Adobe Flex Development

Traditional application programmers found it challenging to adapt to the animation metaphor upon which the Flash Platform was originally designed. Flex seeks to minimize this problem by providing a workflow and programming model that is familiar to these developers. MXML, an XML-based markup language, offers a way to build and lay out graphic user interfaces.
Interactivity is achieved through the use of ActionScript, the core language of Flash Player that is based on the ECMAScript standard.

RIAs created with Flex can run in the browser using Adobe Flash Player software or on the desktop on Adobe AIR, the cross-operating system runtime. This enables Flex applications to run consistently across all major browsers and on the desktop. And using AIR, Flex applications can now access local data and system resources on the desktop.

Monochrome have a long history with Flex having been involved with the product since the pre version 1.0 days (then in the form of Prismix), and since then Flex skills have formed an underpinning of our rich internet applications development skillset.

Flex is a free, open source framework for building highly interactive, expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. It provides a modern, standards-based language and programming model that supports common design patterns. MXML, a declarative XML-based language, is used to describe UI layout and behaviours, and ActionScript 3, a powerful object-oriented programming language, is used to create client logic. Flex also includes a rich component library with more than 100 proven, extensible UI components for creating rich Internet applications (RIAs), as well as an interactive Flex application debugger.

The Flex SDK comes with a set of user interface components including buttons, list boxes, trees, data grids, several text controls, and various layout containers. Charts and graphs are available as an add-on. Other features like web services, drag and drop, modal dialogs, animation effects, application states, form validation, and other interactions round out the application framework.


In a multi-tiered model, Flex applications serve as the presentation tier. Unlike page-based HTML applications, Flex applications provide a stateful client where significant changes to the view don't require loading a new page. Similarly, Flex and Flash Player provide many useful ways to send and load data to and from server-side components without requiring the client to reload the view. Though this functionality offered advantages over HTML and JavaScript development in the past, the increased support for XMLHttpRequest in major browsers has made asynchronous data loading a common practice in HTML-based development too.
