How to pass an array to a property?

Question

I am trying to pass an array of Strings and two Talignment arrays to three properties (Published). But I’m having the following mistake (which is the same for the three properties):

[dcc32 Error] uCad.pas(31): E2188 Published Property 'Columntitlename' cannot be of type ARRAY".

The code is below:

type
    TCad = class
    private
      FColumnTitleName: array of String;
      FColumnTitleAlign: array of TAlignment;
      FColumnAlign: array of TAlignment;
      function GetColumnAlign(index: Integer): TAlignment;
      function GetColumnTitleAlign(index: Integer): TAlignment;
      function GetColumnTitleName(index: Integer): String;
    public

    published
      property ColumnTitleName[index: Integer]: String read GetColumnTitleName;
      property ColumnTitleAlign[index: Integer]: TAlignment read GetColumnTitleAlign;
      property ColumnAlign[index: Integer]: TAlignment read GetColumnAlign;
  end;

implementation

function TCad.GetColumnAlign(index: Integer): TAlignment;
begin
  Result := FColumnAlign[index];
end;

function TCad.GetColumnTitleAlign(index: Integer): TAlignment;
begin
  Result := FColumnTitleAlign[index];
end;

function TCad.GetColumnTitleName(index: Integer): String;
begin
  Result := FColumnTitleName[index];
end;

end.

Does anyone know where I’m going wrong ?

Thank you.

It seems a problem similar to this

You may also have to declare a type for this array. Sometimes you cannot use the array of [something] directly.
