| <p dir="ltr">The Graphical Editing Framework (GEF) allows developers |
| to create a rich graphical editor from an existing application model. GEF |
| consists of 2 plug-ins. The <b>org.eclipse.draw2d</b> plug-in provides a layout |
| and rendering toolkit for displaying graphics. |
| The developer can then take advantage of the many common operations provided |
| in GEF and/or extend them for the specific domain. GEF employs an MVC (model-view-controller) architecture |
| which enables simple changes to be applied to the model from the view.</p> |
| <p dir="ltr">GEF is completely application neutral and provides the groundwork to build almost any application, |
| including but not limited to: activity diagrams, GUI |
| builders, class diagram editors, |
| state machines, and even WYSIWYG text editors. The Logic Example, one of the |
| provided examples, is pictured below.<p><img src="images/LogicExample.jpg?cvsroot=Tools_Project"> |
