A couple of months ago, someone asked on my blog how they could run simple effects on a container like VBox when adding or removing items. So I took a run at it and came up with this example. It's not that complicated - you basically create a Sequence effect that resizes the object in question and fades it in/out (based on whether it's coming or going).
It's also not a perfect solution: run the demo and you'll see a [snap] at the beginning of the adding effect or the end of the removing effect. It's not that bad, but maybe we can do better. And we will in Part 2, next week... (whoa, talk about cliff-hangers!)
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 is all Flex 3.
Here's the video:
Here is the demo application:
