package Wx::Perl::TextValidator;
=head1 NAME
Wx::Perl::TextValidator - Perl replacement for wxTextValidator
=head1 SYNOPSIS
my $storage = '';
my $validator1 = Wx::Perl::TextValidator->new( '\d', \$storage );
my $validator2 = Wx::Perl::TextValidator->new( '[abcdef]' );
my $validator3 = Wx::Perl::TextValidator->new( qr/[a-zA-Z]/ );
my $textctrl = Wx::TextCtrl->new( $parent, -1, "", $pos, $size, $style,
$validator1 );
=head1 DESCRIPTION
A C<Wx::Validator> subclass that allows filtering user input to
a C<Wx::TextCtrl>.
=head1 METHODS
my $validator1 = Wx::Perl::TextValidator->new( $regexp, \$storage );
my $validator2 = Wx::Perl::TextValidator->new( $regexp );
Constructs a new C<Wx::Perl::Validator>. The first argument must be
a regular expression matching a single-character string and is used
to validate the field contents and user input. The second argument,
if present, is used in TransferDataToWindow/TransferDataToWindow as
the source/destination for the fields contents.
The first argument can be a string as well as a reqular expression
object created using C<qr//>.
