| enum
| {
|   COLUMN_VALUE,
|   COLUMN_TEXT,
|   N_COLUMNS,
| };
|
| store = gtk_list_store_new (N_COLUMNS,
|                             G_TYPE_INT,
|                             G_TYPE_STRING);
|
| cell = gtk_cell_renderer_progress_new ();
| gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (treeview),
|                                              -1, "progress", cell,
|                                              "value", COLUMN_VALUE,
|                                              "text", COLUMN_TEXT,
|                                              NULL);

Ahh. This was the part I was missing.

| GtkTreeIter iter;
| gtk_list_store_append (store, &iter);
| gtk_list_store_set (store, &iter,
|                     COLUMN_VALUE, 40,
|                     COLUMN_TEXT, "blah", /* see
http://library.gnome.org/devel/gtk/unstable/GtkCellRendererProgress.html#GtkCellRendererProgress--text
*/
|                     -1);
|

And thanks for the reference above!
