/**
 * \brief Translates SDL events into \c QJoysticks events
 *
 * This class is in charge of managing and operating real joysticks through the
 * SDL API. The implementation procedure is the same for every operating system.
 *
 * The only thing that differs from each operating system is the backup mapping
 * applied in the case that we do not know what mapping to apply to a joystick.
 *
 * \note The joystick values are refreshed every 20 milliseconds through a
 *       simple event loop.
