Flex 2 has gone gold

Flex 2 has gone gold for public release: http://www.adobe.com/flex

Tab Navigator Component w/ an integrated tab-close button

First and foremost, I would’ve opened the source on this but because it was for a client of mine, it must stay closed source. But… that doesn’t mean I can’t tell you how I did it.

First off, you might be thinking that you’ll have to override a slew of components to make this work out for you… That is not the case. I managed this by extending the tab navigator component alone. You see, the tab navigator itself is composed of three other readily available components.

Flex 2 Beta 3 : Sprites

In Flex 1.5, typically if we want to add a shape or graphic to the stage, we would make either make a call to createEmptyMovieClip or utilize the MovieClipLoader and add the graphic to the stage. However, in Flex 2 Beta 3, this has changed slightly.

In the Actionscript 3 spec, we’ve been introduced with a new class called the “Sprite” class. A Sprite object is similar to a movie clip, but does not have a timeline. Sprite is an appropriate base class for objects that do not require timelines. For example, Sprite would be a logical base class for user interface (UI) components that typically do not use the timeline.
