A Group is a Node which can have many "child" Node elements. Every Node in a tree has a single "parent" node, with the exception of a special Node designated as the "root". Representation of a JavaFX Scene Graph.Ī general element of a scene graph in JavaFX is called a Node. Public static void main ( String args )Ĭontent in JavaFX (such as text, images, and UI controls) is organized using a tree-like data structure known as a scene graph, which groups and arranges the elements of a graphical scene. Public class Example1 extends Application Knowing all this, we can write a minimal example that launches a window in JavaFX:
After a Stage is configured and the content is added, the show() method is called. Additional Stages may be constructed as necessary. Stages control basic window properties such as title, icon, visibility, resizability, fullscreen mode, and decorations the latter is configured using StageStyle. When an Application is launched, an initial Stage is created and passed to the Application's start method. The Stage class is the top level JavaFX container. Of these methods, only the start() method is abstract and must be overridden.
Your main class should call the launch() method, which will then call the init() method and then the start() method, wait for the application to finish, and then call the stop() method. Basic Framework ClassesĬreating a JavaFX program begins with the Application class, from which all JavaFX applications are extended. If you haven't updated your Java installation in a while, head to the Java download website for the latest version. If you already develop applications with Java, you probably don't need to download anything at all: JavaFX has been included with the standard JDK (Java Development Kit) bundle since JDK version 7u6 (August 2012).
