How to use GtkSheet - Part 4 - set values with justification?


Solution

Important Note: This only works for PHP-GTK2 compliled with the additional library GtkExtra. For linux, you can download the files from http://gtkextra.sourceforge.net/ and do a recompile. For windows, you may use the builds by Elizabeth Smith or the official php-gtk2 beta release available at http://gtk.php.net/download.php. Both contain all the required gtkextra libraries and dll's. In the php.ini, don't forget to add php-gtk.extensions = php_gtk_extra2.dll to turn on GtkExtra.
