                case 5: return "Prix";          break;
                case 6: return "Prix vente";    break;
                default:
                    return QString("Column %1").arg(section + 1);
                    break;
                }
        }
 
        return QVariant();
    }
};
 
// Handles Vertical header
class Header : public QHeaderView
{
    Q_OBJECT
public:
    explicit Header(QWidget * parent)
        : QHeaderView(Qt::Vertical, parent)
        , mSelectedIndex(-1)
    {
        setMinimumWidth(QImage("imgs/arrow.png").width());
    }
 
public slots:
    void changeCurrent(const QModelIndex & current, const QModelIndex & previous)
    {
        int section = current.row();
 
        if(mSelectedIndex != section)
        {
            mSelectedIndex = section;
            viewport()->update();
        }
    }
 
protected:
    void paintSection(QPainter *painter, const QRect &rect, int logicalIndex) const
    {
        painter->save();
        if(mSelectedIndex > -1)
        {
            if(mSelectedIndex == logicalIndex)
                if(!isSectionHidden(logicalIndex))
                    painter->drawImage(rect, QImage("imgs/arrow.png"));
        }
        painter->restore();
    }
 
private:
    int mSelectedIndex;
};
 
//Usage
QSqlQueryModel model;
 
HeaderModel headerModel;
headerModel.setSourceModel(&model);
 
QTableView tableView;
Header * header = new Header(&tableView);
tableView.setModel(&headerModel);
tableView.connect(tableView.selectionModel(), SIGNAL(currentChanged(QModelIndex,QModelIndex)), header, SLOT(changeCurrent(QModelIndex,QModelIndex)));
tableView.setVerticalHeader(header);
tableView.setSelectionMode(QAbstractItemView::SingleSelection);
tableView.setSelectionBehavior(QAbstractItemView::SelectRows);
tableView.show();

Yes this is working perfectly, but i get hard to resize the icon ,

i tried setFixedWidth() and setFixedHigh() but the icon becomes broken
i want like QtableWidget when we set an icon it resizes automatically

thanks Santosh Reddy :)
