Re: Viewport critical warnings - sorted

The viewport warnings weren't a PHP-GTK issue, they were caused by a packing issue. As far as I remember. Anyway here's the tidiest and most up to date version hot from my desktop. Beware, we don't use the same CS - maybe we should decide on a set at some point? I notice Jeremy has a third way... I have a way to switch off source highlighting in my version - initially because it was 'under development' and now because it makes the framework visibly slower to load here since it was fixed, probably because parsing the token list via PHP takes a while? YMMV on other boxen... I have to say it looks pretty when it's enabled though. - Steph ----- Original Message ----- From: "Steph Fox" <steph@zend.com> To: "Christian Weiske" <cweiske@cweiske.de>; "PHP-GTK Dev list" <php-gtk-dev@lists.php.net> Sent: Saturday, October 22, 2005 1:28 PM Subject: Re: [PHP-GTK-DEV] Viewport critical warnings > I fixed this in my own version, can't remember how.
