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

23

http://openjdk.java.net/jeps/174





A Lambda Expression (Closure) is…

…a function that that may have parameters,

an expression or block of code, optionally

returning a value.

24

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.

New Modern Theme: Modena

33

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

35

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

36

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

38

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

39




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

Rich Text Examples

TreeTableView

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

TreeView and TableView controls API

43

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


DatePicker

44


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

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
