[Qt-interest] problem with closeEvent

[Benjamin Sonnemann]

Well, in C++ you can declare a class name without implemention details as
long as you refer to
it as a pointer and not use any member functions.
i.e in this case:

you can do sth like this:

class Foo;
class Bar{
   doSthWithFoo(Foo* foo);
}

as a pointer is always the same size (platform wise) the compiler knows what
to do there,
as its principal passing in a long int.
