of state machines in terms of C++
templates. It should be generic enough to be used in
all sorts of things.

And yes, in the basic widget library, the state
machine issues are to be specifically avoided (if
possible).
