void QAbstractItemView::selectionChanged ( const QItemSelection & selected, const QItemSelection & deselected )   [virtual protected slot]

To copy to clipboard, switch view to plain text mode 

This slot is called when the selection is changed. The previous selection (which may be empty), is specified by deselected, and the new selection by selected.

See also setSelection().
