    # notifies others that the engine is ready.

    # Do this if you need to see the MayaVi tree view UI.
    ev = EngineView(engine=e)
    ui = ev.edit_traits()

    # Create a new scene.
    scene = e.new_scene()
    # Now create a new scene just for kicks.
    scene1 = e.new_scene()

    # Now setup a normal MayaVi pipeline.
    src = VTKXMLFileReader()
    return e, ui

if __name__ == '__main__':
    # When main returns the ui to go out of scope and be gc'd causing the view
    # to disappear with qt4.
    e, ui = main()
    # Create a GUI instance and start the event loop.  We do this here so that
    # main can be run from IPython -wthread if needed.
    gui = GUI()
