Gtk.SelectionModel.get_selection_in_range

### Method

# Gtk SelectionModelget_selection_in_range

#### Declaration [src]

    GtkBitset*
    gtk_selection_model_get_selection_in_range (
      GtkSelectionModel* model,
      guint position,
      guint n_items
    )

#### Description [src]

Gets the set of selected items in a range.

This function is an optimization for `gtk_selection_model_get_selection()` when you are only interested in part of the model’s selected state. A common use case is in response to the `GtkSelectionModel::selection-changed` signal.

#### Parameters

`position`

  Type: `guint`

  Start of the queired range.

`n_items`

  Type: `guint`

  Number of items in the queried range.

#### Return value

Type: `GtkBitset`

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

The caller of the method takes ownership of the data, and is responsible for freeing it.
