Global Var inside Constructor to pass to view

[eluser]maicobreako[/eluser]
I was having trouble getting MY_Controller to work and ran across this thread.
My question is why does parent::__construct(); work? The only referrence to this I've seen, is this thread.

I couldn't get parent::MY_Controller(); to work in the Contact controller, I'd get this message:

"Fatal error: Call to undefined method MY_Controller::MY_Controller() in C:\wamp\winf\contact\controllers\contact.php on line 8"

BTW, using ci svn version from a few weeks ago.

/winf/contact/libraries/MY_Contoller.php

Code:

class MY_Controller extends Controller
{
    function __construct()
    {
        parent::Controller();
        <<snipped>>
    }
}

/winf/contact/controllers/contact.php

Code:

class Contact extends MY_Controller
{
    function __construct()
    {
        parent::__construct();
        $this->load->helper(array('url', 'form', 'html'));
        $this->load->library(array('form_validation', 'session'));
        $this->form_validation->set_error_delimiters('<div class="error">', '</div>');
    }
