The Overrides tab is specific to classes. You can use this tab to override methods inherited from the superclass of the selected element.

When a class is defined as a subclass it automatically inherits the methods of its superclass. By overriding a method you are providing a new implementation of the base method with the same name and parameters as the overridden one.

The Add New Override list displays the methods that are available to be overridden. Selecting a method adds it to the list window, to the Members tab, and to the Class View.
