Detailed Description

A message that invokes a callback method when it gets delivered.

You can use this class to fire off actions that you want to be performed later on the message thread.

To use it, create a subclass of CallbackMessage which implements the messageCallback() method, then call post() to dispatch it. The event thread will then invoke your messageCallback() method later on, and will automatically delete the message object afterwards.

Always create a new instance of a CallbackMessage on the heap, as it will be deleted automatically after the message has been delivered.
