You're right. It is ofcourse actually a variant of case 3 (see original
post), only the delete call is now in a member instead of main program flow.
It is something that may confuse newbies to no end, so it's good you mention
it.

BTW, exactly the same can be achieved by "delete wnd" instead of
"wnd->DestroyWindow()". I personally find this much clearer.
