    /// 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 and drop][gtk3-GtkTreeView-drag-and-drop]

    /// The [`ListStore`][crate::ListStore] 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 `GObjects` 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
    /// [`row_changed`][struct@crate::TreeModel#row_changed] signal. This most commonly affects lists with

    /// # Performance Considerations
    ///
    /// Internally, the [`ListStore`][crate::ListStore] 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
    /// [`ListStore`][crate::ListStore] sets the [`TreeModelFlags::ITERS_PERSIST`][crate::TreeModelFlags::ITERS_PERSIST] flag, which means
    /// that `GtkTreeIters` 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. [`GtkListStoreExt::append()`][crate::prelude::GtkListStoreExt::append()] and then [`GtkListStoreExtManual::set()`][crate::prelude::GtkListStoreExtManual::set()]
    /// will first create a row, which triggers the [`row-inserted`][struct@crate::TreeModel#row-inserted] signal
    /// on [`ListStore`][crate::ListStore]. The row, however, is still empty, and any signal handler
    /// connecting to [`row-inserted`][struct@crate::TreeModel#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 [`TreeModelFilter`][crate::TreeModelFilter] and are
    /// using a `GtkTreeModelFilterVisibleFunc`. Using any of the non-atomic operations
    /// to append rows to the [`ListStore`][crate::ListStore] will cause the
    /// `GtkTreeModelFilterVisibleFunc` to be visited with an empty row first; the
    /// function must be prepared for that.
    ///
    /// # GtkListStore as GtkBuildable
    ///
    /// 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, 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:
    ///
    ///
    ///
    /// **⚠️ The following code is in xml ⚠️**
    ///
    /// ```xml
    /// <object class="GtkListStore">
    ///   <columns>
    ///     <column type="gchararray"/>
    ///     <column type="gchararray"/>
