# Type Hierarchy View

This view shows the hierarchy of a type. The Type Hierarchy view consists of two panes:

- Type Hierarchy tree pane
- Member list pane (optional)

## Type Hierarchy tree pane toolbar buttons

The type hierarchy tree shows supertypes, suptypes or both of a given type depending on the selection made in the toolbar.

Command | Name | Description
--- | --- | ---
| Previous Hierarchy Inputs | This menu displays a history of previously displayed type hierarchies.
| Show the Type Hierarchy | This command displays the type in its full context (i.e., superclasses and subclasses) in the Type Hierarchy view. To see for which type the hierarchy is shown, hover over the view title (e.g., "Types").
| Show the Supertype Hierarchy | This command displays the supertypes and the hierarchy of all implemented interfaces of the type in the Type Hierarchy view. The tree starts at the selected type and displays the result of traversing up the hierarchy. Note: The selected type is always at the top level, in the upper-left corner.
| Show the Subtype Hierarchy | This command displays the subtypes of the selected class and/or all implementors of the interface in the Type Hierarchy view.
