    /// The [`ListStore`][crate::ListStore] object is a list model for use with a [`TreeView`][crate::TreeView]
    /// widget.  It implements the [`TreeModel`][crate::TreeModel] interface, and consequentialy,
    /// can use all of the methods available there.  It also implements the
    /// [`TreeSortable`][crate::TreeSortable] interface so it can be sorted by the view.
    /// Finally, it also implements the tree
    /// [drag](iface.TreeDragSource.html) and [drop](iface.TreeDragDest.html)
    /// interfaces.
    ///
    /// The [`ListStore`][crate::ListStore] can accept most `GType`s 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
    /// [`ListStore`][crate::ListStore] 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 [`TreeModelExt::row_changed()`][crate::prelude::TreeModelExt::row_changed()] to emit the
    /// `signal::TreeModel::row_changed` signal. This most commonly affects lists
    /// with [`gdk::Texture`][crate::gdk::Texture]s stored.

    /// # Performance Considerations
    ///
    /// Internally, the [`ListStore`][crate::ListStore] was originally implemented with a linked list
    /// with a tail pointer.  As a result, it was fast at data insertion and deletion,
    /// and not fast at random data access.  The [`ListStore`][crate::ListStore] sets the
    /// `GTK_TREE_MODEL_ITERS_PERSIST` flag, which means that [`TreeIter`][crate::TreeIter]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.
    ///
    /// # Atomic Operations
    ///
    /// 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 [`TreeModel`][crate::TreeModel] 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 [`ListStore`][crate::ListStore]. 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 [`ListStore`][crate::ListStore] inside a [`TreeModel`][crate::TreeModel]Filter and are
    /// using a [`TreeModel`][crate::TreeModel]FilterVisibleFunc. Using any of the non-atomic operations
    /// to append rows to the [`ListStore`][crate::ListStore] will cause the
    /// [`TreeModel`][crate::TreeModel]FilterVisibleFunc to be visited with an empty row first; the
    /// function must be prepared for that.
    ///
    /// # GtkListStore as GtkBuildable
    ///
    /// The GtkListStore implementation of the [`Buildable`][crate::Buildable] 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, data, not presentation, and common wisdom
    /// is to separate the two, as far as possible.
    ///
    /// An example of a UI Definition fragment for a list store:
    ///
    /// ```xml
    /// <object class="GtkListStore">
    ///   <columns>
    ///     <column type="gchararray"/>
    ///     <column type="gchararray"/>
    ///     <column type="gint"/>
    ///   </columns>
    ///   <data>
    ///     <row>
    ///       <col id="0">John</col>
    ///       <col id="1">Doe</col>
    ///       <col id="2">25</col>
    ///     </row>
    ///     <row>
