Firstly, I want to thank my wife for her support, especially during the crunch
period when I would lock myself in my ofce for hours to nish a chapter.
I also want to thank everyone who offered kind and encouraging words
that kept me going when I wanted to literally walk away from the project.

A special shout out goes to Sarah Cullington, my editor, who is the reason
that this book exists. Thank you, Sarah, for not giving up on the project
despite its many setbacks. Thanks to the entire Packt Publishing team
for taking the risk in a new author like myself, and in a nascent technology
like JavaFX.

Finally, I must give a shout out to to the Sun team, who saw the need for a
declarative language for rich client development on the VM, and seized the
opportunity to bring JavaFX to life. Although JavaFX is new in this space,

thanks to the hard work of these dedicated engineers, JavaFX is a complete
platform with a complete toolset for developing rich and engaging visual
applications on the JVM.

About the Reviewers
Anghel Leonard is a senior Java developer with more than 12 years of experience
in Java SE, Java EE, and the related frameworks. He wrote and published more than
20 articles about Java technologies, and more than 100 tips and tricks. He also wrote
two books about XML and Java (one for beginners and one for advanced readers), and
one about JBoss Tools 3.0, with Packt Publishing. During this time, he developed web
applications using the latest technologies on the market. In the past two years, he has
been focused on developing RIA projects for GIS elds. He is interested in bringing as
much desktop as possible to the Web; therefore, GIS applications represents a real
challenge for him.
Luca Masini is a Senior Software Engineer and Architect, who started as a game
developer for Commodore 64 (Football Manager) and Commodore Amiga (Ken il
guerriero). He soon turned to object-oriented programming, and for that, he was
always attracted by the Java language, right from its beginning in 1995.
After having found his passion, he worked as a consultant for major Italian banks,
developing and integrating the main software projects for which he often took technical
leadership. He was able to adopt Java Enterprise in an environment where COBOL was
the agship platform, converting it from mainframe-centric to distributed.
He then set his eyes upon open source technologies, starting from Linux and then
with enterprise frameworks, with which he was able to introduce some low-impact
concepts, such as IoC, ORM, MVC, and so on. For the the same reason, he was also
an early adopter of Spring, Hibernate, Struts, and a whole host of other technologies
that, in the long run, have given his customers a technological advantage, and
therefore a development cost-cut.
www.it-ebooks.info
Lately, however, his attention has been completely directed towards the simplication and

standardization of development with Java EE, and for this reason, he is working at the
ICT of a large Italian company to introduce advanced build tools (Maven and Continuous
Integration), archetypes of project, and Agile Development with plain standards.
He has worked on the following books (from Packt):
f Google Web Toolkit
f Spring Web Flow 2
f Spring Persistence with Hibernate
Gaga tu sei qui. Ah tu non fuggi. Tu mi risponderai no all'ulitmo grido.
Meenakshi Verma has been a part of the IT industry since 1998. She is experienced
in putting up solutions across multiple industry segments using SAP BI, SAP Business
Objects, and Java/J2EE technologies. She is currently based in Toronto, Canada, and
is working with Enbridge Gas Distribution.
Meenakshi has been helping with technical reviews for books published by Packt
publishing across varied enterprise solutions. Her earlier works include JasperReports
for Java Developers, Java EE 5 Development using GlassFish Application Server, Practical
Data Analysis and Reporting with BIRT', and EJB 3 Developer's Guide, Learning DOJO.
I'd like to thank my father (Mr. Bhopal Singh) and mother (Mrs. Raj Bala) for
laying a strong foundation in me and giving me their unconditional love and
support. I also owe thanks and gratitude to my husband (Atul Verma) for his
encouragement and support throughout the review of this book, and many
others: my four year old son (Prieyaansh Verma) for giving me the warmth
of his love despite my hectic schedules, and my brother (Sachin Singh) for
always being there for me.

Introduction
Today, in the age of Web 2.0, AJAX, and the iPhone, users have come to expect their applications
to provide a dynamic and engaging user interface that delivers rich graphical content, audio,
and video, all wrapped in GUI controls with animated cinematic-like interactions. They want
their applications to be connected to the web of information and social networks available
on the Internet.
www.it-ebooks.info
Getting Started with JavaFX
8
Developers, on the other hand, have become accustomed to tools such as AJAX/HTML5
toolkits, Flex/Flash, Google Web Toolkit, Eclipse/NetBeans RCP, and others that allow them
to build and deploy rich and web-connected client applications quickly. They expect their
development languages to be expressive (either through syntax or specialized APIs) with
features that liberate them from the tyranny of verbosity and empower them with the ability
to express their intents declaratively.
The Java proposition
During the early days of the Web, the Java platform was the rst to introduce rich content
and interactivity in the browser using the applet technology (predating JavaScript and even
Flash). Not too long after applets appeared, Swing was introduced as the unifying framework
to create feature-rich applications for the desktop and the browser. Over the years, Swing
matured into an amazingly robust GUI technology used to create rich desktop applications.
However powerful Swing is, its massive API stack lacks the lightweight higher abstractions

that application and content developers have been using in other development environments.
Furthermore, the applet's plugin technology was (as admitted by Sun) neglected and failed in
the browser-hosted rich applications against similar technologies such as Flash.
Enter JavaFX
The JavaFX is Sun's (now part of Oracle) answer to the next generation of rich, web-enabled,
deeply interactive applications. JavaFX is a complete platform that includes a new language,
development tools, build tools, deployment tools, and new runtimes to target desktop,
browser, mobile, and entertainment devices such as televisions. While JavaFX is itself built
on the Java platform, that is where the commonalities end. The new JavaFX scripting language
is designed as a lightweight, expressive, and a dynamic language to create web-connected,
engaging, visually appealing, and content-rich applications.
The JavaFX platform will appeal to both technical designers and developers alike. Designers
will nd JavaFX Script to be a simple, yet expressive language, perfectly suited for the
integration of graphical assets when creating visually-rich client applications. Application
developers, on the other hand, will nd its lightweight, dynamic type inference system, and
script-like feel a productivity booster, allowing them to express GUI layout, object relationship,
and powerful two-way data bindings all using a declarative and easy syntax. Since JavaFX runs
on the Java Platform, developers are able to reuse existing Java libraries directly from within
JavaFX, tapping into the vast community of existing Java developers, vendors, and libraries.
This is an introductory chapter to JavaFX. Use its recipes to get started with the platform.
You will nd instructions on how to install the SDK and directions on how to set up your
IDE. The chapter also provides a high-level introduction to the main features of the JavaFX
scripting language such as class creation, variable declaration, data types, JavaFX functional
programming support, sequences, and loops.

Installing the JavaFX SDK
The JavaFX software development kit (SDK) is a set of core tools needed to compile, run, and
deploy JavaFX applications. If you feel at home at the command line, then you can start writing

code with your favorite text editor and interact with the SDK tools directly. However, if you want
to see code-completion hints after each dot you type, then you can always use an IDE such as
NetBeans or Eclipse to get you started with JavaFX (see other recipes on IDEs). This section
outlines the necessary steps to set up the JavaFX SDK successfully on your computer. These
instructions apply to JavaFX SDK version 1.2.x; future versions may vary slightly.
Getting ready
Before you can start building JavaFX applications, you must ensure that your development
environment meets the minimum requirements. As of this writing, the following are the
minimum requirements to run the current released version of JavaFX runtime 1.2.
Minimum system requirements
Windows MacOSX Linux/OpenSolaris
f Windows XP (SP3) or

Library
How to do it
The rst step for installing the SDK on you machine is to download it from http://javafx.
com/downloads/
. Select the appropriate SDK version as shown in the next screenshot.
www.it-ebooks.info
Getting Started with JavaFX
10
Once you have downloaded the SDK for your corresponding system, follow these instructions
for installation on Windows, Mac, Ubuntu, or OpenSolaris.
Installation on Windows
1. Find and double-click on the newly downloaded installation package (.exe le)
to start.
2. Follow the directions from the installer wizard to continue with your installation.
Make sure to select the location for your installation. The installer will
run a series of validations on your system before installation starts. If the
installer nds no previously installed SDK (or the incorrect version), it will
download a SDK that meets the minimum requirements (which lengthens
your installation).
Installation on Mac OS
1. Prior to installation, ensure that your Mac OS meets the minimum requirements.
2. Find and double-click on the newly downloaded installation package (.dmg le)
to start.
3. Follow the directions from the installer wizard to continue your installation.
4. The Mac OS installer will place the installed les at the following location:
/Library/Frameworks/JavaFX.framework/Versions/1.2.
Installation on Ubuntu Linux and OpenSolaris

1. Prior to installation, ensure that your Ubuntu or OpenSolaris environment meets the
minimum requirements.
2. Locate the newly downloaded installation package to start installation. For Linux, the
le will end with *-linux-i586.sh. For OpenSolaris, the installation le will end
with *-solaris-i586.sh.
3. Move the le to the directory where you want to install the content of the SDK.
4. Make the le executable (chmod 755) and run it. This will extract the content of
the SDK in the current directory.
5. The installation will create a new directory, javafx-sdk1.2, which is your JavaFX
home location ($JAVAFX_HOME).
6. Now add the JavaFX binaries to your system's $PATH variable,
(export PATH=$PATH:$JAVAFX_HOME/bin).
When your installation steps are completed, open a command prompt and validate your
installation by checking the version of the SDK.
$> javafx -version
$> javafx 1.2.3_b36
