The short answer is if you have the time to write the code to use [Bindable(”fooChange”)] the result will be a bit more efficient. Using [Bindable] is easier to write, but has a cost. The cost is roughly what proportion of public properties need to actually dispatch change events. Royale SWCs in Royale releases should never use [Bindable]. We should take the time to optimize and use [Bindable(”fooChange”)]. What the app developer does is their own decision.

In the SDK we can observe different implementations: [Bindable] … public function set foo(value:Boolean):void{ _foo = value; } //----------------------------- [Bindable(”fooChange”)] … public function set foo(value:Boolean):void{ _foo = value; } //----------------------------- [Bindable] … public function set foo(value:Boolean):void{ _foo = value; dispatchEvent(new Event(“fooChange”)); } //----------------------------- [Bindable(”fooChange”)] … public function set foo(value:Boolean):void{ _foo = value; dispatchEvent(new Event(“fooChange”)); } //----------------------------- public function set foo(value:Boolean):void{ _foo = value; dispatchEvent(new Event(“fooChange”)); } What is the difference between these options? In what cases would you implement one or the other? Thx. Hiedra
