  21  A validator has up to three purposes:
  22
  23  1) To validate the data in the window that's associated
  24     with the validator.
  25  2) To transfer data to and from the window.
  26  3) To filter input, using its role as a wxEvtHandler
  27     to intercept e.g. OnChar.
  28
  29  Note that wxValidator and derived classes use reference counting.
