248. How to use GtkSheet - Part 3 - set values?

Problem

You have displayed a 2D array in a GtkTable in How to display a 2D array in table - Part 1?.

You have also displayed a 2D array in a GtkTreeView in How to display a 2D array in GtkTreeView - Part 1?.

Now you would like to display the 2D array in a GtkSheet as shown below:

How to use GtkSheet - Part 3 - set values?


Solution

  • Make sure your version of PHP-GTK2 has the GtkExtra library, and the feature turned on in php.ini. (See notes below.)
  • Create the spreadsheet as outlined in How to use GtkSheet - Part 1 - create the spreadsheet?
  • Set the value of a cell with GtkSheet::set_cell_text($row, $col, $value)

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.
