JavaFX
 JavaFX is a software platform for creating Rich
Internet Applications that can run across variety
of platforms[1]
 Collection of Java Packages with ability to add
fancy GUI’s to your Java application
 Groovy and Scala can also be used to write
JavaFX. JVM Languages indeed!!!
 JavaFX is official standard part of Java platform

JavaFX - History
 Formerly called F3 (Form Follows Function) and
developed by Chris Oliver at Sun Microsystems
 JavaFX was initially developed as a scripting
language however it was discontinued by Oracle
and declared dead in JavaOne (2010)[2]

Possibilities
 CSS support
 Visual effects – shadow, reflection, blur,
perspective
 Animation – cubes, cylinders, spheres etc
 Charts
 3D objects
 Touch interface
 Property bindings

JavaFX - Lingo
 Stage – Top level container for all JavaFX objects
 Scene – A scene is a hierarchical node structures
that contains all scene’s components
 Group – Group is a general purpose container
node

JavaFX Important Packages
 javafx.application: Core package on which all
JavaFX application depend
 javafx.stage: Most important class here is the Stage
class
 javafx.scene: Most important class here is the scene
class which is the container that holds all UI
elements
 javafx.scene.layout: Contains Layout Manager. Job
of Layout manager is to determine position of each
control displayed
 Javafx.scene.control: Individual controls like
buttons, text boxes and labels exist here

JavaFX LifeCycle
 Application class is responsible for managing the
lifecycle of JavaFX application
 Lifecycle steps
 Create an instance of Application
 Call init method
 Call start method
 Wait for application to End
 Call the stop method

JavaFX Lifecycle
 init (): Default implementation of init does nothing.
 One can override to perform any processing before
application UI is displayed
 start (): No default implementation and is declared
abstract.
 Your app must override this. Build and display the UI
 Wait for application to End. Typically happens when
user signals end of program
 stop(): Default implementation does not do
anything
 One can override to to perform any necessary
processing as program terminates.

JavaFX Launching
Application
 Standard entry point to Java program is the
main method
 The launch method is in Application class

JavaFX - Layouts
 Hbox – Provides a horizontal layout of its contents
in a single row
 Vbox – Provides a vertical layout of its content in
a single column
 Flow – Provides a layout of content in either
horizontal or vertical flow wrapping at current
height or boundary
 Tile – Same as flow. But all cells are uniform size.
Controlled via tileHeight and tileWidth

JavaFX Deployments
1. Launch from command line using java launcher
2. Launch as a desktop application from a JAR or
self contained application
3. View in a web page
4. Launch by clicking a link in the browser to
