以下成员源于类 QByteArray 已过时。 提供它们是为使旧源代码能继续工作。强烈建议不要在新代码中使用它们。

operator const char * () const |
(obsolete)

operator const void * () const |
Returns a pointer to the data stored in the byte array. The pointer can be used to access the bytes that compose the array. The data is '\0'-terminated. The pointer remains valid as long as the array isn't reallocated or destroyed.
This operator is mostly useful to pass a byte array to a function that accepts a
const char *
.
可以禁用此运算符通过定义
QT_NO_CAST_FROM_BYTEARRAY
当编译应用程序时。
注意：
QByteArray
可以存储任何字节值 (包括 \0)，但大多数函数需要
char *
自变量，假定数据在遇到首个 \0 时结束。
另请参阅 constData ().
