Example Code for 360Flex Apollo Session

During my Apollo overview session at 360Flex, I built a simple HTML editor that provided live preview and allowed the HTML to save to the desktop. It is a pretty simple app, but it shows an example of using both the File API in Apollo as well as HTML.

I mentioned in the session that I would post it online, so here it is:

PRE {font : normal normal normal 12 “Courier New”, Courier, Arial;;}

<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"><mx:Script><![CDATA[import flash.filesystem.FileMode;import flash.filesystem.FileStream;import flash.filesystem.File;/* Called when the user wants to save the file */private function onSave():void{//Get a reference to the desktop        var desktop:File = File.desktopDirectory;//create a reference to the file on the desktop in which we will save html        var saveFile:File = desktop.resolve(fileName.text);//create a FileStream instance to write to the file        var fs:FileStream = new FileStream();//open file in WRITE mode        fs.open(saveFile, FileMode.WRITE);//write the string to the file        fs.writeUTFBytes(input.text);//close the file / file stream        fs.close();}/* called when text in the TextArea changes */private function onTextChange():void{//pretty simple. Copy text from TextArea into HTML control as HTML        html.htmlText = input.text;}]]></mx:Script><!-- Used to enter HTML --><mx:TextArea right="0" left="0" id="input" top="0" height="139" textInput="onTextChange()"/><!-- Save Button --><mx:Button label="Save" id="saveButton" bottom="10" right="10" click="onSave()"/><!-- File Name on Desktop to save HTML in --><mx:TextInput id="fileName" right="72" bottom="10" text="test.html" /><!-- HTML field to do live preview of HTML --><mx:HTML right="0" left="0" top="147" bottom="40" id="html"/></mx:Application>
