| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - Qt is now compiled with qreal typedef'ed to double on all |
| platforms. qreal was a float on ARM chipsets before. This guarantees more |
| consistent behavior between all platforms Qt supports, but is binary |
| incompatible to Qt 5.1 on ARM. The old behavior can be restored by |
| passing -qreal float to configure. |
| - The supported date range in QDateTime has been reduced to about +/- 292 |
| million years, the range supported by the number of msecs since the Unix |
| epoch of 1 Jan 1970 as stored in a qint64, and as able to be used in the |
| setMSecsSinceEpoch() and toMSecsSinceEpoch() methods. |
| |
| - QUrl and QUrlQuery: |
| * [QTBUG-31660] QUrl no longer considers all delimiter characters |
| equivalent to their percent-encoded forms. Now, both classes always |
| keep all delimiters exactly as they were in the original URL text. |
| * [QTBUG-31660] QUrl no longer decodes %7B and %7D to "{" and "}" in the |
| output of toString() |
| * QUrl no longer supports QUrl::FullyDecoded mode in authority() and |
| userInfo(), nor QUrl::DecodedMode in setAuthority() and setUserInfo(). |
| * [QTBUG-31945] QUrl no longer decodes %23 found in the fragment to "#" |
| in the output of toString(QUrl::FullyEncoded) or toEncoded() |
| * QUrl now defaults to decoded mode in the getters and setters for |
| userName, password, host, topLevelDomain, path and fileName. This |
| means a '%' in one of those fields is now returned (or set) as '%' |
| rather than "%25". In the unlikely case where the former behavior was |
| expected, pass PrettyDecoded to the getter and TolerantMode to the |
| setter. |
| * QUrl now normalizes the path given in setPath, removing ./ and ../ and |
| duplicate slashes. |
| |
| - QWheelEvent has gained a "phase" attribute and may now be sent with |
| zero delta() in order to indicate beginning and end of transient |
| scrolling. |
| |
| - Mac OS X framework builds of Qt no longer contain a Unix-like include/ |
| directory; all headers are located in the frameworks. This may affect |
| 3rd party build systems not based on qmake or cmake. |
| |
| **************************************************************************** |
| * Platform deprecation notice * |
| **************************************************************************** |
| |
| - The support for the old implementation of QAtomicInt and |
| QAtomicPointer is deprecated in Qt 5.2 and will be removed in Qt |
| 5.3. Building with the following compilers or environments will not |
| be possible in Qt 5.3 or the build will suffer greatly in |
| performance, unless support is revived by writing new atomics code. |
| * Green Hills compiler for INTEGRITY |
| * Sun Studio compiler suite for Solaris |
| * IBM Visual Age compiler suite for AIX |
| * Kernel-mode VxWorks |
| |
| Developers interested in picking up support should contact the |
| development mailing list at development@qt-project.org for more |
| information. Note that those platforms are currently not tested. Most |
| likely, they have further problems than just the atomics code. |
| |
| **************************************************************************** |
| * Library * |
| **************************************************************************** |
| |
| QtCore |
| ------ |
| |
| - Added QCollator, a class to collate Unicode strings. |
| - Added QCommandLineParser, a class to parse command lines. |
| - Added QFileSelector, a class to select platform-specific file assets. |
| - Added QLoggingCategory and related functions for logging |
| - [QTBUG-23946] Fixed a bug that prevented Qt from being built in a |
| namespace on Mac OS X. |
| - Updated the locale database to CLDR 23.1 |
| - Added support for ARMv8 64-bit mode. |
| |
| - Metatype system (QMetaType & QVariant): |
| * Qt now handles metatypes automatically for std::vector, std::list, |
| std::pair and std::map |
| * The metatype system now supports registering explicit conversion |
| functions via QMetaType::registerConverter |
| * The metatype system now supports iteration over a container type via |
| QSequentialIterable and QAssociativeIterable |
| * Registering the same type name twice will now print only a warning (as |
| opposed to aborting the execution of the program) |
| |
| - Qt Containers: |
| * In debug mode, the Qt containers will now verify whether the iterators |
| passed to most mutating functions belong to the iterator in question. |
| * Fixed a number of bugs that would modify shared containers when calling |
| erase(), under corner-case conditions. |
| |
| - QtAlgorithms |
| With STL no longer being optional for building and using Qt, a number of parts |
| of QtAlgorithms no longer make sense, and have therefore been deprecated. |
| |
| Replacements are available in the STL, and generally have much better |
| performance, but are not instantly source-compatible in all cases. For |
| instance, specialization of qLess or qSwap means that a direct port to |
| std::sort from qSort may not be possible, as std::sort does not use any of |
| them; a possible workaround is explicitly passing a qLess functor to |
| std::sort: |
| |
| std::sort(container.begin(), container.end(), qLess<T>()); |
| |
| The functions in QtAlgorithms that have been deprecated, along with their |
| STL counterparts, are: |
| - qBinaryFind (std::binary_search / std::lower_bound) |
| - qCopy (std::copy) |
| - qCopyBackward (std::copy_backward) |
| - qEqual (std::equal) |
| - qFill (std::fill) |
| - qFind (std::find) |
| - qCount (std::count) |
| - qSort (std::sort) |
| - qStableSort (std::stable_sort) |
| - qLowerBound (std::lower_bound) |
| - qUpperBound (std::upper_bound) |
| - qLess (std::less) |
| - qGreater (std::greater) |
| |
| - QByteArray: |
| * Added QByteArray::Base64Url and QByteArray::OmitTrailingEquals flags |
| for QByteArray::toBase64 and fromBase64. |
| * [QTBUG-34694] Fixed a bug that would cause QByteArray to overflow some |
| size calculations. |
| |
| - QCoreApplication: |
| * [QTBUG-15379][QTBUG-30628] Fixed a bug that caused Qt to mis-parse a |
| command-line argument like -DKEY=\"VALUE\" on Windows. |
| |
| - QDateTime: |
| * [QTBUG-26161][QTBUG-29666] Fully implement support for Qt::TimeSpec of |
| Qt::OffsetFromUTC, added new methods for offsetFromUTC(), |
| toTimeSpec(), and toOffsetFromUTC(). |
| * Added convenience methods for fromMSecsSinceEpoch() and fromTime_t() |
| to take time spec to be used in returned datetime. |
| * Add method timeZoneAbbreviation() to return effective time zone |
| abbreviation. |
| * The debug datastream is now an ISO-like format instead of Qt::TextDate |
| * The Standard Time to Daylight Time transition for Qt::LocalTime is now |
| handled correctly. Any date set in the "missing" hour is now |
| considered invalid. All date math results that fall into the missing |
| hour will be automatically adjusted to a valid time in the following |
| hour. |
| * Added new method isDaylightTime() to return if the datetime is in |
| Daylight Time or not. |
| * Added support for a new Qt::TimeZone spec to be used with QTimeZone to |
| define times in a specific time zone. |
| * Added Qt::RFC2822Date format that can be passed to QDateTime and |
| QLocale formatters and parsers. |
| * Fixed a bug that caused QDate::toString() to return empty for dates |
| with years beyond 9999. |
| |
| - QFileSystemWatcher: |
| * [QTBUG-33211] Fixed a bug that caused QFileSystemWatcher to emit change |
| notifications with the wrong path on Linux. |
| |
| - QJson: |
| * [QTBUG-33229] The Writer and the Parser now fully accept non-character |
| unicode points. |
| * The Writer will no longer write inf, -inf and nan for infinites and NaN |
| values, which resulted in parsing back as strings. Instead, it will now |
| output null. |
| * The Writer now emits numeric values with full numeric precision. This |
| also allows QJson to support integer values with no loss of precision |
| up to 2^53. |
| |
| - QJsonValue: |
| * Added QJsonValue::toInt(). QJsonValue can store 32-bit signed integers |
| with no loss of precision. |
| |
| - QObject: |
| * New-style signal connections to functors, lambdas, and static functions |
| now works with a receiver object. The connection will be removed when |
| the either the sender or receiver objects are destroyed. |
| |
| - QPluginLoader: |
| * QPluginLoader will no longer load the plugins on Mac OS X and iOS |
| systems when scanning for valid plugins. |
| * Added QPluginLoader::staticPlugins(), which returns the list of |
| built-in plugins (linked to the executable and any loaded libraries). |
| |
| - QProcess: |
| * [QTBUG-32958] Fixed a bug that would cause QProcess to crash if |
| waitForStarted() were called after an unsuccessful start() |
| * Added QProcess::nullDevice(), which returns the platform's "blackhole" |
| device (/dev/null on Unix, NUL on Windows). This can be used with |
| QProcess::setStandardOutputFile. |
| * Added enum values QProcess::ForwardedOutputChannel and |
| QProcess::ForwardedErrorChannel, which allow for more fine-grained |
| control over which channel is forwarded and which one is captured. |
| * Added QProcess::ForwardedInputChannel, which allows for stdin to be |
| forwarded to this process's input. |
| * [QTBUG-32979] On Unix, QProcess now correctly forwards the siginfo_t |
| and context parameters of the signal handler to the previous handler. |
| |
| - QScopedPointer: |
| * Added QScopedPointerDeleteLater, a new class that can be used as the |
| second template to QScopedPointer and will call deleteLater() on the |
| pointer when it goes out of scope. |
| |
| - QSocketNotifier: |
| * Fixed a bug that caused socket notifiers not to be re-enabled after |
| they had been activated on BlackBerry. |
| |
| - QStandardPaths: |
| * QStandardPaths::enableTestMode is deprecated and is replaced by |
| QStandardPaths::setTestModeEnabled. |
| * Added QStandardPaths::GenericConfigLocation, which refers to a location |
| where applications can store config files to be shared with other |
| applications. |
| |
| - QThread: |
| * Added an advisory interrupt mechanism (QThread::requestInterruption and |
| QThread::isInterruptionRequested). |
| |
| - QThreadPool: |
| * Added method clear() to remove any queued QRunnables. |
| * Fixed a number of race conditions. |
| |
| - QTime: |
| * [QTBUG-30250] When calling QTime::toString(Qt::TextDate) and |
| QTime::toString(Qt::ISODate), milliseconds are now included in |
| the returned string. This also applies to |
| QDateTime::toString(Qt::TextDate) and |
| QDateTime::toString(ISODate). |
| * Added new methods fromMSecsSinceStartOfDay() to create a new QTime |
| from an msecs value, and msecsSinceStartOfDay() to return the QTime as |
| the number of msecs since the start of the day. |
| |
| - QTimeZone: |
| * Added new QTimeZone class to support time tone calculations using the |
| host platform time zone database and the Olsen time zone ID's. |
| |
| - QUrl: |
| * [QTBUG-33229] QUrl now fully accepts non-character unicode points; |
| they are encoded as percent characters; they can also be pretty |
| decoded |
| * Added QUrl::RemoveFilename flag which can be passed to path(), |
| authority() and toString() and will cause the filename part of the path |
| (the contents after the last '/') to be removed. |
| * Added QUrl::fileName(), which returns just the filename part of the |
| path. |
| * Added QUrl::NormalizePathSegments flag, which will cause QUrl to |
| remove "/./" or "/../" sequences as much as possible. It will not |
| remove "/../" from the beginning of the path. |
| * Added QUrl::adjusted(), which returns a new QUrl with certain parts of |
| the original URL removed or normalized. |
| * Added QUrl::matches(), which can be used to compare parts of two URLs |
| or to compare two URLs after normalization. |
| |
| - QUtf8: |
| * [QTBUG-33229] UTF-8 now accepts non-character unicode points; these |
| are not replaced by the replacement character anymore |
| |
| - QVariant: |
| * Fixed QVariant::canConvert with longlong |
| * Variant containing enum types can now be converted to integer |
| * [QTBUG-33981] Fixed a bug that would cause QPolygonF to be saved or |
| loaded incorrectly in QDataStream. |
| |
| QtDBus |
| ------ |
| |
| - Improved error handling so as to give more feedback to the developer when |
| certain marshalling or demarshalling actions fail. |
| - [QTBUG-27809] Fixed some race conditions related to delivering method |
| reply deliveries. |
| - Fixed a bug that made non-slot invokables not get listed in the |
| auto-generated introspections. |
| |
| QtDeclarative |
| ------------- |
| |
| - ColorDialog: |
| * Added currentColor property. |
| |
| - [QTBUG-32928] ShortcutOverride events now work for QQuickItem |
| subclasses |
| |
| QtGui |
| ----- |
| |
| - Accessibility classes are now public allowing accessibility |
| information for custom widgets/QQuickItems |
| |
| - Session Management: |
| * [QTBUG-28228] The new QPlatformSessionManager class brings back |
| the session management functionality. It allows the |
| implementation of platform specific behavior related to session |
| management. For platform that don't support this feature the |
| default behavior has not changed. Both X11 and Windows session |
| management are supported. |
| |
| - QPolygonF: |
| * When a QVariant holds a QPolygonF() then it will be correctly seen as |
| a null QVariant. |
| |
| - QImage: |
| * Added three byte-ordered RGBA8888 format that simplifies interaction |
| with OpenGL and other technologies that internally using RGBA formats. |
| |
| - [QTBUG-27349] Reintroduced command line argument for positioning |
| windows (-geometry on X11, -qwindowgeometry on other platforms) |
| |
| - [QTBUG-28832] Fixed regression from Qt 4 when using |
| QTextOption::ShowLineAndParagraphSeparators. |
| |
| QtNetwork |
| --------- |
| |
| - API was added to store and resume TLS session tickets. |
| - The minimum support openssl version has been increased to openssl |
| 1.0. The code to support older versions has not been removed, but is no |
| longer supported. |
| - An off-by-one error in NTLM proxy authentication has been fixed. |
| - Various improvements to reduce the memory used by qtnetwork have been |
| made. |
| - Improved support for HTTP proxy authentication. |
| - Support for preconnecting to servers before making HTTP and HTTPS |
| connections. This allows for much reduced latency when the hosts to be |
| connected to are known. |
| |
| QtPrintSupport |
| -------------- |
| |
| - QPrintDialog: |
| * Added support for setting CUPS job options in the print dialog. |
| * Added support for setting CUPS Banner pages in the print dialog. |
| * Added support for setting CUPS Page Set (even/odd pages only) in the |
| print dialog. |
| * Added support for setting CUPS Pages Per Sheet and Pages Per Sheet |
| Layout options |
| * Added CUPS server-side print range support for apps that can't support |
| print range option themselves |
| |
| QtSql |
| ----- |
| |
| Changes in Qt 5.1.0 (missing from released changelog dist/changes-5.1.0) |
| - [QTBUG-28088] Remove dependency of DB driver headers on qsqlcachedresult_p.h. |
| - Deprecate QSqlError setters. The constructor is sufficient, since it has |
| a parameter for each member variable. |
| - Rename the SQL driver header files to _p.h (make private) |
| The drivers were never public API. They were exposed by mistake in |
| public headers. What's more, they have #include'd a private header |
| (qsqlcachedresult_p.h) since at least Qt 4.5.1. That means no one used |
| those headers in Qt 4 (private headers weren't installed then) and |
| it's unlikely anyone did in 5.0. |
| - ODBC: Implemented lastInsertId() for some ODBC compatible databases. |
| - PSQL: Make lastInsertID work for tables without OIDs. |
| - [QTBUG-14904] SQLITE: Fix for Sql query aliases with dots |
| - [QTBUG-2192] ODBC: fix loss of milliseconds when binding QDateTime |
| - [QTBUG-30076] PSQL: escape backslashes only when server requires it |
| IMPORTANT: Applications that implemented their own workarounds must be |
| updated to avoid misbehavior and SQL injection vulnerabilities. |
| - [QTBUG-10569] ODBC: fixed QODBCResult::exec() return value for DELETE |
| operations when no rows are affected. |
| - ODBC: Fixed loss of column metadata on SQL_NO_DATA. |
| - QSqlTableModel: expose methods for getting primary values. |
| - ODBC: Fixed possible cause of spurious errors (commit af35ee291a1bbbc8) |
| |
| Changes in Qt 5.2.0 |
| - [QTBUG-29261] IBASE: Construct a valid QTime when creating timestamps for |
| iBase SQL driver. |
| - [QTBUG-33389] PSQL: Format QDateTime following ISO8601. |
| - Add QSQLITE_OPEN_URI option to QSQLITE driver |
| |
| QtWidgets |
| --------- |
| |
| - Added class QKeySequenceEdit. |
| - Added QMaxCocoaViewContainer and QMacNativeWidget classes. |
| - [QTBUG-1016] Added API to control tool tip timing via: |
| * new QToolTip::showTip() overload |
| * QWidget::toolTipDuration() property. |
| * QStyle::SH_ToolTip_WakeUpDelay and SH_ToolTip_FallAsleepDelay |
| style hints. |
| - [QTBUG-30255] Fixed a bug where spans across empty cells in a grid |
| layout got broken. |
| - [QTBUG-31569] WA_QuitOnClose now works even if there are other |
| windows that don't have it set. |
| - [QTBUG-32788] Properly handles Qt::WidgetWithChildrenShortcut |
| shortcuts in MDI subwindows now. |
| - [QTBUG-33078] QWidget::setWindowOpacity() now works when called |
| before QWidget::show(). |
| - [QTBUG-33104] Fixed a bug where layout items with a Preferred size |
| policy would be treated as fixed size, if mixed with Expanding |
| items having maximumSize set. |
| - [QTBUG-33247] Changed accessible trees and tables to always expose |
| hidden headers, instead of only exposing the visible headers. |
| - [QTBUG-34007] Fixed a crash in tablet support. |
| - Fixed a bug where the maximum size hint of a layout with spans was |
| wrong. |
| - Item delegates now cycle through all three states of tri-state |
| checkboxes, the same way QCheckBox itself does. |
| |
| - QAbstractItemView: |
| * [QTBUG-7232] In ItemViews scrollbars will now by default only |
| scroll 1 pixel when scrollMode is set to scrollPerPixel. That is |
| it will (when scrollMode is scrollPerPixel) do what is stated in |
| the documentation, and no longer automatically adjust the |
| scrollbar's singleStep. The user can now control that value. |
| |
| - QAbstractScrollArea: |
| * QAbstractScrollArea now has a SizeAdjustPolicy. If it is set to |
| AdjustToContents it will make use of the protected viewportSizeHint() |
| virtual function. This function returns a suggested size based on |
| contents. Note that although the viewportSizeHint() virtual function |
| was reserved in 5.0, user code was not supposed to be overriding it |
| (as the function was private and undocumented). Code that was |
| overriding viewportSizeHint() needs to be recompiled against 5.2 for |
| this feature to work correctly. |
| |
| - QButtonGroup: |
| * [QTBUG-14857] Added buttonToggled() signals. |
| |
| - QColorDialog: |
| * Added a web color QLineEdit. |
| * [QTBUG-14332] Added a screen color picker button. |
| * [QTBUG-31998] Does no longer create widgets when using the |
| platform dialog. |
| * [QTBUG-32054] Fixed a bug with keyboard navigation. |
| |
| - QComboBox: |
| * [QTBUG-31146] Fixed selection of items with identical text in |
| popup completion. |
| * Added currentData() convenience function which allows to retrieve |
| the user data set for the current item. |
| |
| - QCompleter: |
| * [QTBUG-3414] Added filterMode property. |
| * The activated() signal now passes invalid indexes instead of |
| random bogus ones when falling back to the completion prefix. |
| |
| - QDesktopWidget: |
| * [QTBUG-32567] Fixed emission of workAreaResized() signal. |
| |
| - QDialogButtonBox: |
| * Added a (StandardButtons,QWidget*) constructor. |
| |
| - QDockWidget: |
| * [QTBUG-31044] The position of a dock widget is now kept when |
| undocking. |
| * [QTBUG-32260] Fixed a bug where visibilityChanged was signaled |
| wrongly in certain multi-screen setups. |
| |
| - QFileDialog: |
| * setDefaultSuffix() now removes leading dot characters. |
| * Introduced DontUseCustomDirectoryIcons. This improves the file |
| dialog performance under Windows for the case where there are |
| lots of folders. Went from taking 60 seconds to 2 seconds, on a |
| SDCard with 10k folders. |
| * Added setMimeTypeFilters() for mimetype-based filtering, as an |
| alternative to pattern matching. |
| * Fixed removing of directories containing hidden or system files. |
| * Added QUrl-based API for remote files. |
| * [QTBUG-13182] Improved performance on Windows by |
| + not resolving NTFS symlinks (15x speedup on pessimistic |
| workloads) and |
| + using extensions over calling GetFileAttributesEx() in certain |
| cases. |
| * [QTBUG-29403] Fixed potential crash in destructor of |
| ~QFileInfoGather in threaded applications. |
| * [QTBUG-34132] QFileDialog does no longer instantiate widgets if a |
| native dialog will be used instead. Therefore some accessors |
| which previously returned unused objects will now return null. |
| As before, you can set the DontUseNativeDialog option to ensure |
| that widgets will be created and used instead. |
| * [QTBUG-33039] Does no longer create widgets when using the |
| platform dialog. |
| |
| - QFontComboBox: |
| * [QTBUG-1573] Made QFontComboBox locale-sensitive. |
| |
| - QFontDialog: |
| * Now has finer-grained control over the types of fonts listed, |
| similar to what QFontComboBox already had. |
| |
| - QGestureManager |
| * Now supports Mac OS X native gestures. |
| |
| - QGraphicsView etc |
| * Fixed a crash in QGraphicsProxyWidget. |
| * [QTBUG-8061] Allow handling of mouseDoubleClickEvent in |
| QGraphicsItems. |
| * [QTBUG-19036] Make QGraphicsScene::items(QPointF) work using |
| Qt::{Contains,Intersets}ItemBoundingRect with items that contain |
| the point in the bounding rectangle, but not their (custom) |
| shape. |
| * [QTBUG-29945] Fixed drop-shadow and blur effects when using a |
| QGLWidget viewport. |
| |
| - QGroupBox: |
| * [QTBUG-33610] The check indicator of a checkable group box is no |
| longer clipped when using a small title font. |
| |
| - QHeaderView: |
| * Reduced memory usage by 33%. |
| * [QTBUG-4346] A maximumSize for sections has been introduced. The |
| maximum section size is by default the largest possible section |
| size which in Qt 5.2 has been limited to 1048575 pixels. |
| * [QTBUG-32203] Fixed a painting bug involving hidden and reordered |
| sections. |
| |
| - QInputDialog: |
| * Added getMultiLineText static method. |
| |
| - QLayout: |
| * Added replaceWidget() function. |
| |
| - QLineEdit: |
| * [QTBUG-32061] The cursor is now positioned correctly in an empty |
| line edit with placeholder text. |
| * Keep placeholderText visible when focused, until text is added. |
| * Context-menu actions now have icons. |
| * Made it possible to add side widgets. |
| * Made it possible to add a clear button commonly used for item |
| view filtering as a side widget |
| |
| - QListView: |
| * [QTBUG-1180] Dragging an item outside the QListView in icon mode |
| no longer loses the icon. Also fixed a bug where under certain |
| conditions code overriding QAbstractItemView::viewOptions() would |
| not be called. |
| * [QTBUG-21433] Fixed content size calculation when either |
| horizontal or vertical scroll bar policy is always off. |
| |
| - QMacStyle: |
| * [QTBUG-31668] Fixed a case where multiple auto-default button |
| animations were running in parallel on OS X |
| |
| - QMainWindow: |
| * Added takeCentalWidget() function. |
| |
| - QMenu: |
| * Added QMenu::toNSMenu() conversion function (Mac only) |
| * Added QMenu::setAsDockMenu() and qt_mac_set_doc_menu(QMenu *menu) |
| functions (Mac only). |
| * [QTBUG-31664] Moving the mouse over a menu separator now closes |
| any open sub menus. |
| |
| - QMenuBar: |
| * [QTBUG-32807] Menus now close again on second click. |
| * Added QMenuBar::toNSMenu() conversion function (Mac only) |
| |
| - QMessageBox: |
| * May use native message boxes on some platforms now. |
| * setDetailedText() now works after show(). |
| * [QTBUG-2450] Added setCheckBox() function. |
| * [QTBUG-6731] It is now possible to select some or all text from a |
| QMessageBox and copy it to the clipboard. |
| |
| - QScrollBar: |
| * Transient scrollbars are now properly shown when starting |
| two-finger scrolling on OS X. |
| |

| * Added a retainSizeWhenHidden attribute. |
| |
| - QSpinBox: |
| * Values can now be displayed in different bases |
| (cf. displayIntegerBase property) |
| * [QTBUG-31602][QTBUG-34305] Fixed size calculation when |
| stylesheets are used. |
| |
| - QSplashScreen: |
| * Added message(), a getter for the currently displayed message. |
| |
| - QSplitter: |
| * Now gets the default value of opaqueResize property from (new) |
| QStyle::SH_Splitter_OpaqueResize styleHint. |
| |
| - QStyle: |
| * Added SH_ToolTip_WakeUpDelay and SH_ToolTip_FallAsleepDelay. |
| * Fixed SH_ItemView_ActivateItemOnSingleClick not being retrieved |
| correctly from the platform theme. |

| **************************************************************************** |
| * Platform Specific Changes * |
| **************************************************************************** |
| |
| |
| Android |
| ------- |
| |
| - Project structure and deployment has changed with the introduction of |
| androiddeployqt. Source and build files are no longer mixed, and the |
| build files for the APK package should not be touched. Customizing |
| the build files is possible. Read the documentation for androiddeployqt |
| for more information. |
| - Status bar visibility is now controlled by Qt, so the window state will |
| override settings in the AndroidManifest.xml. The default is still to |
| show the status bar (QWindow::showMaximized()). Use |
| QWindow::showFullScreen() to hide it. |
| - Implemented support for accessibility on Android. |
| - Implemented support for native action bar backend for menu bars in |
| Qt Quick Controls and Qt Widgets. |
| - Implemented support for native popup menus and comboboxes in Qt Quick |
| Controls. |
| - Implemented support for native message boxes in Qt Widgets. |
| - Several improvements to handling dialogs and multiple top-level |
| windows in Qt Widgets. |
| - Implemented automatic inclusion of necessary permissions in manifest |
| when linking against Qt Multimedia. |
| - Fixed crash on startup when running on Android 4.4. |
| - Add requirement for Android SDK version 13 or higher for building |
| Qt application. Note that this is for building only. The application |
| can still be targeted for devices with SDK versions 9 and up. |
| - Default to target SDK version 14 to disable overflow button in |
| system navigation. |
| - New module: Qt Android Extras. Contains convenience APIs for using |
| JNI, and will in the future include support for Android-specific |
| features which do not fit in a cross-platform API. |
| - Implemented support for thread-affinity in qrand() functions. |
| - Fixed several problems with predictive text in soft keyboard. |
| - Made several improvements to stability. |
| - Implemented support for camera and low-latency audio in Qt Multimedia. |
| - Fixed driver-specific bugs in text rendering in Qt Quick 2. |
| - Added preference in default manifest for installing applications to |
| external storage if possible. |
| - Fixed delivery of key press event for the Back key. |
| - Fixed race condition when showing a window in full screen which would |
| cause it to not be maximized. |
| - Fixed input method hints. |
| - Made font point sizes compatible with the interpretation of point |
| sizes on iOS to ease sharing code between the two platforms. |
| - Added support for QAmbientTemperatureSensor, QPressureSensor |
| and QProximitySensor to Qt Sensors. |
| - Removed dependency on Qt Widgets in default build of Qt Quick Controls. |
| |
| OS X |
| ---- |
| |
| - Added QMaxCocoaViewContainer and QMacNativeWidget classes. |
| - Qt for OS X is now identified by the macro Q_OS_OSX. This complements the |
| existing Q_OS_DARWIN macro (which identifies the open source kernel and |
| could identify non-Apple products) and Q_OS_MAC, which is defined for |
| both OS X and iOS. The old macro Q_OS_MACX is now deprecated. |
| - Qt no longer complains about new versions of OS X that haven't been |
| released yet. This will allow Qt 5.2 and future versions to build on |
| future versions yet to be released. Note that those versions are not |
| supported until official announcement by the Qt Project. |
| - Added a number of functions to QtCore to convert to and from |
| CFString/NSString and QString, CFURL/NSURL and QUrl. |
| - QGestureManager now supports Mac OS X native gestures. |
| - Added QMenu::setAsDockMenu(), QMenu(Bar)::toNSMenu(), |
| qt_mac_set_doc_menu() functions. |
| - [QTBUG-26722] The QWizard default background pixmap works again. |
| |
| BlackBerry |
| ---------- |
| |
| - Cover windows (aka active frames) are now supported. Cover windows must |
| have the Qt::CoverWindow flag set. They are shown when the application |
| is minimized. |
| |
| Windows |
| ------- |
| |
| - [QTBUG-33409][QTBUG-8764][QTBUG-10032] Fixed virtual key mapping on |
| Windows. |
| - QCoreApplication::arguments() changed the handling of single quotes, double quotes |
| and the backslash character, in order to match what argv[] contains. |
| In particular, single quotes are no longer removed from the argument string. |
| (QTBUG-15379, QTBUG-30628) |
| |
| X11 |
| --- |
| |
| - [QTBUG-31762] Fix position of system tray icon (except Unity) |
| - [QTBUG-27349] Reintroduced command line argument for positioning |
| windows (-geometry) |
| |
| **************************************************************************** |
| * Tools * |
| **************************************************************************** |
| |
| - configure |
| |
| * Added option to disable the QtMultimedia WMF backend |
| * [Unix] Added option to build with gcov support |
| * Added -extprefix option to support Qt installing into a different |
| location than the on-device -prefix within the -sysroot. |
| * [QTBUG-33584][Unix] Fixed parsing of -device-option with equal signs. |
| |
| - cmake config files |
| |
| * [QTBUG-33145] Fixed usage of non-QtBase modules with Qt compiled from |
| source tarballs. |
| * [QTBUG-33223] Fixed header file location on multi-arch systems. |
| * Added support for automatic packaging of Qt plugins with cpack. |
| |
| - qmake |
| |
| * [QTBUG-491] Added saner approach to debug/release path rewriting. |
| * Added the parseJson() function. |
| * Added "osx" scope as an alias for "macx". Note that matching on the |
| makespec is generally deprecated - use "linux", "gcc", etc. |
| * Added support for .qmake.stash files which are really *just* caches. |
| * [Xcode] Added support for QMAKE_PRE_LINK and QMAKE_POST_LINK. |
| * [QTBUG-31129] Added installation of PDB files for dlltarget. |
| * [QTBUG-28102] Added support for querying disabled Qt features. |
| * Removed macx-clang-libc++* makespecs. libc++ is now handled automatically. |
| * [QTBUG-32912][MSVS] Fixed moc not being run in case of DBUS_ADAPTORS or |
| DBUS_INTERFACES being present. |
| * [QTBUG-30644] Fixed unsatisfied requires() breaking recursive targets. |
| * [QTBUG-31204] Fixed extra compilers not finding their inputs. |
| * [QTBUG-32885][MSVS] Made it possible to disable debug information. |
| * [QTBUG-33446][MSVS] Fixed generation of VS2010+ solution files. |

| |
| - moc |
| * Porting moc to QCommandLineParser has changed one specific option in its |
| command line handling: using the -f option without argument |
| is not supported anymore (it wasn't necessary, since including the header |
| file is the default behavior). |
