The LCL does just that: polling....
With not embedded application (which of course is the main target for LCL

certainly is good enough.
But at least on Windows this is certainly not necessary, as all events are
handled by the Windows message queue and automatically wake the main thread
waiting for an events in the appropriate API call.
And how does the application see the events ?
Exactly, by polling Windows to see if there is an event available...
('polling' being the operative word here)
Events do not automagically appear in your application, even under windows.
They are not interrupts.
