[noexcept, since 6.2, deprecated in 6.8] QByteArray operator""_qba (const char * str , size_t size )

This function is deprecated since 6.8. We strongly advise against using it in new code.

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。
