Originally it only checked the certificate dates, but later checking for blacklisting was added. Now there's a more specific QSslCertificate::isBlacklisted() method. - Unite clipping support has been removed from QPainter. The alternative is to unite QRegion's and using the result on QPainter. - QLibrary::resolve() now returns a function pointer instead of a void pointer. - QSslCertificate::alternateSubjectNames() is deprecated (but can be enabled via QT_DISABLE_DEPRECATED_BEFORE), use QSslCertificate::subjectAlternativeNames() instead. - QLibraryInfo::buildKey() has been removed. Likewise, the QT_BUILD_KEY preprocessor #define has also been removed. The build-key is obsolete and is no longer necessary. - QCoreApplication::translate() will no longer return the source text when the translation is empty. Use lrelease -removeidentical for optimization. - Qt::escape() is deprecated (but can be enabled via QT_DISABLE_DEPRECATED_BEFORE), use QString::toHtmlEscaped() instead. - QMetaType::construct() has been renamed to QMetaType::create(). - QTestLib: * The QTRY_VERIFY and QTRY_COMPARE macros have been moved into QTestLib. These macros formerly lived in tests/shared/util.h but are now provided by including the header. * The QTEST_NOOP_MAIN macro has been removed from the API. If a test is known at compile-time to be inapplicable for a particular build it should be omitted via .pro file logic, or the test should call QSKIP in the initTestCase() method to skip the entire test and report a meaningful explanation in the test log. * The DEPENDS_ON macro has been removed from the API. This macro did nothing and misled some users to believe that they could make test functions depend on each other or impose an execution order on test functions. * The QTest::qt_snprintf function has been removed from the API. This was an internal testlib function that was exposed in the public API due to its use in a public macro. Any calls to this function should be replaced by a call to qsnprintf(), which comes from the header. * The QTest::pixmapsAreEqual() function has been removed from the API. Comparison of QPixmap objects should be done using QCOMPARE, which provides more informative output in the event of a failure. * The QSKIP macro no longer has the "mode" parameter, which caused problems for calculating test metrics, as the SkipAll mode hid information about what test data was skipped. Calling QSKIP in a test function now behaves like SkipSingle -- skipping a non-data-driven test function or skipping only the current data row of a data-driven test function. Every skipped data row is now reported in the test log. - The QSsl::TlsV1 enum value was renamed to QSsl::TlsV1_0 . - QAccessible: * Internal QAccessible::State enum value HasInvokeExtension removed - QAccessibleInterface: * The "child" integer parameters have been removed. This moves the api to be closer to IAccessible2. This means several functions lose their integer parameter: text(Text t, int child) -> text(Text t), rect(int child) -> rect() setText(Text t, int child, const QString &text) -> setText(Text t, const QString &text) role(int child) -> role(), state(int child) -> state() relationTo(int child, const QAccessibleInterface *other, int otherChild) -> relationTo(const QAccessibleInterface *other) * Accessible-Action related functions have been removed. QAccessibleInterface subclasses are expected to implement the QAccessibleActionInterface instead. These functions have been removed: QAccessibleInterface::userActionCount, QAccessibleInterface::actionText, QAccessibleInterface::doAction - QAccessibleEvent also loses the child parameter. QAccessibleEvent(Type type, int child) -> QAccessibleEvent(Type type) QAccessibleEvent::child() removed. - QAccessibleActionInterface: * Refactored to be based on action names. All functions have been changed from using int parameters to strings. - QSound has been moved from QtGui to QtMultimedia - QTouchEvent: * The DeviceType enum and deviceType() have been deprecated due to the introduction of QTouchDevice. * The signature of the constructor has changed. It now takes a QTouchDevice pointer instead of just a DeviceType value. * TouchPointState no longer includes TouchPointStateMask and TouchPointPrimary. The primary flag is now stored together with other touch point flags and is accessible through TouchPoint::isPrimary() or TouchPoint::flags(). As a result the internally used state mask is no longer necessary. * QWidget *widget() has been removed and is replaced by QObject *target() in order to avoid QWidget dependencies. - QWindowSystemInterface: * The signature of all handleTouchEvent() variants have changed, taking a QTouchDevice* instead of just a DeviceType value. Platform or generic plug-ins have to create and register at least one QTouchDevice before sending the first touch event. * The event type parameter is removed from handleTouchEvent(). - The previously exported function qt_translateRawTouchEvent() has been removed. Use QWindowSystemInterface::handleTouchEvent() instead. - QAbstractEventDispatcher * The signature for the pure-virtual registerTimer() has changed. Subclasses of QAbstractEventDispatcher will need to be updated to reimplement the new pure-virtual 'virtual void registerTimer(int timerId, int interval, Qt::TimerType timerType, QObject *object) = 0;' * QAbstractEventDispatcher::TimerInfo is no longer a QPair. It is now a struct with 3 members: struct TimerInfo { int timerId; int interval; Qt::TimerType timerType; }; Reimplementations of QAbstractEventDispatcher::registeredTimers() will need to be updated to pass 3 arguments to the TimerInfo constructor (instead of 2). - QUuid * Removed implicit conversion operator QUuid::operator QString(), instead QUuid::toString() function should be used. **************************************************************************** * General * **************************************************************************** General Improvements -------------------- - The directory structure of the qtbase unit-tests has been reworked to more closely match the directory structure of the code under test. Integration tests have been moved to tests/auto/integrationtests. Third party components ---------------------- - **************************************************************************** * Library * **************************************************************************** QtCore ------ * drop a bogus QChar::NoCategory enum value; the proper QChar::Other_NotAssigned value is returned for an unassigned codepoints now. * layoutAboutToBeChanged is no longer emitted by QAbstractItemModel::beginMoveRows. layoutChanged is no longer emitted by QAbstractItemModel::endMoveRows. Proxy models should now also connect to (and disconnect from) the rowsAboutToBeMoved and rowsMoved signals. * The default value of the property QSortFilterProxyModel::dynamicSortFilter was changed from false to true. * QFileSystemWatcher is now able to return failure in case of errors whilst altering the watchlist in both the singular and QStringList overloads of addPath and removePath. QtGui ----- * Accessibility has been refactored. The hierachy of accessible objects is implemented via proper parent/child functions instead of using navigate which has been deprecated for this purpose. Table and cell interfaces have been added to qaccessible2.h * Touch events and points have been extended to hold additional information like capability flags, point-specific flags, velocity, and raw positions. QtWidgets --------- * QWidget::setInputContext() is removed. Input contexts are now platform specific. QtNetwork --------- * QHostAddress::isLoopback() API added. Returns true if the address is one of the IP loopback addresses. * QSslCertificate::serialNumber() now always returns the serial number in hexadecimal format. * The openssl network backend now reads the ssl configuration file allowing the use of openssl engines. QtOpenGL -------- QtScript -------- QTestLib -------- * [QTBUG-20615] Autotests can now log test output to multiple destinations and log formats simultaneously. **************************************************************************** * Database Drivers * **************************************************************************** **************************************************************************** * Platform Specific Changes * **************************************************************************** Qt for Linux/X11 ---------------- Qt for Windows -------------- * Accessibility framework uses IAccessible2 Qt for Mac OS X --------------- Qt for Embedded Linux --------------------- Qt for Windows CE ----------------- **************************************************************************** * Compiler Specific Changes * **************************************************************************** **************************************************************************** * Tools * **************************************************************************** - Build System - Assistant - Designer - Linguist - rcc - moc * [QTBUG-20785] The moc now has a -b option to #include an additional file at the beginning of the generated file. - uic - uic3 - qmake * QMAKE_MOC_OPTIONS variable is now available for passing additional parameters to the moc. - configure - qtconfig **************************************************************************** * Plugins * **************************************************************************** **************************************************************************** * Important Behavior Changes * **************************************************************************** - QPointer * QPointer itself is now deprecated, and the implementation of QPointer has been changed to use QWeakPointer. The old guard mechanism has been removed. This causes two slight changes in behavior when using QPointer: * When using QPointer on a QWidget (or a subclass of QWidget), previously the QPointer would be cleared by the QWidget destructor. Now, the QPointer is cleared by the QObject destructor (since this is when QWeakPointers are cleared). Any QPointers tracking a widget will NOT be cleared before the QWidget destructor destroys the children for the widget being tracked. * When constructing a QSharedPointer to take ownership of an object after a QPointer is already tracking the object. Previously, the shared pointer construction would not be affected by the QPointer, but now that QPointer is implemented using QWeakPoiner, constructing the QSharedPointer will cause an abort().
