The Extract Subclass refactoring enables extracting certain members of a class into a subclass.
To extract a Subclass
Select the desired class in one of the views, or just open it in the editor.
On the main menu or from the context menu, choose.
In the dialog that appears, specify the following information:
Name of the new subclass.
Members to be included in the subclass.
Proceed with the refactoring.

fv in the initial class, CLion highlights the problem member in Extract Subclass dialog, as following:
Trying to proceed with extract, you will get the following warning message:
Choose Continue to ignore the problem and proceed with refactoring, or Cancel to return back and resolve it. Also you can observe the conflict in Find Tool Window.
