setMessageListenerBySelector function


void QAManagerBase::setMessageListenerBySelector(
qa_const_string address,
qa_const_string selector,
QAMessageListener * listener


Sets a message listener class to receive QAnywhere messages asynchronously, with a message selector.

The listener is an instance of a class implementing QAMessageListeneronMessage, the only method defined in the QAMessageListener interface. QAMessageListeneronMessage accepts a single QAMessage parameter.

The setMessageListener address parameter specifies a local queue name used to receive the message. You can only have one listener assigned to a given queue. The selector parameter specifies a selector to be used to filter the messages to be received on the given address.

If you want to listen for QAnywhere system messages, including push notifications and network status changes, specify "system" as the queue name. Use this method to receive message asynchronously.
