    /// for a [`TreeView`][crate::TreeView] widget.  The [`TreeSelection`][crate::TreeSelection] object is
    /// automatically created when a new [`TreeView`][crate::TreeView] widget is created, and
    /// cannot exist independently of this widget.  The primary reason the
    /// [`TreeSelection`][crate::TreeSelection] objects exists is for cleanliness of code and API.
    /// That is, there is no conceptual reason all these functions could not be
    /// methods on the [`TreeView`][crate::TreeView] widget instead of a separate function.
    ///
    /// The [`TreeSelection`][crate::TreeSelection] object is gotten from a [`TreeView`][crate::TreeView] by calling
    /// gtk_tree_view_get_selection().  It can be manipulated to check the
    /// selection status of the tree, as well as select and deselect individual
    /// rows.  Selection is done completely view side.  As a result, multiple
    /// views of the same model can have completely different selections.
    /// Additionally, you cannot change the selection of a row on the model that
    /// is not currently displayed by the view without expanding its parents
    /// first.
    ///
    /// One of the important things to remember when monitoring the selection of
    /// a view is that the [`TreeSelection`][crate::TreeSelection]::changed signal is mostly a hint.
    /// That is, it may only emit one signal when a range of rows is selected.
    /// Additionally, it may on occasion emit a [`TreeSelection`][crate::TreeSelection]::changed signal
    /// when nothing has happened (mostly as a result of programmers calling
    /// select_row on an already selected row).
