If you have something like:

  MyClass = class
  public
    procedure MyMethod(Param1, Param2: Integer); virtual;
  end;

  MyOtherClass = class(MyClass)
  public
    procedure MyMethod(Param1, Param2: Integer); override;
  end;

you can use inherited like:

  procedure MyOtherClass.MyMethod(Param1, Param2: Integer);
  begin
    inherited;
  end;

or like:

  procedure MyOtherClass.MyMethod(Param1, Param2: Integer);
  begin
    inherited MyMethod(Param1, Param2);
  end;

Both are the same. Delphi nows that MyClass.MyMethod needs 2 params, and
passes  them to the inherited method.
