JavaFX é o

sucessor doJava Swing


Disponível para...

Windows, Linux, Mac OS XE em Preview...

ARM* Apple iOS* (usando RoboVM) Android* (prototipo)

Standalone para Java 6JavaFX 2.2 vem junto com JDK 7u6+Parte do ClassPath a partir do Java SE 8


Arquitetura

Prism – renderização Direct3D em Windows OpenGL em Linux/Mac/Embedded

Public API JavaFX API Scene Graph

Scene Graph

Responsável pela UI Estrutura em Árvore Possui um nó raiz Vários nós branch e leaf


Scene Graph

Root Node – único sem um “parent”Branch Node – deriva de javafx.scene.Parent

Pode possuir outros nósLeaf Node – não possui filhos

Shapes, Images, Text, WebView, Media, Controls, Charts, etc...


Sua primeira aplicação JavaFX

public class MyApplication extends Application {

@Override public void start(Stage stage) throws Exception { URL fxml = getClass().getResource("MyApplication.fxml"); Parent root = FXMLLoader.load(fxml); Scene scene = new Scene(root); stage.setScene(scene); stage.setFullScreen(true); stage.show(); }

public static void main(String[] args) { launch(args); }

}


Properties no Swing

// Java Swingprivate static final String VALUE_PROPERTY = "value";private double value = 0;

public double getValue() { return value; }

public void setValue(double newValue) { double oldValue = value; value = newValue; firePropertyChange(VALUE_PROPERTY, oldValue, value);}


Properties no JavaFX

// JavaFXDoubleProperty value = new SimpleDoubleProperty(0);

public double getValue() { return value.get();}

public void setValue(double newValue){ value.set(newValue);}

public DoubleProperty valueProperty() { return value;}


Bindings

Binding unidirecional bind();

Binding bi-direcional bindBidirectional();


Bindings

IntegerProperty number1 = new SimpleIntegerProperty(1);IntegerProperty number2 = new SimpleIntegerProperty(2);DoubleProperty number3 = new SimpleDoubleProperty(0.5);

NumberBinding sum1 = number1.add(number2);NumberBinding result1 = number1 .add(number2) .multiply(number3);

NumberBinding sum2 = Bindings.add(number1, number2);NumberBinding result2 = Bindings .add(number1, multiply(number2, number3));


Limite de Velocidade

60 FPS

Memory Splitfor JavaFX applications

128mb best performance

64mb may work

$ sudo raspi-config


Video Framebufferfor JavaFX applications

Edit /boot/config.txt

Enable (uncomment) these options, with these values:

framebuffer_width=1280framebuffer_height=720


Exiting a JavaFX Application on Raspberry.Pi

Connect over SSH and kill the java process

$ killall -9 java

Enable the debug environment variable to enable control-C exit command

$ export JAVA_DEBUG=1$ java -cp Stopwatch.jar stopwatch.MainScreen


Final parameters for JavaFX on Raspy

Do not show virtual keyboard (optional)-Dcom.sun.javafx.isEmbedded=false

Send video to the framebuffer (required!)-Djavafx.platform=eglfb
