``GtkCustomSorter`` is a ``GtkSorter`` implementation that sorts via a callback
function.





Methods
-------

.. rst-class:: interim-class

.. class:: CustomSorter
   :no-index:


   .. classmethod:: new(sort_func, user_data=None)

      






      :param sort_func: 

      :param user_data: 




   .. method:: set_sort_func(sort_func, user_data=None)

      Sets (or unsets) the function used for sorting items.

      If ``sort_func`` is :const:`None`, all items are considered equal.

      If the sort func changes its sorting behavior,
      :func:`~gi.repository.Gtk.Sorter.changed` needs to be called.

      If a previous function was set, its ``user_destroy`` will be
      called now.







      :param sort_func: function to sort items


      :param user_data: user data to pass to ``match_func``
