Things are more complicated than that. At the very least Delphi application
must receive the message from system (using GetMessage() or other API),
determine the target object and call its Dispatch method with message as parameter.

Windows has a built-in transport for the messages, Linux doesn't. Of course there
are libraries providing similar or even better functionality, but you end up depending
on particular library.
