- A slew of patches
- A couple of documentation updates
- A PHP-GTK 2 talk is scheduled for php|works

Read on for details of the PHP-GTK news for June 14th through the 21st.
Development
GtkTreeModel Delete Row Crash:
The previously reported crash that occurs when trying to delete GtkTreeModel rows while in a foreach() callback, will not be fixed. This is because it is a known issue with Gtk+. During the callbacks called by some methods, such as foreach(), you may not delete rows of a model. Doing so causes a double free memory corruption.
To get around this, you can create an array of iters for the rows that are to be deleted during the foreach call and then delete them later.
Memory Leak Fixed:
The previously reported memory leak (bug #37787) which occured when Gtk::timeout_add() was used within a class, has been fixed. It is now safe to use Gtk::timeout_add() anywhere.

General
PHP|Works:
Andrei has been selected to give a talk at PHP|Works in Toronto this September. His talk, simply titled “PHP-GTK 2″ will take place on the last day of the conference. Anyone interested in learning about PHP-GTK 2 from the creator himself, should definitely try to attend.
IRC
GxLib 2D Graphics Package:
Marc Quinton from the PHP-GTK IRC channel (#php-gtk on freenode) has created a 2d graphics package, called GxLib, for PHP-GTK 2. The package allows for transformations of lines and simple shapes. It is a very interesting example of what can be done with PHP-GTK 2.
