+ * SECTION:gtkliststore
+ * @Short_description: A list-like data structure that can be used with the GtkTreeView
+ * @Title: GtkListStore
+ * @See_also:#GtkTreeModel, #GtkTreeStore
+ *
+ * The #GtkListStore object is a list model for use with a #GtkTreeView
+ * widget. It implements the #GtkTreeModel interface, and consequentialy,
+ * can use all of the methods available there. It also implements the
+ * #GtkTreeSortable interface so it can be sorted by the view.
+ * Finally, it also implements the tree <link linkend="gtktreednd">drag and
+ * drop</link> interfaces.
+ *
+ * The #GtkListStore can accept most GObject types as a column type, though
+ * it can't accept all custom types. Internally, it will keep a copy of
+ * data passed in (such as a string or a boxed pointer). Columns that
+ * accept #GObject<!-- -->s are handled a little differently. The
+ * #GtkListStore will keep a reference to the object instead of copying the
+ * value. As a result, if the object is modified, it is up to the
+ * application writer to call gtk_tree_model_row_changed() to emit the
+ * #GtkTreeModel::row_changed signal. This most commonly affects lists with
+ * #GdkPixbuf<!-- -->s stored.
+ *
+ * <example>
+ * <title>Creating a simple list store.</title>
+ * <programlisting>
+ * enum {
+ * COLUMN_STRING,
+ * COLUMN_INT,
+ * COLUMN_BOOLEAN,
+ * N_COLUMNS
+ * };
+ *
+ * {
+ * GtkListStore *list_store;
+ * GtkTreePath *path;
+ * GtkTreeIter iter;
+ * gint i;
+ *
+ * list_store = gtk_list_store_new (N_COLUMNS,
+ * G_TYPE_STRING,
+ * G_TYPE_INT,
+ * G_TYPE_BOOLEAN);
+ *
+ * for (i = 0; i < 10; i++)
+ * {
+ * gchar *some_data;
+ *
+ * some_data = get_some_data (i);
+ *
+ * // Add a new row to the model
+ * gtk_list_store_append (list_store, &iter);
+ * gtk_list_store_set (list_store, &iter,
+ * COLUMN_STRING, some_data,
+ * COLUMN_INT, i,
+ * COLUMN_BOOLEAN, FALSE,
+ * -1);
+ *
+ * /<!---->* As the store will keep a copy of the string internally, we
+ * * free some_data.
+ * *<!---->/
+ * g_free (some_data);
+ * }
+ *
+ * // Modify a particular row
+ * path = gtk_tree_path_new_from_string ("4");
+ * gtk_tree_model_get_iter (GTK_TREE_MODEL (list_store),
+ * &iter,
+ * path);
+ * gtk_tree_path_free (path);
+ * gtk_list_store_set (list_store, &iter,
+ * COLUMN_BOOLEAN, TRUE,
+ * -1);
+ * }
+ * </programlisting>
+ * </example>
+ *
+ * <refsect2>
+ * <title>Performance Considerations</title>
+ * Internally, the #GtkListStore was implemented with a linked list with a
+ * tail pointer prior to GTK+ 2.6. As a result, it was fast at data
+ * insertion and deletion, and not fast at random data access. The
+ * #GtkListStore sets the #GTK_TREE_MODEL_ITERS_PERSIST flag, which means
+ * that #GtkTreeIter<!-- -->s can be cached while the row exists. Thus, if
+ * access to a particular row is needed often and your code is expected to
+ * run on older versions of GTK+, it is worth keeping the iter around.
+ * </refsect2>
+ * <refsect2>
+ * <title>Atomic Operations</title>
+ * It is important to note that only the methods
+ * gtk_list_store_insert_with_values() and gtk_list_store_insert_with_valuesv()
+ * are atomic, in the sense that the row is being appended to the store and the
+ * values filled in in a single operation with regard to #GtkTreeModel signaling.
+ * In contrast, using e.g. gtk_list_store_append() and then gtk_list_store_set()
+ * will first create a row, which triggers the #GtkTreeModel::row-inserted signal
+ * on #GtkListStore. The row, however, is still empty, and any signal handler
+ * connecting to #GtkTreeModel::row-inserted on this particular store should be prepared
+ * for the situation that the row might be empty. This is especially important
+ * if you are wrapping the #GtkListStore inside a #GtkTreeModelFilter and are
+ * using a #GtkTreeModelFilterVisibleFunc. Using any of the non-atomic operations
+ * to append rows to the #GtkListStore will cause the
+ * #GtkTreeModelFilterVisibleFunc to be visited with an empty row first; the
+ * function must be prepared for that.
+ * </refsect2>
+ * <refsect2 id="GtkListStore-BUILDER-UI">
+ * <title>GtkListStore as GtkBuildable</title>
+ * <para>
+ * The GtkListStore implementation of the GtkBuildable interface allows
+ * to specify the model columns with a <columns> element that may
+ * contain multiple <column> elements, each specifying one model
+ * column. The "type" attribute specifies the data type for the column.
+ *
+ * Additionally, it is possible to specify content for the list store
+ * in the UI definition, with the <data> element. It can contain
+ * multiple <row> elements, each specifying to content for one
+ * row of the list model. Inside a <row>, the <col> elements
+ * specify the content for individual cells.
+ *
+ * Note that it is probably more common to define your models
+ * in the code, and one might consider it a layering violation
+ * to specify the content of a list store in a UI definition,
+ * <emphasis>data</emphasis>, not <emphasis>presentation</emphasis>,
+ * and common wisdom is to separate the two, as far as possible.
+ * <!-- FIXME a bit inconclusive -->
+ *
+ * <example>
+ * <title>A UI Definition fragment for a list store</title>
+ * <programlisting><![CDATA[
+ * <object class="GtkListStore">
