def Quit(self):
self.iface.Quit()<EOL>
Causes the media player to stop running.
        The media player may refuse to allow clients to shut it down.
        In this case, the CanQuit property is false
        and this method does nothing.
        Note: Media players which can be D-Bus activated,
        or for which there is no sensibly easy way to terminate
        a running instance (via the main interface or a notification area icon
        for example) should allow clients to use this method.
        Otherwise, it should not be needed.
        If the media player does not have a UI, this should be implemented.
