Re: Sort numerically QTableWidget

Hi,
The easiest and proper solution is to set the data as integers, not as text:
QTableWidgetItem* item = ...
item->setText("2"); // not like this
item->setData(Qt::DisplayRole, 2); // but like this
The sorting will work correctly out of the box. Also, editable items
have spin boxes instead of line edits as editors.
Another solution (or more like a workaround) is to inherit
QTableWidgetItem and reimplement QTableWidgetItem::operator<().
