Maybe the easiest way to do it is to just add more fields when defining
the store, and put the data there. (gtk_list_store_new...)

You don't have to show it when linking the store to the view, so you can
have more fields than those visible. This saves the trouble of setting
the data with ..._set_data() and is easier to retrieve later on.
