Delegate customization issue

[qmad]

I am overriding the paint(...) function of QStyledItemDelegate as follows. I just want to display a red cross in all cells of a column on a QTableView. (I am applying this delegate for 3rd column only) What is wrong with the code? I am not able to see the cross mark in the cell. Instead I can see a red spot at top left corner of the table

void CrossDelegate::paint(QPainter *painter,
const QStyleOptionViewItem &option,
const QModelIndex &index) const
{
painter->save();
painter->setRenderHint(QPainter::Antialiasing, true);
painter->setPen(QPen(Qt::red));
painter->setBrush(option.palette.foreground());
painter->drawLine(QPointF(0.0, 1.0) ,QPointF(1.0, 0.0) );
painter->drawLine(QPointF(0.0, 0.0) ,QPointF(1.0, 1.0) );
painter->restore();
}

Hi and welcome
the painter is for whole widget. whole area.
there should be a option.rect that should be the cell area.
so the 0,0 would be rect.left, rect.top

here is an example shown:
