Hmmm... What I do is to create a Python class with the settings as member
variables. That makes it easier. But still, the Qt documentation says:

 A typical usage pattern for application exit or 'save preferences': 

    QSettings settings;
    settings.insertSearchPath( QSettings::Windows, "/MyCompany" );
    // No search path needed for Unix; see notes further on.
    settings.writeEntry( "/MyApplication/background color", bgColor );
    settings.writeEntry( "/MyApplication/geometry/width", width );
    // ...

So, depending on the destructor is not the only way to go.
