  60   There are 3 menus that have to be rebuilt everytime there are called:
  61   Audio, Video, Navigation

  64   InputAutoMenuBuilder, AudioAutoMenuBuilder, VideoAutoMenuBuilder.

  66   A QSignalMapper decides when to rebuild those menus cf MenuFunc in the .hpp
  67   Just before one of those menus are aboutToShow(), they are rebuild.
