A JFace Viewer provides the user with a view of objects using a single content provider, label provider, sorter and filter. The Common Navigator Framework (CNF) extends this idea by allowing a single view to dynamically use multiple and unrelated sets of content providers, label providers, sorters and filters. These can be activated in the view depending on declarative expressions or using API calls. The CNF implemented by the org.eclipse.ui.navigator plugin.

The data URI scheme is a URI scheme (Uniform Resource Identifier scheme) that provides a way to include data in-line in web pages as if they were external resources. This technique allows normally separate elements such as images and style sheets to be fetched in a single HTTP request rather than multiple HTTP requests, which can be more efficient.

In this article, we discuss the drag and drop facilities provided by JFace and the Eclipse platform UI. After reading this, you will know how to add drag and drop support to your own Eclipse views, and how that support will interact with the standard views in the Eclipse platform. Along the way, we'll also discuss that keyboard relative of drag and drop: cut and paste. You'll learn that putting your own custom objects on the clipboard is easy once you've figured out the basics of drag and drop. This article is intended to be read as a companion to the SWT drag and drop article.
