get_selection_in_range


Description:

public abstract Bitset get_selection_in_range (uint position, uint n_items)

Gets a set containing a set where the values in the range `[position, position + n_items)` match the selected state of the items in that range.

All values outside that range are undefined.

This function is an optimization for get_selection when you are only interested in part of the model's selected state. A common use case is in response to the selection_changed signal.

Parameters:

this

a SelectionModel

position

start of the queired range

n_items

number of items in the queried range

Returns:

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