I confirm that int( QOrientations() ) returns 0.  Assuming that is
consistent/deliberate and not random (which I imagine it is) I guess that
is what I will use here.

I am still a little troubled by the fact that I can convert enum to int via
int(QOrientations(enum_value)) but have trouble converting int to enum via
QOrientations(int_value).  However the latter does seem to be a PyCharm IDE
warning ("Unexpected type 'int', expected 'Orientations', 'Orientation'")
but works at run-time, so I guess it's OK even if I cannot find a formula
which works without warning.  It would be nice to see a PyQt expert
statement on what is the correct way to handle this not-unusual
requirement....
