A Delphi event is nothing more than a method pointer. When the
circumstances corresponding to an event occur, the component inspects
its event property. If the property is non-nil, the component invokes
the event handler. That simply calls the method. It's just like calling
any other method. Control is transfered from the caller to that method,
and code in the caller does not run until the method returns.
