Changing the appearance of the Hierarchy view

The Hierarchy view offers three different ways to look at a type hierarchy (use the toolbar buttons to alternate between them):

Show the Type Hierarchy displays the type hierarchy of a type. This view shows all super- and subtypes of the selected type. Type java.lang.Object is shown in the top-left corner. Interfaces are not shown.
Show the Supertype Hierarchy displays the supertype hierarchy of a type. This view shows all supertypes and the hierarchy of all implemented interfaces. The selected type is always shown in the top-left corner.
Show the Subtype Hierarchy displays the subtype hierarchy of a type. This view shows all subtypes of the selected type and all implementers of the selected interface (if the view is opened on an interface). The selected type is always shown in the top-left corner.
