Video: Simple Container Effects: The Sequel!

Simple Container Effects, Part 2, the next episode in the gripping and suspenseful series CodeDependent, is now available from Adobe TV.

This episode is the sequel to last week's cruel joke that showed how to animate adding and removing items to/from a VBox ... sorta. It turns out that the automatic gap that VBox adds for new items, or removes for deleted items, causes a jarring snap that makes the approach in last week's show less than perfect. It worked okay, but we can do better.

This week's episode shows a completely different approach to solving the problem via state transitions. In this case, we're not actually changing states in the application. But that doesn't mean we can't use the mechanism of state transitions to help automate these effects.

Note that this is a Flex 3 app. I've been talking about Flex 4 a lot these days (it's kinda on my mind recently, given where we're at with that product), but there's a lot of cool stuff you can do with Flex 3 effects as well. This example, like last week's, is all Flex 3.
