JavaFX is a software platform for creating and delivering desktop applications, as well as rich internet applications (RIAs) that can run across a wide variety of devices. Some key aspects of the JavaFX platform include its base classes like Application, Scene and Stage; the use of FXML for building the user interface with CSS styling and JavaScript capabilities; JavaFX properties and bindings for observing value changes; and support for animation. The JavaFX architecture provides objects, APIs and utilities to help developers create visually-engaging and responsive user experiences.

5. To get this...

6. The big button syndrome

7. Desktop apps in Java
Abstract Window Toolkit (AWT)
Swing
Event Dispatch Thread (EDT)
Complex
L&F
Old looking
Nimbus
Synthetica, JGoodies Looks, SWT Ribbon, Quaqua,
Substance, ...

8. Some tools "helped" us ...
Visual Editor
Eclipse plugin
How many JARs do I need to start creating a
UI??!!
NetBeans

9. ... or not !
So much junk code !!
Not even editable
Except outside the IDE

10. A hope shined ...
JavaOne 2007
JavaFX is announced
Rich Internet Applications (RIA)
"Seems" promising

11. ... but ...
Java + Flash + Flex
=
JavaFX
=
???

12. I am a Java developer !!
Scripting language
Similar to Flash scripting language
Unusable Java API
JARs? What's that?
Hey, I'm a Java developer !!

13. Look through the Windows
Windows Presentation Foundation
(WPF)
Works above DirectX
Introduced with .NET 3.0
XAML
Hey, I'm still a Java developer !
eface

14. And now ...

15. JavaFX 2

18. Base classes
Application
The entry point of your app
Application.launch()
Override start()
Scene
Like the content pane in Swing
Hosts a root element
Stage = JFrame
Contains a scene
stage.show();
