QTableView, setting a cell's font and background colour

Question

I am using QTableView and QStandardItemModel and I'm trying to colour a row with the font remaining black.

I am using my delegate class's paint method:

void Delegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QBrush brush(Qt::red, Qt::SolidPattern);
    painter->setBackground(brush);
}

This does not work at all and it makes the text within each cell transparent. What am I doing wrong here?

[EDIT] I've used painter->fillRect(option.rect, brush); as well but it makes the cell background and text the same colour.

Your Delegate should inherit QStyledItemDelegate.

Your paint event probably should look like this:

void Delegate::paint(QPainter *painter,
                     const QStyleOptionViewItem &option,
                     const QModelIndex &index) const
{
    QStyleOptionViewItem op(option);

    if (index.row() == 2) {
        op.font.setBold(true);
        op.palette.setColor(QPalette::Normal, QPalette::Background, Qt::black);
        op.palette.setColor(QPalette::Normal, QPalette::Foreground, Qt::white);
    }
    QStyledItemDelegate::paint(painter, op, index);
}
