No one answered my question about QObject::deleteLater:And what about the QObject::deleteLater() method? Any ideas how this should look like with smart pointers?
You can specify custom deleters for smart pointers. For QScopedPointer there's already a convenience class that does it:
QScopedPointer<MyObject, QScopedPointerDeleteLater> ptr = ~~~; // ptr falls out of scope, deleteLater() is called on the pointee
Such a convenience deleter should be moved to QObject, to be honest (and no, it's not usable as-is with std:: smart pointers).
Note: I didn't review Daniel's proposal so I'm not sure if this would actually work in there.
