I can’t talk more Experience new flex.org

I can say only 1 thing about 360|Flex Atlanta “It Rocks”.

I have attended many interesting sessions

• Axel Jensen – Understanding the component LifeCycle
• Ben Clinkinbeard – Creating Polished Custom Components
• Christophe Coenraets – The Future of Data Services
• Andrew Powell – Building Java Powered Flex Applications.
• Jun Heider – Memory management and optimization
• Flex 4: What’s cooking  Deepa Subramaniam

I have delivered session on “Creating cool frontend Apps: using Flex and JavaScript” which went very well. I have demoed my experimental application “svWord” online word processor using Flex and Javascript (using Zoho Api). svWord will be online soon…

Overall it was great learning experience.

Flex Visual component are created with the class hierarchy of several ActionScript class to provide more flexibility and add more features at the different level of hierarchy.

Following is a visual representation of class hierarchy of Flex Visual Components:

Object: Object is a Top/Root Level class of AactionScript class hierarchy. | More Info…

EventDispatcher: EventDispatcher class extends object class. EvenDispacher class allows any object on the display list to be an event target. | More Info

DisplayObject: Display Object class extends object and this is the base class for all objects which can be added in the DisplayList. Display object class allows some properties (x, y, width, height )for components/Objects like MovieClip, Button, TextField etc. | More Info

InteractiveObject: InteractiveObject extends DisplayObject and it is an abstract base class for all DisplayObject with which user can interact. InteractiveObject provides some common properties like doubleClickEnabled, focusRect, tabIndex etc… and Events like all mouse Events, Keyboard Events. | More Info

DisplayObjectContainer: DisplayObjectContainer extends InteractiveObject class and it is a base shell for all containers which adds display objects in the container shell. . DisplayObjectContainer provides some common properties like numChildren, tabChildren etc and methods like addChild(), removeChilld() method related to the child display object management. .. | More Info

FlexSprite: FlexSprite is a subclass of the Player’s Sprite class and the superclass of UIComponent. It overrides the toString() method to return a string indicating the location of the object within the hierarchy of DisplayObjects in the application. The Sprite class is a basic display list building block: a display list node that can display graphics and can also contain children. | More Info

UIComponent: UIComponent extends Sprite and it is a base class for all Interactive and non Interactive component. The UIComponent class is not used as an MXML tag, but is used as a base class for other classes. | More Info

All Visual Components like VBox, HBox, Canvas, Button etc. extends UIComponent.

Hope this article will help you. Any Comments?

My topic will be covering following points and much more.

• Flex and JavaScript Hand in Hand.
• Integration and communication between Flex and JavaScript.
• Flex and Ajax Bridge.
• Simple approaches to achieve most usable UI using Flex and JavaScript.
• Building word processor using flex and javascript.
• Drag and Drop management between Flex Component and JavaScript component.
• Some Examples
• Q and A

This session will bring up light on many good technique and challenges while working with flex and JavaScript.

Following are top Open Source Frameworks:

1. Cairngorm
   “The Cairngorm micro architecture is intended as a framework for Enterprise RIA developers. If you are writing a very simple application (such as a prototype application) or an application with only a single view, then you might consider a “Model 1″ solution that doesn’t strive for the same separation of model, view, and control that Cairngorm advocates. The benefits of the Cairngorm architecture are realized when developing complex RIA applications with multiple use-cases and views, with a team of developers, and with a multi-disciplinary development team that includes designers as well as creative and technical developers.” by Adobe
   Download Cairngorm.
2. PureMVC
   “PureMVC is a lightweight framework for creating applications in ActionScript 3, based upon the classic Model-View-Controller design meta-pattern.This free, open source framework does not depend on any Flash, Flex or Apollo classes, and is therefore suitable for architecting applications on any platform running AS3.” By PureMVC
   Download PureMVC
3. Model-Glue
   “The Model-Glue family of frameworks support Web application developers by making the construction of Object-Oriented Web and Rich Internet Applications a straightforward process.
   Through a simple implementation of Implicit Invocation and Model-View-Controller, they allow applications to be well organized without sacrificing flexibility.” By Model-Glue

5. Guasax Flex Framework
   
6. ARP
   
7. Flest Framework
   
8. EasyMVC
   
9. Adobe FAST
10. Joeberkovitz’s framework

Here are some Q&A Discussed with James Gosling which are specifically for Adobe Flash / Flex / AIR.

How will JavaFX be positioned with regard to Microsoft Silverlight and Adobe AIR?
[James] : It certainly competes with both of those. I think we have a much broader and more capable API set. We’ve got a much stronger security story and cross-platform story and a really strong performance story. And I think our deliverable will be really nice.

As organizations think about building rich Internet applications or rich client applications, when should developers look at JavaFX over competing technologies?
[James] :Â “If you look at something like Flash, when you get to the much more advanced stuff — richer interfaces, more complex network protocols, more complex APIs — it really falls short.” We’ve had a platform for years that can build rich Internet applications that are extremely sophisticated.
Our issue hasn’t really been, can you build interesting rich Internet applications? But that it’s difficult. And most of our efforts really are around making a lot of it easier.

In RIA technology space Flash Platform and AJAX are leader and Microsoft (Silverlight) and SUN (JavaFX) are just coming in action.

I am sure that Flash/Flex Platform Community will have some reaction on this.
