The Flex 4 learning curve will be from Spark and its new skin programming model. Here is another source to learn a few things from, Christonphoe Coenraets’s post Creating a Custom Component and Skins in Flex 4.
Coenraets created webcam app that takes pictures and display them. He skinned the application differently while maintaining the same code base for app logic.
I noticed a few things though. One, he used Skin class as the base class for the skin class. Most of the documents and apps use SparkSkin. Does this matter? Or, is there any reason he didn’t use SparkSkin.
Also, there are some code written in the 2nd skin class. If truly separates the roles of designing and coding an application, can that code be moved to the host component? Or does it have to be in the skin class?
