Introduction to Flex and Air
Introduction to Flex and Air CS174 Chris Pollett Nov. 24, 2008. Outline • Flash, Flex, and Adobe Air • Installation • Simple Program • Components Flash • Flash was originally a product to make it easy to produce vector based animations on the web created around 1996 based on technology purchased by Macromedia (now Adobe) from Futurewave. • Flash programs are typically executed by the Flash player plug-in which is (Sep 2008) available in some browser on 99% of desktops (Flash >7, for Flash 9 is 98%). • It is used to create Rich Internet Applications (RIA) and competes against AJAX, Silverlight (Windows), Applets (Java), etc. • It can also be used to do tracking (PIE -- Persistent Identification Elements -- not turned off as often as cookies) • It has the advantage over AJAX that as the plug-in is produced by one source, it runs the same in any browser. It also supports richer kinds of media like Video. (YouTube). Flex • The main authoring tool for Flash is Flash Professional, which is GUI IDE designed to make it easy to create Flash. • Flex is an Adobe product which gives a more programmatic way to create Flash files. • There is a Flex IDE, Flex Builder, which can also be used, however, the basic SDK is open sourced under the Mozilla License (can mix proprietary and open source code). • We will only look at the basic SDK which we will access mainly from the command line. • There are other open-source tool chains which can be used to create .swf files, notably, OpenLaszlo. Adobe Air • Air is a product released by Adobe in Feb, 2008 to make it easy to convert Flash programs into stand- alone applications.

This will be a “how- to” chapter: we’ll save diving into the Spark component model until the next chapter (which discusses view states, containers, CSS styling, and skinning). This chapter provides enough examples of using Spark that when it comes time to tackle the theory you’ll have plenty of examples in your head. In four of the five workshop sessions in this chap- ter, we’ll build a fairly small, self-contained Tes- ter.mxml app that has all the code in the example. In session 14, however, I’ll mix things up a little: we’ll build an “Only Connect” game (that bears strong resemblance to a certain trademarked game). We’ll start with a game board that I drew in Adobe Illustrator and saved as FXG. (I’m pro- viding the FXG file I created, so you don’t need to have Adobe Illustra- tor.) We’ll then build a fully functioning game based on this FXG, before 50 SESSION 11 Spark primitives 51 refactoring it and then adding logic for detecting victory.

Graphs in Flash Using the Graph Template Language Himesh Patel, SAS Institute Inc., Cary, NC David Kelley, SAS Institute Inc
Graphs in Flash Using the Graph Template Language Himesh Patel, SAS Institute Inc., Cary, NC David Kelley, SAS Institute Inc., Cary, NC Dan Heath, SAS Institute Inc., Cary, NC ABSTRACT The Graph Template Language (GTL) offers many opportunities for application developers to package simple or complex custom-designed graphs into stand-alone template libraries. In SAS ® 9.2, users can generate static output only through Java rendering. Let’s take a peek into future rendering through the use of Adobe ® Flash. You will be able to use your current GTL code to generate interactive graphs using Flash technology. Once data is visually analyzed, you will be able to publish the graphs in presentations or reports. INTRODUCTION This video poster assumes that users are familiar with the SAS ® Output Delivery System (ODS) and SAS/GRAPH ® software. Because most of the work involves Adobe Flash and Adobe ® Flex ®, it is critical to understand the technology on the surface. Adobe Flash Player is a run-time application that is written in ActionScript, or in the Flex markup language MXML, using Flex SDK. Flex is a collection of technologies that allow developers to develop cross- platform, rich Internet content. Running a Flash application requires a one-time Flash Player download. The Player can be downloaded for free from the Adobe Web site at www.adobe.com . You can define the required content as MXML, which is similar to XML, by creating a new ODS destination using a tagset. One caveat for using this method is that MXML must be compiled into an SWF file before it can be executed by Flash Player.
