          Parameters
          ----------
          app : ignored
             Ignored, it's only a placeholder to keep the call signature of all
             gui activation methods consistent, which simplifies the logic of
             supporting magics.
  
          Notes
          -----
          This methods sets the ``PyOS_InputHook`` for pyglet, which allows
          pyglet to integrate with terminal based applications like
          IPython.
