Create a project with a name HelloWorld under a package com.tutorialspoint.client as explained in

the Flex - Create Application chapter.

Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.

Compile and run the application to make sure business logic is working as per the requirements.

Following is the content of the modified mxml file src/com.tutorialspoint/HelloWorld.mxml.

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx"

width="100%" height="100%" minWidth="500" minHeight="500"

initialize="reportEvent(event)"

preinitialize="reportEvent(event)"

creationComplete="reportEvent(event)"

applicationComplete="reportEvent(event)">

<fx:Style source="/com/tutorialspoint/client/Style.css"/>

<fx:Script>

<![CDATA[

import mx.controls.Alert;

import mx.events.FlexEvent;

[Bindable]

private var report:String = "";

private function reportEvent(event:FlexEvent):void{

report += "\n" + (event.type + " event occured at: "

+ getTimer() + " ms" + "\n");

}

]]>

</fx:Script>

<s:BorderContainer width="500" height="500" id="mainContainer"

styleName="container">

<s:VGroup width="100%" height="100%" gap="50"

horizontalAlign="center" verticalAlign="middle">

<s:Label textAlign="center" width="100%" id="lblHeader"

<s:TextArea id="reportText" text="{report}" editable="false"

</s:VGroup>

</s:BorderContainer>

</s:Application>
