Flex can’t do it all alone. While it’s possible to build a RIA in strictly ActionScript 3.0 or Flex 3’s MXML, sometimes you have to be familiar with both methods to get the best result.
In this post we’ll look at two ways of making one of the most common components in Flash and Flex development: the label.
Flex makes actionscript less of a chore and more of a design asset. One of the best demonstrations of this is the simplicity of charting with MXML.
In this tutorial we’ll take test scores from XML files and make a dynamic bar graph out of the results in no time at all. You’ll have impressed yourself by the end.
Flash Catalyst looks good. Not enough enthusiasm for you? Try absolutely fantastic! Skinning Flash and Flex apps have gotten easier over the years, they still haven’t reached the point where it actually feels right.
With the newly introduced Flash Catalyst, these design headaches look like they’ll soon be a thing of the past.
If you’re still using arrays and text files to load content, it’s time to upgrade.
With XML, you can condense a whole mess of seemingly unrelated information into a well organized and easy to read file. Today we’ll be looking at how to take advantage of this with Flex 3. This tutorial will teach how to load an external XML file into Flex and then filter the results into labels.
It sounds a lot like a buzzword for developers, but what is data binding exactly? Is it even useful? In short, absolutely. Chances are you’ll be working with some sort of data in Flex. With data bindings, a developer can link data automatically between sources and targets. Still confused? Imagine a label set to automatically display the value of a selected button. It’s a simple concept that has an incredible amount of usefulness when building RIA’s. On second thought, let’s just build it.
