Mission

The goal of the GEF project is to build a graph editing library that can be used to construct many, high-quality graph editing applications. Some of GEF's features are:

  • A simple, concrete design that makes the framework easy to understand and extend.
  • Node-Port-Edge graph model that is powerful enough for the vast majority of connected graph applications.
  • Model-View-Controller design based on the Swing Java UI library makes GEF able to act as a UI to existing data structures, and also minimizing learning time for developers familiar with Swing.
  • High-quality user interactions for moving, resizing, reshaping, etc. GEF also supports several novel interactions such as the broom alignment tool and selection-action-buttons.
  • Generic properties sheet based on JavaBeans introspection.
  • XML-based file formats based on the PGML standard (soon to support SVG).
