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 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)

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

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.
