Call Function Within Class Using Gtk::timeout_add();

Di, 12/06/2007 - 13:30 — Christopher Stevens

Hello,
Calling a function on a repetitive basis is simple enough using something like:
Gtk::timeout_add(200, 'subtract'); //call subtract() 5 times per second

However, how would I call subtract() if it is within a class? Example:

<?php
class CoolClass {
    private $clickInt = 0;
   
    function subtract() {
        $this->clickInt--;
                return true;
    }
}

/* //I don't want to call the class function like this, or do I need to?
function subtract() {
    global $coolClassInstance;
    $coolClassInstance->subtract();
    return true;
}
*/

$coolClassInstance = new CoolClass();

$timeoutID = Gtk::timeout_add(200, 'subtract'); //how to call $coolClassInstance->subtract()?

Gtk::main();
?>

Thanks much for the help :)

with an array

You use an array to pass the reference of the class, and the name of the method to call. PHP-GTK takes care of the rest.

<?php
$timeoutID = Gtk::timeout_add(200, array($coolClassInstance, 'subtract'));
?>

Thank you much for the clarification. It works great! Also thank you "Fosfor" and you on the #php-gtk irc chat channel for initial discussion on this topic.
