Description: Reference for Gtk.SliceListModel

### Class

# GtkSliceListModel

since: 4.0

#### 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.

since: 2.0

##### 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.
