A validator has up to three purposes:
1) To validate the data in the window that's associated
with the validator.
2) To transfer data to and from the window.
3) To filter input, using its role as a wxEvtHandler
to intercept e.g. OnChar.
Note that wxValidator and derived classes use reference counting.
