Class

GtkSortListModel

Description [src]

final class Gtk.SortListModel : GObject.Object
  implements Gio.ListModel, Gtk.SectionModel {
  /* No available fields */
}

A GListModel that sorts the elements of an underlying model according to a GtkSorter.

The model is a stable sort. If two items compare equal according to the sorter, the one that appears first in the original model will also appear first after sorting. Note that if you change the sorter, the previous order will have no influence on the new order. If you want that, consider using a GtkMultiSorter and appending the previous sorter to it.

The model can be set up to do incremental sorting, so that sorting long lists doesn’t block the UI. See gtk_sort_list_model_set_incremental() for details.

GtkSortListModel is a generic model and because of that it cannot take advantage of any external knowledge when sorting. If you run into performance issues with GtkSortListModel, it is strongly recommended that you write your own sorting list model.

GtkSortListModel allows sorting the items into sections. It implements GtkSectionModel and when GtkSortListModel:section-sorter is set, it will sort all items with that sorter and items comparing equal with it will be put into the same section. The GtkSortListModel:sorter will then be used to sort items inside their sections.

Methods inherited from GObject (43)

Please see GObject for a full list of methods.

Methods inherited from GListModel (5)
g_list_model_get_item

Get the item at position.

g_list_model_get_item_type

Gets the type of the items in list.

g_list_model_get_n_items

Gets the number of items in list.

g_list_model_get_object

Get the item at position.

g_list_model_items_changed

Emits the GListModel::items-changed signal on list.

Methods inherited from GtkSectionModel (2)
gtk_section_model_get_section

Query the section that covers the given position. The number of items in the section can be computed by out_end - out_start.

since: 4.12

gtk_section_model_sections_changed

This function emits the GtkSectionModel::sections-changed signal to notify about changes to sections.

since: 4.12

Properties

Gtk.SortListModel:incremental

If the model should sort items incrementally.

Gtk.SortListModel:item-type

The type of items. See g_list_model_get_item_type().

since: 4.8

Gtk.SortListModel:model

The model being sorted.

Gtk.SortListModel:n-items

The number of items. See g_list_model_get_n_items().

since: 4.8

Gtk.SortListModel:pending

Estimate of unsorted items remaining.

Gtk.SortListModel:section-sorter

The section sorter for this model, if one is set.

since: 4.12

Gtk.SortListModel:sorter

The sorter for this model.

Signals

Signals inherited from GObject (1)
GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Signals inherited from GListModel (1)
GListModel::items-changed

This signal is emitted whenever items were added to or removed from list. At position, removed items were removed and added items were added in their place.

Signals inherited from GtkSectionModel (1)
GtkSectionModel::sections-changed

Emitted when the start-of-section state of some of the items in model changes.

since: 4.12
