Sample Code 251: How to use GtkSheet - Part 6 - non editable browser mode?

Written by kksou

Problem

You have displayed a 2D array in a GtkSheet in How to use GtkSheet - Part 3 - set values?.

Instead of allowing the user to change the cell contents, you would like to set up the GtkSheet in browser mode so that the cell contents are non-editable (similar to a standard GtkTreeView) as shown below:

How to use GtkSheet - Part 6 - non editable browser mode?

Solution

Make sure your version of PHP-GTK2 has the GtkExtra library, and the feature turned on in php.ini. (See notes below.)
Instead of using the standard constructor to create GtkSheet, use GtkSheet::new_browser() instead.
Once the GtkSheet is created, use it like a standard GtkSheet.

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.
