Starting with GEF is not really an easy job. The many - excellent - examples on GEF are fairly comprehensive projects with a lot of code already written. For new users who in general not have the overall view of the GEF mechanisms, investigating these examples is really a daunting task. This talk will show an incremental approach to creating a graphical editor using GEF. As an attendee, you will become familiar with the basic GEF classes during the initial steps of creating the editor. The next steps will involve adding more and more functionality using some of the more advanced GEF features. After attending this class, you will have a good starting point to begin creating your own editor. You will also have the right overview to continue exploring the other GEF examples if you want to look for functionality that was not touched. Attendees who want to join should have good Java knowledge. Familiarity with the Eclipse plug-in architecture is not really necessary but is definitely a plus.
