RE: [wxperl-users] Re: wxValidator available via wxPerl

[James L. <ja...@mi...>]

Mattia,
Thanks, as usual, for the to-the-point and quick support!

If/when I manage to produce a useful validator, I would be more than
happy to submit it.  Currently I'm still getting my head round how
everything fits together!

James
