Is there a memory leak in QByteArray?

Question

Qt

Judging by the code, QByteArray contains a pointer where the bytes are stored. And the destructor is created standard, that is, when QByteArray is deleted, the pointer is deleted, but the memory to which it points is not released?

Answer 1

No.
The QByteArray data pointer (data() method) is valid until the object is reallocated or deleted.
