The FlexLib Project

The

FlexLib Project (http://flexlib.googlecode.com/) is an open

source set of containers, controls, and classes to which you are

free to contribute. The FlexLib Project comprises a wide variety

of controls, including a horizontal accordion, advanced sliders

and tab bars, and enhanced tree controls, among others. Fig-

ure 7-5 shows an example of an enhanced tree control showing

some made up sample data.

FlexLib is a must-have for Flex developers. It’s free; it comes

with the source code, so you can see how these things are done;

and it provides a wealth of great controls and classes that you

can use right away.

Alex Uhlmann (http://alex-uhlmann.de/flash/animationpack

age/) has developed a set of distortion effects to supplement

the effects provided in the Flex core. Shown in Figure 7-6 is an

example of the cube blur effect, which allows you to change

Figure 7-5. The enhanced tree control
