In the above file an event filter is installed on vertical scroll bar  
in ListView::setSmoothScrolling(bool) and events to that scroll bar  
is interpreted in ListView::eventFilter(QObject*, QEvent*) see the  
line containing "style().querySubControl()" there. This is probably  
the most appropriate way of handling such situation in Qt3, didn't  
check for Qt4 yet.
