QTableWidget test if the cell or item are empty

[jpn]

There are no items in cells until one sets them with QTableWidget::setItem() or after user has edited them.

QTableWidgetItem* item = tableWidget->item(0,0);
if (!item || item->text().isEmpty())
{
   ...
}

QTableWidgetItem* item = tableWidget->item(0,0);
if (!item || item->text().isEmpty())
{
   ...
}

To copy to clipboard, switch view to plain text mode
