  41    * This class changes the default reactor implementation into
  42    * ACE_QtReactor one by calling TAO_ORB_Core::set_gui_resource_factory.
  43    * User should create an instance of this class before ORB_init
  44    * when the TAO server has has to be integrated within Qt event loop.
  45    *
  46    * Please notice, this class has to be created in the main Qt thread,
  47    * because set_gui_resource_factory creates a variable in TSS. This way
  48    * QtReactor is instantiated only in Qt event loop thread.
