Talk:Qt thread-safe singleton

(not sure if this is the right place for comments)

With the newest update to this page (Dec 2016) https://wiki.qt.io/index.php?title=Qt_thread-safe_singleton&oldid=29503 , I cannot compile the code. Basically, when I call

Singleton<Origo>::Instance(MyClass::CreateInstance)

I get:

../app/include/app/Singleton.h:38:29: error: cannot initialize a parameter of type 'Type' (aka 'void *(*)()') with an lvalue of type 'CreateInstanceFunction' (aka 'MyClass *(*)()'): different return type ('void *' vs 'MyClass *')
    Singleton::create.store(create);

I THINK the fix for this is to change the declaration of create to:

static QBasicAtomicPointer<T* (void)> create;

(and same with the template instantiation at the end)

Does this make sense?

==Original version? Is there a way to see the original content of this page? I'm assuming the info was moved somewhere, but I can't find it?
