Macro Definition Documentation

#define IMPLEMENT_EVENT_SIGNAL	(		SET,
			FUNCTION,
			QUEUE
	)

Helper macro to implement the various event_signal functions.

Implements two helper functions as documented in the macro.

Parameters

SET	The set in which the event type needs to be eg the gui2::event::tset_event or a similar set defined in that header.
FUNCTION	The function signature to validate the implementation function SFINAE against eg the gui2::event::tsignal_function or another one in that header.
QUEUE	The queue in which the event is slotted.

#define IMPLEMENT_EVENT_SIGNAL_WRAPPER

(

TYPE

)

Value:

IMPLEMENT_EVENT_SIGNAL(tset_event_##TYPE,                                  \
                           tsignal_##TYPE##_function,                          \
                           signal_##TYPE##_queue_)

Small helper macro to wrap IMPLEMENT_EVENT_SIGNAL.

Since the parameters to IMPLEMENT_EVENT_SIGNAL use the same parameters with a slight difference per type this macro wraps the function by its type.

Parameters

TYPE	The type to wrap for IMPLEMENT_EVENT_SIGNAL.
