JavaFx Introduction

JavaFx is a software platform for creating and delivering rich internet application (RIAs) that can run across a wide variety of devices.

Before version 2.0 of JavaFx, it was JavaFX was scripting language to build JavaFX application.

JavaFx 2.0 and later is now implemented as a native Java library and JavaFX Script has been scrapped by Oracle, but development is being continue in the Visage project.

JavaFx 2.x does not support the Solaris operating system or mobile phones; however as plans to integrate JavaFX to Java SE embedded 8, JavaFx for ARM processors is currently in developer preview phase.

Requirements for JavaFX application development

JavaFX 2.2.5 libraries are installed with JDK 7u11 for all supported operating systems. Note that Apple's Java SE implementation is not supported with JavaFX.

For JDK 6 you need to use standalone JavaFX 2.2.5 installation.

Browser support IE7, 8, 9, 10, firefox 3.6+, chrome latest and safari 5.1+

Graphics support NVIDIA, ATI, Intel.

You can use Netbeans, Eclipse, IntealiJ and etc.

HelloWorld in JavaFX with Netbeans

Example is created on Netbeans 7.1.2

Goto → File Menu and choose New Project

In the JavaFX application category, choose JavaFX Application. Click Next

Name the project HelloWorld and click Finish

You will have HelloWorld.java class where you can put following code and run the application.

HelloWorld in JavaFX with Netbeans

import javafx.application.Application;import javafx.scene.Scene;import javafx.scene.control.Label;import javafx.scene.layout.StackPane;import javafx.stage.Stage;

public class main extends Application { public static void main(String[] args) { launch(args); } @Override public void start(Stage primaryStage) { //Setting the Title of window. primaryStage.setTitle("Hello World!");

HelloWorld in JavaFX with Netbeans

//Creating label and setting the text. Label lbl = new Label(); lbl.setText("Say 'Hello World'"); //Creating the stackpane for layout and adding label into it. StackPane root = new StackPane(); root.getChildren().add(lbl); //Creating and setting the scene. primaryStage.setScene(new Scene(root, 300, 250)); primaryStage.show(); }}

Introduction of following key classes.

Application Stage Scene

Application

Every JavaFx application needs to extend this abstract class. This is the entry point of the JavaFx application.

JavaFx runtime does the following, in order, whenever an application id launched.- Constructs an instance of the specified Application class.- Calls the init() method.- Calls the start(javafx.stage.Stage) method.- Waits for the application to finish, which happens when either of the following occur:a.) the application calls Platform.exit()b.) the last window has been closed and the implicitExit attribute on Platform is true.- Calls the stop() method

start method is abstract and must be overridden. The init and stop methods have concrete implementations that do nothing.

Application

Values can be passed to JavaFx application. Application parameters are available by calling the getParameters() method from the init() method, or any time after the init method has been called.

JavaFX creates an application thread for running the application start method, processing input events, and running animation timelines. Creation of JavaFX Scene and Stage objects as well as modification of scene graph operations to live objects (those objects already attached to a scene) must be done on the JavaFX application thread.

Stage

The JavaFX Stage class is the top level JavaFX container. The primary Stage is constructed by the platform. Additional Stage objects may be constructed by the application.

Stage objects must be constructed and modified on the JavaFX Application Thread.

A stage can optionally have an owner Window. When a window is a stage's owner, it is said to be the parent of that stage. When a parent window is closed, all its descendant windows are closed. The same chained behavior applied for a parent window that is iconified. A stage will always be on top of its parent window. The owner must be initialized before the stage is made visible.

Scene

The JavaFX Scene class is the container for all content in a scene graph. The background of the scene is filled as specified by the fill property.

The application must specify the root Node for the scene graph by setting the root property.

A scene graph is a tree data structure.

JavaFx UI Controls

The JavaFX UI controls are built by using nodes in the scene graph. Therefore, the controls can use the visually rich features of the JavaFX platform. Here are following controls.

- Label - Button- Radio Button- Toggle Button- Checkbox- Choice Box- Text Field- Password Field- Scroll Bar- Scroll Pane- List View- Table View- Tree View- Combo Box

JavaFx UI Controls

- Separator- Slider- Progress Bar and Progress Indicator- Hyperlink- Tooltip- HTML Editor- Titled Pane and Accordion- Menu- Color Picker- Pagination Control- File Chooser

Layouts

- BorderPane- HBox- VBox- StackPane- GridPane- FlowPane- AnchorPane- TilePane

Event Handling

An event represents an occurrence of something of interest to the application, such as a mouse being moved or a key being pressed.

- Mouse Event- Key Event- Touch Event- Gesture
