/* The class Core::SystemEventHandler provides a convenient component able to react 
   to system events. Such events are usually generated by the real device the GUI 
   application is designed for. Every time the device notifies the GUI application 
   about a particular event, the corresponding system event handlers are activated. 
   Here for example, the device can report the current status of an engine every 
   time this engine starts or stops. Thereupon the GUI application can react to 
   such event and e.g. update the screen.
   In Embedded Wizard every system event is represented by its own Core::SystemEvent 
   instance. Usually you create and maintain such instances globally, e.g. within 
   a device autoobject. Once a system event instance is available, you can connect 
   a system event handler with it. For this purpose assign the system event instance 
   to the property @Event. Later at the runtime when the system event instance is 
   triggered, all associated system event handlers will be notified causing each 
   handler to send a signal to a slot method stored in its property @OnEvent. In 
   the slot method you are free to implement what to do in response to the event.
   Please note, the delivery of events succeeds asynchronously however always accordingly 
   to the order in which the events were triggered. */
