Code hierarchies

Build hierarchies

In CLion, you can build the following hierarchies:

• Type hierarchies show parent and children classes of a class. To build a type hierarchy, select the desired class in the Project tool window or in the editor and call Navigate | Type Hierarchy from the main menu (or just press Ctrl+H).

  

• Call hierarchies show callers (supertypes) or callees (subtypes) of a method (Navigate | Call Hierarchy).

  

• Imports hierarchies show where the current file is included and track all files included in the current file. To build an import hierarchy, open the file in the editor or select it in the Project view, and choose Navigate | Imports Hierarchy from the main menu.

  

When built, a hierarchy can be viewed and examined in the Hierarchy tool window. By default, every new built hierarchy overwrites the contents of the current tab.

You can retain the current tab and have the next hierarchy built in a new one.

View hierarchies

Once built, hierarchies can be brought up for close examination in the Hierarchy tool window (View | Tool Windows | Hierarchy). Note that the Hierarchy tool window is not shown when there are no hierarchies to display.

See Icons and Symbols for descriptions of the Hierarchy and Structure view icons.

View structure of a file

You can examine the structure of the file currently opened in the editor using the Structure tool window or the Structure popup. By default, CLion shows all the classes and functions presented in the current file.

To have other members displayed, click the corresponding buttons on the toolbar of the Structure tool window. You can also have class members shown in the Project tool window.
