Function Documentation

[since 6.4] QLatin1StringView operator""_L1(const char *str, size_t size)

Literal operator that creates a QLatin1StringView out of the first size characters in the char string literal str.

The following code creates a QLatin1StringView:

using namespace Qt::Literals::StringLiterals;

auto str = "hello"_L1;

This function was introduced in Qt 6.4.

See also Qt::Literals::StringLiterals.

[since 6.4] QLatin1Char operator""_L1(char ch)

Literal operator that creates a QLatin1Char out of ch.

The following code creates a QLatin1Char:

using namespace Qt::Literals::StringLiterals;

auto ch = 'a'_L1;

This function was introduced in Qt 6.4.

See also Qt::Literals::StringLiterals.

[since 6.4] QByteArray operator""_ba(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:

using namespace Qt::Literals::StringLiterals;

auto str = "hello"_ba;

This function was introduced in Qt 6.4.

See also Qt::Literals::StringLiterals.

[since 6.4] QString operator""_s(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:

using namespace Qt::Literals::StringLiterals;

auto str = u"hello"_s;

This function was introduced in Qt 6.4.
