def OpenUri(self, uri):
self.iface.OpenUri(uri)<EOL>
Opens the Uri given as an argument

        :param str uri: Uri of the track to load.

        Its uri scheme should be an element
        of the org.mpris.MediaPlayer2.SupportedUriSchemes property
        and the mime-type should match one of the elements
        of the org.mpris.MediaPlayer2.SupportedMimeTypes.

        If the playback is stopped, starts playing
        If the uri scheme or the mime-type of the uri to open is not supported,
        this method does nothing and may raise an error.
