The Graphical Editing Framework (GEF) provides framework technology to create rich graphical applications, standalone as well as integrated with the Eclipse Workbench UI, as well as end-user tools in terms of a Graphiz DOT authoring component (DOT) and a tag cloud renderer component (Cloudio). The current GEF4 production components are: Common, Geometry, FX, MVC, Graph, Layout, Zest, DOT, and Cloudio). They are lightweight by intention and (with the exception of Cloudio) are based on JavaFX as a modern rich-client rendering technology.The legacy components Draw2d 3.x, GEF (MVC) 3.x, and Zest 1.x are still maintained but will not be developed further. As they are still an integral part of the Eclipse ecosystem we continue to provide service releases but will not fix any issues that require to break its API.
