+
+        Otherwise, when we are doing the actual compile phase, check to see

+        makes it possible to reduce greatly the stack usage in pcre2_match(). If
+        the group is preceded by OP_BRAZERO, convert this to OP_BRAPOSZERO.
+
+        Then, if the minimum number of matches is 1 or 0, cancel the possessive
+        flag so that the default action below, of wrapping everything inside
+        atomic brackets, does not happen. When the minimum is greater than 1,

-****************************************************************************
-                   RECURSION IN THE match() FUNCTION
-
-The match() function is highly recursive, though not every recursive call
-increases the recursion depth. Nevertheless, some regular expressions can cause
-it to recurse to a great depth. I was writing for Unix, so I just let it call
-itself recursively. This uses the stack for saving everything that has to be
-saved for a recursive call. On Unix, the stack can be large, and this works
-fine.
-
-It turns out that on some non-Unix-like systems there are problems with
-programs that use a lot of stack. (This despite the fact that every last chip
-has oodles of memory these days, and techniques for extending the stack have
-been known for decades.) So....
-
-There is a fudge, triggered by defining HEAP_MATCH_RECURSE, which avoids
-recursive calls by keeping local variables that need to be preserved in blocks
-of memory on the heap instead instead of on the stack. Macros are used to
-achieve this so that the actual code doesn't look very different to what it
-always used to.
-
-The original heap-recursive code used longjmp(). However, it seems that this
-can be very slow on some operating systems. Following a suggestion from Stan
-Switzer, the use of longjmp() has been abolished, at the cost of having to
-provide a unique number for each call to RMATCH. There is no way of generating
-a sequence of numbers at compile time in C. I have given them names, to make
-them stand out more clearly.
-
-Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
-FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
-tests. Furthermore, not using longjmp() means that local dynamic variables
-don't have indeterminate values; this has meant that the frame size can be
-reduced because the result can be "passed back" by straight setting of the
-variable instead of being passed in the frame.

+                   "Recursion" in the match() function
 
+The original match() function was highly recursive, but this proved to be the
+source of a number of problems over the years, mostly because of the relatively
+small system stacks that are commonly found. As new features were added to
+patterns, various kludges were invented to reduce the amount of stack used,
+making the code hard to understand in places.
 
-/* When HEAP_MATCH_RECURSE is not defined, the match() function implements
-backtrack points by calling itself recursively in all but one case. The one
-special case is when processing OP_RECURSE, which specifies recursion in the
-pattern. The entire ovector must be saved and restored while processing
-OP_RECURSE. If the ovector is small enough, instead of calling match()
-directly, op_recurse_ovecsave() is called. This function uses the system stack
-to save the ovector while calling match() to process the pattern recursion. */
+A version did exist that used individual frames on the heap instead of calling
+match() recursively, but this ran substantially slower. The current version is
+a refactoring that uses a vector of frames to remember backtracking points.
+This runs no slower, and possibly even a bit faster than the original recursive
+implementation. An initial vector of size START_FRAMES_SIZE (enough for maybe
+50 frames) is allocated on the system stack. If this is not big enough, the
+heap is used for a larger vector.

-/* When this function is called, mb->recursive has already been updated to
-point to a new recursion data block, and all its fields other than ovec_save
-have been set.
-
-This function exists so that the local vector variable ovecsave is no longer
-defined in the match() function, as it was in PCRE1. It is used only when there
-is recursion in the pattern, so it wastes a lot of stack to have it defined for
-every call of match(). We now use this function as an indirect way of calling
-match() only in the case when ovecsave is needed. (David Wheeler used to say
-"All problems in computer science can be solved by another level of
-indirection.")
-
-HOWEVER: when this file is compiled by gcc in an optimizing mode, because this
-function is called only once, and only from within match(), gcc will "inline"
-it - that is, move it inside match() - and this completely negates its reason
-for existence. Therefore, we mark it as non-inline when gcc is in use.
+/* These macros pack up tests that are used for partial matching several times
+in the code. We set the "hit end" flag if the pointer is at the end of the
+subject and also past the earliest inspected character (i.e. something has been
+matched, even if not part of the actual matched string). For hard partial
+matching, we then return immediately. The second one is used when we already
+know we are past the end of the subject. */

-  is either scratch register or saved register, SLJIT allows accessing
-  them from the other set. For example, four registers can be used as
-  scratch registers and the fifth one as saved register on the architecture
-  above. Of course the last two scratch registers (R2 and R3) from this
-  four will be saved on the stack, because they are defined as saved

-  used for referencing to these registers instead of S2 and S1, which
-  makes easier to write platform independent code. Scratch registers
-  can be saved registers in a similar way, but these extra saved
-  registers will not be preserved across function calls! Hence the

-  saved registers is too low. This can be done by copy them onto

+   of the input and the result registers are not defined by SLJIT, it might
+   be defined by the CPU architecture (e.g. MIPS). To satisfy these CPU
+   requirements all source registers must be the result of those operations
+   where this option was also set. Memory loads read 32 bit values rather
+   than 64 bit ones. In other words 32 bit and 64 bit operations cannot
+   be mixed. The only exception is SLJIT_MOV32 and SLJIT_MOVU32 whose source
+   register can hold any 32 or 64 bit value, and it is converted to a 32 bit
+   compatible format first. This conversion is free (no instructions are
+   emitted) on most CPUs. A 32 bit value can also be coverted to a 64 bit
+   value by SLJIT_MOV_S32 (sign extension) or SLJIT_MOV_U32 (zero extension).
+
+   Note: memory addressing always uses 64 bit values on 64 bit systems so
+         the result of a 32 bit operation must not be used with SLJIT_MEMx
+         macros.
+
+   This option is part of the instruction name, so there is no need to
+   manually set it. E.g:

+/* Many CPUs (x86, ARM, PPC) has status flags which can be set according
+   to the result of an operation. Other CPUs (MIPS) does not have status
+   flags, and results must be stored in registers. To cover both architecture
+   types efficiently only two flags are defined by SLJIT:
+
+    * Zero (equal) flag: it is set if the result is zero
+    * Variable flag: its value is defined by the last arithmetic operation
+
+   SLJIT instructions can set any or both of these flags. The value of
+   these flags is undefined if the instruction does not specify their value.
+   The description of each instruction contains the list of allowed flag
+   types.
+
+   Example: SLJIT_ADD can set the Z, OVERFLOW, CARRY flags hence
+
+     sljit_op2(..., SLJIT_ADD, ...)
+       Both the zero and variable flags are undefined so they can
+       have any value after the operation is completed.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+       Sets the zero flag if the result is zero, clears it otherwise.
+       The variable flag is undefined.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_OVERFLOW, ...)
+       Sets the variable flag if an integer overflow occurs, clears
+       it otherwise. The zero flag is undefined.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z | SLJIT_SET_CARRY, ...)
+       Sets the zero flag if the result is zero, clears it otherwise.
+       Sets the variable flag if unsigned overflow (carry) occurs,
+       clears it otherwise.
+
+   If an instruction (e.g. SLJIT_MOV) does not modify flags the flags are
+   unchanged.
+
+   Using these flags can reduce the number of emitted instructions. E.g. a
+   fast loop can be implemented by decreasing a counter register and set the
+   zero flag to jump back if the counter register is not reached zero.
+
+   Motivation: although CPUs can set a large number of flags, usually their
+   values are ignored or only one of them is used. Emulating a large number
+   of flags on systems without flag register is complicated so SLJIT
+   instructions must specify the flag they want to use and only that flag
+   will be emulated. The last arithmetic instruction can be repeated if
+   multiple flags needs to be checked.

+
+   Register arguments and base registers can only be used once for move

+   mode must also be 0. Reason: SLJIT_MOVU instructions are expected to
+   be in high-performance loops where complex instruction emulation
+   would be too costly.
+
+   Examples for invalid move with update instructions:
+
+   sljit_emit_op1(..., SLJIT_MOVU_U8,
+       SLJIT_R0, 0, SLJIT_MEM1(SLJIT_R0), 8);
+   sljit_emit_op1(..., SLJIT_MOVU_U8,

+   sljit_emit_op1(..., SLJIT_MOVU_U8,
+       SLJIT_MEM2(SLJIT_R0, SLJIT_R1), 0, SLJIT_MEM1(SLJIT_R0), 8);
+   sljit_emit_op1(..., SLJIT_MOVU_U8,
+       SLJIT_MEM2(SLJIT_R0, SLJIT_R1), 0, SLJIT_MEM2(SLJIT_R1, SLJIT_R0), 0);
+   sljit_emit_op1(..., SLJIT_MOVU_U8,
+       SLJIT_R2, 0, SLJIT_MEM2(SLJIT_R0, SLJIT_R1), 1);
+
+   The following example is valid, since only the offset register is
+   used multiple times:
+
+   sljit_emit_op1(..., SLJIT_MOVU_U8,
+       SLJIT_MEM2(SLJIT_R0, SLJIT_R2), 0, SLJIT_MEM2(SLJIT_R1, SLJIT_R2), 0);
+
+   If the destination of a MOV without update instruction is SLJIT_UNUSED
+   and the source operand is a memory address the compiler emits a prefetch
+   instruction if this instruction is supported by the current CPU.
+   Higher data sizes bring the data closer to the core: a MOV with word
+   size loads the data into a higher level cache than a byte size. Otherwise
+   the type does not affect the prefetch instruction. Furthermore a prefetch
+   instruction never fails, so it can be used to prefetch a data from an
+   address and check whether that address is NULL afterwards.

     signal, Qt provides the QObject::sender() function, which returns
     a pointer to the object that sent the signal.
 
-    The QSignalMapper class is provided for situations where many
-    signals are connected to the same slot and the slot needs to
-    handle each signal differently.
+    Lambda expressions are a convenient way to pass custom arguments to a slot:
 
-    Suppose you have three push buttons that determine which file you
-    will open: "Tax File", "Accounts File", or "Report File".
-
-    In order to open the correct file, you use QSignalMapper::setMapping() to
-    map all the QPushButton::clicked() signals to a QSignalMapper object. Then you connect
-    the file's QPushButton::clicked() signal to the QSignalMapper::map() slot.
-
-    \snippet signalmapper/filereader.cpp 0
-
-    Then, you connect the \l{QSignalMapper::}{mapped()} signal to
-    \c{readFile()} where a different file will be opened, depending on
-    which push button is pressed.

+    \class QRandomGenerator
+    \inmodule QtCore
+    \since 5.10
+
+    \brief The QRandomGenerator class allows one to obtain random values from a
+    high-quality, seed-less Random Number Generator.
+
+    QRandomGenerator may be used to generate random values from a high-quality
+    random number generator. Unlike qrand(), QRandomGenerator does not need to be
+    seeded. That also means it is not possible to force it to produce a
+    reliable sequence, which may be needed for debugging.
+
+    The class can generate 32-bit or 64-bit quantities, or fill an array of
+    those. The most common way of generating new values is to call the get32(),
+    get64() or fillRange() functions. One would use it as:
+
+    \code
+        quint32 value = QRandomGenerator::get32();
+    \endcode
+
+    Additionally, it provides a floating-point function getReal() that returns
+    a number in the range [0, 1) (that is, inclusive of zero and exclusive of
+    1). There's also a set of convenience functions that facilitate obtaining a
+    random number in a bounded, integral range.
+
+    \warning This class is not suitable for bulk data creation. See below for the
+    technical reasons.
+
+    \section1 Frequency and entropy exhaustion
+
+    QRandomGenerator does not need to be seeded and instead uses operating system
+    or hardware facilities to generate random numbers. On some systems and with
+    certain hardware, those facilities are true Random Number Generators.
+    However, if they are true RNGs, those facilities have finite entropy source
+    and thus may fail to produce any results if the entropy pool is exhausted.
+
+    If that happens, first the operating system then QRandomGenerator will fall
+    back to Pseudo Random Number Generators of decreasing qualities (Qt's
+    fallback generator being the simplest). Therefore, QRandomGenerator should
+    not be used for high-frequency random number generation, lest the entropy
+    pool become empty. As a rule of thumb, this class should not be called upon
+    to generate more than a kilobyte per second of random data (note: this may
+    vary from system to system).
+
+    If an application needs true RNG data in bulk, it should use the operating
+    system facilities (such as \c{/dev/random} on Unix systems) directly and
+    wait for entropy to become available. If true RNG is not required,
+    applications should instead use a PRNG engines and can use QRandomGenerator to
+    seed those.
+
+    \section1 Standard C++ Library compatibility
+
+    QRandomGenerator is modeled after
+    \c{\l{http://en.cppreference.com/w/cpp/numeric/random/random_device}{std::random_device}}
+    and may be used in almost all contexts that the Standard Library can.
+    QRandomGenerator attempts to use either the same engine that backs
+    \c{std::random_device} or a better one. Note that \c{std::random_device} is
+    also allowed to fail if the source entropy pool becomes exhausted, in which
+    case it will throw an exception. QRandomGenerator never throws, but may abort
+    program execution instead.
+
+    Like the Standard Library class, QRandomGenerator can be used to seed Standard
+    Library deterministic random engines from \c{<random>}, such as the
+    Mersenne Twister. Unlike \c{std::random_device}, QRandomGenerator also
+    implements the API of
+    \c{\l{http://en.cppreference.com/w/cpp/numeric/random/seed_seq}{std::seed_seq}},
+    allowing it to seed the deterministic engines directly.
+
+    The following code can be used to create and seed the
+    implementation-defined default deterministic PRNG, then use it to fill a
+    block range:
+
+    \code
+        QRandomGenerator rd;
+        std::default_random_engine rng(rd);
+        std::generate(block.begin(), block.end(), rng);
+
+        // equivalent to:
+        for (auto &v : block)
+            v = rng();
+    \endcode
+
+    QRandomGenerator is also compatible with the uniform distribution classes
+    \c{std::uniform_int_distribution} and \c{std:uniform_real_distribution}, as
+    well as the free function \c{std::generate_canonical}. For example, the
+    following code may be used to generate a floating-point number in the range
+    [1, 2.5):
+
+    \code
+        QRandomGenerator64 rd;
+        std::uniform_real_distribution dist(1, 2.5);
+        return dist(rd);
+    \endcode
+
+    Note the use of the QRandomGenerator64 class instead of QRandomGenerator to
+    obtain 64 bits of random data in a single call, though it is not required
+    to make the algorithm work (the Standard Library functions will make as
+    many calls as required to obtain enough bits of random data for the desired
+    range).

+    \brief The QRandomGenerator64 class allows one to obtain 64-bit random values
+    from a high-quality, seed-less Random Number Generator.
+
+    QRandomGenerator64 is a simple adaptor class around QRandomGenerator, making the
+    QRandomGenerator::get64() function the default for operator()(), instead of the
+    function that returns 32-bit quantities. This class is intended to be used
+    in conjunction with Standard Library algorithms that need 64-bit quantities
+    instead of 32-bit ones.
+
+    In all other aspects, the class is the same. Please refer to
+    QRandomGenerator's documentation for more information.

-    \class QWinOverlappedIoNotifier
-    \inmodule QtCore
-    \brief The QWinOverlappedIoNotifier class provides support for overlapped I/O notifications on Windows.
-    \since 5.0
-    \internal
-
-    The QWinOverlappedIoNotifier class makes it possible to use efficient
-    overlapped (asynchronous) I/O notifications on Windows by using an
-    I/O completion port.
-
-    Once you have obtained a file handle, you can use setHandle() to get
-    notifications for I/O operations. Whenever an I/O operation completes,
-    the notified() signal is emitted which will pass the number of transferred
-    bytes, the operation's error code and a pointer to the operation's
-    OVERLAPPED object to the receiver.
-
-    Every handle that supports overlapped I/O can be used by
-    QWinOverlappedIoNotifier. That includes file handles, TCP sockets
-    and named pipes.
-
-    Note that you must not use ReadFileEx() and WriteFileEx() together
-    with QWinOverlappedIoNotifier. They are not supported as they use a
-    different I/O notification mechanism.
-
-    The hEvent member in the OVERLAPPED structure passed to ReadFile()
-    or WriteFile() is ignored and can be used for other purposes.
-
-    \warning This class is only available on Windows.
-
-    Due to peculiarities of the Windows I/O completion port API, users of
-    QWinOverlappedIoNotifier must pay attention to the following restrictions:
-    \list
-    \li File handles with a QWinOverlappedIoNotifer are assigned to an I/O
-        completion port until the handle is closed. It is impossible to
-        disassociate the file handle from the I/O completion port.
-    \li There can be only one QWinOverlappedIoNotifer per file handle. Creating
-        another QWinOverlappedIoNotifier for that file, even with a duplicated
-        handle, will fail.
-    \li Certain Windows API functions are unavailable for file handles that are
-        assigned to an I/O completion port. This includes the functions
-        \c{ReadFileEx} and \c{WriteFileEx}.
-    \endlist
-    See also the remarks in the MSDN documentation for the
-    \c{CreateIoCompletionPort} function.

+    \class QSemaphoreReleaser
+    \brief The QSemaphoreReleaser class provides exception-safe deferral of a QSemaphore::release() call
+    \since 5.10
+    \ingroup thread
+    \inmodule QtCore
+
+    \reentrant
+
+    QSemaphoreReleaser can be used wherever you would otherwise use
+    QSemaphore::release(). Constructing a QSemaphoreReleaser defers the
+    release() call on the semaphore until the QSemaphoreReleaser is
+    destroyed (see
+    \l{http://en.cppreference.com/w/cpp/language/raii}{RAII pattern}).
+
+    You can use this to reliably release a semaphore to avoid dead-lock
+    in the face of exceptions or early returns:
+
+    \code
+    // ... do something that may throw or return early
+    sem.release();
+    \endcode
+
+    If an early return is taken or an exception is thrown before the
+    \c{sem.release()} call is reached, the semaphore is not released,
+    possibly preventing the thread waiting in the corresponding
+    \c{sem.acquire()} call from ever continuing execution.
+
+    When using RAII instead:
+
+    \code
+    const QSemaphoreReleaser releaser(sem);
+    // ... do something that may throw or early return
+    // implicitly calls sem.release() here and at every other return in between
+    \endcode
+
+    this can no longer happen, because the compiler will make sure that
+    the QSemaphoreReleaser destructor is always called, and therefore
+    the semaphore is always released.
+
+    QSemaphoreReleaser is move-enabled and can therefore be returned
+    from functions to transfer responsibility for releasing a semaphore
+    out of a function or a scope:
+
+    \code
+    { // some scope
+        QSemaphoreReleaser releaser; // does nothing
+        // ...
+        if (someCondition) {
+            releaser = QSemaphoreReleaser(sem);
+            // ...
+        }
+        // ...
+    } // conditionally calls sem.release(), depending on someCondition
+    \endcode
+
+    A QSemaphoreReleaser can be canceled by a call to cancel(). A canceled
+    semaphore releaser will no longer call QSemaphore::release() in its
+    destructor.

+
+    \a fieldWidth specifies the minimum amount of space that \a a
+    shall occupy. If \a a requires less space than \a fieldWidth, it
+    is padded to \a fieldWidth with character \a fillChar.  A positive

+
+    First, \c arg(i) replaces \c %1. Then \c arg(total) replaces \c
+    %2. Finally, \c arg(fileName) replaces \c %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 \c %i appears more than once in the
+    string, arg() replaces all of them.
+
+    If there is no unreplaced place-marker remaining, a warning message
+    is printed and the result is undefined. Place-marker numbers must be
+    in the range 1 to 99.

+
+    \a fieldWidth specifies the minimum amount of space that \a a
+    shall occupy. If \a a requires less space than \a fieldWidth, it
+    is padded to \a fieldWidth with character \a fillChar.  A positive
+    \a fieldWidth produces right-aligned text. A negative \a fieldWidth
+    produces left-aligned text.
+
+    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 \c %i appears more than once in the
+    string, arg() replaces all of them.
+
+    If there is no unreplaced place-marker remaining, a warning message
+    is printed and the result is undefined. Place-marker numbers must be
+    in the range 1 to 99.

+    \class QStringView
+    \inmodule QtCore
+    \since 5.10
+    \brief The QStringView class provides a unified view on UTF-16 strings with a read-only subset of the QString API.
+    \reentrant
+    \ingroup tools
+    \ingroup string-processing
+
+    A QStringView references a contiguous portion of a UTF-16 string it does
+    not own. It acts as an interface type to all kinds of UTF-16 string,
+    without the need to construct a QString first.
+
+    The UTF-16 string may be represented as an array (or an array-compatible
+    data-structure such as QString,
+    std::basic_string, etc.) of QChar, \c ushort, \c char16_t (on compilers that
+    support C++11 Unicode strings) or (on platforms, such as Windows,
+    where it is a 16-bit type) \c wchar_t.
+
+    QStringView is designed as an interface type; its main use-case is
+    as a function parameter type. When QStringViews are used as automatic
+    variables or data members, care must be taken to ensure that the referenced
+    string data (for example, owned by a QString) outlives the QStringView on all code paths,
+    lest the string view ends up referencing deleted data.
+
+    When used as an interface type, QStringView allows a single function to accept
+    a wide variety of UTF-16 string data sources. One function accepting QStringView
+    thus replaces three function overloads (taking QString, QStringRef, and
+    \c{(const QChar*, int)}), while at the same time enabling even more string data
+    sources to be passed to the function, such as \c{u"Hello World"}, a \c char16_t
+    string literal.
+
+    QStringViews should be passed by value, not by reference-to-const:
+    \code
+    void myfun1(QStringView sv);        // preferred
+    void myfun2(const QStringView &sv); // compiles and works, but slower
+    \endcode
+
+    If you want to give your users maximum freedom in what strings they can pass
+    to your function, accompany the QStringView overload with overloads for
+
+    \list
+        \li \e QChar: this overload can delegate to the QStringView version:
+            \code
+            void fun(QChar ch) { fun(QStringView(&ch, 1)); }
+            \endcode
+            even though, for technical reasons, QStringView cannot provide a
+            QChar constructor by itself.
+        \li \e QString: if you store an unmodified copy of the string and thus would
+            like to take advantage of QString's implicit sharing.
+        \li QLatin1String: if you can implement the function without converting the
+            QLatin1String to UTF-16 first; users expect a function overloaded on
+            QLatin1String to perform strictly less memory allocations than the
+            semantically equivalent call of the QStringView version, involving
+            construction of a QString from the QLatin1String.
+    \endlist
+
+    QStringView can also be used as the return value of a function. If you call a
+    function returning QStringView, take extra care to not keep the QStringView
+    around longer than the function promises to keep the referenced string data alive.
+    If in doubt, obtain a strong reference to the data by calling toString() to convert
+    the QStringView into a QString.
+
+    QStringView is a \e{Literal Type}, but since it stores data as \c{char16_t}, iteration
+    is not \c constexpr (casts from \c{const char16_t*} to \c{const QChar*}, which is not
+    allowed in \c constexpr functions). You can use an indexed loop and/or utf16() in
+    \c constexpr contexts instead.
+
+    \note We strongly discourage the use of QList<QStringView>,
+    because QList is a very inefficient container for QStringViews (it would heap-allocate
+    every element). Use QVector (or std::vector) to hold QStringViews instead.

+    \brief The QPlatformVulkanInstance class provides an abstraction for Vulkan instances.
+
+    The platform Vulkan instance is responsible for loading a Vulkan library,
+    resolving the basic entry points for creating instances, providing support
+    for creating new or adopting existing VkInstances, and abstracting some
+    WSI-specifics like checking if a given queue family can be used to present
+    using a given window.
+
+    \note platform plugins will typically subclass not this class, but rather
+    QBasicVulkanPlatformInstance.
+
+    \note Vulkan instance creation is split into two phases: a new
+    QPlatformVulkanInstance is expected to load the Vulkan library and do basic
+    initialization, after which the supported layers and extensions can be
+    queried. Everything else is deferred into createOrAdoptInstance().

+
+    \brief The QVulkanFunctions class provides cross-platform access to the
+    instance level core Vulkan 1.0 API.
+
+    Qt and Qt applications do not link to any Vulkan libraries by default.
+    Instead, all functions are resolved dynamically at run time. Each
+    QVulkanInstance provides a QVulkanFunctions object retrievable via
+    QVulkanInstance::functions(). This does not contain device level functions
+    in order to avoid the potential overhead of an internal dispatching.
+    Instead, functions that rely on a device, or a dispatchable child object of
+    a device, are exposed via QVulkanDeviceFunctions and
+    QVulkanInstance::deviceFunctions(). QVulkanFunctions and
+    QVulkanDeviceFunctions together provides access to the full core Vulkan
+    API, excluding any extensions.
+
+    \note QVulkanFunctions instances cannot be constructed directly.
+
+    The typical usage is the following:
+
+    \code
+    void Window::render()
+    {
+        QVulkanInstance *inst = vulkanInstance();
+        QVulkanFunctions *f = inst->functions();
+        ...
+        VkResult err = f->vkAllocateCommandBuffers(device, &cmdBufInfo, &cmdBuf);
+        ...
+    }
+    \endcode
+
+    \note Windowing system interface (WSI) specifics and extensions are
+    excluded. This class only covers core Vulkan commands, with the exception
+    of instance creation, destruction, and function resolving, since such
+    functionality is covered by QVulkanInstance itself.
+
+    To access additional functions, applications can use
+    QVulkanInstance::getInstanceProcAddr() and vkGetDeviceProcAddr().
+    Applications can also decide to link to a Vulkan library directly, as
+    platforms with an appropriate loader will typically export function symbols
+    for the core commands. See
+    \l{https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkGetInstanceProcAddr.html}{the

+    \class QVulkanInstance
+    \since 5.10
+    \inmodule QtGui
+
+    \brief The QVulkanInstance class represents a native Vulkan instance, enabling
+    Vulkan rendering onto a QSurface.
+
+    \l{https://www.khronos.org/vulkan/}{Vulkan} is a cross-platform, explicit
+    graphics and compute API. This class provides support for loading a Vulkan
+    library and creating an \c instance in a cross-platform manner. For an
+    introduction on Vulkan instances, refer
+    \l{https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.html#initialization-instances}{to
+    section 3.2 of the specification}.
+
+    \note Platform-specific support for Vulkan instances and windows with
+    Vulkan-capable surfaces is provided by the various platform plugins. Not
+    all of them will support Vulkan, however. When running on such a platform,
+    create() will fail and always return \c false.
+
+    \note Vulkan support may get automatically disabled for a given Qt build due
+    to not having the necessary Vulkan headers available at build time. When
+    this is the case, and the output of \c configure indicates Vulkan support is
+    disabled, the QVulkan* classes will be unavailable.
+
+    \note Some functions changed their signature between the various Vulkan
+    header revisions. When building Qt and only headers with the old,
+    conflicting signatures are present in a system, Vulkan support will get
+    disabled. It is recommended to use headers from Vulkan 1.0.39 or newer.
+
+    \section1 Initialization
+
+    Similarly to QOpenGLContext, any actual Vulkan instance creation happens
+    only when calling create(). This allows using QVulkanInstance as a plain
+    member variable while retaining control over when to perform
+    initialization.
+
+    Querying the supported instance-level layers and extensions is possible by
+    calling supportedLayers() and supportedExtensions(). These ensure the
+    Vulkan library is loaded, and can therefore be called safely before
+    create() as well.
+
+    Instances store per-application Vulkan state and creating a \c VkInstance
+    object initializes the Vulkan library. In practice there will typically be
+    a single instance constructed early on in main(). The object then stays
+    alive until exiting the application.
+
+    Every Vulkan-based QWindow must be associated with a QVulkanInstance by
+    calling QWindow::setVulkanInstance(). Thus a typical application pattern is
+    the following:
+
+    \code
+    int main(int argc, char **argv)
+    {
+        QGuiApplication app(argc, argv);
+
+        QVulkanInstance inst;
+        if (!inst.create())
+            return 1;
+
+        ...
+        window->setVulkanInstance(&inst);
+        window->show();
+
+        return app.exec();
+    }
+    \endcode
+
+    \section1 Configuration
+
+    QVulkanInstance automatically enables the minimum set of extensions it
+    needs on the newly created instance. In practice this means the
+    \c{VK_KHR_*_surface} family of extensions.
+
+    By default Vulkan debug output, for example messages from the validation
+    layers, is routed to qDebug(). This can be disabled by passing the flag
+    \c NoDebugOutputRedirect to setFlags() \e before invoking create().
+
+    To enable additional layers and extensions, provide the list via
+    setLayers() and setExtensions() \e before invoking create(). When a
+    given layer or extension is not reported as available from the instance,
+    the request is ignored. After a successful call to create(), the values
+    returned from functions like layers() and extensions() reflect the actual
+    enabled layers and extensions. When necessary, for example to avoid
+    requesting extensions that conflict and thus would fail the Vulkan instance
+    creation, the list of actually supported layers and extensions can be
+    examined via supportedLayers() and supportedExtensions() before calling
+    create().
+
+    For example, to enable the standard validation layers, one could do the
+    following:
+
+    \code
+        QVulkanInstance inst;
+
+        // Enable validation layer, if supported. Messages go to qDebug by default.
+        inst.setLayers(QByteArrayList() << "VK_LAYER_LUNARG_standard_validation");
+
+        bool ok = inst.create();
+        if (!ok)
+            ... // Vulkan not available
+        if (!inst.layers().contains("VK_LAYER_LUNARG_standard_validation"))
+            ... // validation layer not available
+    \endcode
+
+    Or, alternatively, to make decisions before attempting to create a Vulkan
+    instance:
+
+    \code
+        QVulkanInstance inst;
+
+        if (inst.supportedLayers().contains("VK_LAYER_LUNARG_standard_validation"))
+            ...
+
+        bool ok = inst.create();
+        ...
+    \endcode
+
+    \section1 Adopting an Existing Instance
+
+    By default QVulkanInstance creates a new Vulkan instance. When working with
+    external engines and renderers, this may sometimes not be desirable. When
+    there is a \c VkInstance handle already available, call setVkInstance()
+    before invoking create(). This way no additional instances will get
+    created, and QVulkanInstance will not own the handle.
+
+    \note It is up to the component creating the external instance to ensure
+    the necessary extensions are enabled on it. These are: \c{VK_KHR_surface},
+    the WSI-specific \c{VK_KHR_*_surface} that is appropriate for the platform
+    in question, and \c{VK_EXT_debug_report} in case QVulkanInstance's debug
+    output redirection is desired.
+
+    \section1 Accessing Core Vulkan Commands
+
+    To access the \c VkInstance handle the QVulkanInstance wraps, call
+    vkInstance(). To resolve Vulkan functions, call getInstanceProcAddr(). For
+    core Vulkan commands manual resolving is not necessary as they are provided
+    via the QVulkanFunctions and QVulkanDeviceFunctions objects accessible via
+    functions() and deviceFunctions().
+
+    \note QVulkanFunctions and QVulkanDeviceFunctions are generated from the
+    Vulkan API XML specifications when building the Qt libraries. Therefore no
+    documentation is provided for them. They contain the Vulkan 1.0 functions
+    with the same signatures as described in the
+    \l{https://www.khronos.org/registry/vulkan/specs/1.0/html/}{Vulkan API
+    documentation}.
+
+    \section1 Getting a Native Vulkan Surface for a Window
+
+    The two common windowing system specific operations are getting a surface
+    (a \c{VkSurfaceKHR} handle) for a window, and querying if a given queue
+    family supports presenting to a given surface. To avoid WSI-specific bits
+    in the applications, these are abstracted by QVulkanInstance and the
+    underlying QPA layers.
+
+    To create a Vulkan surface for a window, or retrieve an existing one,
+    call surfaceForWindow(). Most platforms will only create the surface via
+    \c{VK_KHR_*_surface} when first calling surfaceForWindow(), but there may be
+    platform-specific variations in the internal behavior. Once created,
+    subsequent calls to surfaceForWindow() just return the same handle. This
+    fits the structure of typical Vulkan-enabled QWindow subclasses well.
+
+    To query if a given queue family within a physical device can be used to
+    perform presentation to a given surface, call supportsPresent(). This
+    encapsulates both the generic \c vkGetPhysicalDeviceSurfaceSupportKHR and
+    the WSI-specific \c{vkGetPhysicalDevice*PresentationSupportKHR} checks.
+
+    \section1 Troubleshooting
+
+    Besides returning \c false from create() or \c 0 from surfaceForWindow(),
+    critical errors will also get printed to the debug output via qWarning().
+    Additional logging can be requested by enabling debug output for the
+    logging category \c{qt.vulkan}. The actual Vulkan error code from instance
+    creation can be retrieved by calling errorCode() after a failing create().
+
+    In some special cases it may be necessary to override the Vulkan
+    library name. This can be achieved by setting the \c{QT_VULKAN_LIB}
+    environment variable.
+
+    \section1 Example
+
+    The following is the basic outline of creating a Vulkan-capable QWindow:
+
+    \code
+    class VulkanWindow : public QWindow
+    {
+    public:
+        VulkanWindow() {
+            setSurfaceType(VulkanSurface);
+        }
+
+        void exposeEvent(QExposeEvent *) {
+            if (isExposed()) {
+                if (!m_initialized) {
+                    m_initialized = true;
+                    // initialize device, swapchain, etc.
+                    QVulkanInstance *inst = vulkanInstance();
+                    QVulkanFunctions *f = inst->functions();
+                    uint32_t devCount = 0;
+                    f->vkEnumeratePhysicalDevices(inst->vkInstance(), &devCount, nullptr);
+                    ...
+                    // build the first frame
+                    render();
+                }
+            }
+        }
+
+        bool event(QEvent *e) {
+            if (e->type == QEvent::UpdateRequest)
+                render();
+            return QWindow::event(e);
+        }
+
+        void render() {
+           ...
+           requestUpdate(); // render continuously
+        }
+
+    private:
+        bool m_initialized = false;
+    };
+
+    int main(int argc, char **argv)
+    {
+        QGuiApplication app(argc, argv);
+
+        QVulkanInstance inst;
+        if (!inst.create()) {
+            qWarning("Vulkan not available");
+            return 1;
+        }
+
+        VulkanWindow window;
+        window.showMaximized();
+
+        return app.exec();
+
+    }
+    \endcode
+
+    \note In addition to expose, a well-behaving window implementation will
+    also have to take care of additional events like resize and
+    QPlatformSurfaceEvent in order to ensure proper management of the
+    swap chain. Additionally, some platforms may require releasing resources
+    when not being exposed anymore.
+
+    \section1 Using C++ Bindings for Vulkan
+
+    Combining Qt's Vulkan enablers with a C++ Vulkan wrapper, for example
+    \l{https://github.com/KhronosGroup/Vulkan-Hpp}{Vulkan-Hpp}, is possible as
+    well. The pre-requisite here is that the C++ layer must be able to adopt
+    native handles (VkInstance, VkSurfaceKHR) in its classes without taking
+    ownership (since the ownership stays with QVulkanInstance and QWindow).
+    Consider also the following:
+
+    \list
+
+    \li Some wrappers require exception support to be enabled. Qt does not use
+    exceptions. To enable exceptions for the application, add \c{CONFIG += exceptions}
+    to the \c{.pro} file.
+
+    \li Some wrappers call Vulkan functions directly, assuming \c{vulkan.h}
+    provides prototypes and the application links to a Vulkan library exporting
+    all necessary symbols. Qt may not directly link to a Vulkan library.
+    Therefore, on some platforms it may be necessary to add
+    \c{LIBS += -lvulkan} or similar in the application's \c{.pro} file.
+
+    \li The headers for the QVulkan classes may include \c{vulkan.h} with
+    \c{VK_NO_PROTOTYPES} enabled. This can cause issues in C++ wrapper headers
+    that rely on the prototypes. Hence in application code it may be
+    necessary to include \c{vulkan.hpp} or similar before any of the QVulkan
+    headers.
+

+  \class QVulkanWindow
+  \inmodule QtGui
+  \since 5.10
+  \brief The QVulkanWindow class is a convenience subclass of QWindow to perform Vulkan rendering.
+
+  QVulkanWindow is a Vulkan-capable QWindow that manages a Vulkan device, a
+  graphics queue, a command pool and buffer, a depth-stencil image and a
+  double-buffered FIFO swapchain, while taking care of correct behavior when it
+  comes to events like resize, special situations like not having a device
+  queue supporting both graphics and presentation, device lost scenarios, and
+  additional functionality like reading the rendered content back. Conceptually
+  it is the counterpart of QOpenGLWindow in the Vulkan world.
+
+  \note QVulkanWindow does not always eliminate the need to implement a fully
+  custom QWindow subclass as it will not necessarily be sufficient in advanced
+  use cases.
+
+  QVulkanWindow can be embedded into QWidget-based user interfaces via
+  QWidget::createWindowContainer(). This approach has a number of limitations,
+  however. Make sure to study the
+  \l{QWidget::createWindowContainer()}{documentation} first.
+
+  A typical application using QVulkanWindow may look like the following:
+
+  \code
+  class VulkanRenderer : public QVulkanWindowRenderer
+  {
+  public:
+      VulkanRenderer(QVulkanWindow *w) : m_window(w) { }
+
+      void initResources() override
+      {
+          m_devFuncs = m_window->vulkanInstance()->deviceFunctions(m_window->device());
+          ...
+      }
+      void initSwapChainResources() override { ... }
+      void releaseSwapChainResources() override { ... }
+      void releaseResources() override { ... }
+
+      void startNextFrame() override
+      {
+          VkCommandBuffer cmdBuf = m_window->currentCommandBuffer();
+          ...
+          m_devFuncs->vkCmdBeginRenderPass(...);
+          ...
+          m_window->frameReady();
+      }
+
+  private:
+      QVulkanWindow *m_window;
+      QVulkanDeviceFunctions *m_devFuncs;
+  };
+
+  class VulkanWindow : public QVulkanWindow
+  {
+  public:
+      QVulkanWindowRenderer *createRenderer() override {
+          return new VulkanRenderer(this);
+      }
+  };
+
+  int main(int argc, char *argv[])
+  {
+      QGuiApplication app(argc, argv);
+
+      QVulkanInstance inst;
+      // enable the standard validation layers, when available
+      inst.setLayers(QByteArrayList() << "VK_LAYER_LUNARG_standard_validation");
+      if (!inst.create())
+          qFatal("Failed to create Vulkan instance: %d", inst.errorCode());
+
+      VulkanWindow w;
+      w.setVulkanInstance(&inst);
+      w.showMaximized();
+
+      return app.exec();
+  }
+  \endcode
+
+  As it can be seen in the example, the main patterns in QVulkanWindow usage are:
+
+  \list
+
+  \li The QVulkanInstance is associated via QWindow::setVulkanInstance(). It is
+  then retrievable via QWindow::vulkanInstance() from everywhere, on any
+  thread.
+
+  \li Similarly to QVulkanInstance, device extensions can be queried via
+  supportedDeviceExtensions() before the actual initialization. Requesting an
+  extension to be enabled is done via setDeviceExtensions(). Such calls must be
+  made before the window becomes visible, that is, before calling show() or
+  similar functions. Unsupported extension requests are gracefully ignored.
+
+  \li The renderer is implemented in a QVulkanWindowRenderer subclass, an
+  instance of which is created in the createRenderer() factory function.
+
+  \li The core Vulkan commands are exposed via the QVulkanFunctions object,
+  retrievable by calling QVulkanInstance::functions(). Device level functions
+  are available after creating a VkDevice by calling
+  QVulkanInstance::deviceFunctions().
+
+  \li The building of the draw calls for the next frame happens in
+  QVulkanWindowRenderer::startNextFrame(). The implementation is expected to
+  add commands to the command buffer returned from currentCommandBuffer().
+  Returning from the function does not indicate that the commands are ready for
+  submission. Rather, an explicit call to frameReady() is required. This allows
+  asynchronous generation of commands, possibly on multiple threads. Simple
+  implementations will simply call frameReady() at the end of their
+  QVulkanWindowRenderer::startNextFrame().
+
+  \li The basic Vulkan resources (physical device, graphics queue, a command
+  pool, the window's main command buffer, image formats, etc.) are exposed on
+  the QVulkanWindow via lightweight getter functions. Some of these are for
+  convenience only, and applications are always free to query, create and
+  manage additional resources directly via the Vulkan API.
+
+  \li The renderer lives in the gui/main thread, like the window itself. This
+  thread is then throttled to the presentation rate, similarly to how OpenGL
+  with a swap interval of 1 would behave. However, the renderer implementation
+  is free to utilize multiple threads in any way it sees fit. The accessors
+  like vulkanInstance(), currentCommandBuffer(), etc. can be called from any
+  thread. The submission of the main command buffer, the queueing of present,
+  and the building of the next frame do not start until frameReady() is
+  invoked on the gui/main thread.
+
+  \li When the window is made visible, the content is updated automatically.
+  Further updates can be requested by calling QWindow::requestUpdate(). To
+  render continuously, call requestUpdate() after frameReady().
+
+  \endlist
+
+  For troubleshooting, enable the logging category \c{qt.vulkan}. Critical
+  errors are printed via qWarning() automatically.
+
+  \section1 Coordinate system differences between OpenGL and Vulkan
+
+  There are two notable differences to be aware of: First, with Vulkan Y points
+  down the screen in clip space, while OpenGL uses an upwards pointing Y axis.
+  Second, the standard OpenGL projection matrix assume a near and far plane
+  values of -1 and 1, while Vulkan prefers 0 and 1.
+
+  In order to help applications migrate from OpenGL-based code without having
+  to flip Y coordinates in the vertex data, and to allow using QMatrix4x4
+  functions like QMatrix4x4::perspective() while keeping the Vulkan viewport's
+  minDepth and maxDepth set to 0 and 1, QVulkanWindow provides a correction
+  matrix retrievable by calling clipCorrectionMatrix().
+
+  \section1 Multisampling
+
+  While disabled by default, multisample antialiasing is fully supported by
+  QVulkanWindow. Additional color buffers and resolving into the swapchain's
+  non-multisample buffers are all managed automatically.
+
+  To query the supported sample counts, call supportedSampleCounts(). When the
+  returned set contains 4, 8, ..., passing one of those values to setSampleCount()
+  requests multisample rendering.
+
+  \note unlike QSurfaceFormat::setSamples(), the list of supported sample
+  counts are exposed to the applications in advance and there is no automatic
+  falling back to lower sample counts in setSampleCount(). If the requested value
+  is not supported, a warning is shown and a no multisampling will be used.
+
+  \section1 Reading images back
+
+  When supportsGrab() returns true, QVulkanWindow can perform readbacks from
+  the color buffer into a QImage. grab() is a slow and inefficient operation,
+  so frequent usage should be avoided. It is nonetheless valuable since it
+  allows applications to take screenshots, or tools and tests to process and
+  verify the output of the GPU rendering.
+
+  \section1 sRGB support
+
+  While many applications will be fine with the default behavior of
+  QVulkanWindow when it comes to swapchain image formats,
+  setPreferredColorFormats() allows requesting a pre-defined format. This is
+  useful most notably when working in the sRGB color space. Passing a format
+  like \c{VK_FORMAT_B8G8R8A8_SRGB} results in choosing an sRGB format, when
+  available.
+
+  \section1 Validation layers
+
+  During application development it can be extremely valuable to have the
+  Vulkan validation layers enabled. As shown in the example code above, calling
+  QVulkanInstance::setLayers() on the QVulkanInstance before
+  QVulkanInstance::create() enables validation, assuming the Vulkan driver
+  stack in the system contains the necessary layers.
+
+  \note Be aware of platform-specific differences. On desktop platforms
+  installing the \l{https://www.lunarg.com/vulkan-sdk/}{Vulkan SDK} is
+  typically sufficient. However, Android for example requires deploying
+  additional shared libraries together with the application, and also mandates
+  a different list of validation layer names. See
+  \l{https://developer.android.com/ndk/guides/graphics/validation-layer.html}{the
+  Android Vulkan development pages} for more information.
+
+  \note QVulkanWindow does not expose device layers since this functionality
+  has been deprecated since version 1.0.13 of the Vulkan API.

-    locking_function(int mode, int n, const char *file, int line) is needed to

-    whenever multiple threads use OpenSSL.)  Multi-threaded
-    applications will crash at random if it is not set.  ...
-    ...
-    id_function(void) is a function that returns a thread ID. It is not

+    locking_function(int mode, int n, const char *file, int line) is needed to

+    whenever multiple threads use OpenSSL.)  Multi-threaded
+    applications will crash at random if it is not set.  ...
+    ...

+    to sending core events for every XI_* event that is sent directly by a slave device. For more
+    details see "Event processing for attached slave devices" in XInput2 specification. To prevent
+    handling of the same event twice, we have checks for xi2MouseEventsDisabled() in XI2 event
+    handlers (but this is somewhat inconsistent in some situations). If the purpose for
+    QT_XCB_NO_XI2_MOUSE was so that an application using QAbstractNativeEventFilter would see core
+    mouse events before they are handled by Qt then QT_XCB_NO_XI2_MOUSE won't always work as
+    expected (e.g. we handle scroll event directly from a slave device event, before an application
+    has seen the fallback core event from a master device).
+
+    The commit introducing QT_XCB_NO_XI2_MOUSE also states that setting this envvar "restores the
+    old behavior with broken grabbing". It did not elaborate why grabbing was not fixed for this
+    code path. The issue that this envvar tries to solve seem to be less important than broken
+    grabbing (broken apparently only for touch events). Thus, if you really want core mouse events
+    in your application and do not care about broken touch, then use QT_XCB_NO_XI2 (more on this
+    below) to disable the extension all together. The reason why grabbing might have not been fixed
+    is that calling XIGrabDevice with this code path for some reason always returns AlreadyGrabbed
+    (by debugging X server's code it appears that when we call XIGrabDevice, an X server first grabs
+    pointer via core pointer and then fails to do XI2 grab with AlreadyGrabbed; disclaimer - I did
+    not debug this in great detail). When we try supporting odd setups like QT_XCB_NO_XI2_MOUSE, we
+    are asking for trouble anyways.
+
+    In conclusion, introduction of QT_XCB_NO_XI2_MOUSE causes more issues than solves - the above
+    mentioned inconsistencies, maintenance of this code path and that QT_XCB_NO_XI2_MOUSE replaces
+    less important issue with somewhat more important issue. It also makes us to use less optimal
+    code paths in certain situations (see xi2HandleHierarchyEvent). Using of QT_XCB_NO_XI2 has its
+    drawbacks too - no tablet and touch events. So the only real fix in this case is at an
+    application side (teach the application about xcb_ge_event_t events). Based on this,
+    QT_XCB_NO_XI2_MOUSE will be removed in ### Qt 6. It should not have existed in the first place,
+    native events seen by QAbstractNativeEventFilter is not really a public API, applications should
+    expect changes at this level and do ifdefs if something changes between Qt version.

+    Using _NET_WORKAREA to calculate the available desktop geometry on multi-head systems (systems
+    with more than one monitor) is unreliable. Different WMs have different interpretations of what
+    _NET_WORKAREA means with multiple attached monitors. This gets worse when monitors have
+    different dimensions and/or screens are not virtually aligned. In Qt we want the available
+    geometry per monitor (QScreen), not desktop (represented by _NET_WORKAREA). WM specification
+    does not have an atom for this. Thus, QScreen is limted by the lack of support from the
+    underlying system.
+
+    One option could be that Qt does WM's job of calculating this by subtracting geometries of
+    _NET_WM_STRUT_PARTIAL and windows where _NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_DOCK.
+    But this won't work on Gnome 3 shell as it seems that on this desktop environment the tool panel
+    is painted directly on the root window. Maybe there is some Gnome/GTK API that could be used
+    to get height of the panel, but I did not find one. Maybe other WMs have their own tricks, so
+    the reliability of this approach is questionable.

+    \section3 Enable REGEXP operator
+
+    SQLite comes with a REGEXP operation. However the needed implementation must
+    be provided by the user. For convenience a default implementation can be
+    enabled by \l{QSqlDatabase::setConnectOptions()} {setting the connect
+    option} \c{QSQLITE_ENABLE_REGEXP} before \l{QSqlDatabase::open()} {the
+    database connection is opened}. Then a SQL statement like "column REGEXP
+    'pattern'" basically expands to the Qt code
+
+    \snippet code/doc_src_sql-driver.cpp 34
+
+    For better performance the regular expressions are cached internally. By
+    default the cache size is 25, but it can be changed through the option's
+    value. For example passing "\c{QSQLITE_ENABLE_REGEXP=10}" reduces the
+    cache size to 10.
+
     \section3 QSQLITE File Format Compatibility
 
     SQLite minor releases sometimes break file format forward compatibility.

    QCOMPARE tries to output the contents of the values if the comparison fails,

-   QCOMPARE is very strict on the data types. Both \a actual and \a expected
-   have to be of the same type, otherwise the test won't compile. This prohibits

     This is mainly useful for asynchronous systems like X11, where a window will be mapped to screen some
     time after being asked to show itself on the screen.

+    area is completely covered by other windows, or if the window is otherwise not visible. This function

+    \since 5.10
+
+    In some applications, it may make sense to have actions with shortcuts in
+    context menus. If true, the shortcut (if valid) is shown when the action is
+    shown via a context menu, when it is false, it is not shown.
+
+    The default is to follow whether the Qt::AA_DontShowShortcutsInContextMenus attribute
+    is set for the application, falling back to the widget style hint.
+    Explicitly setting this property overrides the presence (or abscence) of the attribute.
