[docs]class EventGhostEvent(object): """ .. attribute:: string This is the full qualified event string as you see it inside the logger, with the exception that if the payload field (that is explained below) is not None the logger will also show it behind the event string, but this is not a part of the event string we are talking about here. .. attribute:: payload A plugin might publish additional data related to this event. Through payload you can access this data. For example the 'Network Event Receiver' plugin returns also the IP of the client that has generated the event. If there is no data, this field is ``None``. .. attribute:: prefix This is the first part of the event string till the first dot. This normally identifies the source of the event as a short string. .. attribute:: suffix This is the part of the event string behind the first dot. So you could say: event.string = event.prefix + '.' + event.suffix .. attribute:: time The time the event was generated as a floating point number in seconds (as returned by the clock() function of Python's time module). Since most events are processed very quickly, this is most likely nearly the current time. But in some situations it might be more clever to use this time, instead of the current time, since even small differences might matter (for example if you want to determine a double-press). .. attribute:: isEnded This boolean value indicates if the event is an enduring event and is still active. Some plugins (e.g. most of the remote receiver plugins) indicate if a button is pressed longer. As long as the button is pressed, this flag is ``False`` and in the moment the user releases the button the flag turns to ``True``. So you can poll this flag to see, if the button is still pressed.
