Detailed Description

Function Documentation

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

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).

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

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).
