Flex event Mechanism 2: Custom events

In addition to using events in ActionScript, flex also allows developers to customize events. A typical Custom Event inherits the Flash. Events. event class and declares multiple event names. As follows:

Package test. Events
... {
Import flash. Events. event;

Public   Class Myevent extends event
... {
Public Function myevent (type: String, bubbles: Boolean =   False , Cancelable: Boolean =   False ) ... {
Super (type, Bubbles, cancelable );
}

Public   Static   Const Event_a: String =   " Event_a " ;
Public   Static   Const Event_ B: String =   " Event_ B " ;
}
}
