can't load properties from a class using qsettings

[AndreAhmed]

I'm trying to save and load a class using the following functions in Qt

void EraObject::staticLoadFrom(Settings &set, QObject *object, const bool &ownGroup)
{
    Q_ASSERT(object);
    bool modified;
    const QMetaObject *superMeta = object->metaObject()->superClass();
    const QMetaObject *meta = object->metaObject();

    const QString &group = object->objectName().isEmpty() ? meta->className() : object->objectName();

    if (ownGroup)
        set.beginGroup(group);

    qCDebug(loadLog) << group;

    for (int i = superMeta->propertyOffset(); i < meta->propertyCount(); i++) {
        modified = false;
        const QMetaProperty &prop = meta->property(i);
        QMetaType::Type type = (QMetaType::Type)prop.type();

        if (prop.isUser()) {
            switch (type) {
            case QMetaType::QDateTime:
                modified = setOrReset(set, object, prop, QDateTime::fromString(set.value(prop.name(), "").toString(), "yyyyMMddhhmmsszzz"));
                break;
            case QMetaType::QString: {  //check if there is an localized string first (eg.: name@de=test)
                const QVariant value = set.value(QString("%1@%2").arg(prop.name()).arg(QLocale::system().bcp47Name()),
                                                 set.value(prop.name(), ""));
                modified = setOrReset(set, object, prop, value);
                break;
            }
            case QVariant::UserType: {
                QObject *obj = prop.read(object).value<QObject *>();
                Q_ASSERT_X(obj, "staticLoadFrom", "Custom class NOT known to QMetaType, register it with qmlRegisterType()!");

                bool check = QMetaObject::invokeMethod(obj,
                                                       "loadFrom",
                                                       Qt::DirectConnection,
                                                       Q_ARG(Settings &, set));    //we invoke cause it can be just QObject(e.g. QAbstractItemModel)
                Q_ASSERT_X(check, "staticLoadFrom", "Could not invoke. Be sure you subclassed EraObject or defined method!: " + obj->objectName().toLatin1());
                break;
            }
            default:
                modified = setOrReset(set, object, prop, set.value(prop.name(), ""));
            }

            qCDebug(loadLog) << "modified:" << modified << "Property:" << prop.name();
        }
    }
    if (ownGroup)
        set.endGroup();
    object->setProperty("dirty", NotDirty);
}

void EraObject::staticSaveTo(Settings &set, QObject *object, const bool &ownGroup, const bool &force)
{
    Q_ASSERT(object);
    if (force || object->property("dirty").toInt() == RamDirty) {
        const QMetaObject *superMeta = object->metaObject()->superClass();
        const QMetaObject *meta = object->metaObject();

        const QString &group = object->objectName().isEmpty() ? meta->className() : object->objectName();

        if (ownGroup)
            set.beginGroup(group);

        qCDebug(saveLog) << group;

        for (int i = superMeta->propertyOffset(); i < meta->propertyCount(); i++) {
            const QMetaProperty &prop = meta->property(i);
            if (prop.isUser()) {
                QMetaType::Type type = (QMetaType::Type)prop.type();
                switch (type) {
                case QMetaType::QDateTime:
                    set.setValue(prop.name(), prop.read(object).toDateTime().toString("yyyyMMddhhmmsszzz"));
                    break;
                case QMetaType::Float:
                case QMetaType::Double:
                    set.setValue(prop.name(), QString::number(prop.read(object).toDouble(), 'g', MAX_SAVED_DECIMALS));
                    break;
                case QMetaType::User: {
                    QObject *obj = prop.read(object).value<QObject *>();
                    Q_ASSERT_X(obj, "staticLoadFrom", "Custom class NOT known to QMetaType, register it with qmlRegisterType()!");

                    bool check = QMetaObject::invokeMethod(obj,
                                                           "saveTo",
                                                           Qt::DirectConnection,
                                                           Q_ARG(Settings &, set),
                                                           Q_ARG(bool, true),
                                                           Q_ARG(bool, force));
                    Q_ASSERT_X(check, "saveTo", "Could not invoke. Be sure you subclassed EraObject or defined method!: " + obj->objectName().toLatin1());
                    break;
                }
                default:
                    if (!prop.isConstant())
                        set.setValue(prop.name(), prop.read(object));
                }
            }
        }
        if (ownGroup)
            set.endGroup();
        object->setProperty("dirty", NotDirty);
        set.sync();
    }
}
Now I try to save and load the class using the following methods

void Method::loadFrom(Settings &set, bool ownGroup)
{
    Settings s("profiles.ini");
    s.beginGroup("Profiles");
   // s.beginGroup(m_filename);
    foreach (const QString &group, s.childGroups()) {
        if(group == " Default")
            continue;
        s.beginGroup(group);
        Profile *profile = new Profile();
        profile->setObjectName(group);
        profile->loadFrom(s);
        s.endGroup();

        m_currentProfile->m_Profiles << profile;
    }
    s.endGroup();

    EraObject::staticLoadFrom(set, this, ownGroup);

}

void Method::saveTo(Settings &set, bool ownGroup, bool force)
{
    Settings s("profiles.ini");
    s.beginGroup("Profiles");
    //s.beginGroup(m_filename);
    foreach(Profile * profile, m_currentProfile->m_Profiles) {
      //  s.beginGroup(profile->profilename());
        profile->saveTo(s);
       // s.endGroup();
    }
    s.endGroup();
    s.sync();

    EraObject::staticSaveTo(set, this, ownGroup, force);

}

The class can be saved correctly and that's the result in the ini file

[Profiles]
jjk\Ta=20
jjk\Te=48
jjk\Texp=38
jjk\lim1=0
jjk\lim2=0
jjk\offset=0
jjk\profilename=jjk
tyy\Ta=20
tyy\Te=48
tyy\Texp=38
tyy\lim1=0
tyy\lim2=0
tyy\offset=0
tyy\profilename=tyy

The problem is the loaded values are all zeros and it doesn't load Ta, Te, Texp..etc.

I don't know where is the problem.

Hi,

Might be a silly question but are you sure you are entering loadFrom and the loop in it ?
