FilterChange
===================================================================

.. currentmodule:: gi.repository.Gtk





.. class:: FilterChange
   :no-contents-entry:






Describes changes in a filter in more detail and allows objects
using the filter to optimize refiltering items.

If you are writing an implementation and are not sure which
value to pass, ``GTK_FILTER_CHANGE_DIFFERENT`` is always a correct
choice.

New values may be added in the future.












Fields
------

.. rst-class:: interim-class

.. class:: FilterChange
   :no-index:
   

   .. attribute:: DIFFERENT

      The filter change cannot be
      described with any of the other enumeration values






   .. attribute:: DIFFERENT_REWATCH

      Similar to :obj:`~gi.repository.Gtk.FilterChange.DIFFERENT`\,
      but signs that item watches should be recreated. This is used by
      :obj:`~gi.repository.Gtk.FilterListModel` to keep the list up-to-date when items
      change.


      .. versionadded:: 4.20





   .. attribute:: LESS_STRICT

      The filter is less strict than
      it was before: All items that it used to return true
      still return true, others now may, too.






   .. attribute:: LESS_STRICT_REWATCH

      Similar to :obj:`~gi.repository.Gtk.FilterChange.LESS_STRICT`\,
      but signs that item watches should be recreated. This is used by
      :obj:`~gi.repository.Gtk.FilterListModel` to keep the list up-to-date when items
      change.


      .. versionadded:: 4.20





   .. attribute:: MORE_STRICT

      The filter is more strict than
      it was before: All items that it used to return false
      still return false, others now may, too.






   .. attribute:: MORE_STRICT_REWATCH

      Similar to :obj:`~gi.repository.Gtk.FilterChange.MORE_STRICT`\,
      but signs that item watches should be recreated. This is used by
