Is there an easier way to build and deliver rich internet applications (RIAs) other than the Flash IDE or Ajax? Absolutely. With Adobe Flex 2, the Flex 2 SDK, and this book, you have all you need to build RIAs. Programming Flex 2 offers you plenty of practical and useful examples that reveal how and why to use a particular feature of Flex 2, and when and when not to. As part of the Adobe Developer Library, Programming Flex 2 is the authoritative guide to this new Adobe framework. You learn to use a markup language called MXML and a vast library of off-the-shelf and highly-configurable components to build Flash-based applications that combine the immediacy of the Web with the functionality and responsiveness of desktop applications. You also discover why -- with the Flash Player runtime environment and the powerful ActionScript 3.0 programming language -- the possibilities with Flex 2 are nearly limitless. Topics include: Managing Layout Working with Components Working with Media Managing State Using Transitions and Effects Working with Data Customizing Application Appearance Client Data Communication and Remote Data Communication Debugging Flex Framework Applications Creating Custom Components Flex may be easier to learn than the Flash IDE, but you still need a reliable guide to the framework. Programming Flex 2 not only serves as a reference, but provides valuable and practical insight into this new technology. As you learn how to build Flex applications, you'll also discover how Flex works. This book supplies all the information you need in one convenient place.
