Sorting elements in QTableWidget

[Elmo23x]

Hi to all!

I want to sort some elements in a QTableWidget.... the problem is that I do not know how to do it with a colum with numbers in a correct way. Now the result is something like this:

1
10
11
12
2
20
21
3
4
5
6

and I would like to have:

1
2
3
4
5
6
10
11
12
20
21


I hope that you can understand what I mean Thanks for your help!!!

Either set the numbers as integers, not as text or provide a custom QTableWidgetItem::operator<().


Approach 1:

int i = 0;
QTableWidgetItem* item = ...;
item->setText(QString::number(i)); // don't use this
item->setData(Qt::DisplayRole, i); // but this

int i = 0;
QTableWidgetItem* item = ...;
item->setText(QString::number(i)); // don't use this
item->setData(Qt::DisplayRole, i); // but this

To copy to clipboard, switch view to plain text mode 

Approach 2:
Subclass QTableWidgetItem, override QTableWidgetItem::operator<().

void sortAsc()
			{
			TableWidget->sortItems ( TableWidget->currentColumn() ,  Qt::AscendingOrder );
			}
			void sortDesc()
 
			{
				TableWidget->sortItems ( TableWidget->currentColumn() ,   Qt::DescendingOrder );
			}

void sortAsc()
			{
			TableWidget->sortItems ( TableWidget->currentColumn() ,  Qt::AscendingOrder );
			}
			void sortDesc()

			{
				TableWidget->sortItems ( TableWidget->currentColumn() ,   Qt::DescendingOrder );
			}

This does not make any difference because the items are in ascending order. They just need to be interpreted and sorted as numbers, not as text.
