Re: cannot create gtksourcestylesheme interface

I thought I fixed this in this check-in: http://cvs.php.net/viewvc.cgi/php-gtk/main/phpg_support.c?revision=1.17&view=markup Can you try rebuilding from PHP-GTK CVS again? -Andrei On Apr 19, 2007, at 8:17 AM, Jake Cobb wrote:

Hello, I'm running into the same problem. I have a GtkTreeView that I was using a GtkListStore model with. However, for quick searching in the list I wrapped the GtkListStore in a GtkTreeModelFilter. The problem, of course, is that GtkTreeModelFilter implements GtkTreeModel but not GtkTreeSortable, effectively hiding the sorting capability of the GtkListStore. So I tried a simple class to tie them together and pass the sortable methods through to the underlying model. ---------- <?php class LyrGtkTreeModelFilterSortable extends GtkTreeModelFilter implements GtkTreeSortable { public function get_sort_column_id() { return $this->get_model()-get_sort_column_id(); } public function has_default_sort_func() { return $this->get_model()->has_default_sort_func(); } public function set_default_sort_func($callback) { $this-get_model()->set_default_sort_func($callback); } public function set_sort_column_id($column_id,$order) { $this-get_model()->set_sort_column_id($column_id,$order); } public function set_sort_func($column,$callback) { $this-get_model()->set_sort_func($column, $callback); } public function sort_column_changed() { $this->get_model()-sort_column_changed(); } } ?> ---------- This dies with the same error mentioned by Christian. ---------- Fatal error: Cannot inherit previously-inherited constant gtype from interface GtkTreeSortable ---------- Although it says fixed in 5.1, the main PHP bug list had a very similar issue: http://bugs.php.net/bug.php?id=33732 My build is PHP 5.2 and PHP-GTK from CVS, checked out roughly a month ago. Thanks. -Jake Cobb * *>Christian, you find the best (obscure) bugs. This one was rather non- trivial. I committed a fix, but I do need you and others to test areas in PHP-GTK related to interfaces, including tree models. Also, >test GdkGC stuff (creating and getting them). If you're curious about what the problem was.. readon. When get_style_scheme() is called, it dynamically creates a class called >GtkSourceDefaultStyleScheme that implements the GtkSourceStyleScheme >interface. Since both the class and the interface had 'gtype' >constant registered, there was a conflict. So now, we don't register >'gtype' for interfaces. However, that uncovered another problem.

This necessitated changing how we register interface methods and also required unsetting the abstract flag on inherited >methods and class itself. So that's why I'm asking for more testing >in these areas. -Andrei On Feb 3, 2007, at 6:46 AM, Christian Weiske wrote:

Hi all, trying this: <?php $gslm = new GtkSourceLanguagesManager(); $gsl = $gslm->get_language_from_mime_type('application/x-php'); $schema = $gsl->get_style_scheme(); ?> I get -------------- Fatal error: Cannot inherit previously-inherited constant gtype
