Sorry again! Just after writing the question I'v sold!
It is very, very easy (I'm really unpatient)!
$myCtrlText = Wx::TextCtrl->new( $frame, -1, "some value", [10, 10], [ 100, 20
], 0 );
$myCtrlText->{DATA} = 'test data';
EVT_CHAR( $myCtrlText, \&Onkeydown );
sub Onkeydown {
my ( $this, $event ) = @_;
my $key = $event->GetKeyCode();
print $this->{DATA};
}
