Obsolete Members for QtLiterals
The following members of class QtLiterals are deprecated. They are provided to keep old source code working. We strongly advise against using them in new code.
Functions
(since 6.2, deprecated in 6.8) QByteArray | operator""_qba(const char *str, size_t size) |
(since 6.2, deprecated in 6.8) QString | operator""_qs(const char16_t *str, size_t size) |
Function Documentation
[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.
Use _ba from Qt::StringLiterals namespace instead.
Literal operator that creates a 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.
The following code creates a QByteArray:
auto str = "hello"_qba;
This function was introduced in Qt 6.2.
See also QByteArrayLiteral and QtLiterals::operator""_qs(const char16_t *str, size_t size).
[noexcept, since 6.2, deprecated in 6.8] 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.
Use _s from Qt::StringLiterals namespace instead.
Literal operator that creates a 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.
The following code creates a QString:
auto str = u"hello"_qs;
This function was introduced in Qt 6.2.
See also QStringLiteral and QtLiterals::operator""_qba(const char *str, size_t size).
