QListWidget: QAbstractItemView calls setCurrentIndex in focusInEvent which causes an extra currentRowChanged signal if the focus is caused by mouse-clicking on the index other than the first one.

If user clicks one item in the QListWidget other than the first one, two currentRowChanged signals are emitted, because one is emitted in QAbstractItemView::focusInEvent to set the first item to be current item, and then current item changes from the first one to the one clicked.

Should consider the focus reason in the focusInEvent.
