Obsolete Members for QtLiterals

以下成员源于类 QtLiterals 被弃用。 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。

函数

(deprecated (6.8)) QByteArray	operator""_qba (const char * str , size_t size )
(deprecated (6.8)) QString	operator""_qs (const char16_t * str , size_t size )

函数文档编制

[noexcept, since 6.2] 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。

另请参阅 QByteArrayLiteral and QtLiterals::operator""_qs (const char16_t *str, size_t size).

[noexcept, since 6.2] QString operator""_qs (const char16_t * str , size_t size )

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

使用 _s from Qt::StringLiterals namespace instead.

文字运算符创建的 QString out of the first size characters in the char16_t string literal str .

The QString 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 QStringLiteral , but saves typing when many string literals are present in the code.

以下代码创建 QString :

auto str = u"hello"_qs;
					

该函数在 Qt 6.2 引入。
