use QProxyStyle, this function will rotate 180 for text, and you can rotate 90。

void MyProxyStyle::drawItemText( QPainter* painter,
                                 const QRect&,
                                 int alignment,
                                 const QPalette& palette,
                                 bool enabled,
                                 const QString& text,
                                 QPalette::ColorRole textRole ) const
{
    painter->save();
    painter->translate(160,50);
    painter->rotate(-180);

    QCommonStyle::drawItemText( painter,
                                rectangle,
                                alignment,
                                palette,
                                enabled,
                                text,
                                textRole );

    painter->restore();
}
