How to disable QTableWidget scrolling to selected cell?

问题

Currently, if the user clicks on a cell that is only partially visible, the window automatically scrolls over so that the cell is fully displayed. Is there any way to stop the table doing this? Thanks

回答1:

The scrolling is done by QAbstractItemView which call the virtual function scrollTo with index the hint EnsureVisible. You can't prevent the call, because it is done through a private timer, but you can change what the scrollTo function does:

void TableWidget::scrollTo(const QModelIndex &index, ScrollHint hint)
{
    if(hint == QAbstractItemView::EnsureVisible)
        return;
    QTableWidget::scrollTo(index, hint);
}

And to still be able to scroll to an item manually, you could write another member function that would call QTableWidget::scrollTo.

You can easily disable this behavior with:

ui->tableWidget->setAutoScroll(false);

alexisdm's answer is dealing with another problem. Suppose you are incrementally appending new rows to your table and you want to maintain current vertical scroll position. I am dealing with this second problem and alexisdm's answer seems promising.
