使用
_ba
from Qt::StringLiterals namespace instead.
文字运算符创建的 QByteArray out of the first size characters in the char string literal str .
The QByteArray is created at compile time, and the generated string data is stored in the read-only segment of the compiled object file. Duplicate literals may share the same read-only memory. This functionality is interchangeable with QByteArrayLiteral , but saves typing when many string literals are present in the code.
以下代码创建 QByteArray :
auto str = "hello"_qba;
该函数在 Qt 6.2 引入。
