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

‣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

Bind Operator

Bean BindingCode Demo

‣ DO, DOLATER currently in interpreter

Threads

Threads

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

-Tom Ball

‣Swing based rendering on PC devices

‣Other rendering engine for smaller devices such as Blu-Ray

The Compatibilty Secret

Effect

‣Objectifying nodes

‣Binding nodes together

‣Adding behavior to composite nodes

‣Standalone Java library

Animation

‣ Interpreted:picks.opacity = [0, .01..1] dur 1000 linear

‣ Compiled:Key frames, timeline

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

Animation

‣Next step in JavaFX animation

‣Advanced capabilities

‣Currently in compiler in rough state

Specifically, we are working on a new 3D scene graph, as part of the JavaFX player, that will complement the 2D Scenario scene graph. Its initial focus will be 3D effects, casual games, and simple 3D viewing applications...

Designers vs. Coders

Sun’s JavaFX Tools are turning the workflow sideways

“”

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.

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.
