        Parameters
        ----------
        app : WX Application, optional.
            Running application to use.  If not given, we probe WX for an
            existing application object, and create a new one if none is found.

        This methods sets the ``PyOS_InputHook`` for wxPython, which allows
        the wxPython to integrate with terminal based applications like
        IPython.

        If ``app`` is not given we probe for an existing one, and return it if
        found.  If no existing app is found, we create an :class:`wx.App` as
