39.10.16 Type Hierarchy View

The Type Hierarchy View presents the inheritance and the members of a class or interface class.

Place the editor cursor on a class name, right-click and select Show > Type Hierarchy or press F4.

Select a class in the inheritance tree to view its members.

Tip: To further inspect the Type Hierarchy or see Usages of a class, right-click in the inheritance tree.

Tip: Right-click on a function or task member to override it. More details here: Override_Functions

Tip: You can use CamelCase or Simple Regex to find a specific element.

Show Supertype Hierarchy For both classes and interfaces, shows the super-classes and super-interfaces, with the selected class or interface at the root of the tree (the tree is "upside-down").

For an interface, shows the sub-classes and sub-interfaces.


Members Toolbar

39.10.16.1 Quick Type Hierarchy View

You can quickly inspect and jump to a specific parent or child in the hierarchy. Press Ctrl+T with the cursor positioned on the element name.

The Quick Type Hierarchy View will pop-up and present a filterable list with all of the selected element's hierarchy.

You can use CamelCase or Simple Regex to locate a specific element.

Select and press Enter or click to jump to the corresponding source location.

Tip: While the Quick Type Hierarchy View is open you can press Ctrl+T to switch between Full type and Supertype hierarchy.

For functions, you can also see the implementations along the hierarchy (icons are not grayed).
