Yes, and no; you can use Wx::PlValidator and derive
your own valiadtors, but the standard
Wx::TextValidator and Wx::GenericValidator are not wrapped,
because at the time I has quite a lot other more important classes to wrap ( it was 
before wxPerl 0.01 ), and then just forgot about it.

By the way, I think that wxGenericValidator and wxTextValidator are
quite limited, and their functionalities can be implemented
in Perl ( using Wx::PlValidator ), probably with a better interface.

To derive a new validator:

package MyValidator;

use vars qw(@ISA); @ISA = qw(Wx::PlValidator);

sub new {
	my $class = shift;
	my $this = $class->SUPER::new();

    ...

    return $this;
}

# see the docs for the three following functions
sub TransferFromWindow { ... }
sub TransferToWindow { ... }
sub Validate { ... }

1;

Of course no one stops you from contributing your validators
back to wxPerl, if you feel like it...
