4.3.16 MSceneMessage

The following MSceneMessage methods differ from their C++ counterparts.

addCallback( msg, func, clientData=None, status=None)
This method wraps the version that registers a callback that has the option to abort the operation. The callback func only takes the client data as input and has to return a bool. You may also return nothing at all which actually returns the value None which is interpreted as False. So similar to the C++ version you can either register a callback that does not return any value or that returns a boolean. However, in both cases the wrapper uses the same C++ version of addCallback().
