Can I use a closure on an event handler (ie, TButton OnClick)

Question

If I try to use a closure on an event handler the compiler complains with :

Incompatible types: \"method pointer and regular procedure\"

which I understand..

Answer 1

@Button1.OnClick := pPointer(Cardinal(pPointer( procedure (sender: tObject) 
begin 
  ((sender as TButton).Owner as TForm).Caption := 'Freedom to anonymous methods!' 

end )^ ) + $0C)^;

works in Delphi 2010
