Qt 5.14 introduces many new features and improvements as well as bugfixes
|
|
over the 5.13.x series. For more details, refer to the online documentation
|
|
included in this distribution. The documentation is also available online:
|
|
|
|
https://doc.qt.io/qt-5/index.html
|
|
|
|
The Qt version 5.14 series is binary compatible with the 5.13.x series.
|
|
Applications compiled for 5.13 will continue to run with 5.14.
|
|
|
|
Some of the changes listed in this file include issue tracking numbers
|
|

****************************************************************************
|
|
* Important Behavioral Change *
|
|
****************************************************************************
|
|
|
|
- [QTBUG-47644] WrapWord now correctly prefers line breaks between words
|
|
in Korean text. WrapAnywhere can still be used to get breaks between
|
|
syllables instead.
|
|
|
|
****************************************************************************
|
|
* Potentially Source-Incompatible Changes *
|
|
****************************************************************************
|
|
|
|
- qstringlist.h no longer includes qregexp.h.
|
|
- Prefixing Q_NAMESPACE with an export macro may no longer work. Use the
|
|
new Q_NAMESPACE_EXPORT macro for that use case.
|
|
|
|
****************************************************************************

|
|
|
|
- Added support of deduction guides for QPair
|
|
- Added new Qt::SplitBehavior, for use as eventual replacement for
|
|
QString::SplitBehavior.
|
|
- Added the new Q_NAMESPACE_EXPORT macro. It can be used just like
|
|
Q_NAMESPACE to add meta-object information to a namespace; however it
|
|
also supports exporting of such information from shared libraries.
|
|
- [QTBUG-15234] Qt installations on the host system can now be relocated,
|
|
i.e. moved to other directories.
|
|
|
|
- JSON:
|
|
* Added overloads of functions taking key strings as QStringView; in
|
|
QJsonObject, QJsonValue and QJsonDocument.
|
|
|
|
- QAtomicInteger:
|
|
* Added loadRelaxed() and storeRelaxed(), to be used as replacements of
|
|
load() / store().
|
|
|
|
- QAtomicPointer:
|
|
* Added loadRelaxed() and storeRelaxed(), to be used as replacements of
|
|
load() / store().
|
|
|
|
- QBasicTimer:
|
|
* QBasicTimer is now a move-only class. Copying is now deprecated and
|
|
will be removed in Qt 6.
|
|
* Added swap() member and free function.
|
|
|
|
- QByteArray::operator[]:
|
|
* Detach immediately, instead of deferring until modification via
|
|
the returned QByteRef.
|
|
* Deprecate reliance on its implicit resizing behavior. Support for
|
|
writing past the end of QByteArray shall be removed in a future
|
|
version of Qt.
|
|
|
|
- QCalendar:
|
|
* Added QCalendar to support diverse calendars, supported by
|
|
implementing QCalendarBackend.
|
|
* Added support for Julian and Milankovic calendars. These are enabled
|
|
by default, except in bootstrap builds.
|
|
* Added support for the Jalali (Persian or Solar Hijri) calendar,
|
|
controlled by feature jalalicalendar.
|
|
* Added support for the Islamic Civil calendar, controlled by feature
|
|
islamiccivilcalendar, with locale data that can be shared with other
|
|
implementations, controlled by feature hijricalendar.
|
|
|
|
- QChar:
|
|
* Added FormFeed (FF) special character.
|
|
|
|
- QCollator:
|
|
* Added support for QStringView.
|
|
* The default QCollator now uses the system's collation locale, rather
|
|
than the system locale itself.
|
|
|
|
- QDataStream:
|
|
* Enumerations can now be serialized through QDataStream without the
|
|
need of manually defining streaming operators.
|
|
|
|
- QDate:
|
|
* [QTBUG-64485] Added startOfDay() and endOfDay() methods to provide a
|
|
QDateTime at the start and end of a given date, taking account of any
|
|
time skipped by transitions, e.g. a DST spring-forward, which can lead
|
|
to a day starting at 01:00 or ending just before 23:00.
|
|
* Allow choice of calendar in various operations, with Gregorian
|
|
remaining the default.
|
|
|
|
- QDateTime:
|
|
* Invalid datetimes are now treated as equal and less than all valid
|
|
ones. They could previously be found equal to valid datetimes.
|
|
|
|
- QDir:
|
|
* Remove Windows specific long path markers when handling file paths
|
|
with native separators.
|
|
|
|
- QEasingCurve:
|
|
* QEasingCurve now properly streams all the data needed to QDataStream.
|
|
|
|
- QFileInfo:
|
|
* [QTBUG-75869] Introduced QFileInfo::isJunction() to detect NTFS Junctions
|
|
on Windows.
|
|
|
|
- QHash:
|
|
* Added range constructor.
|
|
|
|
- QJsonObject:
|
|
* Added insert(), remove(), and take() overloads taking QLatin1String.
|
|
|
|
- QLatin1Char:
|
|
* Comparison against char now works even in QT_NO_CAST_FROM_ASCII
|
|
builds.
|
|
|
|
- QLatin1Literal:
|
|
* The undocumented QLatin1Literal type alias for QLatin1String is now
|
|
deprecated. Use QLatin1String instead.
|
|
|
|
- QLatin1String:
|
|
* Added indexOf().
|
|
* Added contains().
|
|
* Added lastIndexOf().
|
|
|
|
- QLineF:
|
|
* added QLineF::intersects() as a replacement for QLineF::intersect()
|
|
|
|
- QLinkedList:
|
|
* Added range constructor.
|
|
|
|
- QList:
|
|
* Added range constructor.
|
|
|
|
- QLocale:
|
|
* The system locale now knows what to use for collation,
|
|
QLocale::system().collation().
|
|
* The NaN obtained when reading "nan" as a floating-point value is now
|
|
quiet rather than signaling.
|
|
* The system locale's UI languages list now includes, as for that of an
|
|
ordinary locale, the results of adding likely sub-tags from each
|
|
locale name, and of removing some, where this doesn't change which
|
|
locale is specified. This gives searches for translation files a
|
|
better chance of finding a suitable file.
|
|
|
|
- QMetaObject:
|
|
* [QTBUG-38876] Some internal members of the QMetaObject class have
|
|
changed types. Those members are not public API and thus should not
|
|
cause source incompatibilities.
|
|
|
|
- QMultiHash:
|
|
* Added range constructor.
|
|
|
|
- QMutex:
|
|
* Added QRecursiveMutex as a replacement of QMutex(QMutex::Recursive).
|
|
|
|
- QPoint/QPointF:
|
|
* Added transposed().
|
|
|
|
- QPointer:
|
|
* Added a free swap function.
|
|
|
|
- QSet:
|
|
* Added range constructor.
|
|
|
|
- QSharedPointer:
|
|
* Overloads of qSharedPointerObjectCast have been added to work on
|
|
std::shared_ptr.
|
|
* The swap overload for QSharedPointer in the std namespace has been
|
|
removed; a new overload has been added in the Qt namespace.
|
|
|
|
- QSize/QSizeF:
|
|
* Added grownBy(QMargin(F))/shrunkBy(QMargin(F)).
|
|
|
|
- QString:
|
|
* The behavior of operator[] to allow implicit resizing of the string
|
|
has been deprecated, and will be removed in a future version of Qt.
|
|
* QString::operator[] detaches immediately. Previously, the detach was
|
|
delayed until a modification was made to the string through the
|
|
returned QCharRef.
|
|
* QString::arg(QString, ..., QString) can now be called with more than
|
|
nine arguments, as well as with QStringViews.
|
|
|
|
- QString/QStringRef:
|
|
* The split functions now optionally take Qt::SplitBehavior.
|
|
|
|
- QStringList:
|
|
* Added range constructor.
|
|
* Added QStringView overloads of join(), filter(), and
|
|
replaceInStrings().
|
|
|
|
- QStringView:
|
|
* Added indexOf().
|
|
* Added contains().
|
|
* Added lastIndexOf().
|
|
* Deprecated the (undocumented) QStringViewLiteral macro. Just use u""
|
|
or QStringView(u"") instead.
|
|
|
|
- QStringView/QLatin1String:
|
|
* Added arg(), taking arbitrarily many strings.
|
|
|
|
- QTextStream:
|
|
* The NaN obtained when reading "nan" as a floating-point value is now
|
|
quiet rather than signaling.
|
|
|
|
- QTimeZone:
|
|
* [QTBUG-75565] The TZDB back-end now recognizes the contents of /etc/TZ
|
|
as a fall-back for $TZ (as used by uClibc).
|
|
|
|
- QVarLengthArray:
|
|
* Added range constructor.
|
|
* Added a qHash overload.
|
|
|
|
- QVariant:
|
|
* Fixed a bug that caused isNull() to be true after downcasting a
|
|
QObject* payload using convert().
|
|
|
|
- QVector:
|
|
* Added range constructor.
|
|
|
|
- QWeakPointer:
|
|
* The data() function has been deprecated.
|
|
* A swap overload has been added.
|
|
|
|
- QtGlobal:
|
|
* Add new macros QT_DEPRECATED_VERSION and QT_DEPRECATED_VERSION_X to
|
|
conditionally display deprecation warnings
|
|
* Added qExchange(), a drop-in for C++14's std::exchange()
|
|
|
|
- Windows:
|
|
* QSysInfo::prettyProductName() now returns a version including the
|
|
Windows 10 release id or Windows 7 build number respectively,
|
|
resembling the version string displayed by the winver tool.
|
|

|
|
* QtDBus *
|
|
****************************************************************************
|
|
|
|
- QDBusAbstractInterface:
|
|
* The call() and asyncCall() methods now accept more than eight QVariant
|
|
arguments.
|
|
|
|
- QDBusObjectPath:
|
|
* Added explicit cast operator to QVariant.
|

|
|
|
- QColor:
|
|
* Added QColorConstants, a namespace containing constexpr QColor
|
|
instances.
|
|
|
|
- A QColorSpace class has been added, and color spaces are now parsed from
|
|
PNG and JPEG images. No automatic color space conversion is done
|
|
however, and applications must request it.
|
|
- Added support for filtering Vulkan debug messages in QVulkanInstance.
|
|
This is especially useful for processing or suppressing messages from
|
|
the validation layers.
|
|
- Obsolete constructors and accessors in QWheelEvent now have proper
|
|
deprecation macros, and are no longer in use in any Qt modules.
|
|
What is left is intended to be compatible with planned changes in Qt 6.
|
|
|
|
- QFont:
|
|
* [QTBUG-77908] Fixed kerning error with certain fonts.
|
|
* [QTBUG-76239] Fixed an issue where application fonts would be parsed
|
|
multiple times, causing some unnecessary overhead when during
|
|
application startup.
|
|
* [QTBUG-46322] Resolving a font that just has a family set with
|
|
families set will prepend the family to the families so that it is
|
|
still the first preference for the font.
|
|
|
|
- QImage:
|
|
* [QTBUG-42540], [QTBUG-68787] Loading of image files having a file
|
|
name suffix for a different image file type has been
|
|
fixed. QImageReader will now ask the suffix format handler to
|
|
confirm the file contents (canRead()), and fall back to normal
|
|
file content recognition on failure. This implies a slight
|
|
behavior change in QImageReader::loopCount(), ::imageCount() and
|
|
::nextImageDelay(): For an unreadable file with a recognized
|
|
suffix, they would earlier return 0, while they now will
|
|
return -1, i.e. error, as per the documentation.
|
|
|
|
- QPainter:
|
|
* HighQualityAntialiasing and NonCosmeticDefaultPen are marked as
|
|
deprecated and don't have an effect anymore
|
|
|
|
- QTextDocument:
|
|
* [QTBUG-36152] CSS styling of table cell borders (styling <td> and <th>
|
|
elements) is now supported during HTML import and export, including
|
|
border-color, border-width and border-style. Setting the table's
|
|
border-width to a value >= 1 and enabling border-collapse will now draw
|
|
a simple, clean table grid (1px) with an outer border of the specified
|
|
width and color. A manual test was added, which allows editing HTML
|
|
with live preview.
|
|
* [QTBUG-43589] Fixed incorrect rounding of widths of variable-width
|
|
columns in tables, to avoid border drawing artifacts.
|
|
* [QTBUG-78318] QTextFrameFormat margins, padding and borders are now
|
|
scaled to device coordinates, and thus correctly sized on high-dpi
|
|
displays and printers.
|
|
* Markdown (CommonMark or GitHub dialect) is now a supported format for
|
|
reading into and writing from QTextDocument, via the setMarkdown() and
|
|
toMarkdown() functions. We do not guarantee that every markdown
|
|
document can be re-written exactly as it was read; but that does work
|
|
in many cases, and it's OK to report bugs about cases that don't work.
|
|
|
|
- Touch:
|
|
* [QTBUG-77142] When a stationary touchpoint contains some "interesting"
|
|
property change (pressure or velocity, so far), it is delivered normally.
|
|
|

|
|
* Added move contructor.
|
|
|
|
- QNetworkAccessManager:
|
|
* [QTBUG-69477] Don't fail when FTP does not implement the HELP command.
|
|
* Added setAutoDeleteReplies to QNetworkAccessManager to enable the
|
|
AutoDeleteReplyOnFinishAttribute attribute for all QNetworkRequests
|
|
that are passed to QNetworkAccessManager.
|
|
|
|
- QNetworkRequest:
|
|
* Added the AutoDeleteReplyOnFinishAttribute attribute to
|
|
QNetworkRequest, which makes QNetworkAccessManager delete the
|
|
QNetworkReply after it has emitted the "finished" signal.
|
|
* Add an ability to configure HTTP/2 protocol
|
|
|
|
- QSslKey:
|
|
* Key data is cleared as soon as possible when move-assigning.
|
|
|
|
- QSslSocket:
|
|
* [QTBUG-72016] Added runtime validation of the SSL private key when it
|
|
is loaded through a file path.
|
|
|

|
|
****************************************************************************
|

|
- QPSQL:
|
|
* [QTBUG-79033][QTBUG-79064] added support for PostgreSQL 12
|
|
|
|
- QSqlite:
|
|
* Updated to v3.30.1
|
|
|
|
- QSqlite2:
|
|
* Marked QSQLITE2 plugin as obsolete - it will be removed with Qt6
|
|
together with the QTDS plugin
|

|
|
|
|
- Comparison of QImage, QPixmap now checks for the device pixel ratio.
|
|
- It is now possible to perform static initialization before QApplication
|
|
instantiation by implementing a initMain() function in the test class.

|
|
|
|
- QActionGroup:
|
|
* Added new exclusionPolicy property. Set it to ExclusiveOptional to
|
|
allow unchecking the active checkable action in an exclusive group.
|
|
|
|
- QCalendarWidget:
|
|
* Allow choice of calendar, with Gregorian remaining the default.
|
|
|
|
- QComboBox:
|
|
* Two new signals textHighlighted() and textActivated() were added to
|
|
replace highlighted()/activated() QString overloads.
|
|
|
|
- QDateTimeEdit:
|
|
* Allow choice of calendar, with Gregorian remaining the default.
|
|
|
|
- QFileDialog:
|
|
* The widgets-based dialog now remembers the selected files when
|
|
navigating the history.
|
|
|
|
- QFormLayout:
|
|
* Honor the vertical expanding state of a widget inside a QFormLayout.
|
|
|
|
- QGraphicsWidget:
|
|
* Added QMarginsF overloads of setContentsMargins() and
|
|
setWindowFrameMargins().
|
|
|
|
- QGroupBox:
|
|
* [QTBUG-259389 Always disable children of a checkable, unchecked group
|
|
box before showing.
|
|
|
|
- QLabel:
|
|
* Markdown is now a supported textFormat for QLabel.
|
|
|
|
- QLayout:
|
|
* Prevent clipping of group box titles on macOS (and similar styles that
|
|
draw into layout margins)
|
|
|
|
- QLineEdit:
|
|
* Behavior change: now the editingFinished signal is emitted only once
|
|
after the line edit content was edited.
|
|
* The getTextMargins() member function has been deprecated in favor of
|
|
textMargins().
|
|
|
|
- QStyle:
|
|
* Style sheets now only use the part of the stylesheet font that it
|
|
knows about. The remaining will be resolved/inherited from the
|
|
context.
|
|
|
|
- QTextBrowser:
|
|
* Markdown is now a supported format. QTextBrowser::setSource() detects
|
|
the common file extensions (.md, .mkd and .markdown). In case it
|
|
cannot be detected that way, setSource() now takes an optional
|
|
ResourceType enum argument so that the type can be overridden.
|
|
QTextBrowser inherits all the QTextEdit features: if readOnly is set
|
|
to false, the user can perform the editing operations that QTextEdit
|
|
allows. If readOnly is set to true (the default), the user can click
|
|
Markdown hyperlinks to emit the anchorClicked() signal, as with HTML.
|
|
|
|
- QTextEdit:
|
|
* [QTBUG-75931] Added support for copy-pasting foreground brushes with
|
|
textures within same document.
|
|
* Markdown (CommonMark or GitHub dialect) is now a supported format,
|
|
via the markdown property. GitHub dialect is the default, and supports
|
|
all features such as hyperlinks, images, tables, lists, checklists, etc.
|
|
* If the text was loaded from a Markdown document that contains checkboxes,
|
|
the user can click on them to toggle the states. The cursor changes to
|
|
PointingHandCursor when the mouse is hovering over a checkbox.
|
|
|
|
- QTreeView:
|
|
* Don't emit clicked signal after a doubleClicked signal.
|
|
|
|
- QWidget:
|
|
* The getContentsMargins() member function has been deprecated in favor
|
|
of contentsMargins().

|
****************************************************************************
|
|
* Platform Specific Changes *
|
|
****************************************************************************
|
|
|
|
- Android
|
|
* Fixed an issue where an application installation would be irrecoverably
|
|
broken if power loss or a crash occurred during its first initialization
|
|
run.
|
|
* Make it easy to run Qt tests on Android. "$ make check" is all that's
|
|
needed to run a test on an Android device.
|
|
* Remove ant support from androiddeployqt
|
|
* Introduce "make apk" target, an easy way to create an apk.
|
|
* Android depends on NDK r20+
|
|
* Android multi arch build in one go, needed to support the new .aab
|
|
packaging format.
|
|
* -android-abis configure script parameter useful to compile Qt only for a
|
|
selected Android ABIs.
|
|
* Instead of bundling QML resources in assets and extracting them on first
|
|
start, Qt now creates an .rcc file and register it before invoking the
|
|
main function.
|
|
* Fixed regression that made it impossible for an application to use the
|
|
tap-and-hold gesture.
|
|
|
|
- Linux:
|
|
* Added a device spec for Raspberry Pi 4 (32-bit, V3D)
|
|
* Added a device spec for 64-bit i.MX8 systems (Vivante graphics stack)
|
|
|
|
- MinGW:
|
|
* [QTBUG-4155] Added a suffix to debug mode pkgconfig files.
|
|
* MinGW does not built with -debug-and-release mode anymore.
|
|
Instead, the binaries are built with -release -force-debug-info
|
|
-separate-debug-info.
|
|
|
|
- macOS:
|
|
* The drawableSize of Metal layers is no longer updated automatically on
|

window resize or screen change. Update the size manually in response to
|
|
resizeEvent(), or at the start of each frame, as needed.
|
|
|
|
- Mir:
|
|
* The Mir platform plugin has been removed: use the Wayland plugin when
|

|
|
request different faces of a font family after a specific type face
|
|
has been in use.
