以下成員源於類 QByteArray 已過時。 提供它們是為使舊源代碼能繼續工作。強烈建議不要在新代碼中使用它們。

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 *
.
可以禁用此運算符通過定義
QT_NO_CAST_FROM_BYTEARRAY
當編譯應用程序時。
注意：
QByteArray
可以存儲任何字節值 (包括 \0)，但大多數函數需要
char *
自變量，假定數據在遇到首個 \0 時結束。
另請參閱 constData ().
