TIdIPMCastClient.ThreadedEvent

Description

ThreadedEvent is a Boolean property that indicates if the multicast client should allow use of 
threaded reads from it's listener thread. 
When ThreadEvent is True, the TIdIPMCastListenerThread will use the read method defined in the 
listener thread to trigger the TIdIPMCastClient.OnIPMCastRead event handler. 
When ThreadEvent is False, the read method is synchronized to the main VCL thread.    The default value for ThreadedEvent is DEF_IMP_THREADEDEVENT as assigned in the Create constructor.
