error: ‘QFile::QFile(const QFile&)’ is private by using a foreach

[ChrisW67]

The error message is self explanatory. You cannot copy a QFile (or any other QObject), and the copy constructor has been made private to enforce this. foreach() will be implicitly converting each string in your list to a QFile in a way that tries to invoke the copy constructor, e.g.

QFile foundFile = QString("test");

QFile foundFile = QString("test");

Your loop needs to be:

foreach(const QString &name, files) {
    QFile foundFile(name);
    // operations...
}

foreach(const QString &name, files) {
    QFile foundFile(name);
    // operations...
}
