def enable(self, app=None):
        """DEPRECATED since IPython 5.0

        Enable event loop integration with PyGTK.

        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 PyGTK, which allows
        the PyGTK to integrate with terminal based applications like
        IPython.
