Views

Every class or cluster has one or more views. Every view shows the context of a class or cluster, a subset of the Eiffel system. For example, for a certain cluster, you can show only the hierarchy of the classes in it, but you could have a second view that shows only a couple of classes in it, but with all relations between them.

The view combo box, as seen in the image above, can be used to add a view or switch to a previously added one. Every class and cluster has a view "DEFAULT" that is generated automatically. If you create a new view and move for example a class around in it, the "DEFAULT" view is unaffected.

The Diagram tool provides you with the following possibilities to manipulate views:

• Adding a view
• Deleting a view
• Showing or hiding links and labels
• Removing items from a view
• Changing colors of objects
• Using the link tool
• Changing system exploration depth of objects
• Retrieving all classes into a cluster
• Minimizing a cluster and restoring it to its normal state
