If the constructor is private, you can accomplish this task via:

class SettingsPrivate;
class Settings: public ...
{
public:
    [....]
    static Settings *self();
private:
    Settings(const QString &);
    ~Settings();
    friend class SettingsPrivate;
};


class SettingsPrivate
{
    Settings q_ptr;
    [... other privates ...]
};
K_GLOBAL_STATIC(SettingsPrivate, s_self)

Settings *Settings::self()
{
    return &s_self->q_ptr;
}
