These facilities are available to all plug-ins. There are no secret back doors or exclusive interfacesif it can be done in the Eclipse IDE, you can do it in your application.
SWT, JFace, and the UI Workbench plug-ins combine to form a powerful UI framework that you can use to build portable, highly scalable, and customizable UIs that have the look and feel of the platform on which you are running.
