Examples How to use this example
ActivityEventExample.as
The following example demonstrates the use of the ActivityEvent class by
attaching an event listener method named
activityHandler() to the microphone and
generating text information every time the microphone generates an activity event.
package {
import flash.display.Sprite;
import flash.events.ActivityEvent;
import flash.media.Microphone;
public class ActivityEventExample extends Sprite {
public function ActivityEventExample() {
var mic:Microphone = Microphone.getMicrophone();
mic.addEventListener(ActivityEvent.ACTIVITY, activityHandler);
}
private function activityHandler(event:ActivityEvent):void {
trace("event: " + event);
trace("event.activating: " + event.activating);
}
}
}
