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.
