I was watching a video about Flex 4 Containers and Layout a few minutes ago and I thought I’d like to post some information about it here.

Did you know…

Spark contains the following Containers:

Non-skinnable containers

• Group
• DataGroup

These containers CAN NOT have visual skins applied to them. Their only purpose is for laying out controls or other containers.

Skinnable containers

• SkinnableContainer
• SkinnableDataContainer
• Panel
• Application

These containers CAN have visual skin applied to them. Their purpose is not only to laying out controls and other containers but also have custom look & feel.

Of these four skinnable containers, only the Panel container have a default visual skin, the other three require that you apply a skin class to them.

That’s all for now but I am planning on posting more about the SkinnableDataContainer and the DataGroup containers. So stay tuned!
