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
7
Copyright © 2012 Oracle and/or its affiliates. All rights reserved.
JavaFX Architektur
• Internal API
• Course-grained porting layer
− FX APIs isolated from
implementation details
• Allows porting to completely
different systems
8
Copyright © 2012 Oracle and/or its affiliates. All rights reserved.
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
9
Copyright © 2012 Oracle and/or its affiliates. All rights reserved.
JavaFX Architektur
• Graphics API
− Converts the scenegraph into
rendering calls
− Abstracts D3D, OpenGL, Java2D
behind a “Graphics” object
− Handles “dirty regions”, clipping, and
other optimizations
− Font support
• 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
10

− Rasterization
JavaFX Architektur
• Windowing API
− Windows
− Mac
− Linux
− Headless (not done)
• Provides basic OS services
− Drawing surface
− Input events
− Event queue
11

JavaFX Scenegraph
Scenegraph
• Instead of remove/add:
− group.getChildren().remove(node);
− group.getChildren().add(0, node);
• node.toFront()
• node.toBack()
Scenegraph
−node.toFront()
−node.toBack()

}
}
});
});
}
