  private
    { Private declarations }
  public
  end;

var
  Form2: TForm2;
  List:TStringList;
  i:integer=0;
implementation

{$R *.dfm}


procedure TForm2.Button1Click(Sender: TObject);
begin
    if i>0 then
    begin
        i:=i-1;
        sSkinManager1.SkinName := List[i];
    end;
end;

procedure TForm2.Button2Click(Sender: TObject);
begin
    if i<List.Count then
