JavaFX Runtime Architektur


JavaFX Architektur Komponenten

• Glass Windowing Toolkit: Provides native operating services, such as managing the

windows, timers, and surfaces

• Prism: Graphics pipeline that can run on hardware and software renderers

• UI Toolkit: Ties Prism and Glass together and makes them available to the JavaFX APIs

JavaFX Architektur

• Internal API

• Course-grained porting layer

− FX APIs isolated from

implementation details


implementation details

• Allows porting to completely

different systems

JavaFX Architektur

• Quantum Toolkit ties Prism and Glass

Windowing Toolkit together and makes

them available to the JavaFX layer above

in the stack


• Quantum Toolkit manages the threading

rules related to rendering versus events

handling

JavaFX Architektur

• Graphics API

− Converts the scene graph into

rendering calls

− Abstracts D3D, OpenGL, Java2D


behind a “Graphics” object

− Handles “dirty regions”, clipping, and

other optimizations

− Font support

− Rasterization• Use hardware where possible− Fast paths using shaders for ellipses, rectangles, etc.

• Reduce context switches− Looking towards possible state sorting optimizations in the future

• Fallback to software rendering when necessary− Bad drivers are the main reason for doing so

JavaFX Architektur

• Windowing API

− Windows

− Mac

− Linux


− Headless (not done)

• Provides basic OS services

− Drawing surface

− Input events

− Event queue

Scenegraph• Instead of remove/add:

− group.getChildren().remove(node);

− group.getChildren().add(0, node);

• node.toFront()

JavaFX Scenegraph


• node.toFront()

• node.toBack()

Scenegraph−node.toFront() −node.toBack()

• Details


• Details

– TextFlow, a new layout container

– Text is just a node… so you can add effects, event handlers, and animations

– You can also use CSS, FXML

TreeTableView - New in JavaFX 8

• Goal: reuse as many API, or API concepts, as possible from the TreeView and TableView controls API


DatePicker - New in JavaFX 8


Public API for CSS structure - New in JavaFX 8

• CSS styling is one of the key features for JavaFX

• CSS has been implemented exclusively in private API (com.sun.javafx.css package)

• Tools (e.g. Scene Builder) require a CSS public API


• Tools (e.g. Scene Builder) require a CSS public API

• Developers will be able to define custom CSS styles

Embedded Support - New in JavaFX 8

• JavaFX to be included in Oracle’s implementation of

– Java SE 8 (x86, x64, ARM)

– Java SE Embedded 8 (ARM)
