QStyledItemDelegate - style sheet not working

[tomixer]

Hi there,

I want to put QProgressBar into tableview, so i made my own delegate based on QStyledItemDelegate. In documentation of QStyledItemDelegate its written, that it should work with defined style sheet. I defined it in designer. It works for progressbar, that is not in list, but i doesn't work in qtableview.
My enviroment: QT 4.6.3 on Kubuntu 10.04 amd64.

Anyone knows solution on that?

code of my paint function:

void CProgressbarDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QStyleOptionProgressBar oProgressBarStyle;
    oProgressBarStyle.rect = option.rect;
    oProgressBarStyle.minimum = 0;
    oProgressBarStyle.maximum = 100;
    oProgressBarStyle.progress = index.model()->data(index, Qt::DisplayRole).toInt();
    oProgressBarStyle.textAlignment = Qt::AlignHCenter;
    oProgressBarStyle.textVisible = true;
    oProgressBarStyle.text = QString::number(oProgressBarStyle.progress)+"%";
 
    QApplication::style()->drawControl(QStyle::CE_ProgressBar, &oProgressBarStyle, painter, m_pWidget);
}

void CProgressbarDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QStyleOptionProgressBar oProgressBarStyle;
    oProgressBarStyle.rect = option.rect;
    oProgressBarStyle.minimum = 0;
    oProgressBarStyle.maximum = 100;
    oProgressBarStyle.progress = index.model()->data(index, Qt::DisplayRole).toInt();
    oProgressBarStyle.textAlignment = Qt::AlignHCenter;
    oProgressBarStyle.textVisible = true;
    oProgressBarStyle.text = QString::number(oProgressBarStyle.progress)+"%";

    QApplication::style()->drawControl(QStyle::CE_ProgressBar, &oProgressBarStyle, painter, m_pWidget);
}

To copy to clipboard, switch view to plain text mode 

m_pWidget was QTableView pointer and MainWindow pointer, even without QWidget it doesn't work.
