Re: Connection methods

The one just about everyone uses is $window->connect_object('destroy', array('gtk', 'main_quit')); It'd be confusing (and pointless) if you also passed $window, and it'd get needlessly complicated if you just used a straight connect() call. You'd also use it anywhere you didn't want to pass the initial object but wanted to use one of its signals, and that does arise a fair deal. Sometimes you'll need the signal's parameters to be passed too, sometimes you won't. In event signals it's fairly common to want to do something with $event as well as with your user data (ie other widgets etc), but at present we don't have a way of passing $event without passing the initial object. ----- Original Message ----- From: "Andrei Zmievski" <andrei@gravitonic.com> To: "Steph" <steph@zend.com> Cc: "PHP DEV" <php-gtk-dev@lists.php.net>; "Scott Mattocks" <scott@crisscott.com> Sent: Friday, October 14, 2005 9:40 PM Subject: Re: [PHP-GTK-DEV] Connection methods > Can you please an example of this? > > -Andrei > > On Oct 14, 2005, at 12:37 PM, Steph wrote: > > > Yes, because if you want to do something with an object that isn't > > responsible for emitting the signal, it makes the code much more > > readable if > > you use connect_object() or something equivalent.
