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, ...

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

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

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

... but ...

Java + Flash + Flex
=
JavaFX
=
???

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 !!

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

JavaFX, because you're worth it

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();

Base classes

Markup-based language
CSS styling
JavaScript capabilities
Component binding
Controller concept

Controller
Similar to master pages in ASP
Similar to a Managed Bean
Used to
manage events
update the view dynamically
...
Referenced by fx:controller in the FXML
Initializable
Used to initialize the controller after the root
element

Controller

}

@FXML
Component binding
Like JSF
Each attribute must be strictly named as the fx:id
in the FXML
Controller Method Event handler
onAction, onClosed, ... attributes
Referenced with # in FXML

@FXML
The controller
