QVariant

[durus90]

Hello every1!

I have this code:

class Model
{
public:
    Model(const QString& path);
    double getVehicleWeight()
    {
        m_settings->beginGroup("vehicle");
        const QStringList childKeys = m_settings->childKeys();
        foreach (const QString &childKey, childKeys)
          {
              //Here I want to return a double using QVariant, each line of my config file have (ex: weight = 60)
          }
        m_settings->endGroup();
    }
private:
    void initSettings(const QString& path);
protected:
    std::unique_ptr<QSettings> m_settings;
};
 
Model::Model(const QString& path)
{
   initSettings(path);
}
 
void Model::initSettings(const QString& path)
{
    m_settings = std::make_unique<QSettings>(path, QSettings::IniFormat);
}
 
int main()
{
    Model obj("/d/users/F27279C/Desktop/TESTINI/TestINI/New folder");
    qDebug() << "PLS WORK!";
    obj.getVehicleWeight();
}

class Model
{
public:
    Model(const QString& path);
    double getVehicleWeight()
    {
        m_settings->beginGroup("vehicle");
        const QStringList childKeys = m_settings->childKeys();
        foreach (const QString &childKey, childKeys)
          {
              //Here I want to return a double using QVariant, each line of my config file have (ex: weight = 60)
          }
        m_settings->endGroup();
    }
private:
    void initSettings(const QString& path);
protected:
    std::unique_ptr<QSettings> m_settings;
};

Model::Model(const QString& path)
{
   initSettings(path);
}

void Model::initSettings(const QString& path)
{
    m_settings = std::make_unique<QSettings>(path, QSettings::IniFormat);
}

int main()
{
    Model obj("/d/users/F27279C/Desktop/TESTINI/TestINI/New folder");
    qDebug() << "PLS WORK!";
    obj.getVehicleWeight();
}

I know the ,,foreach" will go through all my document, but i dont want that
I want ot make a getter for every line of my config file which will return the value from it
All the values are double
so what I ask is:
- how can I access a specific line of my config for ex weight or speed?
- how can I return a double using QVariant?

thx for help!
