/*
 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.
