/// A list-like data structure that can be used with the GtkTreeView
///
/// 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 and drop][gtk4-GtkTreeView-drag-and-drop]
/// interfaces.
///
/// 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 `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
/// [`TreeModel`][crate::TreeModel]::row_changed signal. This most commonly affects lists with
/// [`gdk::Texture`][crate::gdk::Texture]s stored.
///
/// An example for creating a simple list store:
///
///
/// **⚠️ The following code is in C ⚠️**
///
/// ```C
/// enum {
/// COLUMN_STRING,
/// COLUMN_INT,
/// COLUMN_BOOLEAN,
/// N_COLUMNS
/// };
///
/// {
/// GtkListStore *list_store;
/// GtkTreePath *path;
/// GtkTreeIter iter;
/// int i;
///
/// list_store = gtk_list_store_new (N_COLUMNS,
/// G_TYPE_STRING,
/// G_TYPE_INT,
/// G_TYPE_BOOLEAN);
///
/// for (i = 0; i < 10; i++)
/// {
/// char *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);
/// }
/// ```
///
/// # 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
/// [`TreeModelFlags::ITERS_PERSIST`][crate::TreeModelFlags::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 [`insert_with_values()`][Self::insert_with_values()]
/// 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. [`append()`][Self::append()] and then [`set()`][Self::set()]
/// will first create a row, which triggers the [`TreeModel`][crate::TreeModel]::row-inserted signal
/// on [`ListStore`][crate::ListStore]. The row, however, is still empty, and any signal handler
/// connecting to [`TreeModel`][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 [`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 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 C ⚠️**
///
/// ```C
/// <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>
/// <col id="0">Johan</col>
/// <col id="1">Dahlin</col>
/// <col id="2">50</col>
/// </row>
/// </data>
/// </object>
/// ```
