QSettings write and read function

[wysota]

When using ini files, does anyone know how QSettings transforms say a QStringList (or any other object) into the text that is written to the ini file?

Qt is open-source. The easiest way is to look at the code responsible for this.

But since you want to do mangle the data I don't see the point in duplicating what QSettings does for ini files. Just provide your own read and write functions that save to a custom format and do the encryption as part of the process. The simplest possible read/write combination is:

bool readFile(QIODevice &device, QSettings::SettingsMap &map) {
    QDataStream stream(&device);
    device >> map;
    return true;
}
 
bool writeFile(QIODevice &device, const QSettings::SettingsMap &map) {
    QDataStream stream(&device);
    device << map;
    return true;
}

bool readFile(QIODevice &device, QSettings::SettingsMap &map) {
    QDataStream stream(&device);
    device >> map;
    return true;
}

bool writeFile(QIODevice &device, const QSettings::SettingsMap &map) {
    QDataStream stream(&device);
    device << map;
    return true;
}
