■ An API included in Java SE 7/8

for UI development

■ The successor to Java Swing

■ Not the JavaFX Script language

JavaFX is:

To Get JavaFX, Download Java 7

To Develop JavaFX, Use Your Fav IDE

Start Here: http://javafxcommunity.com

Download JDK 8 Early Access Release

Download Samples (e.g. Ensemble 8)http://jdk8.java.net/download.html

Ensemble in Mac App Store

Get Pro JavaFX 2 Book Resources

First chapter and all code samples available

Creating a User Interface

The MetronomeTransition

example is in the Pro JavaFX 2

code download

Extend javafx.application.Application

Override the Application start() Method

Create a Scene

Populate the Scene Graph

Handle Events

Call the Animation Methods

Animate the Circle

Bind UI Properties to Animation Status

Setup and Show the Stage

Some New Java Features in JDK 8

■ Nashorn JavaScript Engine

■ Date & Time API

■ Bulk data operations for collections

■ Lambda expressions and virtual extension methods

A Lambda Expression (Closure) is…

…a function that that may have parameters,

an expression or block of code, optionally

returning a value.

e -> anim.playFromStart()

Event Handling w/Anon Inner Classes

Any interface that has exactly one abstract method is known as a

functional interface, and may be replaced by a lambda expression.

Replace with Lambda Expression

The type of the lambda is inferred by the compiler as EventHandler<ActionEvent> because the onAction() method

takes an object of type EventHandler<ActionEvent>.

Because EventHandler has a single method handle() the lambda

expression must be an implementation of the handle() method.

Simplify the Lambda Expression

The parameter in this lambda expression must be an ActionEvent, because that is the type specified by the

handle() method of the EventHandler interface.

We can therefore simplify this lambda expression

because the parameter type is inferred.

Lose the Parentheses

When a lambda expression has a single parameter and

its type is inferred, the parentheses are not required

Lose the Braces

Because the block of code in our lambda expression

contains only one statement, we can lose the braces.

MetronomeTransition w/Lambdas

New JavaFX Features in JDK 8

■ New Modern Theme: Modena

■ JavaFX 3D

■ Rich Text

■ TreeTableView

■ DatePicker

■ Public API for CSS structure

■ WebView Enhancements

■ Embedded Support

New Modern Theme: Modena

http://fxexperience.com/2013/03/modena-theme-update/

“JavaFX 3D gives you the ability to use 3D geometry, cameras, and lights in JavaFX.”

JavaFX 3D

JavaFX 3D Application Example

http://fxexperience.com/2013/02/javafx-3d-early-access-available/

Mesh Geometry (3D Shapes)

■ Predefined shapes

■ Box

■ Cylinder

■ Sphere

■ User-defined shapes

■ Using TriangleMesh / MeshView

https://wikis.oracle.com/display/OpenJDK/SphereAndBox.java

Creating Primitive Shapes and Materials

3D Materials and Textures

■ PhongMaterial has these properties

■ Ambient color

■ Diffuse color, diffuse map

■ Specular color, specular map

■ Specular power

■ Normal map

■ Self-illumination map

https://wikis.oracle.com/display/OpenJDK/3D+Features

3D Lights

■ Lights are nodes in the scene graph

■ PointLight

■ AmbientLight

■ Default light provided if no active lights

https://wikis.oracle.com/display/OpenJDK/3D+Features

Lights, Camera, Action!

Tip: The camera is a node in the scene graph, so it is moveable

Rich Text

■ Use Cases

■ text editor ● code editor ● mixed style Labels, buttons, cells ●

headings ● descriptions ● large textual content ● etc.

■ Details

■ TextFlow, a new layout container

■ Text is just a node… so you can add effects, event handlers, and

animations

■ You can also use CSS, FXML

https://wikis.oracle.com/display/OpenJDK/Rich+Text

Rich Text Examples

TreeTableView

■ Goal: reuse as many API, or API concepts, as possible from the

TreeView and TableView controls API

https://wikis.oracle.com/display/OpenJDK/TreeTableView

DatePicker

Public API for CSS structure

■ CSS styling is one of the key features for JavaFX

■ CSS has been implemented exclusively in private API

(com.sun.javafx.css package)

■ Tools (e.g. Scene Builder) require a CSS public API

■ Developers will be able to define custom CSS styles

https://wikis.oracle.com/display/OpenJDK/CSS+API+to+support+custom+UI+Controls

WebView Enhancements

■ Nashorn JavaScript engine

■ https://blogs.oracle.com/nashorn/entry/open_for_business

■ WebSocket

■ http://javafx-jira.kenai.com/browse/RT-14947

■ Web Workers

■ http://javafx-jira.kenai.com/browse/RT-9782

Embedded Support

■ JavaFX to be included in Oracle’s implementation of

■ Java SE 8 (x86, x64, ARM)

■ Java SE Embedded 8 (ARM)

■ Java SE Embedded 8 will include a subset of the JavaFX

features to be released in the desktop version

■ No WebView support

■ No media support
