   * This class changes the default reactor implementation into
   * ACE_QtReactor one by calling TAO_ORB_Core::set_gui_resource_factory.
   * User should create an instance of this class before ORB_init
   * when the TAO server has has to be integrated within Qt event loop.
   *
   * Please notice, this class has to be created in the main Qt thread,
   * because set_gui_resource_factory creates a variable in TSS. This way
   * QtReactor is instantiated only in Qt event loop thread.
