SelectionModel.getSelectionInRange

gtk.bitset.Bitset getSelectionInRange(uint position, uint nItems)

Gets the set of selected items in a range.

This function is an optimization for [gtk.selection_model.SelectionModel.getSelection] when you are only interested in part of the model's selected state. A common use case is in response to the signalGtk.SelectionModel::selection-changed signal.

Parameters

`position`	start of the queried range
`nItems`	number of items in the queried range

Returns

A [gtk.bitset.Bitset] that matches the selection state

for the given range with all other values being undefined. The bitset must not be modified.
