Sort filenames naturally with Qt

If you want to use QCollator to sort entries from the list of entries returned by QDir::entryList, you can sort the result with std::sort():

dir.setFilter(QDir::Files | QDir::NoSymLinks);
dir.setSorting(QDir::NoSort);  // will sort manually with std::sort

auto entryList = dir.entryList();

QCollator collator;

    [&](const QString &file1, const QString &file2)
        return, file2) < 0;

According to The Badger‘s comment, QCollator can also be used directly as an argument to std::sort, replacing the lambda, so the call to std::sort becomes:

std::sort(entryList.begin(), entryList.end(), collator);
