Trouble with sortItems coercion of text in QTableWidget

[Lykurg]

if (val <= "0")

if (val <= "0")

To copy to clipboard, switch view to plain text mode 

I would leave the quotation marks since you want compare the value numerical. Therefore also see toDouble().

itemReplace = new QTableWidgetItem("0.0001");
                ui->timing_tableWidget->setItem(i, j, itemReplace);

itemReplace = new QTableWidgetItem("0.0001");
                ui->timing_tableWidget->setItem(i, j, itemReplace);

There is no need to create a new item! just use your variable item and set the new text there.


See if that solves your problem.


EDIT: instead of test all the cells you could use QTableWidget::itemChanged() to only check a changed item.
