When QStyledItemDelegate was introduced in Qt 4.4, the source code for the Star Delegate example was changed, but the documentation at http://doc.trolltech.com/4.4/itemviews-stardelegate.html was not. The docs for Qt 4.4, 4.5 and 4.6 all still say "StarDelegate inherits QItemDelegate" and make many references to QItemDelegate, when it now inherits QStyledItemDelegate.

Since this example may most likely be read by people who're unfamiliar with delegate design, this may cause some confusion.
