Hi,

With the property showgrid can enable and disable the grid in a QTableView. How can I do to display a grid with only horizontal lines? Is it possible?

Thanks,

Marcelo E. Geyer

AFAIK, it's not possible but you can create a custom delegate where you paint it the way you want.


class CustomDelegate : public QStyledItemDelegate
{
Q_OBJECT

public:
CustomDelegate(QObject *parent = 0);
void paint(QPainter *painter, const QStyleOptionViewItem& option, const QModelIndex& index ) const;
};


void CustomDelegate::paint(QPainter *painter, const QStyleOptionViewItem& option, const QModelIndex& index ) const
{
// Paint the line
painter->save();
painter->setPen(QColor(0, 0, 0, 220));
painter->drawLine(option.rect.bottomLeft(), option.rect.bottomRight());
painter->restore();

// Now paint the normal cell contents
this->QStyledItemDelegate::paint(painter, option, index);
}
