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 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.

Signals

Signals inherited from GObject (1)
GObject.Object::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)
