Gtk.Filter
Description
[src]
class Gtk.Filter : GObject.Object
/* No available fields */
Describes the filtering to be performed by a
GtkFilterListModel
The model will use the filter to determine if it should include items
or not by calling
gtk_filter_match()
for each item and only
keeping the ones that the function returns true for.
Filters may change what items they match through their lifetime. In that
case, they will emit the
GtkFilter::changed
signal to notify
that previous filter results are no longer valid and that items should
be checked again via
gtk_filter_match()
GTK
provides various pre-made filter implementations for common filtering
operations. These filters often include properties that can be linked to
various widgets to easily allow searches.
However, in particular for large lists or complex search methods, it is
also possible to subclass
GtkFilter
and provide one’s own filter.
