Detailed Description▲
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[]
}Member Function Documentation▲
QScopedArrayPointer::QScopedArrayPointer()▲
Constructs a QScopedArrayPointer instance.
[explicit] QScopedArrayPointer::QScopedArrayPointer(D *p)▲
Constructs a QScopedArrayPointer and stores the array of objects pointed to by p.
T &QScopedArrayPointer::operator[](qsizetype i)▲
Provides access to entry i of the scoped pointer's array of objects.
If the contained pointer is nullptr, behavior is undefined.
In Qt versions prior to 6.5, i was of type int, not qsizetype, possibly causing truncation on 64-bit platforms.
