Kylix 3 type signature:
  THelpEvent = function(HelpType: THelpType; HelpContext: THelpContext;
       const HelpKeyword: String; const HelpFile: String;
       var Handled: Boolean): Boolean of object;


Free Pascal type signature:
  THelpEvent = function (Command: Word; Data: Longint;
    var CallHelp: Boolean): Boolean of object;


The Kylix 3 signature seems more useful to me as it clears defines the
parameters and sends all information needed to the event handler.
