Save and read enum by QSettings

[sonichy]

*.h
{
private:
    enum {
        TEXT_CLOCK,
        DIGITAL_CLOCK,
        ANALOG_CLOCK
    } clock_type;
}

*.cpp
{
    QSettings settings(QCoreApplication::organizationName(), QCoreApplication::applicationName());
    clock_type = settings.value("ClockType");
    if (clock_type == NULL)
        clock_type = TEXT_CLOCK;
    QAction *action_text = new QAction("Text", this);
    connect(action_text, &QAction::triggered, [=](){
        clock_type = TEXT_CLOCK;
        settings.setValue("ClockType", clock_type);
    });
    addAction(action_text);
}

Is it so hard to write down what your problem is instead simply posting a code snippet?

@sonichy you did not specify a type for your enum, so it's an normal int (int32_t) simply cast it to and from the enum type.

@sonichy said in Save and read enum by QSettings:

clock_type = settings.value("ClockType");
if (clock_type == NULL)

If you look at the docs for QSettings::value() you will see that it returns a QVariant.
So such a check doesnt make much sense.

enum ClockType {
        TEXT_CLOCK,
        DIGITAL_CLOCK,
        ANALOG_CLOCK
};
ClockType clockType;

settings.setValue("ClockType", clockType); //save
clockType = static_cast<ClockType>(settings.value("ClockType").toInt()); //read
