If - and only if ;-) - setting

   view->setSelectionBehavior (QAbstractItemView::SelectItems);

does not help, this _might_ be an option:

1) Create a custom selection model class where you overload the two 
select() methods:

class MySelectionModel : public QItemSelectionModel
{
public:
     MySelectionModel (QAbstractItemModel *model)
         : QItemSelectionModel (model)
     { }
     MySelectionModel (QAbstractItemModel *model, QObject *parent)
         : QItemSelectionModel (model, parent)
     { }

     virtual void select (const QModelIndex &index
         , QItemSelectionModel::SelectionFlags command)
     {
         command &= ~QItemSelectionModel::Columns;
         QItemSelectionModel::select (index, command);
     }

     virtual void select (const QItemSelection &selection
         , QItemSelectionModel::SelectionFlags command)
     {
         command &= ~QItemSelectionModel::Columns;
         QItemSelectionModel::select (selection, command);
     }
};


2) Assign an instance of this selection model to your view:

view->setSelectionModel (new MySelectionModel (view->model ()));


Maybe you have to play a little with your selection model. You might 
also want to play with different settings of SelectionBehavior and/or 
SelectionMode.
