 /**
+ * SECTION:glistmodel
+ * @title: GListModel
+ * @short_description: An interface describing a dynamic list of objects
+ * @include: gio/gio.h
+ * @see_also: #GListStore
+ *
+ * #GListModel is an interface that represents a mutable list of
+ * #GObjects. Its main intention is as a model for various widgets in
+ * user interfaces, such as list views, but it can also be used as a
+ * convenient method of returning lists of data, with support for
+ * updates.
+ *
+ * Each object in the list may also report changes in itself via some
+ * mechanism (normally the #GObject::notify signal).  Taken together
+ * with the #GListModel::items-changed signal, this provides for a list
+ * that can change its membership, and in which the members can change
+ * their individual properties.
+ *
+ * A good example would be the list of visible wireless network access
+ * points, where each access point can report dynamic properties such as
+ * signal strength.
+ *
+ * It is important to note that the #GListModel itself does not report
+ * changes to the individual items.  It only reports changes to the list
+ * membership.  If you want to observe changes to the objects themselves
+ * then you need to connect signals to the objects that you are
+ * interested in.
+ *
+ * All items in a #GListModel are of (or derived from) the same type.
+ * g_list_model_get_item_type() returns that type.  The type may be an
+ * interface, in which case all objects in the list must implement it.
+ *
+ * The semantics are close to that of an array:
+ * g_list_model_get_length() returns the number of items in the list and
+ * g_list_model_get_item() returns an item at a (0-based) position. In
+ * order to allow implementations to calculate the list length lazily,
+ * you can also iterate over items: starting from 0, repeatedly call
+ * g_list_model_get_item() until it returns %NULL.
+ *
+ * An implementation may create objects lazily, but must take care to
+ * return the same object for a given position until all references to
+ * it are gone.
+ *
+ * On the other side, a consumer is expected only to hold references on
+ * objects that are currently "user visible", in order to faciliate the
+ * maximum level of laziness in the implementation of the list and to
+ * reduce the required number of signal connections at a given time.
+ *
+ * This interface is intended only to be used from a single thread.  The
+ * thread in which it is appropriate to use it depends on the particular
+ * implementation, but typically it will be from the thread that owns
+ * the [thread-default main context][g-main-context-push-thread-default]
+ * in effect at the time that the model was created.
