QTreeView is what you want. Setting rootIsDecorated to false will make it 
look like a multi-column list (if there are no nested subitems).

Make your reimplemented QAbstractItemModel's data() method return the icon 
when the requested role is Qt::DecorationRole. The preferred background 
color can be returned by the model if Qt::BackgroundRole is requested. Also 
have a look at http://doc.trolltech.com/4.5/model-view-model.html#item-
roles.
