+ * \param current This item will be the current item.
+ * \param expectedSelection Expected selection after anchor and current are set.
+ * \param changeType Type of the change that is done then:
+ * - NoChange
+ * - InsertItems -> data.at(0) provides the KItemRangeList. \sa KItemListSelectionManager::itemsInserted()
+ * - RemoveItems -> data.at(0) provides the KItemRangeList. \sa KItemListSelectionManager::itemsRemoved()
+ * - MoveItems -> data.at(0) provides the KItemRange containing the original indices,
+ * data.at(1) provides the list containing the new indices
+ * \sa KItemListSelectionManager::itemsMoved(), KItemModelBase::itemsMoved()
+ * - EndAnchoredSelection
+ * - SetSelected -> data.at(0) provides the index where the selection process starts,
+ * data.at(1) provides the number of indices to be selected,
+ * data.at(2) provides the selection mode.
+ * \sa KItemListSelectionManager::setSelected()
+ * \param data A list of QVariants which will be cast to the arguments needed for the chosen ChangeType (see above).
