adding an interface to a component?

[edgarasm]

please, look down my code and see whether is possible or not to do this.

IControleServico = interface
  ['{A76DC1D9-2737-4A94-91F2-ECFF002EE82A}']
  procedure AddNovoCliente(pSession_ID:String);
end;

TListViewClient = class(TListView, IControleServico)
private
  { Private declarations }
  visitors, waitingForChat, waitingForResponse : integer;
protected
  { Protected declarations }
public
  { Public declarations }
published
  { Published declarations }
end;
