changed

Notifies all users of the filter that it has changed.

This emits the signal@Gtk.Filter::changed signal. Users of the filter should then check items again via method@Gtk.Filter.match.

Depending on the @change parameter, not all items need to be changed, but only some. Refer to the enum@Gtk.FilterChange documentation for details.

This function is intended for implementors of GtkFilter subclasses and should not be called from other functions.
