Excerpt:
One of the great things about I love about Flex is that it is fairly close to writing a desktop application. You can, for the most part, even take a Flex application and publish it as an AIR application for your desktop. In my opinion, one thing that makes it extremely similar is the way it handles Events. Its all about the eventListeners. As we all know, it is never as easy as adding an eventListener in one spot and a eventHandler in another. Within this article, I want to discuss how to add and handle eventListeners, dispatching them, how to stop event from propagating, difference between a target and a currenttarget, and the ever important thought of when to remove events.
