QFile::readAll()
returns a byte array which contains each and every byte of the file as a separate element.
For your use case, you need to read the file line by line.
The QFile documentation shows some approaches how to do this, for example:
QVector<int> elements;
QFile sequence("Sequences.dat");
if (!sequence.open(QIODevice::ReadOnly | QIODevice::Text))
return;
QTextStream in(&sequence);
while (!in.atEnd()) {
QString line = in.readLine();
elements.append(line.toInt());
}
Despite the fact that this sample is from the Qt documentation, I would recommend to check the return value from in.readLine()
which returns a null QString
when the end of the file has been reached, instead of using atEnd()
.
