As3-Signals is a new approach for AS3 events, inspired by C# events and signals/slots in Qt. Signals are light-weight, strongly-typed AS3 messaging tools. The main idea is:

  • A Signal is essentially a mini-dispatcher specific to one event, with its own array of listeners;
  • A Signal gives an event a concrete membership in a class;
  • Listeners subscribe to real objects, not to string-based channels;
  • Event string constants are no longer needed;
  • Signals are inspired by C# events and signals/slots in Qt.


// with EventDispatcher
button.addEventListener(MouseEvent.CLICK, onClick);

// Signal equivalent; past tense is recommended
