I got this reply from Cameron Laird and thought it would be worth
passing on. Thanks to all for their input on this and the other question.

Yes.
You can use PMW; an example would be
Pmw.EntryField(validate = {'max': 13})
Alternatively, you can write you own validatecommand for the Entry.
Also, it might interest you that an Entry *can* be multi-line, with
built-in wrapping.
