Let's say that it doesn't do that in Delphi.

This is a good point, which depends actually on the toolkit used.
Personally, I think that the event 'OnClick' should be separated out in
'OnClick' (clicked by user) and 'OnChange' (State of checkbox changed)
But this will give compatibility problems.

If I recall correctly, Kylix has the same problem because Qt handles
it differently from native Win32.
