* Gtk::CellRendererToggle displays a boolean value in form of a check box or as a radio button.
* Gtk::CellEditable is a special cell that implements editable cells (ie. Gtk::Entry or Gtk::SpinButton in a treeview)
-We said that model and view have to be connected (i.e. Gtk::TreeView has to be associated with Gtk::TreeStore or Gtk::ListStore). How the tree data types (strings, numbers and boolean) are handled in Gtk for this eventuality is best seen in the code which indirectly points out to the Gtk::CellRendererText's ability to separate the forementioned data types. Following is the example code (note that a renderer is not even shown here, though if it is to render certain column from model, it has to be made aware of that column with the pertinent data type):
