class Gtk::TreeListRowSorter

Overview

Gtk::TreeListRowSorter is a special-purpose sorter that will apply a given sorter to the levels in a tree.

Here is an example for setting up a column view with a tree model and a Gtk::TreeListSorter:

WARNING ⚠️ The following code is in c ⚠️

column_sorter = gtk_column_view_get_sorter (view);
sorter = gtk_tree_list_row_sorter_new (g_object_ref (column_sorter));
sort_model = gtk_sort_list_model_new (tree_model, sorter);
selection = gtk_single_selection_new (sort_model);
gtk_column_view_set_model (view, G_LIST_MODEL (selection));

Constructor Detail

def self.new(sorter : Gtk::Sorter | Nil) : self #

Create a special-purpose sorter that applies the sorting of sorter to the levels of a Gtk::TreeListModel.

Note that this sorter relies on Gtk::TreeListModel#passthrough being false as it can only sort Gtk::TreeListRows.

def self.new #

Initialize a new TreeListRowSorter.

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def sorter : Gtk::Sorter | Nil #

Returns the sorter used by self.


[View source]
def sorter=(sorter : Gtk::Sorter | Nil) : Nil #

Sets the sorter to use for items with the same parent.

This sorter will be passed the Gtk::TreeListRow#item of the tree list rows passed to self.
