37 // Implementation: The concrete EventDescriptor implementation will need to set things up so
38 // some callback (within the EventDescriptor implementation) will be called when the event
39 // happens. This setup happens in 'v_enable()'. This internal handler sets up an EventType
40 // instance if needed and calls 'callback()'.
42 // 'callback()' will access the EventBinding wrapper to find the user-callback to signal. It
43 // will do any needed internal processing, call that user callback and clean up afterwards.
45 /** \brief Generic event interface baseclass
47 The EventDescriptor baseclass provides an interface to manipulate events in a generic
48 way. This allows to register events or to temporarily disable event processing.
