+ * @Title: GtkTreeModel
+ * @Short_description: The tree interface used by GtkTreeView
+ * @See_also: #GtkTreeView, #GtkTreeStore, #GtkListStore,
+ * <link linkend="gtk-GtkTreeView-drag-and-drop">GtkTreeDnd</link>,
+ * #GtkTreeSortable
+ *
+ * The #GtkTreeModel interface defines a generic tree interface for
+ * use by the #GtkTreeView widget. It is an abstract interface, and
+ * is designed to be usable with any appropriate data structure. The
+ * programmer just has to implement this interface on their own data
+ * type for it to be viewable by a #GtkTreeView widget.
+ *
+ * The model is represented as a hierarchical tree of strongly-typed,
+ * columned data. In other words, the model can be seen as a tree where
+ * every node has different values depending on which column is being
+ * queried. The type of data found in a column is determined by using
+ * the GType system (ie. #G_TYPE_INT, #GTK_TYPE_BUTTON, #G_TYPE_POINTER,
+ * etc). The types are homogeneous per column across all nodes. It is
+ * important to note that this interface only provides a way of examining
+ * a model and observing changes. The implementation of each individual
+ * model decides how and if changes are made.
+ *
+ * In order to make life simpler for programmers who do not need to
+ * write their own specialized model, two generic models are provided
+ * — the #GtkTreeStore and the #GtkListStore. To use these, the
+ * developer simply pushes data into these models as necessary. These
+ * models provide the data structure as well as all appropriate tree
+ * interfaces. As a result, implementing drag and drop, sorting, and
+ * storing data is trivial. For the vast majority of trees and lists,
+ * these two models are sufficient.
+ *
+ * Models are accessed on a node/column level of granularity. One can
+ * query for the value of a model at a certain node and a certain
+ * column on that node. There are two structures used to reference
+ * a particular node in a model. They are the #GtkTreePath and the
+ * #GtkTreeIter<footnote><para>Here, <abbrev>iter</abbrev> is short
+ * for <quote>iterator</quote></para></footnote>. Most of the interface
+ * consists of operations on a #GtkTreeIter.
+ *
+ * A path is essentially a potential node. It is a location on a model
+ * that may or may not actually correspond to a node on a specific
+ * model. The #GtkTreePath struct can be converted into either an
+ * array of unsigned integers or a string. The string form is a list
+ * of numbers separated by a colon. Each number refers to the offset
+ * at that level. Thus, the path <quote>0</quote> refers to the root
+ * node and the path <quote>2:4</quote> refers to the fifth child of
+ * the third node.
+ *
+ * By contrast, a #GtkTreeIter is a reference to a specific node on
+ * a specific model. It is a generic struct with an integer and three
+ * generic pointers. These are filled in by the model in a model-specific
+ * way. One can convert a path to an iterator by calling
+ * gtk_tree_model_get_iter(). These iterators are the primary way
+ * of accessing a model and are similar to the iterators used by
+ * #GtkTextBuffer. They are generally statically allocated on the
+ * stack and only used for a short time. The model interface defines
+ * a set of operations using them for navigating the model.
+ *
+ * It is expected that models fill in the iterator with private data.
+ * For example, the #GtkListStore model, which is internally a simple
+ * linked list, stores a list node in one of the pointers. The
+ * #GtkTreeModelSort stores an array and an offset in two of the
+ * pointers. Additionally, there is an integer field. This field is
+ * generally filled with a unique stamp per model. This stamp is for
+ * catching errors resulting from using invalid iterators with a model.
+ *
+ * The lifecycle of an iterator can be a little confusing at first.
+ * Iterators are expected to always be valid for as long as the model
+ * is unchanged (and doesn't emit a signal). The model is considered
+ * to own all outstanding iterators and nothing needs to be done to
+ * free them from the user's point of view. Additionally, some models
+ * guarantee that an iterator is valid for as long as the node it refers
+ * to is valid (most notably the #GtkTreeStore and #GtkListStore).
+ * Although generally uninteresting, as one always has to allow for
+ * the case where iterators do not persist beyond a signal, some very
+ * important performance enhancements were made in the sort model.
+ * As a result, the #GTK_TREE_MODEL_ITERS_PERSIST flag was added to
+ * indicate this behavior.
+ *
+ * To help show some common operation of a model, some examples are
+ * provided. The first example shows three ways of getting the iter at
+ * the location <quote>3:2:5</quote>. While the first method shown is
+ * easier, the second is much more common, as you often get paths from
+ * callbacks.
+ *
+ * <example>
+ * <title>Acquiring a <structname>GtkTreeIter</structname></title>
+ * <programlisting>
+ * /* Three ways of getting the iter pointing to the location */
+ * GtkTreePath *path;
+ * GtkTreeIter iter;
+ * GtkTreeIter parent_iter;
+ *
+ * /* get the iterator from a string */
+ * gtk_tree_model_get_iter_from_string (model, &iter, "3:2:5");
+ *
+ * /* get the iterator from a path */
+ * path = gtk_tree_path_new_from_string ("3:2:5");
+ * gtk_tree_model_get_iter (model, &iter, path);
+ * gtk_tree_path_free (path);
+ *
+ * /* walk the tree to find the iterator */
+ * gtk_tree_model_iter_nth_child (model, &iter, NULL, 3);
+ * parent_iter = iter;
+ * gtk_tree_model_iter_nth_child (model, &iter, &parent_iter, 2);
+ * parent_iter = iter;
+ * gtk_tree_model_iter_nth_child (model, &iter, &parent_iter, 5);
+ * </programlisting>
+ * </example>
+ *
+ * This second example shows a quick way of iterating through a list
+ * and getting a string and an integer from each row. The
+ * <function>populate_model</function> function used below is not
+ * shown, as it is specific to the #GtkListStore. For information on
+ * how to write such a function, see the #GtkListStore documentation.
+ *
+ * <example>
+ * <title>Reading data from a <structname>GtkTreeModel</structname></title>
+ * <programlisting>
+ * enum
+ * {
+ * STRING_COLUMN,
+ * INT_COLUMN,
+ * N_COLUMNS
+ * };
+ *
+ * ...
+ *
+ * GtkTreeModel *list_store;
+ * GtkTreeIter iter;
+ * gboolean valid;
+ * gint row_count = 0;
+ *
+ * /* make a new list_store */
+ * list_store = gtk_list_store_new (N_COLUMNS, G_TYPE_STRING, G_TYPE_INT);
+ *
+ * /* Fill the list store with data */
+ * populate_model (list_store);
+ *
+ * /* Get the first iter in the list */
+ * valid = gtk_tree_model_get_iter_first (list_store, &iter);
+ *
+ * while (valid)
+ * {
+ * /* Walk through the list, reading each row */
+ * gchar *str_data;
+ * gint int_data;
+ *
+ * /* Make sure you terminate calls to gtk_tree_model_get()
+ * * with a '-1' value
+ * */
+ * gtk_tree_model_get (list_store, &iter,
+ * STRING_COLUMN, &str_data,
+ * INT_COLUMN, &int_data,
+ * -1);
+ *
+ * /* Do something with the data */
+ * g_print ("Row %d: (%s,%d)\n", row_count, str_data, int_data);
+ * g_free (str_data);
+ *
+ * row_count++;
+ * valid = gtk_tree_model_iter_next (list_store, &iter);
+ * }
+ * </programlisting>
+ * </example>
+ *
+ * The #GtkTreeModel interface contains two methods for reference
+ * counting: gtk_tree_model_ref_node() and gtk_tree_model_unref_node().
+ * These two methods are optional to implement. The reference counting
+ * is meant as a way for views to let models know when nodes are being
+ * displayed. #GtkTreeView will take a reference on a node when it is
+ * visible, which means the node is either in the toplevel or expanded.
+ * Being displayed does not mean that the node is currently directly
+ * visible to the user in the viewport. Based on this reference counting
+ * scheme a caching model, for example, can decide whether or not to cache
+ * a node based on the reference count. A file-system based model would
+ * not want to keep the entire file hierarchy in memory, but just the
+ * folders that are currently expanded in every current view.
+ *
+ * When working with reference counting, the following rules must be taken
+ * into account:
+ * <itemizedlist>
+ * <listitem><para>Never take a reference on a node without owning a
+ * reference on its parent. This means that all parent nodes of a referenced
+ * node must be referenced as well.</para></listitem>
+ * <listitem><para>Outstanding references on a deleted node are not released.
+ * This is not possible because the node has already been deleted by the
+ * time the row-deleted signal is received.
+ * </para></listitem>
+ * <listitem><para>Models are not obligated to emit a signal on rows of
+ * which none of its siblings are referenced. To phrase this differently,
+ * signals are only required for levels in which nodes are referenced. For
+ * the root level however, signals must be emitted at all times (however the
+ * root level is always referenced when any view is attached).
+ * </para></listitem>
+ * </itemizedlist>
