Cairngorm Series

MVC Flex applications using Cairngorm

This series caters to individuals who are brand-spanking new to Cairngorm. What is Cairngorm? It’s an MVC framework for Flex: a library of ActionScript classes available for download at Adobe Labs that can help make writing Flex applications easier. Not necessarily faster. But easier, and in my opinion, more enjoyable.

Until all the videos are done for Part One, here are the files from my presentation on 3/11/2008 including the slot machine demo.

Part One: Fundamentals

In the first series of posts we will construct an extremely simple application which consists of a Button and a Label. When the button is clicked we need to increment a Number and display the new value in the label. Let’s get started.

  1. Moving towards MVC without Cairngorm.
       - All future entries utilize the Cairngorm framework
  2. The ModelLocator holds application data.
  3. Create a View and bind to application data.
  4. The View dispatches a CairngormEvent.
  5. The FrontController listens.
  6. The FrontController executes a Command.
  7. It works! Let’s do it better with Value Objects and Model Objects.
  8. Tip one: Always pass targets to Commands.
  9. Tip two: Make the View as stupid as possible.
  10. Tip three: Make the View as reusable as possible.
