QSettings - checking the registry hive

[maniek1310]

Hi, using QSettings library, I wrote two functions, viewing and removing the registry keys. Only now I have a problem because I do not know how to modify these functions so that you can remove and check whether there is a branch. example:

We have a branch "HKEY_CLASSES_ROOT\Directory\background\shell\Opróźnij kosz" and now I want to check if the branch "Opróźnij kosz" exists or not, if there is to this branch has been removed.

Function :
@ int Config_os::sprawdz_klucz(QString gdzie, QString key, QString val, QString type)
{
QSettings reg(gdzie, QSettings::NativeFormat);
QString war;

    if(type == "int")
    {
        war = QString::number(reg.value(key).toInt());
    }else if(type == "double")
    {
        war = QString::number(reg.value(key).toDouble());
    }else if(type == "string")
    {
        war = QString(reg.value(key).toString());
    }
 
    if(war == val)
    {
        return 2;
    }else{
        return 4;
    }
 
    return 0;
}
 
int Config_os::usun_klucz(QString gdzie, QString key)
{
    QSettings reg(gdzie, QSettings::NativeFormat);
    QString war;
 
    reg.remove(key);
 
    if(reg.status() == QSettings::NoError)
        return 2;
    else
        return 4;
}
