As with the editable text renderers, you have to manually apply the changes performed by the user. Otherwise, the button will not toggle visually on the screen. Because of this, Gtk::CellRendererToggle provides the ((*toggle*)) signal, which is emitted when the user presses the check button.
-We are using the same program as in the introductory session to the tree store (1.3 ((<Using Gtk::ListStore|tut-gtk2-treev-parts#Using Gtk::ListStore>))), there called "treestore.rb". The only changes are in the ((*setup_tree_view(treeview)*)) method, where we had to change the type of our cell renderer. An important, often overlooked change is also in the column line, where we change the name of the attribute that used to be "text" to "active". Since we wish to provide our users with the ability to interactively change the status of "Buy" column, wee need to make our toggle button clickable, which means that we also need to provide the callback proc (block) which will set the toggle to the new value.
