Struct gtk4::TreeListRowSorter[][src]

pub struct TreeListRowSorter(_);
Expand description

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 GtkTreeListSorter:

⚠️ 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));

Implements

SorterExt, glib::ObjectExt

Implementations

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

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

sorter

a Sorter, or None

Returns

a new TreeListRowSorter

Returns the sorter used by self.

Returns

the sorter used

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

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

sorter

The sorter to use, or None
