What is Flex?

First and foremost Flex is a framework for the Flash Platform (now called the Adobe Platform)

Adobe has a commercial IDE: Flex Builder

Flex is a declarative language: MXML (XML based)

Flex is the answer for developers who hate Flash and HTML

If your app is a __, Flex would be __

Car Flex would be the chassis and the engine
(you to code the exterior, interior, and a radio)

Baby Flex would be the organs, bones, cells, initial DNA, and some exterior you choose the hair and eye color, then program some attitude.

House/Building Flex would be pre-fab parts, the foundation, plus plumbing & central air.

Why Flex?

It's RAD (Rapid Application Development)

Not complicated

Large backing

Large community

Publish for the web or desktop software (AIR)

Open sourced

Cost: FREE WHAT?! FREE? YES, FREE!

Everyone else is doing it! (It's the future)

Myths of Flex

You need a Flex Player - WRONG!
(Flash Player is the only thing you need)

Flex is proprietary WRONG!
(Flex is open source opensource.adobe.com)

Flex only loads XML/RSS WRONG!
(Binary, Sockets, RPC, TXT, PHP/Java/.Net, ...)

Flex costs money to run/use/get WRONG!
(Flex is free: SDK, Framework, knowledge)

No back button or deep-linking WRONG!
(Flash/Flex have had this capability since v6)

Similarities Between XHTML & Flex

Both are XML based languages/markup (tags)

Both can use higher level interactive languages:
- HTML has JavaScript
- Flex has ActionScript

Both support CSS

Both have forms, text control, and support for the media trio (images, video, audio)

Both support custom namespaces

Both are free

Both support the back and forward buttons

Differences Between HTML & Flex

Flex and ActionScript are compiled languages, not interpreted like HTML/CSS/JS/PHP
- Compiled Outputs = SWF & AIR file formats

HTML, by default, uses multiple files/pages;
Flex can be multiple pages or just one file.

HTML doesn't have a framework it can't.

Web standards HTML/CSS render natively, while Flash Player needs to be installed for Flash/Flex content... until Firefox 3 & IE8!!!

Similarities Between Flash & Flex

Both run on the Flash Player and AIR runtime

Both are ActionScript at their hearts same code, same effects & filters, same capabilities.

Both have commercial and free IDE's
Adobe.com, OSflash.org, RIAforge.org

Both can share components (SWC), classes, and media (SWF, FLV, MOV/MP4/M4V, AAC/MP3/M4A)

Both have a connection to open source.

Differences Between Flash & Flex

Flash has a time line, and art design tools

Flash is targeted for design and animation

Flash does not have a native framework

Flash isn't a language

Flash will get you a rich, cool web site

Flex is only code - Flex Builder has design tools for theming (CSS)

Flex is targeted for any developer.

Flex is a framework.

Flex is a language.

Flex really speeds up development of rich applications (RIA's)

RIA (Rich Internet Applications)

Marketing term for some; way of life for others.

Rich interface design, multimedia (images, video, audio).

Needs to do something on or with the Internet.

Application needs to do something, for someone (hopefully useful and world changing)

Examples: Twitter client, Adobe Media Player, Adobe Premiere Express, Agile Agenda, Adobe Photoshop Express, Saffron UML, ...

(Multimedia, Marketing/Business/Sales, Development, Medical, Social, Government)

MXML & ActionScript Code

MXML:

ActionScript:

package com.richmediainstitute.drupalcon.2008.boston
{
import mx.flash.utils.*;

public class MyActionScriptClass
{
public function DynamicCall()
{
var someText:String = 'I like Drupal';
trace(someText);
}
}
}

Ready to see a fight?!

Rules: No external classes, libraries, frameworks, or hacks

XHTML & JS vs. MXML & AS

Round 1:
Forms


Forms:

Form tag (container)

Input fields

Select Lists/Menus

Buttons

File [upload] field

Radio Buttons/Groups

Checkboxes

Textarea

Fieldset*

Everything XHTML has, plus...

Restricted Input

Formatters/Validators (credit card, currency, date, string, email, number, phone, regexp, social security, zipcode)

Color Picker

Numeric Stepper

Date Field & Chooser

Sliders (Horizontal & Vertical)

Required fields option


Round 2:
XML


XML:

Reads or renders XML... that's it.

Everything XHTML has, but amazingly better...

E4X (ECMA)

XPath


Round 3:
Data Visualization


Data Visualization:

Tables (?)

Lists

Images

Text

Everything XHTML has, plus...

Advanced Data Grids

OLAP DataGrid

Rich Text Editor

Tree

Images/Video/Audio

Sound Visualization

Sliders (Horizontal & Vertical)

Charts every kind!


Round 4:
Data Connectivity


Data Connectivity:

Ajax (load/send XML)

Oh, so much more...

XML, TXT

RPC

WSDL (SOAP)

CRUD wizards
(ColdFusion, PHP, Java, .Net)

Sockets (XML/Binary)

Data/Object Bindings

External Interfaces
(JS, C/C++, Java, ...)

Progress Bars

Security models


Round 5:
User & System Level Interactivity

Interactivity:

Clicks

Some Events

File [reference] field

Cursors

History Management (back/forward buttons, deep links for pages)

Load/Render Plug-in Media & Objects

Capable of transitions

Mouse position

Basic printing


Hehe, that's nothing...

Tons of events
(callbacks, hooks, and your custom events)

Multi-file Upload

Better mouse control
(track, hide, change, stack, detect)

External Interfaces
(JS, C/C++, Java, ...)

Transitions & Effects (real)

Object History and State Management

AS can load more AS

Modul mode (real), and True Full-screen support

Powerful [controlled] printing

Flex Wins!

right!?!

Flex's Display & Event Model

Display (UI) ModelEvent Model

UI Elements & Components

A lot to use and choose from

Layout Containers & Navigators (~30)

UI Components (>25)

Charts (10)

No depth level so you can make components and sub-components galore

Every UI Element/Component has a lot of features available (styling, effects, events, data)

CSS in Flex/Flash

CSS can be loaded
Load the same CSS that your XHTML uses

CSS can be embedded

CSS can be shared

CSS can be compiled (SWF)

Code your own custom CSS features, like the open-sourced Degrafa project (new)

Drupal Integration

AMFPHP (module) this is a binary gateway for you to pass your data through and send to Flex/Flash in an insane speed. Super tiny versus XML.

Services (module) make services (functions) that your Flex/Flash calls to get and send data (XML or AMFPHP)

SWFaddress (module) old deep-linking lib

SWFobject (module) embed SWF properly*

SWFtools (module) a bunch of stuff (I don't use)

VISIT THE FLEX + DRUPAL SESSION TOMORROW

*Microsoft announced after April there shouldn't be a need for SWFobject, but Adobe isn't taking that chance and plans to adopt SWFobejct.

SUPER NEW STUFF (Flash 10)

Flash (FLA) files are now XML (XFL)

Flash will have 3D built-in (Papervision engine)

Flash will have smart animation(no keyframes and support for bones or inverse kinematics)

Hydra will change effects forever

SUPER NEW STUFF (Flex 4)

Thermo will be the designer-developer liaison

If Flash Player has 3D, Flex will have 3D

Database Drivers NO WAY!

Public beta and staying open-source
