Disclaimer: This is Code-HeavyTHE FOLLOWING IS INTENDED TO STIMULATE CREATIVE USE OF JVM LANGUAGES. AFTER WATCHING THIS PRESENTATION YOU MAY FEEL COMPELLED TO START LEARNING A NEW JVM LANGUAGE. THE PRESENTERS ARE NOT LIABLE FOR ANY INNOVATION, BREAKTHROUGHS, OR NP-COMPLETE SOLUTIONS THAT MAY RESULT.

Programming LanguagesJavaFX 2.0 APIs are now in JavaPure Java APIs for all of JavaFXBindingand Sequences exposed as Java APIsFXML Markup for toolingEmbrace all JVM languagesGroovy, Scala, Clojure, JRubyFantom, Mira, Gosu, Jython, etc.JavaFX Script is no longer supported by OracleExisting JavaFX Script based applications will continue to runVisageis the open-source successor to the JavaFX Script language

JavaFX in JavaJavaFX API uses an enhanced JavaBeans patternSimilar in feel to other UI toolkits (Swing, Apache Pivot, etc.)Uses builder pattern to minimize boilerplate

Example Applicationpublic class HelloStage extends Application { @Override public void start(Stage stage) { stage.setTitle("Hello Stage");stage.setWidth(600); stage.setHeight(450);Group root = new Group(); Scene scene = new Scene(root);scene.setFill(Color.LIGHTGREEN);stage.setScene(scene);stage.show(); } public static void main(String[] args) { launch(HelloStage.class, args); }}

Example Application Using Builderspublic class HelloStage extends Application { @Override public void start(Stage stage) {stage.setTitle("Hello Stage");stage.setScene(SceneBuilder.create().fill(Color.LIGHTGREEN).width(600).height(450) .build());stage.show();} public static void main(String[] args) { launch(HelloStage.class, args); }}

BindingUnquestionably the biggest JavaFX Script innovationSupported via a PropertyBindingclassLazy invocation for high performanceStatic construction syntax for simple casese.g.: bind(<property>), bindBiDirectional(<property>)

Observable Pseudo-PropertiesSupports watching for changes to propertiesImplemented via anonymous inner classesWill take advantage of closures in the future

Observable Pseudo-Propertiesfinal Rectangle rect = new Rectangle();rect.setX(40);rect.setY(40);rect.setWidth(100);rect.setHeight(200);rect.hoverProperty().addListener(new ChangeListener<Boolean>() {});

Observable Pseudo-Propertiesfinal Rectangle rect = new Rectangle();rect.setX(40);rect.setY(40);rect.setWidth(100);rect.setHeight(200);rect.hoverProperty().addListener(new ChangeListener<Boolean>() {});The property we want to watch

Observable Pseudo-Propertiesfinal Rectangle rect = new Rectangle();rect.setX(40);rect.setY(40);rect.setWidth(100);rect.setHeight(200);rect.hoverProperty().addListener(new ChangeListener<Boolean>() {});Only one listener used with generics to specify the data type

Observable Pseudo-Propertiesfinal Rectangle rect = new Rectangle();rect.setX(40);rect.setY(40);rect.setWidth(100);rect.setHeight(200);rect.hoverProperty().addListener(new ChangeListener<Boolean>() { public void changed(ObservableValue<? extends Boolean> property, Boolean oldValue, Boolean value) { }});Refers to the Rectangle.hoverProperty()

Observable Pseudo-Propertiesfinal Rectangle rect = new Rectangle();rect.setX(40);rect.setY(40);rect.setWidth(100);rect.setHeight(200);rect.hoverProperty().addListener(new ChangeListener<Boolean>() { public void changed(ObservableValue<? extends Boolean> property, Boolean oldValue, Boolean value) { rect.setFill(rect.isHover() ? Color.GREEN : Color.RED); }});

Sequences in JavaReplaced with an Observable ListPublic API is based on JavaFX sequencesInternal code can use lighter collections APIJavaFX 2.0 also has an Observable Map

A Little About ClojureStarted in 2007 by Rich HickeyFunctional Programming LanguageDerived from LISPOptimized for High Concurrency… and looks nothing like Java!49(def hello (fn [] "Hello world"))(hello)

Clojure Syntax in One SlideSymbolsnumbers – 2.178ratios – 355/113strings – “clojure”, “rocks”characters – \a \b \c \dsymbols – a b c dkeywords – :alpha :betaboolean – true, falsenull - nilCollections(commas optional)Lists(1, 2, 3, 4, 5)Vectors[1, 2, 3, 4, 5]Maps{:a 1, :b 2, :c 3, :d 4}Sets#{:a :b :c :d :e}50(plus macros that are syntactic sugar wrapping the above)

Why Scala?Shares many language features with JavaFX Script that make GUI programming easier:Static Type Checking – Catch your errors at compile timeClosures – Wrap behavior and pass it by referenceDeclarative – Express the UI by describing what it should look likeScala also supports Type Safe DSLs!Implicit Conversions – type safe class extensionOperator Overloading – with standard precedence rulesDelayedInit / @specialized – advanced language features58
