state. A common use case is in response to the [signal@Gtk.SelectionModel:GtkSelectionModel:selection-changed] signal.
Parameters:
| this |
a `GtkSelectionModel` |
| position |
start of the queried range |
| n_items |
number of items in the queried range |
Returns:

A `GtkBitset` that matches the selection state for the given range with all other values being undefined. The bitset must not be modified. |
