What I do is:

• double click at the interface
• then click View Call Hierarchy

How is it possible to see View Call Hierarchy by clicking at the interface?

CodePudding user response：

That question is about implementations of an interface method. You want implementations of the interface as a whole.

Just right-click the interface and click "Go To Implementation (Ctrl F12)", it's right there in the menu name. This will open the class if one exists, or show a list of classes if multiple implement it.
