Position of rows in table

[Lykurg]

QPointF pos = itemAt(1, 0)->pos();

QPointF pos = itemAt(1, 0)->pos();

To copy to clipboard, switch view to plain text mode 

int rowPosition = itemAt(1, 0)->x();

int rowPosition = itemAt(1, 0)->x();

If you could kindly tell us were these QTableWidgetItem::x() and QTableWidgetItem::pos() functions are...

[Slewman]

lol yea, there is no pos() or x() functions in the QTableWidgetItem Class

[Lykurg]

Hey Slewman, for what do you need that information? As I know there is no standard way to get these information. Only one very nasty way comes in my mind. But you don't wanna know it... And maybe you don't need it.

There's QAbstractItemView::visualRect Rest you can try mapping the cordinates.
Hope it helps

I am trying to have a widget follow a row in a QTableWidget as i scroll up and down the list of rows.

Play with QAbstractItemView::visualRect. Map it to global cordindates and you can have your work done.

Lol, yeah... I misunderstood (did not read properly) your question :P (funny, right?)

Anyway, I'm not absolutely sure how sizeHint() for QTableWidgetItem (QTableWidget::itemAt(int, int) returns QTableWidgetItem* you know...) is calculated by item delegate if no explicit one is set.
This is the sizeHint(..) code from item delegate

QSize QItemDelegate::sizeHint(const QStyleOptionViewItem &option,
                              const QModelIndex &index) const
{
    QVariant value = index.data(Qt::SizeHintRole);
 
    if (value.isValid())
        return qvariant_cast<QSize>(value);
    QRect decorationRect = rect(option, index, Qt::DecorationRole);
    QRect displayRect = rect(option, index, Qt::DisplayRole);
    QRect checkRect = rect(option, index, Qt::CheckStateRole);
    doLayout(option, &checkRect, &decorationRect, &displayRect, true);
    return (decorationRect|displayRect|checkRect).size();
}

QSize QItemDelegate::sizeHint(const QStyleOptionViewItem &option,
                              const QModelIndex &index) const
{
    QVariant value = index.data(Qt::SizeHintRole);

    if (value.isValid())
        return qvariant_cast<QSize>(value);
    QRect decorationRect = rect(option, index, Qt::DecorationRole);
    QRect displayRect = rect(option, index, Qt::DisplayRole);
    QRect checkRect = rect(option, index, Qt::CheckStateRole);
    doLayout(option, &checkRect, &decorationRect, &displayRect, true);
    return (decorationRect|displayRect|checkRect).size();
}

If it returns actual size it should be possible to get the position via loop and sizeHints()
