Sorting QStringList using qSort

econtech

Hi,

I am suing QStringList to store the data. QStringList having the following item.
QStringList list<<"user1"<<User2"<<"User7"<<"User10"<<"user6".

I am using qSort() to sort the list as follows.

qSort(list.begin(), list.end(), caseInsensitiveLessThan);

bool caseInsensitiveLessThan(const QString &s1, const QString &s2)
{
return s1.toLower() < s2.toLower();
}

But it give the sortine order as "user1"<<User10"<<"User2"<<"user6"<<"User7".

But i want the following order after sorting.

"user1"<<"User2"<<"user6"<<"User7"<<"User10".

Can any one of you give solution to solve the problem its very helpful.

Thanks in advance

There is no one-liner for that. You need a better comparison function called "natural comparison" i.e. not how a computer understands order but how humans do.

Here's a nice implementation of such algorithm with code for various languages: http://www.davekoelle.com/alphanum.html
You should be able to easily modify it to fit with qSort.
