The #GtkTreeStore object is a list model for use with a #GtkTreeView widget. It implements the #GtkTreeModel interface, and consequentially, can use all of the methods available there. It also implements the #GtkTreeSortable interface so it can be sorted by the view. Finally, it also implements the tree [drag and drop][gtk3-GtkTreeView-drag-and-drop] interfaces.
