flex日志

官方的例子，在debug下运行
package logger
	{ // The empty package. 
    import mx.controls.Button; 
    import flash.events.*; 
    import mx.logging.*; 
    import mx.logging.targets.*; 
        
    public class MyCustomLogger extends Button { 
 
        private var myLogger:ILogger; 
 
        public function MyCustomLogger() { 
            super(); 
            initListeners(); 
            initLogger(); 
        } 
        private function initListeners():void { 
            // Add event listeners life cycle events. 
            addEventListener("preinitialize", logLifeCycleEvent); 
            addEventListener("initialize", logLifeCycleEvent); 
            addEventListener("creationComplete", logLifeCycleEvent); 
            addEventListener("updateComplete", logLifeCycleEvent); 
            
            // Add event listeners for other common events.
