The top layer of the JavaFX architecture shown in Figure 1 provides a complete set of public APIs that support rich client application development. State: Transforms (positioning and orientation of nodes), visual effects, and other visual state of the contentĮffects: Simple objects that change the appearance of scene graph nodes, such as blurs, shadows, and color adjustmentįor more information, see the Working with the JavaFX Scene Graph document Nodes: Shapes (2-D and 3-D), images, media, embedded web browser, text, UI controls, charts, groups, and containers The javafx.scene API allows the creation and specification of several types of content, such as: Animating various graphics in the scene graph can be accomplished quickly using the javafx.animation APIs, and declarative methods, such as XML doc, also work well. Unlike in Swing and Abstract Window Toolkit (AWT), the JavaFX scene graph also includes the graphics primitives, such as rectangles and text, in addition to having controls, layout containers, images and media.įor most uses, the scene graph simplifies working with UIs, especially when rich UIs are used. It can also have the following:Įvent handlers (such as mouse, key and input method) With the exception of the root node of a scene graph, each node in a scene graph has a single parent and zero or more children. Each node has an ID, style class, and bounding volume. It can handle input and can be rendered.Ī single element in a scene graph is called a node. It is a hierarchical tree of nodes that represents all of the visual elements of the application's user interface. The JavaFX scene graph, shown as part of the top layer in Figure 1, is the starting point for constructing a JavaFX application. Although these components are not exposed publicly, their descriptions can help you to better understand what runs a JavaFX application. It is composed of subcomponents that include the new JavaFX high performance graphics engine, called Prism the new small and efficient windowing system, called Glass a media engine, and a web engine. Below the JavaFX public APIs lies the engine that runs your JavaFX code. The sections following the diagram describe each component and how the parts interconnect. See the What is JavaFX 2 document for a summary of what JavaFX has to offer.įigure 1 illustrates the architectural components of the JavaFX platform. The JavaFX is a set of Java libraries designed to enable developers to create and deploy rich client applications that behave consistently across platforms.
