Class
GtkSortListModel
Description [src]
final class Gtk.SortListModel : GObject.Object {
/* No available fields */
}
A GListModel
that sorts the elements of an underlying model
according to a GtkSorter
.
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.
Constructors
gtk_sort_list_model_new
Creates a new sort list model that uses the sorter
to sort model
.
Instance methods
gtk_sort_list_model_get_incremental
Returns whether incremental sorting is enabled.
gtk_sort_list_model_get_model
Gets the model currently sorted or NULL
if none.
gtk_sort_list_model_get_pending
Estimates progress of an ongoing sorting operation.
gtk_sort_list_model_get_sorter
Gets the sorter that is used to sort self
.
gtk_sort_list_model_set_incremental
Sets the sort model to do an incremental sort.
gtk_sort_list_model_set_model
Sets the model to be sorted.
gtk_sort_list_model_set_sorter
Sets a new sorter on self
.

. If position
is greater than the number of
items in list
, NULL
is returned.
Available since: 2.44
g_list_model_get_item_type
Gets the type of the items in list
. All items returned from
g_list_model_get_type()
are of that type or a subtype, or are an
implementation of that interface.
Available since: 2.44
g_list_model_get_n_items
Gets the number of items in list
.
Available since: 2.44
g_list_model_get_object
Get the item at position
. If position
is greater than the number of
items in list
, NULL
is returned.
Available since: 2.44
g_list_model_items_changed
Emits the GListModel::items-changed
signal on list
.

If the model should sort items incrementally.
Gtk.SortListModel:model
The model being sorted.
Gtk.SortListModel:pending
Estimate of unsorted items remaining.
Gtk.SortListModel:sorter
The sorter for this model.
Signals
Signals inherited from GObject (1)
GObject.Object::notify

Signals inherited from GListModel (1)
Gio.ListModel::items-changed
This signal is emitted whenever items were added to or removed

. At position
