Flex Components – Visualization Explorer by Ben Stucki

Ben Stucki created a great visualization component for Flex 2. He recently published the component into the new Adobe Flex Exchange. The visualizer takes data from a sound object and renders it to screen with support for filters.

Starting next week I will be posting some very detailed information on creating components for Flex 2 and announcing Adobe’s efforts in creating a component marketplace. If you are creating components for Flex 2, drop me a note at tpatrick(A)

Great work Ben!

LiveDocs – Flex 2 Language Reference

The Flex documentation team has outdone themselves with the livedocs language reference for Flex 2. It is easily one of the best resources for Flex development and is always open on my desktop during development.

I encourage you to improve the documentation and post your comments. Comments give the documentation context and help flag common development issues.

FLEX.ORG – The Directory for Flex

Today the Flex team launched Flex to establish single site to provide a directory to the world of Flex. We will be adding features to accelerate Flex adoption, enable developers, and document the best resources both within the community and at Adobe.

I look forward to working with you on making a world class resource for Flex developers. Today we begin this journey with a simple site but things will change rapidly.

Player 9 Released – This changes everything!

I have watched the release of 7 versions of Flash Players but somehow Player 9 is a wildly different release. This release adds AS3 support, a JIT compiler, and a wildly improved AS3 API. FP9 is very advanced and yet remains smaller than 1.2MB.

Making things fast and small is not very easy. To think that Flash Player 9 includes a JIT compiler that emits X86 and PPC native machine code from AS3 bytecode is simply incredible. It is a true accomplishment for the Flash Player Engineering Team at Adobe and will revolutionize applications and the Internet.

I believe this release is a change in direction for Flash Player. It is a sneak attack as it arms the innocent graphical Flash Player with a real class based programming language capable amazing things. Combined with rich vector graphics and pixel perfect text, we will see a new class of application emerge.

Better still is the effect that Flash Player 9 will have on Apollo. As one of the primary engines in Apollo, Flash Player 9 enables a new class of Rich Desktop Applications that merge the best of the Internet and the Desktop.

Wow, exciting times ahead.

Flex Extensibility – Blink for Flex

It seems that many developers do not realize that Flex is extensible. Sure its XML, but Flex allows you to create new components and extend MXML in your applications. To make this point clear I wrote the dreaded Blink tag for Flex.

Blink Tag for Flex 2 (View Source Enabled)

Blink Tag Source(ZIP)

HTML and its success has always been tightly bound to a browser HTML/JavaScript version. Each browser embeds its logic for interpreting HTML and JS within each 5MB-30MB Download of Internet Explorer and Firefox. The only way to upgrade this logic today is to download a new browser.

With Flash Player, the browser and os are completely independent resulting in the ability to run new Flash Players and applications (Flex, Flash, Breeze) in older browsers and operating systems.


– Go find an old copy of Netscape 3.0
– Install Flash Player 9
– Build a Flex 2 application and it will work seamlessly!

Given that Flash player is upgradable with a 1MB download, long term Flash Player will be more compatible than the base browser for building applications. The result is a wide compatibility footprint for Flash Player for delivery of applications.

In supporting components within the Flash Player, Adobe decided to deliver component to the Flash Player within the SWF and RSL formats. Basically, components are delivered with your application, they never ship in the Flash Player. This keeps the player very small and allows developers to creatively extend applications using ActionScript and all formats supported by Flash Player (SWF, GIF, JPG, PNG, FLV, XML, AMF, MP3, and others).

In Flex development you can write a new ActionScript Class and extend MXML and the applications you are creating. In writing the Blink Tag, I simply extended the mx.controls.Text component like so:

package com.ted.text{

    import mx.controls.Text;

    public class Blink extends Text
        public function Blink():void



Basically this is a custom component that simply extends mx.controls.Text with no changes. Drop this into the com/ted/text package folder and name it and you have a custom component for Flex. As this extends mx.controls.Text, 100% of the logic in Text is present by default, my new Blink component only contains the differences. Ahhh… Inheritance. Ok lets make this component Blink like it should.

package com.ted.text{

    import mx.controls.Text;
    import flash.utils.Timer;

    public class Blink extends Text
        private var blinkTimer:Timer;

        public function Blink():void
            this.blinkTimer = new Timer( 1000 , 0 );
¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†¬†this.blinkTimer.addEventListener( “timer” , toggleText );

        public function toggleText( event:TimerEvent ):void
            if( this.visible ){
            this.visible = false;
            this.visible = true;

        public function get interval():uint
            return this.blinkTimer.delay;
        public function set interval( value:uint ):void
            this.blinkTimer.delay = value;



Ah that’s better. I added a Timer to the class and added a getter/setter called ‘interval’ to change the delay of the Timer class, and a method to change the visibility of the component. So now we have a working Blink tag for Flex 2.

So a few things to remember:

1. You can extend MXML with custom AS Classes.
2. Components are delivered within your Flex Application SWF file.
3. Old Browsers are compatible with new Players.
4. Old SWF content is always backward compatible with Flash Player.
