Example 1 with ControllerEvent

use of com.codename1.rad.controllers.ControllerEvent in project CodeRAD by shannah.

the class ActionSupport method dispatchEvent.

 * if it implements EventProducer interface.  If event not consumed,
 * it will find the nearest ViewController and dispatch the event
 * up the controller chain. Latter also requires that event is ControllerEvent
