The document provides an overview of JavaFX, a software platform for creating rich internet applications. It discusses application development requirements, basic key classes like Application, Stage, and Scene, and includes a sample 'Hello World' application using NetBeans. Additionally, it outlines event handling and various UI controls and layouts available in JavaFX.

4. 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.


5. 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.

6. 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.


7. 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!");

8. 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();
}
}

9. Introduction of following key classes.
Application

Stage

Scene


10. 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.


11. 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.


12. 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.


13. 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.

14. 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

15. 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

16. Layouts
- BorderPane
- HBox
- VBox
- StackPane
- GridPane
- FlowPane
- AnchorPane
- TilePane

17. 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
