Delegate customization issue

[mqt]

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();
}

Use option.rect geometry instead of hard coded values.
Option.rect is the geometry of your delegate.

Ex: painter->drawLine(option.rect.topLeft() , option.rect.bottomRight());
