The Graphical Editing Framework (GEF) enables developers to create client-side rich graphical editors based on existing domain models.
Eclipse's GEF has a steep learning curve, and at times it can be difficult to understand even for developers fully accustomed to it. There are a number of technical challenges associated with using GEF that developers should be aware of and know how to handle.
We discuss difficulties that GEF developers face, and we enumerate ways to overcome them. Topics include using GEF correctly, implementing features not provided by the framework, and avoiding misuses of GEF that result in errors and bugs. In particular we present thoughts on MVC logic separation, the role of edit policies, customized layouts and graphical techniques, and potential threading concerns. The tips and insights provided by this talk are useful for both new and experienced GEF developers.
