Work is currently being spent on developing a JavaFX-based replacement for the core of GEF (GEF4 FX, GEF4 SwtFX, GEF4 MVC), as well as further migration of the former Zest2 code base (GEF4 Layout, GEF4 Graph, GEF4 DOT, GEF4 Zest.FX). Integration builds are available on a weekly basis (see [[#Developer Resources | Developer Resources]]), and we are intending to publish a first release of the GEF4 components with the Mars simultaneous release.

A first snapshot release (0.1.0) and a bugfix release (0.2.0), including incompatible changes, have been published as part of the [http://projects.eclipse.org/projects/tools.gef/releases/3.10.0-mars GEF 3.10.0 (Mars)] and [https://projects.eclipse.org/projects/tools.gef/releases/3.10.1-mars.1 GEF 3.10.1 (Mars.1)] releases. Information about important changes from 0.1.0 to 0.2.0 can be found in [[GEF/New_and_Noteworthy/3.10.1 | New and Noteworthy in 3.10.1]]. An overview of all significant features added during the Mars release train can in addition be found in [[GEF/New_and_Noteworthy/3.10| New and Noteworthy in 3.10]]. Information on earlier achievements and plans can be inferred from the talks listed under [[#Further Reading|Further Reading]].
  
Please note that (even including the intended Mars release version) '''all GEF4 API is still provisional''', i.e. there is no released API yet. Therefore, all API-packages are exported with the x-internal directive. To differentiate them from non-API packages, all non-API packages are explicitly named as 'internal' and are either not exported by the bundle manifest, or only via an x-friends directive (if they are used in other test bundles, etc.). You may want to consult the [[GEF/Contributor_Guide | Contributor Guide]] for details on how to set up your IDE to get rid of any restricted access warnings that are caused by this policy.

Currently, we are working on the [https://projects.eclipse.org/projects/tools.gef/releases/3.11.04.0.0-neon 3.11.0/4.0.0 (Neon)] release, which will either contain a 0.3.0 or a 1.0.0 release of the [[GEF/GEF4|GEF4]] [[#Components / Reference Documentation|components]]. In either case, the release will not be compatible to the Mars.1 (0.2.0) release and will indeed include major refactorings. Please refer to [[GEF/New_and_Noteworthy/3.11| New and Noteworthy in 3.11]] to keep updated about the most important changes.

[[GEF/GEF4|GEF4]] is internally constituted of the following nine components (with their respective sub-modules).

Revision as of 03:16, 23 September 2015


GEF4 is the unified effort of the Graphical Editing Framework (GEF) project team to develop a new code base as a replacement for the current production components Draw2d 3.x, GEF (MVC) 3.x, and Zest 1.x (which are only maintained, but not actively developed further).

Being developed in parallel to maintaining the production components, GEF4 is set up in terms of smaller, more lightweight components, uses JavaFX instead of SWT as rendering technology, and allows to build up graphical applications for Eclipse (using a JavaFX-SWT-integration) as well as standalone.

Current Status

A first snapshot release (0.1.0) and a bugfix release (0.2.0), including incompatible changes, have been published as part of the GEF 3.10.0 (Mars) and GEF 3.10.1 (Mars.1) releases. Information about important changes from 0.1.0 to 0.2.0 can be found in New and Noteworthy in 3.10.1. An overview of all significant features added during the Mars release train can in addition be found in New and Noteworthy in 3.10. Information on earlier achievements and plans can be inferred from the talks listed under Further Reading.

Currently, we are working on the 3.11.0/4.0.0 (Neon) release, which will either contain a 0.3.0 or a 1.0.0 release of the GEF4 components. In either case, the release will not be compatible to the Mars.1 (0.2.0) release and will indeed include major refactorings. Please refer to New and Noteworthy in 3.11 to keep updated about the most important changes.

Please note that all GEF4 API is still provisional, i.e. there is no released API yet. Therefore, all API-packages are exported with the x-internal directive. To differentiate them from non-API packages, all non-API packages are explicitly named as 'internal' and are either not exported by the bundle manifest, or only via an x-friends directive (if they are used in other test bundles, etc.). You may want to consult the GEF Contributor Guide for details on how to set up your IDE to get rid of any restricted access warnings that are caused by this policy.

Components / Reference Documentation

GEF4 is internally constituted of the following nine components (with their respective sub-modules). The reference documentation for each component may be accessed via the component links. You may also consult the Further Reading-section for additional information.

GEF4-Components.png

Idea.png Usage of API is demonstrated by undeployed Geometry Examples.
  • GEF4 FX (FX / FX.SWT / FX.JFace) - Provides support for rendering GEF4 Geometry-based shapes, as well as abstractions that are needed in the context of graphical editors and views, i.e. visual anchor implementations and a connection abstraction. Also enhances the JavaFX-SWT-Integration with forwarding of touch gestures and provides proper support for embedding SWT Controls via a generic adapter into a JavaFX scene graph (within the context of the JavaFX SWT integration).
Idea.png Usage of API is demonstrated by undeployed FX Examples and FX SWT Examples.
  • GEF4 Graph (Graph) - Provides a simply, UI-independent data-model (Graph, Node, Edge) for representing directed graphs. Is used as data model by GEF4 DOT and underlying visualization-model for GEF4 Zest.
  • GEF4 Layout (Layout) - Provides layout algorithm implementations as well as a model facade to adapt layout model data for these algorithms.
Idea.png Usage of API is demonstrated by undeployed Layout Examples.
  • GEF4 MVC (MVC / MVC.UI / MVC.FX / MVC.FX.UI) - Provides the core model-view-controller framework to build up graphical editors and views. Provides an UI toolkit independent and a JavaFX specific layer, as well as Eclipse-UI integration for both. Can be used to build standalone and Eclipse-integrated editors and views.

  • GEF4 Cloudio (Coudio.UI) - Provides support for visualizing tag clouds. Is based on SWT/JFace, integrated in the Eclipse UI, and will (at least for now) not be ported to JavaFX.

Developer Resources

All relevant information about how to obtain our source code, where to find our Hudson build jobs, update sites (CI, milestones, releases), mailing lists, or our forum, etc. can all be found in the respective sections of the GEF project dashboard. In addition to this, there is a dedicated GEF Contributor Guide that describes how to setup a workspace, provide a patch, execute a headless Tycho-build, and more.

The reference documentation for each GEF4 component is referenced from within the components section. Each component documentation includes references to examples, where applicable.
