The JavaFX scene graph, shown as part of the top layer in Figure 2-1, is the starting point for constructing a JavaFX application.Your camera has an internal temperature sensor and will give two warnings. It is a hierarchical tree of nodes that represents all of the visual elements of the application's user interface. It can handle input and can be rendered.Ī single element in a scene graph is called a node. Each node has an ID, style class, and bounding volume.
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. 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. 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.
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. The top layer of the JavaFX architecture shown in Figure 2-1 provides a complete set of Java public APIs that support rich client application development. These APIs provide unparalleled freedom and flexibility to construct rich client applications.
