About the Event tag

Use the Event tag to define events that the component emits.

This tag has the following syntax:

[Event("event_name")]

For example, the following code defines a click event:

[Event("click")]

Add the Event statements outside the class definition in the ActionScript file so that the events are bound to the class and not a particular member of the class.

The following example shows the Event metadata for the UIObject class, which handles the resize, move, and draw events:

...
import mx.events.UIEvent;
[Event("resize")]
[Event("move")]
[Event("draw")]
class mx.core.UIObject extends MovieClip {
    ...
}

To broadcast a particular instance, call the dispatchEvent() method. See Using the dispatchEvent() method.
