E2265: Interface '%s' not mentioned in interface list (Delphi)

An implements clause references an interface which is not mentioned in the interface list of the class.

program Produce;
type
  IMyInterface = interface
  end;

  TMyClass = class(TInterfacedObject, IUnknown)
    FMyInterface: IMyInterface;
    property MyInterface: IMyInterface read FMyInterface implements IMyInterface;
  end;
end.

The example shown here uses implements with the IMyInterface interface, but it is not mentioned in the interface list.

Copy Code

program Solve;
type
  IMyInterface = interface
  end;

  TMyClass = class(TInterfacedObject, IUnknown, IMyInterface)
    FMyInterface: IMyInterface;
    property MyInterface: IMyInterface read FMyInterface implements IMyInterface;
  end;
end.

A quick solution, shown here, is to add the required interface to the interface list of the class definition. Of course, adding it to the interface list might require the implementation of the methods of the interface.
