QSettings HKEY_CLASSES_ROOT access

[Arsenic]

I was wondering if it was possible with Qt to access HKEY_CLASSES_ROOT

like so:

QSettings settings;
if(settings.value("HKEY_CLASSES_ROOT\\Cool\\Shell\\open\\ddeexec\\Topic", QString("")) == QString("")){
      settings.setValue("HKEY_CLASSES_ROOT\\Cool", "AValue");
      // more registry values.
}

QSettings settings;
if(settings.value("HKEY_CLASSES_ROOT\\Cool\\Shell\\open\\ddeexec\\Topic", QString("")) == QString("")){
      settings.setValue("HKEY_CLASSES_ROOT\\Cool", "AValue");
      // more registry values.
}

To copy to clipboard, switch view to plain text mode 

I wasn't able to get it to work, and if someone can show me a way it would be great, because I tried to read through the Settings docs for hours...

Thanks,.
