Notably, the QWidget class (which we can also embed in - a QGraphicsView) has properties for its bounds, colors, etc. - Let's look at a small example: + The framework lets you animate the Qt properties of the existing + classes in Qt.

It is also possible to set values - situated between the start and end value. The interpolation - will then go by these points. + It uses the linear interpolation method to control the speed of + animation between the start and end values. Try adding another value + in--between the start and end value to see how they are interpolated. + This time use the QPropertyAnimation::setKeyValueAt function to add + these values: \code - QPushButton button("Animated Button"); - button.show(); - - QPropertyAnimation animation(&button, "geometry"); - animation.setDuration(10000); - - animation.setKeyValueAt(0, QRect(0, 0, 100, 30)); - animation.setKeyValueAt(0.8, QRect(250, 250, 100, 30)); - animation.setKeyValueAt(1, QRect(0, 0, 100, 30)); - - animation.start(); + ... + anim->setDuration(10000); + anim->setKeyValueAt(0, QPoint(0, 0)); + anim->setKeyValueAt(0.8, QPoint(250, 250)); + anim->setKeyValueAt(1, QPoint(0, 0)); + ... \endcode - In this example, the animation will take the button to (250, 250) - in 8 seconds, and then move it back to its original position in - the remaining 2 seconds.

The button's movement is linear-interpolated + between these points. - You also have the possibility to animate values of a QObject - that is not declared as a Qt property. The only requirement is - that this value has a setter. You can then subclass the class - containing the value and declare a property that uses this setter. - Note that each Qt property requires a getter, so you will need to - provide a getter yourself if this is not defined. + You can also animate a QObject's value that is not declared as a Qt + property, if the value has a setter method. In such cases, derive + a new class from the class that contains the value, and add a Qt property + for that value with the setter. + + \note Each Qt property requires a getter also, so you should provide a + getter if that is not defined. \code class MyGraphicsRectItem : public QObject, public QGraphicsRectItem { Q_OBJECT - Q_PROPERTY(QRectF geometry READ geometry WRITE setGeometry) + Q_PROPERTY(QPointF pos READ pos WRITE setPos) }; \endcode - In the above code example, we subclass QGraphicsRectItem and - define a geometry property. We can now animate the widgets - geometry even if QGraphicsRectItem does not provide the geometry - property. + In this example, the \c MyGraphicsRectItem derives from + QGraphicsRectItem and QObject, and defines the \c pos property.

When the application is a macOS app bundle +or a Windows executable, \c{qt_deploy_runtime_dependencies()} can be called +from an install-time script to deploy those dependencies. It will install +non-system Qt libraries plus an appropriate set of Qt plugins. + +On Linux, the command will deploy additional libraries, beyond just those +related to Qt, that are included with the project. However, when executed on +macOS or Windows, the command will use either \c macdeployqt or \c windeployqt, +which will only deploy libraries that are specific to Qt. + +This command only considers runtime dependencies for which linking +relationships exist in the underlying binaries. It does not deploy QML modules, +see \l{qt6_deploy_qml_imports}{qt_deploy_qml_imports()} for that. + +\section1 Arguments + +The \c{EXECUTABLE} option must be provided. + +The \c{executable} argument should be the path to the executable file in the +build directory. For example, \c{${CMAKE_CURRENT_BINARY_DIR}/MyApp.exe}, or more +dynamically \c{$<TARGET_FILE:MyApp>}. Specifying raw target names not wrapped in +a generator expression like \c{<TARGET_FILE:>} is not supported. + +For macOS app bundles, the \c{executable} argument should be a path to the +bundle directory, relative to the base install location. +For example \c{MyApp.app}, or more dynamically +\c{$<TARGET_FILE_NAME:MyApp>.app}. +Specifying raw target names not wrapped in a generator epxression like +\c{<TARGET_FILE_NAME:>} is not supported. + +It may also be desirable to install dependencies for other binaries related to +the \c{executable}. For example, plugins provided by the project might have +further dependencies, but because those plugins won't be linked directly to the +executable, \c{qt_deploy_runtime_dependencies()} won't automatically discover +them. The \c{ADDITIONAL_EXECUTABLES}, \c{ADDITIONAL_LIBRARIES}, and +\c{ADDITIONAL_MODULES} options can be used to specify additional binaries +whose dependencies should also be deployed (installing the named binaries +themselves is still the project's responsibility). The naming of these keywords +follows CMake's conventions, so Qt plugins would be specified using +\c{ADDITIONAL_MODULES}. +Each value should be a path relative to the base install location. The values +can use generator expressions, same as with the \c{EXECUTABLE} option. +Specifying raw target names not wrapped in a generator epxression like +\c{<TARGET_FILE_NAME:>} is not supported. + +When installing a Windows application, it is common to need a +\l{Using qt.conf}{qt.conf} file when following CMake's default install +directory structure. If the \c{GENERATE_QT_CONF} option is given, an appropriate +\c{qt.conf} file will be written to the same directory as the \c{executable}. +The paths in that \c{qt.conf} file will be based on the \c{CMAKE_INSTALL_xxxDIR} +variables, whose defaults are provided by CMake's \l{GNUInstallDirs} module. + +You can override some of those defaults with the parameters in the following +table, all of which are expected to be relative to the base install location. + +\table +\header + \li parameter + \li affected variable + \li notes +\row + \li \c BIN_DIR + \li \l QT_DEPLOY_BIN_DIR + \li +\row + \li \c LIBEXEC_DIR + \li \l QT_DEPLOY_LIBEXEC_DIR + \li since Qt 6.7 +\row + \li \c LIB_DIR + \li \l QT_DEPLOY_LIB_DIR + \li +\row + \li \c PLUGINS_DIR + \li \l QT_DEPLOY_PLUGINS_DIR + \li +\row + \li \c QML_DIR + \li \l QT_DEPLOY_QML_DIR + \li +\endtable + +A \c{qt.conf} file is always written if \c{executable} is a macOS app bundle, +regardless of whether or not \c{GENERATE_QT_CONF} is provided. The \c{..._DIR} +options are also ignored in that case, since the directory layout of an app +bundle is dictated by Apple's requirements. + +More verbose output about the deployment steps can be enabled by providing the +\c{VERBOSE} option. Alternatively, the \l{QT_ENABLE_VERBOSE_DEPLOYMENT} +variable can be set in the project before the first \c{find_package(Qt6)} call +to make deployment output verbose by default. + +The \c{qt_deploy_runtime_dependencies()} command overwrites existing files by +default (some warnings may still be issued). Use the \c{NO_OVERWRITE} option +to prevent overwriting existing files. Note that this option currently only +affects macOS and Windows deployments. + +By default, if \c{executable} is a macOS app bundle, only Qt plugins and Qt +libraries that comply with Apple's app store requirements are deployed. The +\c{NO_APP_STORE_COMPLIANCE} option can be given to disable that constraint. + +On platforms other than macOS, Qt translations are automatically deployed.

Use +\l{qt6_deploy_translations}{qt_deploy_translations()} to deploy translations +in a customized way. + +For Windows desktop applications, the required runtime files for the compiler +are also installed by default. To prevent this, specify \c{NO_COMPILER_RUNTIME}. + +Since Qt 6.7, you can use \c{DEPLOY_TOOL_OPTIONS} to pass additional options to +the underlying deployment tool.

This defines + appropriate defaults for variables like \c{CMAKE_INSTALL_BINDIR}, + \c{CMAKE_INSTALL_LIBDIR}, and so on. +\li When targeting Windows, if the \c{CMAKE_RUNTIME_OUTPUT_DIRECTORY} variable + is not already set, it will be set to + \c{${CMAKE_CURRENT_BINARY_DIR}}. +\li When target platforms other than Apple or Windows, \c{CMAKE_INSTALL_RPATH} + will be augmented as described below. +\li CMake's \l USE_FOLDERS property is set to \c{ON}, and \l QT_TARGETS_FOLDER is + set to \c{QtInternalTargets}. IDEs that support folders will display + Qt-internal targets in this folder. +\endlist + +Since Qt 6.5, it is possible to change the default behavior of Qt's CMake +API by opting in to changes from newer Qt versions. If \c{REQUIRES} is +specified, all suggested changes introduced in Qt up to \c{REQUIRES} are enabled, +and using an older Qt version will result in an error. +If additionally \c{SUPPORTS_UP_TO} has been specified, any new changes introduced +in versions up to \c{SUPPORTS_UP_TO} are also enabled (but using an older Qt +version is not an error). This is similar to CMake's policy concept +(compare \l{cmake_policy}). + +On platforms that support \c{RPATH} (other than Apple platforms), two values +are appended to the \c{CMAKE_INSTALL_RPATH} variable by this command. +\c{$ORIGIN} is appended so that libraries will find other libraries they depend +on in the same directory as themselves. \c{$ORIGIN/<reldir>} is also appended, +where \c{<reldir>} is the relative path from \c{CMAKE_INSTALL_BINDIR} to +\c{CMAKE_INSTALL_LIBDIR}. This allows executables installed to +\c{CMAKE_INSTALL_BINDIR} to find any libraries they may depend on installed to +\c{CMAKE_INSTALL_LIBDIR}. Any duplicates in \c{CMAKE_INSTALL_RPATH} are +removed.

Memory + that is shared with other processes is often referred to as a "segment", + and although it may have been implemented as specific segments on + processors with segmented memory models in the past, this is not the case + in any modern operating system. Shared memory segments are simply regions + of memory that the operating system will ensure are available to all + processes participating. + + \note The address at which the segment is located in memory will almost + always be different for each process that is participating in the sharing. + Therefore, applications must take care to share only position-independent + data, such as primitive C++ types or arrays of such types. + + \section1 Sharing memory using QSharedMemory + + QSharedMemory provides a simple API to create a shared memory segment of a + given size or attach to one that was created by another process. + Additionally, it provides a pair of methods to \l{QSharedMemory::}{lock} + and \l{QSharedMemory::}{unlock} the whole segment, using an internal + \l{QSystemSemaphore}. + + Shared memory segments and system semaphores are globally identified in the + system through a "key", which in Qt is represented by the \l{QNativeIpcKey} + class. Additionally, depending on the OS, Qt may support multiple different + backends for sharing memory; see the \l{Native IPC Keys} documentation for + more information and limitations. + + QSharedMemory is designed to share memory only within the same privilege + level (that is, not with untrusted other processes, such as those started + by other users). For backends that support it, QSharedMemory will create + segments such that only processes with the same privilege level can attach. + + \section1 Sharing memory via memory-mapped files + + Most files can be mapped to memory using QFile::map() and, if the + \l{QFileDevice::MapPrivateOption}{MapPrivateOption} option is not specified, + any writes to the mapped segment will be observed by all other processes + that have mapped the same file. Exceptions to files that can be mapped to + memory include remote files found in network shares or those located in + certain filesystems. Even if the operating system does allow mapping remote + files to memory, I/O operations on the file will likely be cached and + delayed, thus making true memory sharing impossible. + + This solution has the major advantages of being independent of any backend + API and of being simpler to interoperate with from non-Qt applications. + Since \l{QTemporaryFile} is a \l{QFile}, applications can use that class to + achieve clean-up semantics and to create unique shared memory segments too. + + To achieve locking of the shared memory segment, applications will need to + deploy their own mechanisms. One way may be to use \l QLockFile. Another + and less costly solution is to use QBasicAtomicInteger or \c{std::atomic} in + a pre-determined offset in the segment itself. Higher-level locking + primitives may be available on some operating systems; for example, on + Linux, applications can set the "pshared" flag in the mutex attribute + passed to \c{pthread_mutex_create()} to indicate that the mutex resides in + a shared memory segment. + + Be aware that the operating system will likely attempt to commit to + permanent storage any writes made to the shared memory. This may be desired + or it may be a performance penalty if the file itself was meant to be + temporary. In that case, applications should locate a RAM-backed + filesystem, such as \c{tmpfs} on Linux (see + QStorageInfo::fileSystemType()), or pass a flag to the native file-opening + function to inform the OS to avoid committing the contents to storage. + + It is possible to use file-backed shared memory to communicate with + untrusted processes, in which case the application should exercise great + care. The files may be truncated/shrunk and cause applications accessing + memory beyond the file's size to crash. + + \section2 Linux hints on memory-mapped files + + On modern Linux systems, while the \c{/tmp} directory is often a \c{tmpfs} + mount point, that is not a requirement. However, the \c{/dev/shm} directory + is required to be a \c{tmpfs} and exists for the very purpose of sharing + memory. Do note that it is world-readable and writable (like \c{/tmp} and + \c{/var/tmp}), so applications must be careful of the contents revealed + there. Another alternative is to use the XDG Runtime Directory (see + QStandardPaths::writableLocation() and \l{QStandardPaths::RuntimeLocation}), + which on Linux systems using systemd is a user-specific \c{tmpfs}. + + An even more secure solution is to create a "memfd" using \c{memfd_create(2)} + and use interprocess communication to pass the file descriptor, like + \l{QDBusUnixFileDescriptor} or by letting the child process of a \l{QProcess} + inherit it. "memfds" can also be sealed against being shrunk, so they are + safe to be used when communicating with processes with a different privilege + level. + + \section2 FreeBSD hints on memory-mapped files + + FreeBSD also has \c{memfd_create(2)} and can pass file descriptors to other + processes using the same techniques as Linux. It does not have temporary + filesystems mounted by default. + + \section2 Windows hints on memory-mapped files + + On Windows, the application can request the operating system avoid saving + the file's contents on permanent storage. This request is performed by + passing the \c{FILE_ATTRIBUTE_TEMPORARY} flag in the + \c{dwFlagsAndAttributes} parameter to the \c{CreateFile} Win32 function, + the \c{_O_SHORT_LIVED} flag to \c{_open()} low-level function, or by + including the modifier "T" to the + \c{fopen()} C runtime function. + + There's also a flag to inform the operating system to delete the file when + the last handle to it is closed (\c{FILE_FLAG_DELETE_ON_CLOSE}, + \c{_O_TEMPORARY}, and the "D" modifier), but do note that all processes + attempting to open the file must agree on using this flag or not using it. A + mismatch will likely cause a sharing violation and failure to open the file. +*/ + +/*! + \page native-ipc-keys.html + \title Native IPC Keys + \keyword ipc + \keyword shared memory + \keyword system semaphore + + \brief An overview of keys for QSharedMemory and QSystemSemaphore + + The \l QSharedMemory and \l QSystemSemaphore classes identify their + resource using a system-wide identifier known as a "key". The low-level key + value as well as the key type are encapsulated in Qt using the \l + QNativeIpcKey class.

It is always absent with the + Microsoft compiler. + + To determine whether a given key type is supported, applications should + call QSharedMemory::isKeyTypeSupported() and + QSystemSemaphore::isKeyTypeSupported(). + + QNativeIpcKey also provides support for compatibility with Qt applications + prior to its introduction. The following sections detail the limitations of + the backends, the contents of the string keys themselves, and + compatibility. + + \section1 Cross-platform safe key format + + QNativeIpcKey::setNativeKey() and QNativeIpcKey::nativeKey() handle the + low-level native key, which may be used with the native APIs and shared + with other, non-Qt processes (see below for the API). This format is not + usually cross-platform, so both QSharedMemory and QSystemSemaphore provide + a function to translate a cross-platform identifier string to the native + key: QSharedMemory::platformSafeKey() and + QSystemSemaphore::platformSafeKey(). + + The length of the cross-platform key on most platforms is the same as that + of a file name, but is severely limited on Apple platforms to only 30 + usable bytes (be mindful of UTF-8 encoding if using characters outside the + US-ASCII range). The format of the key is also similar to that of a file + path component, meaning it should not contain any characters not allowed in + file names, in particular those that separate path components (slash and + backslash), with the exception of sandboxed applications on Apple operating + systems. The following are good examples of cross-platform keys: "myapp", + "org.example.myapp", "org.example.myapp-12345". Note that it is up to the + caller to prevent oversized keys, and to ensure that the key contains legal + characters on the respective platform. Qt will silently truncate keys that + are too long. + + \b{Apple sandbox limitations:} if the application is running inside of a + sandbox in an Apple operating system, the key must be in a very specific + format: \c {<application group identifier>/<custom identifier>}. Sandboxing + is implied for all applications distributed through the Apple App Store. + See Apple's documentation + \l{https://developer.apple.com/library/archive/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW24} + {here} and \l{https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_application-groups} + {here} for more information, including how to obtain the application's group identifier. + + \section1 Native key format + + This section details the format of the native keys of the supported + backends. + + \section3 POSIX Realtime + Native keys resemble file names and may contain any character that file + names do, except for a slash. POSIX requires the first character in the key + name to be a slash and leaves undetermined whether any additional slashes + are permitted. On most operating systems, the key length is the same as a + file name, but it is limited to 32 characters on Apple operating systems + (this includes the first slash and the terminating null, so only 30 usable + characters are possible). + + The following are good examples of native POSIX keys: "/myapp", + "/org.example.myapp", "/org.example.myapp-12345". + + QSharedMemory::platformSafeKey() and QSystemSemaphore::platformSafeKey() + simply prepend the slash. On Apple operating systems, they also truncate + the result to the available size. + + \section3 Windows + Windows key types are NT + \l{https://learn.microsoft.com/en-us/windows/win32/sync/object-namespaces}{kernel + object names} and may be up to \c{MAX_PATH} (260) characters in length. + They look like relative paths (that is, they don't start with a backslash + or a drive letter), but unlike file names on Windows, they are + case-sensitive. + + The following are good examples of native Windows keys: "myapp", + "org.example.myapp", "org.example.myapp-12345". + + QSharedMemory::platformSafeKey() and QSystemSemaphore::platformSafeKey() + insert a prefix to disambiguate shared memory and system semaphores, + respectively. + + \section3 X/Open System Interfaces (XSI) / System V + System V keys take the form of the name of a file in the system, and thus + have the exact same limitations as file paths do. Both QSharedMemory and + QSystemSemaphore will create this file if it does not exist when creating + the object. If auto-removal is disabled, it may also be shared between + QSharedMemory and QSystemSemaphore without conflict and can be any extant + file (for example, it can be the process executable itself, see + QCoreApplication::applicationFilePath()). The path should be an absolute + one to avoid mistakes due to different current directories. + + QSharedMemory::platformSafeKey() and QSystemSemaphore::platformSafeKey() + always return an absolute path. If the input was already absolute, they + will return their input unchanged. Otherwise, they will prepend a suitable + path where the application usually has permission to create files in. + + \section1 Ownership + + Shared memory and system semaphore objects need to be created before use, + which is accomplished with QSharedMemory::create() or by passing + QSystemSemaphore::Create to the constructor, respectively. + + On Unix systems, the Qt classes that created the object will be responsible + for cleaning up the object in question. Therefore, if the application with + that C++ object exits uncleanly (a crash, qFatal(), etc.), the object may + be left behind. If that happens, applications may fail to create the + object again and should instead attach to an existing one. For example, for + QSharedMemory: + + \code + if (!shm.create(4096) && shm.error() == QSharedMemory::AlreadyExists) + shm.attach(); + \endcode + + Re-attaching to a QSystemSemaphore is probably unwise, as the token counter + in it is probably in an unknown state and therefore may lead to deadlocks. + + \section3 POSIX Realtime + POSIX Realtime object ownership is patterned after files, in the sense that + they exist independent of any process using them or not. Qt is unable to + determine if the object is still in use, so auto-removal will remove it + even then, which will make attaching to the same object impossible but + otherwise not affecting existing attachments. + + Prior to Qt 6.6, Qt never cleaned up POSIX Realtime objects, except on QNX. + + \section3 X/Open System Interfaces (XSI) / System V + There are two resources managed by the Qt classes: the file the key refers + to and the object itself. QSharedMemory manages the object cooperatively: + the last attachment is responsible for removing the object itself and then + removing the key file. QSystemSemaphore will remove the object if and only + if it was passed QSystemSemaphore::Create; additionally, if it created the + key file, it will remove that too. + + Since Qt 6.6, it is possible to ask either class not to clean up. + + \section3 Windows + The operating system owns the object and will clean up after the last + handle to the object is closed. + + \section1 Interoperability with old Qt applications + + The QNativeIpcKey class was introduced in Qt 6.6. Prior to this version, + QSharedMemory and QSystemSemaphore backends were determined at the time of + Qt's own build. For Windows systems, it was always the Windows backend. For + Unix systems, it defaulted to the System V backend if the configuration + script determined it was available. If it was not available, it fell back + to the POSIX one. The POSIX backend could be explicitly + selected using the \c{-feature-ipc_posix} option to the Qt configure + script; if it was enabled, the \c{QT_POSIX_IPC} macro would be defined. + + Qt 6.6 retains the configure script option but it no longer controls the + availability of the backends. Instead, it changes what + QNativeIpcKey::legacyDefaultTypeForOs() will return. Applications that need + to retain compatibility must use this key type exclusively to guarantee + interoperability. + + The API in both QSharedMemory and QSystemSemaphore had the concept of a + cross-platform key, which is now deprecated in favor of using + QSharedMemory::legacyNativeKey() and QSystemSemaphore::legacyNativeKey(). + Those two functions produce the same native key as the deprecated functions + did in prior versions. If the old code was for example: + + \code + QSharedMemory shm("org.example.myapplication"); + QSystemSemaphore sem("org.example.myapplication"); + \endcode + + It can be updated to be: + \code + QSharedMemory shm(QSharedMemory::legacyNativeKey("org.example.myapplication")); + QSystemSemaphore sem(QSystemSemaphore::legacyNativeKey("org.example.myapplication")); + \endcode + + If the two applications exchanged native keys, there is no need to update + code such as: + + \code + QSharedMemory shm; + shm.setNativeKey(key); + \endcode + + Though if the older application did accept a native key, the new one may + opt to use \c{platformSafeKey()} with a second argument of + QNativeIpcKey::legacyDefaultTypeForOs(). + + \section3 X/Open System Interfaces (XSI) / System V + Never use existing files for QSharedMemory keys, as the old Qt application + may attempt to remove it. Instead, let QSharedMemory create it. + + \section1 Interoperability with non-Qt applications + + Interoperability with non-Qt applications is possible, with some limitations: + \list + \li Creation of shared memory segments must not race + \li QSharedMemory support for locking the segment is unavailable + \endlist + + Communication with non-Qt applications must always be through the native + key. + + QSharedMemory always maps the entire segment to memory. The non-Qt + application may choose to only map a subset of it to memory, with no ill + effects. + + \section3 POSIX Realtime + POSIX shared memory can be opened using + \l{https://pubs.opengroup.org/onlinepubs/9699919799/functions/shm_open.html}{shm_open()} + and POSIX system semaphores can be opened using + \l{https://pubs.opengroup.org/onlinepubs/9699919799/functions/sem_open.html}{sem_open()}. + + Both of those functions take a \c name parameter that is the result of + QNativeIpcKey::nativeKey(), encoded for file names using + QFile::encodeName() / QFile::decodeName(). + + \section3 Windows + Windows shared memory objects can be opened using + \l{https://learn.microsoft.com/en-us/windows/win32/api/memoryapi/nf-memoryapi-createfilemappingw}{CreateFileMappingW} + and Windows system semaphore objects can be opened using + \l{https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-createsemaphorew}{CreateSemaphoreW}. + Despite the name of both functions starting with "Create", they are able + to attach to existing objects. + + The \c lpName parameter to those functions is the result of + QNativeIpcKey::nativeKey(), without transformation. + + If the foreign application uses the non-Unicode version of those functions + (ending in "A"), the name can be converted to and from 8-bit using QString. + + \section3 X/Open System Interfaces (XSI) / System V + System V shared memory can be obtained using + \l{https://pubs.opengroup.org/onlinepubs/9699919799/functions/shmget.html}{shmget()} + and System V system semaphores can be obtained using + \l{https://pubs.opengroup.org/onlinepubs/9699919799/functions/semget.html}{semget()}. + + The \c{key} parameter to either of those functions is the result of the + \l{https://pubs.opengroup.org/onlinepubs/9699919799/functions/ftok.html}{ftok()} + function when passed the file name obtained from QNativeIpcKey::nativeKey() + with an \c id of 81 or 0x51 (the ASCII capital letter 'Q'). + + System V semaphore objects may contain multiple semaphores, but + QSystemSemaphore only uses the first one (number 0 for \c{sem_num}). + + Both QSharedMemory and QSystemSemaphore default to removing the object + using the \c{IPC_RMID} operation to \c{shmctl()} and \c{semctl()} + respectively if they are the last attachment. +*/ diff --git a/src/corelib/doc/src/java-style-iterators.qdoc b/src/corelib/doc/src/java-style-iterators.qdoc index 69b9592996..d486b73488 100644 --- a/src/corelib/doc/src/java-style-iterators.qdoc +++ b/src/corelib/doc/src/java-style-iterators.qdoc @@ -1,29 +1,5 @@ -/**************************************************************************** -** -** Copyright (C) 2020 The Qt Company Ltd. -** Contact: https://www.qt.io/licensing/ -** -** This file is part of the documentation of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:FDL$ -** Commercial License Usage -** Licensees holding valid commercial Qt licenses may use this file in -** accordance with the commercial license agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and The Qt Company.

For example: - - \code - QString source("abc123"); - - QRegExp("\\d+").exactMatch(source); // returns false - QRegExp("[a-z]+\\d+").exactMatch(source); // returns true - - QRegularExpression("\\d+").match(source).hasMatch(); // returns true - QRegularExpression("[a-z]+\\d+").match(source).hasMatch(); // returns true - \endcode - - Exact matching is not reflected in \l QRegularExpression.

QRegularExpression instead does support - greedy, lazy and possessive quantifiers. The \l - {QRegularExpression::InvertedGreedinessOption} pattern option can be useful - to emulate the effects of \c QRegExp::setMinimal(): if enabled, it inverts - the greediness of quantifiers (greedy ones become lazy and vice versa). - - \section3 Different pattern syntax - - Porting a regular expression from \c QRegExp to \l QRegularExpression may - require changes to the pattern itself. Therefore it is recommended to check - the pattern used with the \l {QRegularExpression::isValid} method. This is - especially important for user provided pattern or pattern not controlled by - the developer. - - In other cases, a pattern ported from \c QRegExp to \l QRegularExpression may - silently change semantics. Therefore, it is necessary to review the patterns - used. The most notable cases of silent incompatibility are: - - \list - \li Curly braces are needed in order to use a hexadecimal escape like \c - {\xHHHH} with more than 2 digits. A pattern like \c {\x2022} needs - to be ported to \c {\x{2022}}, or it will match a space \c {(0x20)} - followed by the string \c {"22"}. In general, it is highly recommended - to always use curly braces with the \c {\x} escape, no matter the - amount of digits specified. - - \li A \c{0-to-n} quantification like \c {{,n}} needs to be ported to - \c {{0,n}} to preserve semantics. Otherwise, a pattern such as - \c {\d{,3}} would actually match a digit followed by the exact - string \c {"{,3}"}. - \endlist - - \section3 Partial Matching + In Qt 6, the \c QRegExp type has been retired to the Qt5Compat module + and all Qt APIs using it have been removed from other modules. + Client code which used it can be ported to use \l QRegularExpression + in its place. As \l QRegularExpression is present already in Qt 5, + this can be done and tested before migration to Qt 6. - When using \c QRegExp::exactMatch(), if an exact match was not found, one - could still find out how much of the subject string was matched by the - regular expression by calling \c QRegExp::matchedLength(). If the returned - length was equal to the subject string's length, then one could conclude - that a partial match was found. - \l QRegularExpression supports partial matching explicitly by means of the - appropriate \l {QRegularExpression::MatchType}. - - \section3 Global matching - - Due to limitations of the \c QRegExp API it was impossible to implement - global matching correctly (that is, like Perl does). In particular, patterns - that can match zero characters (like "a*") are problematic. \l - {QRegularExpression::wildcardToRegularExpression} implements Perl global - match correctly, and the returned iterator can be used to examine each - result. - - \section3 Unicode properties support - - When using \c QRegExp, character classes such as \c{\w}, \c{\d}, etc. match - characters with the corresponding Unicode property: for instance, \c{\d} - matches any character with the Unicode Nd (decimal digit) property. Those - character classes only match ASCII characters by default. When using \l - QRegularExpression: for instance, \c{\d} matches exactly a character in the - 0-9 ASCII range. It is possible to change this behavior by using the \l - {QRegularExpression::UseUnicodePropertiesOption} - pattern option. + \include corelib/port-from-qregexp.qdocinc porting-to-qregularexpression \section2 The QRegExp class In Qt6 \l QRegExp got removed from Qt Core.
