The reason that you can't embed a Widget inside a QListViewItem is because it 
is not a QWidget(or even a QObject).  Trolltech did this so that a QListView 
could hold more elements without getting really slow.  Check out the source 
for QCheckListItem if you want to see how they put in a check box.
