good, I've done it.  The checkbutton is in the treeview, I  see it but I
cannot click on  it. I mean, it  doesn't toggle. Here is a  bit of code,
can you please tell me what I'm missing in order to let it behave like a
normal checkbutton?

  swap->store = gtk_tree_store_new (N_COLUMNS,
                                    G_TYPE_BOOLEAN,
                                    G_TYPE_STRING);
  swap->treeview = (GtkTreeView*) gtk_tree_view_new_with_model ((GtkTreeModel*) swap->store);
  gtk_container_add (GTK_CONTAINER(swap), (GtkWidget*) swap->treeview);
  gtk_widget_show ((GtkWidget*) swap->treeview);

  renderer1 = (GtkCellRendererToggle*) gtk_cell_renderer_toggle_new ();

  column1 = gtk_tree_view_column_new_with_attributes ("Usare",
                                                     renderer1,
                                                     "active", USE_COLUMN,
                                                     NULL);
  gtk_tree_view_column_pack_start (column1, GTK_CELL_RENDERER (renderer1), 0);
  gtk_tree_view_insert_column(swap->treeview, column1, 1);
  gtk_widget_show((GtkWidget*) column1);

  renderer2 = (GtkCellRenderer*) gtk_cell_renderer_text_new ();

  column2 = gtk_tree_view_column_new_with_attributes ("Partizione di swap",
                                                     renderer2,
                                                     "text", NAME_COLUMN,
                                                     NULL);
  gtk_tree_view_column_pack_start (column2, GTK_CELL_RENDERER (renderer2), 0);
  gtk_tree_view_insert_column(swap->treeview, column2, 1);
  gtk_widget_show((GtkWidget*) column2);

...

  gtk_tree_store_append (swap->store, &(swap->iter), NULL);

  gtk_tree_store_set (swap->store, &(swap->iter), USE_COLUMN, NULL,
                                                  NAME_COLUMN, "ciao",
                                                  -1);

By the  way, I've  got a pair  of questions.  In the doc  page I  read :
"Object properties  can be  set globally  (with g_object_set())"  . What
does it mean? Do I need it to let the button toggle? In the last line of
the  code I  posted I  pass a  NULL in  the column  where should  be the
checkbutton. Is it correct?

Thank you.
