Disables most automatic conversions from source literals and 8-bit data to unicode QStrings, but allows the use of the {QChar(char)} and {QString(const char (&ch)[N]} constructors, and the {QString::operator=(const char (&ch)[N])} assignment operator. This gives most of the type-safety benefits of \l QT_NO_CAST_FROM_ASCII but does not require user code to wrap character and string literals with QLatin1Char, QLatin1StringView or similar.
Using this macro together with source strings outside the 7-bit range, non-literals, or literals with embedded NUL characters is undefined.

\inmodule QtCore \reentrant
The QString class provides a Unicode character string.
QString stores a string of 16-bit \l{QChar}s, where each QChar corresponds to one UTF-16 code unit. (Unicode characters with code values above 65535 are stored using surrogate pairs, i.e., two consecutive \l{QChar}s.)
\l{Unicode} is an international standard that supports most of the writing systems in use today. It is a superset of US-ASCII (ANSI X3.4-1986) and Latin-1 (ISO 8859-1), and all the US-ASCII/Latin-1 characters are available at the same code positions.
Behind the scenes, QString uses \l{implicit sharing} (copy-on-write) to reduce memory usage and to avoid the needless copying of data. This also helps reduce the inherent overhead of storing 16-bit characters instead of 8-bit characters.
In addition to QString, Qt also provides the QByteArray class to store raw bytes and traditional 8-bit '\0'-terminated strings. For most purposes, QString is the class you want to use. It is used throughout the Qt API, and the Unicode support ensures that your applications will be easy to translate if you want to expand your application's market at some point. The two main cases where QByteArray is appropriate are when you need to store raw binary data, and when memory conservation is critical (like in embedded systems).
One way to initialize a QString is simply to pass a {const char } to its constructor. For example, the following code creates a QString of size 5 containing the data "Hello":
QString converts the {const char *} data into Unicode using the fromUtf8() function.
In all of the QString functions that take {const char *} parameters, the {const char *} is interpreted as a classic C-style '\0'-terminated string encoded in UTF-8. It is legal for the {const char *} parameter to be \nullptr.
You can also provide string data as an array of \l{QChar}s:
QString makes a deep copy of the QChar data, so you can modify it later without experiencing side effects. (If for performance reasons you don't want to take a deep copy of the character data, use QString::fromRawData() instead.)
Another approach is to set the size of the string using resize() and to initialize the data character per character. QString uses 0-based indexes, just like C++ arrays. To access the character at a particular index position, you can use \l operator[](). On non-{const} strings, \l operator[]() returns a reference to a character that can be used on the left side of an assignment. For example:
For read-only access, an alternative syntax is to use the at() function:
The at() function can be faster than \l operator[](), because it never causes a \l{deep copy} to occur. Alternatively, use the first(), last(), or sliced() functions to extract several characters at a time.
A QString can embed '\0' characters (QChar::Null). The size() function always returns the size of the whole string, including embedded '\0' characters.
After a call to the resize() function, newly allocated characters have undefined values. To set all the characters in the string to a particular value, use the fill() function.
QString provides dozens of overloads designed to simplify string usage. For example, if you want to compare a QString with a string literal, you can write code like this and it will work as expected:
You can also pass string literals to functions that take QStrings as arguments, invoking the QString(const char *) constructor. Similarly, you can pass a QString to a function that takes a {const char *} argument using the \l qPrintable() macro which returns the given QString as a {const char *}. This is equivalent to calling <QString>.toLocal8Bit().constData().
QString provides the following basic functions for modifying the character data: append(), prepend(), insert(), replace(), and remove(). For example:
In the above example the replace() function's first two arguments are the position from which to start replacing and the number of characters that should be replaced.
When data-modifying functions increase the size of the string, they may lead to reallocation of memory for the QString object. When this happens, QString expands by more than it immediately needs so as to have space for further expansion without reallocation until the size of the string has greatly increased.
The insert(), remove() and, when replacing a sub-string with one of different size, replace() functions can be slow (\l{linear time}) for large strings, because they require moving many characters in the string by at least one position in memory.
If you are building a QString gradually and know in advance approximately how many characters the QString will contain, you can call reserve(), asking QString to preallocate a certain amount of memory. You can also call capacity() to find out how much memory the QString actually has allocated.
QString provides \l{STL-style iterators} (QString::const_iterator and QString::iterator). In practice, iterators are handy when working with generic algorithms provided by the C++ standard library.
A frequent requirement is to remove whitespace characters from a string ('\n', '\t', ' ', etc.). If you want to remove whitespace from both ends of a QString, use the trimmed() function. If you want to remove whitespace from both ends and replace multiple consecutive whitespaces with a single space character within the string, use simplified().
If you want to find all occurrences of a particular character or substring in a QString, use the indexOf() or lastIndexOf() functions. The former searches forward starting from a given index position, the latter searches backward. Both return the index position of the character or substring if they find it; otherwise, they return -1. For example, here is a typical loop that finds all occurrences of a particular substring:
QString provides many functions for converting numbers into strings and strings into numbers. See the arg() functions, the setNum() functions, the number() static functions, and the toInt(), toDouble(), and similar functions.
To get an upper- or lowercase version of a string use toUpper() or toLower().
Lists of strings are handled by the QStringList class. You can split a string into a list of strings using the split() function, and join a list of strings into a single string with an optional separator using QStringList::join(). You can obtain a list of strings from a string list that contain a particular substring or that match a particular QRegularExpression using the QStringList::filter() function.
If you want to see if a QString starts or ends with a particular substring use startsWith() or endsWith(). If you simply want to check whether a QString contains a particular character or substring, use the contains() function. If you want to find out how many times a particular character or substring occurs in the string, use count().
To obtain a pointer to the actual character data, call data() or constData(). These functions return a pointer to the beginning of the QChar data. The pointer is guaranteed to remain valid until a non-{const} function is called on the QString.
QStrings can be compared using overloaded operators such as \l operator<(), \l operator<=(), \l operator==(), \l operator>=(), and so on. Note that the comparison is based exclusively on the numeric Unicode values of the characters. It is very fast, but is not what a human would expect; the QString::localeAwareCompare() function is usually a better choice for sorting user-interface strings, when such a comparison is available.
On Unix-like platforms (including Linux, \macos and iOS), when Qt is linked with the ICU library (which it usually is), its locale-aware sorting is used. Otherwise, on \macos and iOS, \l localeAwareCompare() compares according the "Order for sorted
lists" setting in the International preferences panel. On other Unix-like systems without ICU, the comparison falls back to the system library's strcoll(),
QString provides the following three functions that return a {const char *} version of the string as QByteArray: toUtf8(), toLatin1(), and toLocal8Bit().
\list
To convert from one of these encodings, QString provides fromLatin1(), fromUtf8(), and fromLocal8Bit(). Other encodings are supported through the QStringEncoder and QStringDecoder classes.
As mentioned above, QString provides a lot of functions and operators that make it easy to interoperate with {const char *} strings. But this functionality is a double-edged sword: It makes QString more convenient to use if all strings are US-ASCII or Latin-1, but there is always the risk that an implicit conversion from or to {const char *} is done using the wrong 8-bit encoding. To minimize these risks, you can turn off these implicit conversions by defining some of the following preprocessor symbols:
\list
You then need to explicitly call fromUtf8(), fromLatin1(), or fromLocal8Bit() to construct a QString from an 8-bit string, or use the lightweight QLatin1StringView class, for example:
Similarly, you must call toLatin1(), toUtf8(), or toLocal8Bit() explicitly to convert the QString to an 8-bit string.
\table 100 % \header
\row
The result variable, is a normal variable allocated on the stack. When return is called, and because we're returning by value, the copy constructor is called and a copy of the string is returned. No actual copying takes place thanks to the implicit sharing.
\endtable
For historical reasons, QString distinguishes between a null string and an empty string. A null string is a string that is initialized using QString's default constructor or by passing ({const char *})0 to the constructor. An empty string is any string with size 0. A null string is always empty, but an empty string isn't necessarily null:
All functions except isNull() treat null strings the same as empty strings. For example, toUtf8().constData() returns a valid pointer (not nullptr) to a '\0' character for a null string. We recommend that you always use the isEmpty() function and avoid isNull().
When a QString::arg() {''} format specifier includes the {'L'} locale qualifier, and the base is ten (its default), the default locale is used. This can be set using \l{QLocale::setDefault()}. For more refined control of localized string representations of numbers, see QLocale::toString(). All other number formatting done by QString follows the C locale's representation of numbers.
When QString::arg() applies left-padding to numbers, the fill character {'0'} is treated specially. If the number is negative, its minus sign will appear before the zero-padding. If the field is localized, the locale-appropriate zero character is used in place of {'0'}. For floating-point numbers, this special treatment only applies if the number is finite.
In member functions (e.g., arg(), number()) that represent floating-point numbers (float or double) as strings, the form of display can be controlled by a choice of format and precision, whose meanings are as for \l {QLocale::toString(double, char, int)}.
If the selected format includes an exponent, localized forms follow the locale's convention on digits in the exponent. For non-localized formatting, the exponent shows its sign and includes at least two digits, left-padding with zero if needed.
Many strings are known at compile time. The QString constructor from C++ string literals will copy the contents of the string, treating the contents as UTF-8. This requires a memory allocation and the re-encoding of the string data, operations that will happen at runtime. If the string data is known at compile time, you can use the QStringLiteral macro or similarly {operator""_s} to create QString's payload at compile time instead.
Using the QString {'+'} operator, it is easy to construct a complex string from multiple substrings. You will often write code like this:
There is nothing wrong with either of these string constructions, but there are a few hidden inefficiencies. Beginning with Qt 4.6, you can eliminate them.
First, multiple uses of the {'+'} operator usually means multiple memory allocations. When concatenating {n} substrings, where {n > 2}, there can be as many as {n - 1} calls to the memory allocator.
In 4.6, an internal template class {QStringBuilder} has been added along with a few helper functions. This class is marked internal and does not appear in the documentation, because you aren't meant to instantiate it in your code. Its use will be automatic, as described below. The class is found in {src/corelib/tools/qstringbuilder.cpp} if you want to have a look at it.
{QStringBuilder} uses expression templates and reimplements the {''} operator so that when you use {''} for string concatenation instead of {'+'}, multiple substring concatenations will be postponed until the final result is about to be assigned to a QString. At this point, the amount of memory required for the final result is known. The memory allocator is then called {once} to get the required space, and the substrings are copied into it one by one.
Additional efficiency is gained by inlining and reduced reference counting (the QString created from a {QStringBuilder} has a ref count of 1, whereas QString::append() needs an extra test).
There are two ways you can access this improved method of string construction. The straightforward way is to include {QStringBuilder} wherever you want to use it, and use the {''} operator instead of {'+'} when concatenating strings:
A more global approach, which is more convenient but not entirely source compatible, is to define QT_USE_QSTRINGBUILDER (by adding it to the compiler flags) at build time. This will make concatenating strings with {'+'} work the same way as {QStringBuilder} {''}.
auto keyword) with the result of string concatenation when QStringBuilder is enabled will show that the concatenation is indeed an object of a QStringBuilder specialization:This does not cause any harm, as QStringBuilder will implictly convert to QString when required. If this is undesirable, then one should specify the required types instead of having the compiler deduce them:
The maximum size of QString depends on the architecture. Most 64-bit systems can allocate more than 2 GB of memory, with a typical limit of 2^63 bytes. The actual value also depends on the overhead required for managing the data block. As a result, you can expect the maximum size of 2 GB minus overhead on 32-bit platforms, and 2^63 bytes minus overhead on 64-bit platforms. The number of elements that can be stored in a QString is this maximum size divided by the size of QChar.
When memory allocation fails, QString throws a std::bad_alloc exception if the application was compiled with exception support. Out of memory conditions in Qt containers are the only case where Qt will throw exceptions. If exceptions are disabled, then running out of memory is undefined behavior.
Note that the operating system may impose further limits on applications holding a lot of allocated memory, especially large, contiguous blocks. Such considerations, the configuration of such behavior or any mitigation are outside the scope of the Qt API.

The append() function is typically very fast (\l{constant time}), because QString preallocates extra space at the end of the string data so it can grow without reallocating the entire string each time.

Replaces occurrences of {N} in this string with the corresponding argument from args. The arguments are not positional: the first of the args replaces the {N} with the lowest {N} (all of them), the second of the args the {N} with the next-lowest {N} etc.
Args can consist of anything that implicitly converts to QString, QStringView or QLatin1StringView.
In addition, the following types are also supported: QChar, QLatin1Char.

Returns a copy of this string with the lowest numbered place marker replaced by string a, i.e., %1, %2, ..., %99.
fieldWidth specifies the minimum amount of space that argument a shall occupy. If a requires less space than fieldWidth, it is padded to fieldWidth with character fillChar. A positive fieldWidth produces right-aligned text. A negative fieldWidth produces left-aligned text.
This example shows how we might create a status string for reporting progress while processing a list of files:
First, arg(i) replaces %1. Then arg(total) replaces %2. Finally, arg(fileName) replaces %3.
One advantage of using arg() over asprintf() is that the order of the numbered place markers can change, if the application's strings are translated into other languages, but each arg() will still replace the lowest numbered unreplaced place marker, no matter where it appears. Also, if place marker i appears more than once in the string, the arg() replaces all of them.
If there is no unreplaced place marker remaining, a warning message is output and the result is undefined. Place marker numbers must be in the range 1 to 99.

Safely builds a formatted string from the format string cformat and an arbitrary list of arguments.
The format string supports the conversion specifiers, length modifiers, and flags provided by printf() in the standard C++ library. The cformat string and {s} arguments must be UTF-8 encoded.
char16_t, or ushort (as returned by QChar::unicode()). The char16_t, or ushort (as returned by QString::utf16()). This is at odds with the printf() in the standard C++ library, which defines {lc} to print a wchar_t and {wchar_t} is not 16 bits.For \l {QObject::tr()}{translations}, especially if the strings contains more than one escape sequence, you should consider using the arg() function instead. This allows the order of the replacements to be controlled by the translator.

Returns a pointer to the data stored in the QString.
The pointer can be used to access and modify the characters that compose the string.
Unlike constData() and unicode(), the returned data is always '\0'-terminated.
Example:
Note that the pointer remains valid only as long as the string is not modified by other means. For read-only access, constData() is faster because it never causes a \l{deep copy} to occur.

Here is the call graph for this function:Constructs a QString that uses the first size Unicode characters in the array unicode.
The data in unicode is not copied. The caller must be able to guarantee that unicode will not be deleted or modified as long as the QString (or an unmodified copy of it) exists.
Any attempts to modify the QString or copies of it will cause it to create a deep copy of the data, ensuring that the raw data isn't modified.
Here is an example of how we can use a QRegularExpression on raw data in memory without requiring to copy the data into a QString:

Here is the call graph for this function: Here is the caller graph for this function:Returns a QString initialized with the first size bytes of the UTF-8 string str.
If size is {-1}, {strlen(str)} is used instead.
UTF-8 is a Unicode codec and can represent all characters in a Unicode string like QString. However, invalid sequences are possible with UTF-8 and, if any such are found, they will be replaced with one or more "replacement characters", or suppressed. These include non-Unicode sequences, non-characters, overlong sequences or surrogate codepoints encoded into UTF-8.
This function can be used to process incoming data incrementally as long as all UTF-8 characters are terminated within the incoming data. Any unterminated characters at the end of the string will be replaced or suppressed. In order to do stateful decoding, please use \l QStringDecoder.

| bool QString::isLower | ( | ) | const |
Returns true if the string is lowercase, that is, it's identical to its toLower() folding.
Note that this does not mean that the string does not contain uppercase letters (some uppercase letters do not have a lowercase folding; they are left unchanged by toLower()). For more information, refer to the Unicode standard, section 3.13.

Returns true if this string is null; otherwise returns false.
Example:
Qt makes a distinction between null strings and empty strings for historical reasons. For most applications, what matters is whether or not a string contains any data, and this can be determined using the isEmpty() function.

Returns a string equivalent of the number n according to the specified base.
The base is 10 by default and must be between 2 and 36. For bases other than 10, n is treated as an unsigned integer.
The formatting always uses QLocale::C, i.e., English/UnitedStates. To get a localized string representation of a number, use QLocale::toString() with the appropriate locale.

Here is the call graph for this function:Ensures the string has space for at least size characters.
If you know in advance how large the string will be, you can call this function to save repeated reallocation in the course of building it. This can improve performance when building a string incrementally. A long sequence of operations that add to a string may trigger several reallocations, the last of which may leave you with significantly more space than you really need, which is less efficient than doing a single allocation of the right size at the start.
If in doubt about how much space shall be needed, it is usually better to use an upper bound as size, or a high estimate of the most likely size, if a strict upper bound would be much bigger than this. If size is an underestimate, the string will grow as needed once the reserved size is exceeded, which may lead to a larger allocation than your best overestimate would have and will slow the operation that triggers it.
This function is useful for code that needs to build up a long string and wants to avoid repeated reallocation. In this example, we want to add to the string until some condition is true, and we're fairly sure that size is large enough to make a call to reserve() worthwhile:

If size is greater than the current size, the string is extended to make it size characters long with the extra characters added to the end. The new characters are uninitialized.
If size is less than the current size, characters beyond position size are excluded from the string.
Example:
If you want to append a certain number of identical characters to the string, use the \l {QString::}{resize(qsizetype, QChar)} overload.
If you want to expand the string so that it reaches a certain width and fill the new positions with a particular character, use the leftJustified() function:
If size is negative, it is equivalent to passing zero.

This function returns a section of the string.
This string is treated as a sequence of fields separated by the character, sep. The returned string consists of the fields from position start to position end inclusive. If end is not specified, all fields from position start to the end of the string are included. Fields are numbered 0, 1, 2, etc., counting from the left, and -1, -2, etc., counting from right to left.
The flags argument can be used to affect some aspects of the function's behavior, e.g. whether to be case sensitive, whether to skip empty fields and how to deal with leading and trailing separators; see \l{SectionFlags}.
If start or end is negative, we count fields from the right of the string, the right-most field being -1, the one from right-most field being -2, and so on.

Splits the string into substrings wherever sep occurs, and returns the list of those strings.
If sep does not match anywhere in the string, split() returns a single-element list containing this string.
cs specifies whether sep should be matched case sensitively or case insensitively.
If behavior is Qt::SkipEmptyParts, empty entries don't appear in the result. By default, empty entries are kept.
Example:
If sep is empty, split() returns an empty string, followed by each of the string's characters, followed by another empty string:
To understand this behavior, recall that the empty string matches everywhere, so the above is qualitatively the same as:

The std::wstring is encoded in utf16 on platforms where wchar_t is 2 bytes wide (e.g. windows) and in ucs4 on platforms where wchar_t is 4 bytes wide (most Unix systems).
This method is mostly useful to pass a QString to a function that accepts a std::wstring object.

Here is the call graph for this function: Here is the caller graph for this function:Returns a UCS-4/UTF-32 representation of the string as a QList<uint>.
UCS-4 is a Unicode codec and therefore it is lossless. All characters from this string will be encoded in UCS-4. Any invalid sequence of code units in this string is replaced by the Unicode's replacement character (QChar::ReplacementCharacter, which corresponds to {U+FFFD}).
The returned list is not \0'-terminated.

\macro QStringLiteral(str)
The macro generates the data for a QString out of the string literal str at compile time. Creating a QString from it is free in this case, and the generated string data is stored in the read-only segment of the compiled object file.
If you have code that looks like this:
then a temporary QString will be created to be passed as the {hasAttribute} function parameter. This can be quite expensive, as it involves a memory allocation and the copy/conversion of the data into QString's internal encoding.
This cost can be avoided by using QStringLiteral instead:
In this case, QString's internal data will be generated at compile time; no conversion or allocation will occur at runtime.
Using QStringLiteral instead of a double quoted plain C++ string literal can significantly speed up creation of QString instances from data known at compile time.
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:
