Read a text file line by line in Qt

Question

How can I read a text file line by line in Qt?

I'm looking for the Qt equivalent to:

std::ifstream infile; std::string line; while (std::getline(infile, line)) {    ... }

Use this code:

QFile inputFile(fileName); if (inputFile.open(QIODevice::ReadOnly)) {    QTextStream in(&inputFile);    while (!in.atEnd())    {       QString line = in.readLine();       ...    }    inputFile.close(); }
