Problem with selection in QTableWidget!

In all cases of selection (by mouse or keyboard) in QTableWidget, at first currentIndex() change,
then selectedRows() change.
But there is another case when this sequence dont work:
At first selectedRows() change, then currentIndex() change.
Example:
selecting only by mouse several elements on QTableWidget

How to:
example show currentRow() when selection changed
only in one case currentRow() returns previous value
when you selecting only by mouse several elements on QTableWidget
