Alt+8

Use this tool window to analyze and navigate through hierarchies of classes , calls, methods .

The contents of the tool window are not automatically updated as you navigate through the source code or switch between the editor tabs. The tool window shows the results of the latest hierarchy command and is updated when you run the next hierarchy command, unless the tab with one of the previously built hierarchies is pinned .

Toolbar buttons

Item	Description	Available In
	When this button is pressed, the hierarchical tree shows both the parent and child classes of the selected class, which is marked with an arrow in the tree of results. For the interfaces this button is disabled.	Class hierarchies
	Depending on the hierarchy type: For class hierarchies - when this button is pressed, the tool window shows all classes that extend the selected class. For call hierarchies - when this button is pressed, the tool window shows the callees of the selected method.	Class hierarchies Call hierarchies
	Depending on the hierarchy type: For class hierarchies - when this button is pressed, the tool window shows the hierarchy of each supertype of the current class. For call hierarchies - when this button is pressed, the tool window shows the callers of the selected method.	Class hierarchies Call hierarchies
	When this button is pressed, the elements within a tree are sorted alphabetically.	All hierarchies
Scope	Use this drop-down list to limit the scope of the current hierarchy: Project - IntelliJ IDEA traces usages of the method across the project. Test - IntelliJ IDEA traces usages of the method across the test classes. All - IntelliJ IDEA traces usages of the method across the project and the libraries. This class - the scope is limited to the current class. In addition to the pre-configured scopes, you can define your own one: select Configure from the drop-down list, and define the required scope in the Scopes dialog box that opens.	Call hierarchies
In a method hierarchy, the tree-views of the following classes are available: - where this method is defined. - where this method is not defined, but defined in the superclass. - where this method should be defined, because the class is not abstract.
	If you made any changes of the classes or the class structure, they become visible in the Hierarchy tool window only after you press this button.	All hierarchies
	Toggle the Autoscroll to source mode. When the button is pressed, every time the node is focused, the corresponding line of source code is highlighted in the editor.	All hierarchies
	When this button is pressed, the current tab will not be overwritten; instead, the results of the next command will be displayed in a new tab.	All hierarchies
