Detailed Description
The QScopedArrayPointer class stores a pointer to a dynamically allocated array of objects, and deletes it upon destruction.
A QScopedArrayPointer is a QScopedPointer that defaults to deleting the object it is pointing to with the delete[] operator. It also features operator[] for convenience, so we can write:
void foo()
{
QScopedArrayPointer<int> i(new int[10]);
i[2] = 42;
...
return; // our integer array is now deleted using delete[]

QScopedArrayPointer::QScopedArrayPointer()
Constructs a QScopedArrayPointer instance.
T &QScopedArrayPointer::operator[](int i)
Provides access to entry i of the scoped pointer's array of objects.
If the contained pointer is null, behavior is undefined.

const T &QScopedArrayPointer::operator[](int i) const
Provides access to entry i of the scoped pointer's array of objects.
