How many times have you hopped into Flex’s source code only to see the modifier “mx_internal”? No public, private or protected, just mx_internal. It is everywhere in there. But what is it? Turns out, according to Adobe, it is a namespace used to flag functions and properties within the framework that may change in future releases. Obviously, since they might change, Adobe, with all its motherly goodness, hides these properties and functions from us behind this namespace. This does not mean we cannot access them though. We just have to jump through a few small loops. This article will go over how and when to use mx_internal, but also what to be careful about when using them.

Alright designers, lets get one thing straight. I don’t like you and you don’t like me. You design components that are either a)impossible/painstakingly difficult to build or b) has more transitional effects that even make a mac snob would vomit. Dare I complain? Too bad. The client already signed off on it and they loved it. Guess what though, jokes on you! Following my typical fashion, I have made it as easy to style as you have to build it. TAKE THAT EDGY COOL GUY(or girl)!.
Unfortunately, this vicious circle doesn’t help you and it doesn’t help me. You can call me lazy and I can call you a moron but it leads us to the same spot. With this in mind, I’ve recently decided to extend the olive branch. I have sat down with one of the main designers at my job and asked “What can I do to my components that will make your job easier?”. With a warm smile, he thanked me and gave me some good tips on how I can make not just his life easier, but also make my components just that much more versatile.

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.

It can be sometimes difficult to see why someone would want to create an immutable class. We as programmers LOVE to be in control of things, which is what immutable classes limit us to. So what is an immutable class? An immutable class is a object who can not change once it is initialized. All values of that object are fixed and will not change throughout the lifetime of that object. While it may sound like something we dont want, in this article, I will discuss how to make an object immutable and I will also talk about when to use and not use them.
