A quick review of terms

JavaFX Script

JavaFX Script JavaFX Mobile

JavaFX Mobile •Complete Mobile Phone Stack •Think “Google Android”

JavaFX Script • Formerly known as F3 •A new Java-like scripting language specifically for RIAs • Think Silverlight, Flex, or AIR

“ The write once, run anywhere portability of Java technology has helped make it the world's most widely deployed application platform. Now, Sun is introducing JavaFX Script, a highly productive scripting language that enables content developers to leverage the enormous popularity of Java to create rich applications and services for deployment on the widest range of platforms - from mobile devices to set- top boxes and Blu-ray Discs to desktops. ”

The Language

Interpreted vs. Compiled

Interpreted ‣ Starting point for language ‣ Proof of Concept only ‣ In process of deprecation ‣ But has current IDE Support

Compiled ‣ Official language tool, javafxc ‣ Built on top of javac ‣ Open Source ‣ Work In Progress, but very usable

Bind Operator ‣ Automatic binding of form element to data model ‣ Core JDK has no equivalent ‣ Libraries such as Swinglabs only partially accomplish this for Swing ‣ Built on Beans Binding JSR 295 library

Bean Binding Code Demo

Threads ‣ DO, DOLATER currently in interpreter

Threads “(Working on SwingWorker wrapper in compiler) so it is as easy (possibly easier) to use as AJAX's XMLHttpRequest” -Tom Ball

The Compatibilty Secret ‣ Swing based rendering on PC devices ‣ Other rendering engine for smaller devices such as Blu-Ray

SceneGraph Effect ‣ Objectifying nodes Composite Node ‣ Binding nodes together ‣ Adding behavior to TextField Box composite nodes ‣ Standalone Java library Radial Gradient SimpleLabel

JavaFX 2D Tutorial Code Demo

Animation ‣ Interpreted: picks.opacity = [0, .01..1] dur 1000 linear ‣ Compiled: Key frames, timeline

Animation As many as 500 lines of Swing code equivalent to 10 of JavaFX

Keyframe Animation ‣ Next step in JavaFX animation ‣ Advanced capabilities ‣ Currently in compiler in rough state

Designers vs. Coders

“ Sun’s JavaFX Tools are turning the workflow sideways ” James Gosling Source: http://www.regdeveloper.co.uk/2008/01/24/javafx_tools_adobe/

“ Our architecture is more like the coder does this part and the artist does this part, and then the artist can do the plugging in [of the design] themselves. They can update the artwork and the [developer] guy can update the code, and they are talking to the tool together. ” It's not conditional on the other. James Gosling Source: http://www.regdeveloper.co.uk/2008/01/24/javafx_tools_adobe/

Sun Microsystems is working on interoperability between design tools from Adobe Systems and its upcoming JavaFX tools for application developers building rich application interfaces and rich-internet applications (RIAs). James Gosling, Sun vice president and fellow, told Register Developer that Sun is working to ensure interoperability - rather than provide its own design tools. “ We are putting a lot of effort into interoperability with the Adobe tools - a lot of the Adobe tools are wired into the neurons of the artists of the world. We are not trying to be a ” completely isolated island that has all the tools for everybody. James Gosling Source: http://www.regdeveloper.co.uk/2008/01/24/javafx_tools_adobe/
