+Indeed, in the the 'liststore-col-w-double-renderers-pixbufs.rb' example in section [8.2.4], we use the Gdk::Pixbuf rather than the String data type to define our model (store). However note, that in both examples here, and in the section [8.2.4] the renderers are defined to be of type Gtk::CellRendererPixbuf:
+
+ renderer = Gtk::CellRendererPixbuf.new
+
+The difference is in definition of the attributes which are assigned image data in their respective columns. Here we use :stock_id, whereas in the example in [8.4.2] we use the :pixbuf attribute:
+
+ column.add_attribute(renderer, 'stock_id', $img_column)
+
+and in the example program in section [8.4.2] ((<(Multi-item Super Columns)|tut-gtk2-treev-trees#Multi-item Super Columns>)):
+
+ column.set_attributes(pixb_renderer, :pixbuf => ICON)
+
+The add_attribute and set_attributes accomplish the same thing. If this is news to you, I suggest you reread the above mentioned section [8.4.2].
