2. Deployments

5. A quick review of terms

7. JavaFX Script

8. JavaFX Script
JavaFX Mobile

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

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

11. “ 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.

40. The Language

41. Interpreted vs. Compiled

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

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

44. 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

46. Bean Binding
Code Demo

47. Threads
‣ DO, DOLATER currently in interpreter

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

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

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

51. JavaFX 2D Tutorial
Code Demo

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

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

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

58. Java3D’s Successor
“
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

66. Previewing Results
‣ Live preview of code changes
‣ No compile cycle delay for testing
‣ But uses Interpreter...

72. Designers vs. Coders

73. “
Sun’s JavaFX Tools are
turning the workflow sideways
”
James Gosling

74. “ 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

75. 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.
