|phoenix_title|  **wx.lib.pubsub.core.datamsg.Message**
==========================================================================================================================================

A simple container object for the two components of a message in the
arg1 messaging protocol: the
topic and the user data. Each listener called by sendMessage(topic, data)
gets an instance of Message. The given 'data' is accessed
via Message.data, while the topic name is available in Message.topic::

    def listener(msg):
        print("data is %s" % msg.data)
        print("topic name is %s" % msg.topic)
        print(msg)

The example also shows (last line) how a message is convertible to a string.
