+ \class QScopedPointer
+ \brief The QScopedPointer class stores a pointer to a dynamically allocated object, and deletes it upon destruction.
+ \since 4.6
+ \reentrant
+ \ingroup misc
+
+ Managing heap allocated objects manually is hard and error prone, with the
+ common result that code leaks memory and is hard to maintain.
+ QScopedPointer is a small utility class that heavily simplifies this by
+ assigning stack-based memory ownership to heap allocations, more generally
+ called resource acquisition is initialization(RAII).
+
+ QScopedPointer guarantees that the object pointed to will get deleted when
+ the current scope dissapears, and it also has no way of releasing
+ ownership, hence clearly communicating the lifetime and ownership of the
+ object. These guarantees are convenient when reading the code.
+
+ Consider this function which does heap allocations, and have various exit points:
+
+ \snippet doc/src/snippets/code/src_corelib_tools_qscopedpointer.cpp 0
+
+ It's encumbered by the manual delete calls. With QScopedPointer, the code
+ can be simplified to:
+
+ \snippet doc/src/snippets/code/src_corelib_tools_qscopedpointer.cpp 1
+
+ The code the compiler generates for QScopedPointer is the same as when
+ writing it manually. Code that makes use of \a delete are candidates for
+ QScopedPointer usage(and if not, possibly another type of smart pointer
+ such as QSharedPointer). QScopedPointer intentionally has no copy
+ constructor or assignment operator, such that ownership and lifetime is
+ clearly communicated.
+
+ The const qualification on a regular C++ pointer can also be expressed with
+ a QScopedPointer:

+
+ \note QScopedPointer does not work with arrays.

Finally, QPointer holds a pointer to a QObject-derived object, but
it does so weakly. QPointer is similar, in that behaviour, to
QWeakPointer: it does not allow you to prevent the object from
being destroyed. All you can do is query whether it has been
destroyed or not.
