QTableWidget sorting

Hello, I am making a QTableWidget which is working nicely. I want the user to be able to sort each column, which is also working, but I don't like how it sorts columns with numbers. It will sort the numbers from 0 to 10 like this:

Quote:

---

0
1
10
2
3
4
5
6
7
8
9

---

But I want it like this:

Quote:

---

0
1
2
3
4
5
6
7
8
9
10

enum Qt::SortOrder just seems to have AscendingOrder and DescendingOrder. Is there anyway to achieve what I want?

Thanks!

Set the data as numbers instead of as text:

Code:

---

int i = 0;
QTableWidgetItem* item = ...
//item->setText(QString::number(i)); // <-- no
item->setData(Qt::DisplayRole, i); // <-- yes

I was facing a similar problem, just a bit more complex than this one.
In a QTableWidget, in some columns I had simple numeric values and in others I wanted to show them with a " %" appended.
e.g. "65.32" -----> "65.32 %"
But when sorting I wanted the cells to be sorted numerically.

Thus I subclassed the QTableWidgetItem and then implemented the "<" operator to sort numbers and not strings.

Code:

---

class MyTableWidgetItem : public QTableWidgetItem
{
	if(text().contains("%"))
	{
		QString str1 = text();
		str1.chop(2);
		QString str2 = other.text();
		str2.chop(2);
		return str1.toDouble() < str2.toDouble();
	}
	else
	{
		return text().toDouble() < other.text().toDouble();
	}
}

Then while populating the table I passed instances of my custom items instead of the generic ones.
I learnt the basics for this technique from here.
