Grid QTableView horizontal only

[estanisgeyer]

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,

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);
}

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);
}
