    ///
    ///
    /// #### `sort-column-changed`
    ///  The ::sort-column-changed signal is emitted when the sort column
    /// or sort order of @sortable is changed. The signal is emitted before
    /// the contents of @sortable are resorted.
    ///
    ///
    /// <details><summary><h4>TreeModel</h4></summary>
    ///
    ///
    /// #### `row-changed`
    ///  This signal is emitted when a row in the model has changed.
    ///
    ///
    ///
    ///
    /// #### `row-deleted`
    ///  This signal is emitted when a row has been deleted.
    ///
    /// Note that no iterator is passed to the signal handler,
    /// since the row is already deleted.
    ///
    /// This should be called by models after a row has been removed.
    /// The location pointed to by @path should be the location that
    /// the row previously was at. It may not be a valid location anymore.
    ///
    ///
    ///
    ///
    /// #### `row-has-child-toggled`
    ///  This signal is emitted when a row has gotten the first child
    /// row or lost its last child row.
    ///
    ///
    ///
    ///
    /// #### `row-inserted`
    ///  This signal is emitted when a new row has been inserted in
    /// the model.
    ///
    /// Note that the row may still be empty at this point, since
    /// it is a common pattern to first insert an empty row, and
    /// then fill it with the desired values.
    ///
    ///
    ///
    ///
    /// #### `rows-reordered`
    ///  This signal is emitted when the children of a node in the
    /// [`TreeModel`][crate::TreeModel] have been reordered.
    ///
    /// Note that this signal is not emitted
    /// when rows are reordered by DND, since this is implemented
    /// by removing and then reinserting the row.
