Dispatching an event

You use the dispatchEvent() method to dispatch an event. The dispatchEvent() method has the following signature:

public dispatchEvent(event:Event):Boolean

This method requires an argument of type Event, which is the event object. The dispatchEvent() method initializes the target property of the event object with a reference to the component dispatching the event.

You can create an event object and dispatch the event in a single statement, as the following example shows:

dispatchEvent(new Event("click")); 

You can also create an event object, initialize it, and then dispatch it, as the following example shows:

var eventObj:EnableChangedEvent = new EnableChangedEvent("enableChanged");
eventObj.isEnabled=true;
dispatchEvent(eventObj);

For complete examples that create and dispatch custom events, see Creating Advanced MXML Components and Creating Simple Visual Components in ActionScript.
