Class

GtkSliceListModel

Description [src]

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

GtkSliceListModel is a list model that presents a slice of another model.

This is useful when implementing paging by setting the size to the number of elements per page and updating the offset whenever a different page is opened.

GtkSliceListModel passes through sections from the underlying 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)
