    /// ## Coordinate systems in GtkTreeView API
    ///
    /// Several different coordinate systems are exposed in the [`TreeView`][crate::TreeView] API.
    /// These are:
    ///
    /// ![](tree-view-coordinates.png)
    ///
    /// - Widget coordinates: Coordinates relative to the widget (usually `widget->window`).
    ///
    /// - Bin window coordinates: Coordinates relative to the window that GtkTreeView renders to.
    ///
    /// - Tree coordinates: Coordinates relative to the entire scrollable area of GtkTreeView. These
    ///   coordinates start at (0, 0) for row 0 of the tree.
    ///
    /// Several functions are available for converting between the different
    /// coordinate systems.  The most common translations are between widget and bin
    /// window coordinates and between bin window and tree coordinates. For the
    /// former you can use [`TreeViewExt::convert_widget_to_bin_window_coords()`][crate::prelude::TreeViewExt::convert_widget_to_bin_window_coords()]
    /// (and vice versa), for the latter [`TreeViewExt::convert_bin_window_to_tree_coords()`][crate::prelude::TreeViewExt::convert_bin_window_to_tree_coords()]
    /// (and vice versa).
    ///
    /// ## [`TreeView`][crate::TreeView] as [`Buildable`][crate::Buildable]
    ///
    /// The [`TreeView`][crate::TreeView] implementation of the [`Buildable`][crate::Buildable] interface accepts
