2012-12-18 15:28:09 +00:00
|
|
|
- The Qt 3 support module and all related code was removed.
|
|
|
|
|
|
2012-12-11 20:06:31 +00:00
|
|
|
- QAtomicInt's and QAtomicPointer's non-atomic convenience methods
|
|
|
|
|
(i.e., operator=, operator int / operator T*, operator!, operator==,
|
|
|
|
|
operator!= and operator->) have been removed as they did implicit
|
|
|
|
|
loads and stores of unspecified memory ordering. Code dealing with
|
|
|
|
|
is expected to use load(), loadAquire(), store() and storeRelease()
|
|
|
|
|
as necessary instead.

|
|
2012-04-24 21:57:42 +00:00
|
|
|
- QObject
|
|
|
|
|
* The signatures of the connectNotify() and disconnectNotify() functions
|
|
|
|
|
have changed. The functions now get passed a QMetaMethod that identifies
|
|
|
|
|
the signal, rather than a const char *.
|
|
|
|
|
|
2011-06-27 14:05:22 +00:00
|
|
|
- QSslCertificate::subjectInfo() and QSslCertificate::issuerInfo() now
|
|
|
|
|
return a QStringList instead of a QString
|
|
|
|
|
|
2011-11-11 23:08:42 +00:00
|
|
|
- QSslCertificate::isValid() has been deprecated. Originally it only checked
|
|
|
|
|
the certificate dates, but later checking for blacklisting was added. Now
|
|
|
|
|
there's a more specific QSslCertificate::isBlacklisted() method.
|
|
|
|
|
|
2011-06-28 13:08:12 +00:00
|
|
|
- Unite clipping support has been removed from QPainter. The alternative is
|
|
|
|
|
to unite QRegion's and using the result on QPainter.
|
2011-06-27 14:05:22 +00:00
|
|
|
|
2011-07-21 16:47:26 +00:00
|
|
|
- QLibrary::resolve() now returns a function pointer instead of a void
|
|
|
|
|
pointer.
|
|
|
|
|
|
2011-08-03 16:36:55 +00:00
|
|
|
- QSslCertificate::alternateSubjectNames() is deprecated (but can be enabled
|
|
|
|
|
via QT_DISABLE_DEPRECATED_BEFORE), use
|
|
|
|
|
QSslCertificate::subjectAlternativeNames() instead.
|
|
|
|
|
|
2011-08-31 12:23:42 +00:00
|
|
|
- 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 The build-key is obsolete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.
|
|
|
|
|
|
2011-09-19 18:26:25 +00:00
|
|
|
- QCoreApplication::translate() will no longer return the source text when
|
|
|
|
|
the translation is empty. Use lrelease -removeidentical for optimization.
|
2012-01-10 09:13:55 +00:00
|
|
|
|
2012-08-19 09:42:08 +00:00
|
|
|
- QTranslator subclasses need to adjust the signature of the virtual method
|
|
|
|
|
translate() in order to add the "int n = -1" argument.
|
|
|
|
|
|
2012-01-31 17:31:58 +00:00
|
|
|
- QString and QByteArray constructors that take a size argument will now treat
|
|
|
|
|
negative sizes to indicate nul-terminated strings (a nul-terminated array of
|
|
|
|
|
QChar, in the case of QString). In Qt 4, negative sizes were ignored and
|
|
|
|
|
result in empty QString and QByteArray, respectively. The size argument to
|
|
|
|
|
those constructors now has a default value of -1, thus replacing the separate
|
|
|
|
|
constructors that did the same.
|
|
|
|
|
|
2011-09-29 11:31:39 +00:00
|
|
|
- Qt::escape() is deprecated (but can be enabled via
|
|
|
|
|
QT_DISABLE_DEPRECATED_BEFORE), use QString::toHtmlEscaped() instead.
|
2011-09-19 18:26:25 +00:00
|
|
|
|
2012-01-20 10:22:09 +00:00
|
|
|
- QBool is gone. QString::contains, QByteArray::contains, and QList::contains
|
|
|
|
|
used to return an internal QBool class so that the Qt3 code
|
|
|
|
|
"if (a.contains() == 2)" wouldn't compile anymore. Such code cannot exist
|
|
|
|
|
in Qt4, so these methods return a bool now. If your code used the undocumented
|
|
|
|
|
QBool, simply replace it with bool.
|
|
|
|
|
|
2012-12-06 09:47:59 +00:00
|
|
|
- The old macros TRUE and FALSE have been removed, use true and false instead.
|
|
|
|
|
|
2012-02-24 21:27:32 +00:00
|
|
|
- qIsDetached<> has been removed without replacement.
|
|
|
|
|
|
2012-09-20 13:06:11 +00:00
|
|
|
- The return type of QFlags<Enum>::operator int() now matches the Enum's underlying
|
|
|
|
|
type in signedness instead of always being 'int'. This was done in order to allow
|
|
|
|
|
QFlags over enums whose underlying type is unsigned (Qt::MouseButton is one such
|
|
|
|
|
enum).
|
|
|
|
|
|
2012-02-03 11:54:25 +00:00
|
|
|
- QMetaType:
|
|
|
|
|
* QMetaType::construct() has been renamed to QMetaType::create().
|
|
|
|
|
* QMetaType::unregisterType() has been removed.
|
2012-08-15 14:46:36 +00:00
|
|
|
* QMetaType now records if the type argument inherits QObject. This
|
|
|
|
|
can be used in scripting APIs, so that custom QObject subclasses
|
|
|
|
|
are treated as QObject pointers. In QtScript for example, this can
|
|
|
|
|
mean that QScriptValue.isQObject can be true where it was false before.
|
2012-07-19 12:33:28 +00:00
|
|
|
* QMetaType::QWidgetStar has been removed. Use qMetaTypeId<QWidget*>()
|
|
|
|
|
or QVariant::canConvert<QWidget*>() as appropriate.
|
2011-10-06 11:25:58 +00:00
|
|
|
|
2012-03-20 18:27:02 +00:00
|
|
|
- QMetaMethod:
|
|
|
|
|
* QMetaMethod::signature() has been renamed to QMetaMethod::methodSignature(),
|
|
|
|
|
and the return type has been changed to QByteArray. This was done to be able
|
|
|
|
|
to generate the signature string on demand, rather than always storing it in
|
|
|
|
|
the meta-data.
|
|
|
|
|
* QMetaMethod::typeName() no longer returns an empty string when the return
|
|
|
|
|
type is void; it returns "void". The recommended way of checking whether a
|
|
|
|
|
method returns void is to compare the return value of QMetaMethod::returnType()
|
|
|
|
|
to QMetaType::Void.
|
2012-02-18 22:16:24 +00:00
|
|
|
|
2012-04-13 12:52:34 +00:00
|
|
|
- QVariant:
|
|
|
|
|
* Inconsistent constructor taking Qt::GlobalColor and producing QVariant(QColor)
|
|
|
|
|
instance was removed. Code constructing such variants can be migrated by
|
|
|
|
|
explicitly calling QColor constructor. For example from "QVariant(Qt::red)"
|
|
|
|
|
to "QVariant(QColor(Qt::red))"
|
2012-09-28 15:22:21 +00:00
|
|
|
* Similarly, implicit creation of QVariants from enum values Qt::BrushStyle,
|
|
|
|
|
Qt::PenStyle, and Qt::CursorShape have been removed. Create objects explicitly
|
|
|
|
|
or use static_cast<int>(Qt::SolidLine) to create a QVariant of type int with
|
|
|
|
|
the same value as the enum.
|
2012-04-13 12:52:34 +00:00
|
|
|
|
2012-11-23 10:18:11 +00:00
|
|
|
- QLocale:
|
|
|
|
|
* The historical language and country names were updated to their modern values,
|
|
|
|
|
some deprecated names were dropped or mapped to their modern alternatives.
|
|
|
|
|
|
2011-10-28 02:04:53 +00:00
|
|
|
- QTestLib:
|
testlib: Count passes, fails and skips consistently.
For data-driven tests, testlib previously counted one fail or skip for
each data row that failed or skipped, while it counted only one pass
for a test function where all rows passed and counted no passes for a
test function where some rows passed and some rows failed. A similar
problem also existed for benchmark tests, which could run multiple
iterations of the same test, with each fail and skip being counted but
only a single pass being counted for the entire series of iterations.
This commit makes testlib count one pass, fail or skip for each data
row. Test functions that are not data-driven count one result for the
test function, as before. Benchmark tests count one pass, fail or skip
per iteration.
A side-effect of this change is that the test output in plain text, xml
and light xml formats now shows a result for every data row and
benchmark iteration executed, allowing post-processors to correctly
calculate the total number of tests executed. Previously, individual
rows were not shown in the test output if they passed, making such
calculations impossible.
The only change to the xunitxml output format is to correct a bug where
no test result was recorded for a test function if the last data row
was skipped and all other rows passed -- in which case the overall
result should be a pass. Note that there is also a pre-existing bug
in the xunit logger, where no result is reported if all rows are
skipped; that bug is unaffected by this commit.

2012-02-02 07:08:44 +00:00
|
|
|
* The plain-text, xml and lightxml test output formats have been changed to
|
|
|
|
|
show a test result for every row of test data in data-driven tests. In
|
|
|
|
|
Qt4, only fails and skips were shown for individual data rows and passes
|
|
|
|
|
were not shown for individual data rows, preventing accurate calculation
|
|
|
|
|
of test run rates and pass rates.
|
2011-10-28 02:04:53 +00:00
|
|
|
* 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
|
2012-01-10 09:13:55 +00:00
|
|
|
by including the <QtTest/QtTest> header. In addition,
|
|
|
|
|
QTRY_VERIFY_WITH_TIMEOUT and QTRY_COMPARE_WITH_TIMEOUT are provided,
|
|
|
|
|
allowing for specifying custom timeout values.
|
2011-10-28 02:04:53 +00:00
|
|
|
* 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.
|
2011-12-12 02:43:18 +00:00
|
|
|
* 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 <QtCore/QByteArray> header.
|
2011-12-19 05:22:51 +00:00
|
|
|
* 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.
|
2011-10-28 02:04:53 +00:00
|
|
|
* 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.
|
2012-09-20 14:36:51 +00:00
|
|
|
* The qCompare() function template was both overloaded and specialised, which
|
|
|
|
|
made it almost impossible to specialise the correct primary template and
|
|
|
|
|
could lead to indecipherable error messages or surprising overload resolution
|
|
|
|
|
(such as going via qCompare(QFlags<void*>,int) to satisfy a request for
|
|
|
|
|
qCompare<void*>()). Now, specialisation has been replaced by overloading.
|
|
|
|
|
As a consquence, code such as qCompare<QString>(l, r) will no longer use the
|
|
|
|
|
QString-specific implementation and may fail to compile. We recommend you
|
|
|
|
|
replace specialisations with overloading, too. Also, don't pass explicit
|
|
|
|
|
template arguments to qCompare (e.g. qCompare<QString>(l, r)), but let
|
|
|
|
|
overload resolution pick the correct one, and cast arguments in case of
|
|
|
|
|
ambiguous overloads (e.g. qCompare(QString(l), r)). The resulting code will
|
|
|
|
|
continue to work against older QtTestlib versions.

2011-11-14 11:33:55 +00:00
|
|
|
- The QSsl::TlsV1 enum value was renamed to QSsl::TlsV1_0 .
|
|
|
|
|
|
2011-11-22 13:33:15 +00:00
|
|
|
- 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()
|
2012-02-20 10:19:10 +00:00
|
|
|
* parent() and child() was added in order to do hierarchical navigation.
|
|
|
|
|
* relations() was added as a replacement to relationTo()
|
|
|
|
|
* As a consequence of the above two points, navigate() was removed.
|
2011-11-22 13:33:15 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2011-11-30 13:58:53 +00:00
|
|
|
- QSound has been moved from QtGui to QtMultimedia
|
|
|
|
|
|
2011-08-11 14:23:10 +00:00
|
|
|
- QTabletEvent::QTabletEvent does not take a hiResGlobalPos argument anymore,
|
|
|
|
|
as all coordinates are floating point based now.
|
|
|
|
|
|
2011-11-27 15:42:23 +00:00
|
|
|
- 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
|
2012-01-13 15:21:40 +00:00
|
|
|
TouchPointPrimary. QTouchEvent::TouchPoint::isPrimary() has
|
|
|
|
|
been removed.
|
2011-11-27 15:42:23 +00:00
|
|
|
|
|
|
|
|
* QWidget *widget() has been removed and is replaced by QObject
|
|
|
|
|
*target() in order to avoid QWidget dependencies.
|
|
|
|
|
|
2012-02-10 14:40:06 +00:00
|
|
|
* QEvent::TouchCancel has been introduced. On systems where it makes
|
|
|
|
|
sense this event type can be used to differentiate between a
|
|
|
|
|
regular TouchEnd and abrupt touch sequence cancellations caused by
|
|
|
|
|
the compositor, for example when a system gesture gets recognized.
|
|

|
- QMetaType
|
|
|
|
|
|
2012-02-01 11:58:31 +00:00
|
|
|
* Q_DECLARE_METATYPE(Foo*) now requires that Foo is fully defined. In
|
|
|
|
|
cases where a forward declared type should be used as a metatype,
|
|
|
|
|
Q_DECLARE_OPAQUE_POINTER(Foo*) can be used to allow that.
|
2012-05-24 12:35:45 +00:00
|
|
|
* Similarly, Q_DECLARE_METATYPE(QSharedPointer<Foo>), and
|
|
|
|
|
Q_DECLARE_METATYPE(QWeakPointer<Foo>) require Foo to be fully defined. Again
|
|
|
|
|
though, Q_DECLARE_OPAQUE_POINTER(Foo*) can be used to allow that.

|
|
|
- QItemEditorFactory
|
|
|
|
|
|
|
|
|
|
* The signature of the createEditor and valuePropertyName methods
|
|
|
|
|
have been changed to take arguments of type int instead of QVariant::Type.
|
|
|
|
|
|
2012-02-24 15:32:53 +00:00
|
|
|
- QModelIndex/QAbstractItemModel
|
|
|
|
|
|
|
|
|
|
* The integer value that can be stored in a QModelIndex is now of type
|
|
|
|
|
quintptr to match the size of the internal storage location.
|
|
|
|
|
* The createIndex() method now only provides the void* and quintptr
|
|
|
|
|
overloads, making calls with a literal 0 (createIndex(row, col, 0))
|
|
|
|
|
ambiguous. Either cast (quintptr(0)) or omit the third argument
|
|
|
|
|
(to get the void* overload).
|
|
|
|
|
|
2011-11-27 15:42:23 +00:00
|
|
|
- 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().
|
|
|
|
|
|
2011-12-10 14:30:18 +00:00
|
|
|
- The previously exported function qt_translateRawTouchEvent() has been removed.
|
|
|
|
|
Use QWindowSystemInterface::handleTouchEvent() instead.
|
|
|
|
|
|
2011-12-21 10:33:33 +00:00
|
|
|
- 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<int, int>. 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).

2012-01-02 15:47:59 +00:00
|
|
|
- QUuid
|
|
|
|
|
|
|
|
|
|
* Removed implicit conversion operator QUuid::operator QString(), instead
|
|
|
|
|
QUuid::toString() function should be used.
|
|
|
|
|
|
2011-12-22 19:42:49 +00:00
|
|
|
- The QHttp, QHttpHeader, QHttpResponseHeader and QHttpRequestHeader classes have
|
|
|
|
|
been removed, QNetworkAccessManager should be used instead.
|
|
|
|
|
|
2012-05-24 08:36:01 +00:00
|
|
|
- The QFtp and QUrlInfo classes are no longer exported, QNetworkAccessManager should be used
|
|
|
|
|
instead. These classes are available in a separate module, qtftp.
|
2012-01-11 12:48:08 +00:00
|
|
|
|
2012-01-05 17:24:53 +00:00
|
|
|
- QProcess
|
|
|
|
|
|
|
|
|
|
* On Windows, QProcess::ForwardedChannels will not forward the output of GUI
|
|
|
|
|
applications anymore, if they do not create a console.
|
2011-12-22 19:42:49 +00:00
|
|
|
|
2011-12-29 14:47:21 +00:00
|
|
|
- QAbstractSocket's connectToHost() and disconnectFromHost() are now virtual and
|
|
|
|
|
connectToHostImplementation() and disconnectFromHostImplementation() don't exist.
|
|
|
|
|
|
2012-01-11 15:06:14 +00:00
|
|
|
- QTcpServer::incomingConnection() now takes a qintptr instead of an int.
|
|
|
|
|
|
2012-01-17 13:57:55 +00:00
|
|
|
- QNetworkConfiguration::bearerName() removed, and bearerTypeName() should be used.
|
|
|
|
|
|
2012-01-19 09:29:41 +00:00
|
|
|
- QDir::convertSeparators() (deprecated since Qt 4.2) has been removed. Use
|
|
|
|
|
QDir::toNativeSeparators() instead.
|
2011-11-15 08:34:38 +00:00
|
|
|
|
2012-01-25 12:58:17 +00:00
|
|
|
- QIconEngineV2 was merged into QIconEngine
|
|
|
|
|
You might need to adjust your code if it used a QIconEngine.
|
|
|
|
|
|
2012-01-12 09:43:29 +00:00
|
|
|
- QTextCodecPlugin has been removed since it is no longer used. All text codecs
|
|
|
|
|
are now built into QtCore.
|
2012-01-19 09:29:41 +00:00
|
|
|
|
2012-01-30 13:09:13 +00:00
|
|
|
- QDir::NoDotAndDotDot is QDir::NoDot|QDir::NoDotDot therefore there is no need
|
|
|
|
|
to use or check both.
|
|
|
|
|
|
2012-02-17 19:09:17 +00:00
|
|
|
- QFSFileEngine, QAbstractFileEngine, QAbstractFileEngineIterator and
|
|
|
|
|
QAbstractFileEngineHandler were removed from public API and are no longer
|
|
|
|
|
exported. They may temporarily live as private implementation details, but
|
|
|
|
|
they may be altogether dropped or otherwise changed at will in the future.
|
|
|
|
|
|
2012-01-27 19:04:42 +00:00
|
|
|
- QLocale
|
|
|
|
|
* toShort(), toUShort(), toInt(), toUInt(), toLongLong() and toULongLong() no
|
|
|
|
|
longer take a parameter for base, they will only perform localised base 10
|
|
|
|
|
conversions. For converting other bases use the QString methods instead.
|
|
|
|
|
|
2012-01-27 20:21:21 +00:00
|
|
|
- QSystemLocale has been removed from the public API.
|
|
|
|
|
|
2012-04-02 20:02:31 +00:00
|
|
|
- QSqlQueryModel::indexInQuery() is now virtual. See note below under QtSql.
|
2012-02-09 13:53:35 +00:00
|
|
|
|
2012-03-22 20:27:26 +00:00
|
|
|
- QSqlDriver::subscribeToNotification, unsubscribeFromNotification,
|
|
|
|
|
subscribedToNotifications, isIdentifierEscaped, and stripDelimiters
|
|
|
|
|
are now virtual. See note below under QtSql.
|
|
|
|
|
|
2012-02-20 08:43:02 +00:00
|
|
|
- qMacVersion() has been removed. Use QSysInfo::macVersion() or
|
|
|
|
|
QSysInfo::MacintoshVersion instead.
|
|
|
|
|
|
2012-04-11 12:22:26 +00:00
|
|
|
- QColorDialog::customColor() now returns a QColor value instead of QRgb.
|
|
|
|
|
QColorDialog::setCustomColor() and QColorDialog::setStandardColor() now
|
|
|
|
|
take a QColor value for their second parameter instead of QRgb.
|
|
|
|
|
|
2012-05-20 19:38:21 +00:00
|
|
|
- QPageSetupDialog has had the PageSetupDialogOption enum and the api to
|
|
|
|
|
set and get the enum removed as none of the Options are used any more.
|
|
|
|
|
|
2012-05-20 21:38:28 +00:00
|
|
|
- QAbstractPageSetupDialog has been removed.
|
|
|
|
|
|
2012-10-18 16:33:03 +00:00
|
|
|
- QThread::terminated() has been removed, since its emission cannot be guaranteed.
|
|
|
|
|
|
2012-07-29 16:41:08 +00:00
|
|
|
- QPrintEngine - Removed the PPK_SuppressSystemPrintStatus key as no longer used.
|
|
|
|
|
|
2012-11-22 13:29:07 +00:00
|
|
|
- QCoreApplication::Type and QApplication::type() have been removed. These
|
|
|
|
|
Qt3 legacy application types did not match the application types
|
|
|
|
|
available in Qt5. Use for example qobject_cast instead to dynamically
|
|
|
|
|
find out the exact application type.
|
|
|
|
|
|
2012-11-30 21:24:08 +00:00
|
|
|
- The following QStyle implementations have been made internal:
|
|
|
|
|
* QFusionStyle
|
|
|
|
|
* QGtkStyle
|
|
|
|
|
* QMacStyle
|
|
|
|
|
* QWindowsCEStyle
|
|
|
|
|
* QWindowsMobileStyle
|
|
|
|
|
* QWindowsStyle
|
|
|
|
|
* QWindowsVistaStyle
|
|
|
|
|
* QWindowsXPStyle
|
|
|
|
|
Instead of creating instances or inheriting these classes directly, use:
|
|
|
|
|
* QStyleFactory for creating instances of specific styles
|
|
|
|
|
* QProxyStyle for customizing existing style implementations
|
|
|
|
|
* QCommonStyle as a base for implementing full custom styles.

General Improvements
|
|
|
|
|
--------------------
|
|
|
|
|
|
2011-10-28 02:04:53 +00:00
|
|
|
- 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.
|
2011-06-27 14:05:22 +00:00
|
|
|
|
2012-05-29 05:10:09 +00:00
|
|
|
- Qt is compiled with C++11 support enabled by default, provided the compiler
|
|
|
|
|
supports C++11. Qmake based projects can enable C++11 support explicitly
|
|
|
|
|
using 'CONFIG+=c++11' in their .pro files. To enable it conditionally, use
|
|
|
|
|
'contains(QT_CONFIG,c++11):CONFIG+=c++11'. This will enable C++11 support
|
|
|
|
|
only if Qt was built with C++11 support.
|
|
|
|
|
|
2012-09-27 22:57:39 +00:00
|
|
|
- The Unicode Data and Algorithms has been updated to match the
|
|
|
|
|
Unicode Standard of version 6.2. For more information see http://www.unicode.org/
|
|
|
|
|
|
2012-11-21 13:53:33 +00:00
|
|
|
- The QLocale data has been updated to CLDR 22.1.
|
|
|
|
|
For more information see http://cldr.unicode.org/

|
----------------------
|
|
|
|
|
|
2012-04-30 12:24:34 +00:00
|
|
|
- SQLITE_ENABLE_FTS3,SQLITE_ENABLE_FTS3_PARENTHESIS and SQLITE_ENABLE_RTREE
|
|
|
|
|
flags are now enabled by default on all platforms, for the sqlite3 copy under
|
|
|
|
|
the 3rdparty directory.

------
|
2012-09-27 22:57:39 +00:00
|
|
|
* [QTBUG-12144], [QTBUG-18360] The QChar methods are now able to handle the full range
|
|
|
|
|
of Unicode codepoints defined by the Unicode Standard of version 6.2.
|
|
|
|
|
QChar::isPrint() will no longer return a false positives for
|
|
|
|
|
the Unicode format characters, surrogates, and private use characters.
|
|
|
|
|
|
|
|
|
|
* Drop a bogus QChar::NoCategory enum value; the proper QChar::Other_NotAssigned
|
2011-07-08 14:24:57 +00:00
|
|
|
value is returned for an unassigned codepoints now.
|
2011-06-27 14:05:22 +00:00
|
|
|
|
2011-11-24 22:21:36 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-08-22 16:01:32 +00:00
|
|
|
* The QAbstractItemModel::sibling method was made virtual, allowing implementations
|
|
|
|
|
to optimize based on internal data.
|
|
|
|
|
|
2011-12-20 11:56:01 +00:00
|
|
|
* The default value of the property QSortFilterProxyModel::dynamicSortFilter was
|
|
|
|
|
changed from false to true.
|
|
|
|
|
|
2011-12-15 15:31:21 +00:00
|
|
|
* The signature of the virtual QAbstractItemView::dataChanged method has changed to
|
|
|
|
|
include the roles which have changed. The signature is consistent with the dataChanged
|
|
|
|
|
signal in the model.
|
|
|
|
|
|
2011-12-27 21:30:05 +00:00
|
|
|
* 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.
|
|
|
|
|
|
2012-01-23 12:02:36 +00:00
|
|
|
* QString::mid, QString::midRef and QByteArray::mid, if the position passed
|
|
|
|
|
is equal to the length (that is, right after the last character/byte),
|
|
|
|
|
now return an empty QString, QStringRef or QByteArray respectively.
|
|
|
|
|
in Qt 4 they returned a null QString or a null QStringRef.
|
|
|
|
|
|
2012-01-22 21:23:50 +00:00
|
|
|
* QString methods toLongLong(), toULongLong(), toLong(), toULong(), toInt(),
|
|
|
|
|
toUInt(), toShort(), toUShort(), toDouble(), and toFloat() no longer use the
|
|
|
|
|
default or system locale, they will always use the C locale. This is to
|
|
|
|
|
guarantee consistent default conversion of strings. For locale-aware conversions
|
|
|
|
|
use the equivalent QLocale methods.
|
|
|
|
|
|
2012-01-16 20:20:39 +00:00
|
|
|
* QDate, QTime, and QDateTime have undergone important behavioural changes:
|
2012-01-09 20:50:00 +00:00
|
|
|
* QDate only implements the Gregorian calendar, the switch to the Julian
|
|
|
|
|
calendar before 1582 has been removed. This means all QDate methods will
|
|
|
|
|
return different results for dates prior to 15 October 1582, and there is
|
|
|
|
|
no longer a gap between 4 October 1582 and 15 October 1582.
|
2012-01-16 20:20:39 +00:00
|
|
|
* QDate::setYMD() is deprecated, use QDate::setDate() instead
|
2011-07-17 18:30:12 +00:00
|
|
|
* Most methods now apply strict validity checks and will return appropriate
|
|
|
|
|
and consistent values when invalid. For example, QDate::year() will return
|
|
|
|
|
0 and QDate::shortMonthName() will return QString().
|
|
|
|
|
* Adding days to a null QDate or seconds to a null QTime will no longer return
|
|
|
|
|
a valid QDate/QTime.
|
2011-08-25 06:54:16 +00:00
|
|
|
* QDate stores the Julian Day as a qint64 extending date support across a
|
|
|
|
|
more interesting range, see the class documentation for details.
|
|
|
|
|
* Conversion to YMD form dates is only accurate between to 4800 BCE to
|
|
|
|
|
1.4 million CE
|
|
|
|
|
* The QDate::addDays() and QDateTime::addDays() methods now take a qint64
|
|
|
|
|
* The QDate::daysTo() and QDateTime::daysTo() methods now return a qint64
|
2012-01-16 20:20:39 +00:00
|
|
|
|
2012-01-30 12:23:22 +00:00
|
|
|
* QTextCodec::codecForCStrings() and QTextCodec::setCodecForCStrings() have both
|
|
|
|
|
been removed. This was removed due to issues with breaking other code from
|
|
|
|
|
libraries, creating uncertainty/bugs in using QString easily, and (to a lesser
|
|
|
|
|
extent) performance issues.
|
2012-01-16 20:20:39 +00:00
|
|
|
|
2012-05-16 21:09:56 +00:00
|
|
|
* QTextCodec::codecForTr() and QTextCodec::setCodecForTr() have been removed.
|
|
|
|
|
QObject::trUtf8 and QCoreApplication::Encoding enum are now obsolete. Qt assumes
|
|
|
|
|
that the source code is encoded in UTF-8.
|
2012-01-31 22:33:30 +00:00
|
|
|
|
2012-05-14 13:43:57 +00:00
|
|
|
* QFile::setEncodingFunction and QFile::setDecodingFunction are obsolete and do
|
|
|
|
|
nothing in Qt 5. The QFile::encodeName and QFile::decodeName functions are now
|
|
|
|
|
hardcoded to operate on QString::fromLocal8Bit and QString::toLocal8Bit
|
|
|
|
|
only. Therefore, it's still possible to obtain the old behaviour by calling
|
|
|
|
|
QTextCodec::setCodecForLocale. However, that is not recommended: new code
|
|
|
|
|
should not make assumptions about the filesystem encoding and older code should
|
|
|
|
|
have those assumptions removed.
|
|
|
|
|
|
2012-01-23 22:34:09 +00:00
|
|
|
* QIntValidator and QDoubleValidator no longer fall back to using the C locale if
|
|
|
|
|
the requested locale fails to validate the input.
|
|
|
|
|
|
2012-01-23 22:47:59 +00:00
|
|
|
* A new set of classes for doing pattern matching with Perl-compatible regular
|
|
|
|
|
expressions has been added: QRegularExpression, QRegularExpressionMatch and
|
|
|
|
|
QRegularExpressionMatchIterator. They aim to replace QRegExp with a more
|
|
|
|
|
powerful and flexible regular expression engine.
|
|
|
|
|
|
2012-02-14 10:17:36 +00:00
|
|
|
* QEvent::AccessibilityPrepare, AccessibilityHelp and AccessibilityDescription removed:
|
|
|
|
|
* The enum values simply didn't make sense in the first place and should simply be dropped.
|
|
|
|
|
|
2012-06-23 19:48:53 +00:00
|
|
|

2012-07-20 18:52:44 +00:00

QApplication::x11EventFilter/macEventFilter/qwsEventFilter/winEventFilter) have been replaced
|
2012-06-23 19:48:53 +00:00
|
|
|
with QCoreApplication::installNativeEventFilter and removeNativeEventFilter,
|
|
|
|
|
for an API much closer to QEvent filtering. Note that the native events that can be
|
|
|
|
|
filtered this way depend on which QPA backend is chosen, at runtime. On X11, XEvents are
|
|
|
|
|
not used anymore, and have been replaced with xcb_generic_event_t due to the switch to
|
|
|
|
|
XCB, which requires porting the application code to XCB as well.

* [QTBUG-23529] QHash is now more resilient to a family of denial of service
|

attacks exploiting algorithmic complexity, by supporting two-arguments overloads
|
|
|
|

* QStateMachine
|
|
|
|
|
- [QTBUG-15430] Added a QStateMachine constructor that takes a ChildMode parameter.
|
|
|
|
|
- [QTBUG-17975] Delayed event posting now works from secondary threads.
|
|
|
|
|
- [QTBUG-19789] Signal transitions now work correctly when the sender is in a different thread.
|
|
|
|
|
- [QTBUG-20362] Property assignments now work as expected with nested, parallel states.
|
|
|
|
|
- [QTBUG-22931] The root state can now be a parallel state group.
|
|
|
|
|
- [QTBUG-24307] The initial state is now entered before the started() signal is emitted.
|
|
|
|
|
- [QTBUG-25959] State entry and exit order is now SCXML spec-compliant.

2012-09-05 11:28:21 +00:00
|
|
|
* qDebug(), qWarning(), qCritical(), and qFatal() were changed to macros that track the origin
|
|
|
|
|
of the message in source code. Whether this and other meta-information is printed can be
|
|
|
|
|
configured (for the default message handler) by setting the new QT_MESSAGE_PATTERN environment
|
|
|
|
|
variable. qInstallMsgHandler() has been deprecated, and should be replaced with
|
|
|

qInstallMessageHandler().

|
|
|
|
- [QTBUG-6498] The word start and word end boundaries detection is now
|
|
|
|
|
unaware of surrounding white space characters.
|
|
|
|
|
- SoftHyphen enum value has been added to specify a line break opportunity
|
|
|
|
|
at a soft hyphen (SHY) character.
|
|
|
|
|
- MandatoryBreak enum value has been added to specify a mandatory (aka "hard") line breaks.
|
2012-10-28 19:13:02 +00:00
|
|
|
- Source-incompatible change: Since the behavior of boundaryReasons() method
|
|
|
|
|
has been changed a lot, StartWord/EndWord enum values were intentionally replaced
|
|
|
|
|
with StartOfItem/EndOfItem ones to force the affected code be revised.

|
|
|
|
QSurfaceFormat, and QOpenGLContext.
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
QOpenGLFunctions, etc.

* Behavioral change in QImage::fill() on an image with format Format_RGB888:

|
|
|
|
For consistency with RGB32 and other 32-bit formats, function now expects
|
|
|
|
|
image data in RGB layout as opposed to BGR layout.
|

|
|
|
2012-10-08 13:40:13 +00:00
|
|
|
* Behavioral change in QImage and QPixmap load()/loadFromData() on a non-null image:
|
|
|
|
|
If load() or loadFromData() fails to load the image (returns false) then
|
|
|
|
|
the existent image data will be invalidated, so that isNull() is guaranteed
|
|
|
|
|
to return true in this case.

* Behavioral change regarding QPainter fill rules when not using antialiased
|
|
|
|
|
painting: The fill rules have changed so that the aliased and antialiased
|
|
|
|
|
coordinate systems match. Earlier there used to be an offset of slightly less
|
|
|
|
|
than half a pixel when doing sub-pixel rendering, in order to be consistent
|
|
|
|
|
with the old X11 paint engine. The new behavior should be more predictable and
|
|
|
|
|
gives the same consistent rounding for images / pixmaps as for paths and
|
|
|
|
|
rectangle filling. It's possible to still get the old behavior by setting the
|
|
|
|
|
QPainter::Qt4CompatiblePainting render hint.
|
|
|
|
|
|
2012-10-15 15:06:34 +00:00
|
|
|
* Behavioral change regarding QPen: The default QPen constructors now create a
|
|
|
|
|
1-width non-cosmetic pen as opposed to a 0-width cosmetic pen. The old
|
|
|
|
|
behavior can be emulated by setting the QPainter::Qt4CompatiblePainting
|
|
|
|
|
render hint when painting.

|
* In Qt 4, QStyle::standardIconImplementation() and layoutSpacingImplementation()
|
|
|
|
|
were introduced instead of making the corresponding methods virtual due to binary
|
|
|
|
|
compatibility reasons. QStyle::standardIcon() and layoutSpacing() have been made
|
|
|
|
|
(pure) virtual in Qt 5.
|
|
|
|
|
|
Merge QStyleOption*V{2,3,4} classes together
In order to keep binary compatibility, Qt 4 introduced V{2,3,4}
classes for QStyleOption subclasses. They're simple, low level
containers for various members with public access (no accessors
required).
In Qt 5.0 we can break BC, so this patch moves the members
from the derived classes into the ``base'' ones.
The ``base'' ones get a version bump matching the highest
version available, and the V{2,3,4} classes become typedefs.
This change can cause problems in code that used QStyleOption
directly, especially QStyleOptionViewItem, because the old V4
fields get default initialization but the QStyle subclasses
detect that the option is a V4 option and expect all fields
to be properly initialized. The fix in such places is to
properly initialize all fields.

* In Qt 4, many QStyleOption subclasses were introduced in order to keep
|
|
|
|
|
binary compatibility -- QStyleOption was designed to be extended this way,
|
|
|
|
|
in fact it embeds a version number. In Qt 5 the various QStyleOption*V{2,3,4}
|
|
|
|
|
classes have been removed, and their members merged into the respective
|
|
|
|
|
base classes. Those classes were left as typedefs to keep existing code
|
|
|
|
|
working. Still, some minor adjustements could be necessary, especially in code
|
|
|
|
|
that uses QStyleOption directly and does not initialize all the members using
|
|
|
|
|
the proper Qt API: due to the version bump, QStyle will try to use the additional
|
|
|
|
|
QStyleOption members, which are left default-initialized.

|
|
|
|
|
before Qt 4.7.0, and are re-added for 5.0. This means that the userProperty for
|
|
|
|

* QGLPixelBuffer is now deprecated and implemented in terms of a hidden
|
|

QGLWidget and a QOpenGLFramebufferObject. It is recommended that applications
|

|
|
using QGLPixelBuffer for offscreen rendering to a texture switch to using
|
|
|
|

QOpenGLFramebufferObject directly instead, for improved performance.

2012-10-16 12:58:47 +00:00
|
|

|
with QSurfaceFormat. Applications that want to use a different version should
|
|
|
|

which were deprecated in Qt 4 have been removed.

both QGLWidget::renderText() functions.

* In order to ensure support on more platforms, stricter requirements have been
|
|
|
|
|
introduced for doing threaded OpenGL. First, you must call makeCurrent() at
|
|
|
|
|
least once per swapBuffers() call, so that the platform has a chance to
|
|
|
|
|
synchronize resizes to the OpenGL surface. Second, before doing makeCurrent()
|
|
|
|
|
or swapBuffers() in a separate thread, you must call
|
|
|
|
|
QGLContext::moveToThread(QThread *) to explicitly let Qt know in which thread
|
|
|
|
|
a QGLContext is currently being used. You also need to make sure that the
|
|
|
|
|
context is not current in the current thread before moving it to a different
|
|
|
|
|
thread.

QSqlTableModel::setData()/setRecord(): fix incorrect row
For OnFieldChange and OnRowChange, before submitting new changes,
setData() and setRecord() attempt to submit pending changes and
revert them upon failure. However, they fail to consider that
reverting pending insertions removes rows from the model. As a
result, the new change can be applied to a row higher than intended.
One possible solution would be to adjust the targetted index for the
removed rows, so that the intended row is affected by the new change.
But this still causes the strange editing experience as rows jump
up just as they are being edited.
It does not seem right in the first place for the model to initiate
reverting changes. It should be up to the application to decide what
to do when data cannot be committed. In particular, setData() and
setRecord() should not have the side effect of reverting already
pending changes.
The chosen solution is simply to refuse new changes that don't make
sense for the edit strategy. For OnFieldChange, flag() will
indicate read-only when editing is blocked by a pending change.
Since setData() and setRecord() submit data immediately for
OnFieldChange, it no longer makes sense to resubmit changes
automatically before a new change.
For OnRowChange, setData() keeps the behavior of automatically
submitting a pending row before starting on a new row. This is
historical behavior and is probably motivated by the fact that
QTableView does not automatically call submit() when editing leaves a
row. The obvious shortcoming of this is that the last row to be edited
will not be submitted automatically. It also prevents us from flagging
rows other than the pending row as read-only.
For OnRowChange, setRecord(), being row-oriented by nature, should
submit the change immediately rather than waiting for the next call
to setRecord(). This makes setRecord() consistent with insertRecord().

|
|
|
|
used on Mac OS X now.
|
|
|
|
|
* The following options have been added: (-no)-force-asserts, (-no)-strip, (-no)-gui &
|
|
|
|
|
(-no)-widgets, -device & -device-option, -archdatadir, -libexecdir & -qmldir,
|
|
|
|
|
and numerous changes relating to specific Qt features and dependencies.
|
|
|
|
|
* Configure will no longer call "qmake -recursive" by default, as the subsequent
|
|
|
|
|
build invokes qmake as needed. Use -fully-process to restore the old behavior.

* .qmake.conf files (.qmake.cache equivalent in source tree) are read now.
|
|
|
|
|
* Project-specific mkspecs/ and features/ directories are supported now.
|
|
|
|
|
QMAKEPATH and QMAKEFEATURES can be set in .qmake.{config,cache} to specifiy their
|
|
|
|
|
location, and qmake will find them in the project's top-level directory automatically.
|
|
|
|
|
* Mixing host and target subprojects is now supported. "default-host" makespec
|
|
|
|
|
was added; option(host_build) enables its use.
|
|
|
|
|
* QMAKE_MOC_OPTIONS variable is now available for passing additional parameters
|
|
|
|
|
to the moc.
|
|
|
|
|
* The CROSS_COMPILE variable and property can be used to parametrize the device
|
|
|
|
|
and mingw makespecs.
|
|
|
|
|
* QMAKE_RPATHLINKDIR (complementary to QMAKE_RPATHDIR) is now understood.
|
|
|
|
|
* The "aux" TEMPLATE was added. Does not work with vcproj and xcode output files.
|
|
|
|
|
* The properties QT_INSTALL_ARCHDATA, QT_INSTALL_LIBEXECS, QT_INSTALL_QML,
|
|
|
|
|
QMAKE_SPEC & QMAKE_XSPEC were added. QT_INSTALL_DEMOS is obsolete.
|
|
|
|
|
* The following functions have been added: $$sort_depends, $$resolve_depends,
|
|
|
|
|
$$enumerate_vars, $$reverse, $$val_escape, $$format_number, $$shadowed,
|
|
|
|
|

$$system_quote, $$shell_quote, cache, write_file, touch, mkpath & log.
|
|

defined can now query variables; $$cat and $$system support more splitting modes.
|
|
|
|
|
qtCompileTest (available from configure.prf) was added.
|
|
|
|
|
* Removed qttest_p4.prf. Use CONFIG+=testcase and other flags instead.
|
|
|
|
|
* QMAKE_SUBSTITUTES can now copy files verbatim.
|
|
|
|
|
* MSVC desktop builds now use -Zc:wchar_t.
|
|
|
|
|
* The following variables were added: QMAKESPEC, _QMAKE_CONF_ & _QMAKE_SUPER_CACHE_.
|
|
|
|
|
* QDBUSXML2CPP_{INTERFACES,ADAPTORS}_{HEADER,SOURCE}_FLAGS are now understood,
|
|
|
|
|
and DBUS_{INTERFACES,ADAPTORS} support file groups with individual flags now.
|
|
|
|
|
* QT_PRIVATE and PKGCONFIG_PRIVATE (analogous to LIBS_PRIVATE resp. PKGCONFIG) are now understood.
|
|
|
|
|
* INSTALLS entries now support copying with subdirectory (e.g., entry.base = $$dirname(PWD)).
|
|
|
|
|
* Defining QTPLUGIN in dynamically linked projects does not hurt any more.
|
|
|
|
|
* CONFIG+=import_plugins will now cause plugin imports for QTPLUGIN being auto-generated.
|
|
|
|
|
* Debug info generation can now be enabled also for release builds (CONFIG+=force_debug_info).
|
|
|
|
|
* The following CONFIG flags have been deprecated in favor of QT module entries:
|
|
|
|
|
qtestlib, qdbus, help, designer, uitools, qaxserver & qaxcontainer (the leading 'q'
|
|
|
|
|
was stripped from the affected modules).
|
|
|
|
|
* The IN_PWD alias for PWD was deprecated.
|
|
|
|
|
* QMAKE_{DIST,}CLEAN support normalized path separators now.
|
|
|
|
|
* CONFIG+=depend_includepath is on by default now. DEPENDPATH is unnecessary in most projects.
|
|
|
|
|
* Makespecs should be adjusted in the following ways:
|
|
|
|
|
* The QMAKE_INCDIR_QT, QMAKE_LIBDIR_QT, QMAKE_MOC, QMAKE_UIC, QMAKE_IDC, TEMPLATE & QT
|
|
|
|
|
variables should not be defined any more. Furthermore, QMAKE_LIBS_X11SM is obsolete.
|
|
|
|
|
* The qt, warn_on, release, & link_prl CONFIG flags should not be set any more.
|
|
|
|
|
* The QMAKE_PLATFORM & QMAKE_COMPILER variables should be defined now.
|
|
|
|
|
Several other variables should be defined by including files from mkspecs/common/.

- QPointer
|
|
|
|
|
|
2012-03-16 23:05:09 +00:00
|
|
|
* The implementation of QPointer has been changed to use QWeakPointer. The
|
|
|
|
|
old guard mechanism has been removed. This causes a slight change
|
|
|
|
|
in behavior when using QPointer:
|
2011-11-22 13:45:35 +00:00
|
|
|
|
|
|
|
|
* 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.
|
|
|

|
|
|
- QUrl
|
|
|
|
|
|
|
|
|
|
* QUrl has been changed to operate only on percent-encoded
|
|
|
|
|
forms. Fully-decoded forms, where the percent character stands for itself,
|
|
|
|
|
are no longer possible. For that reason, the getters and setters with
|
|
|
|
|
"encoded" in the name are deprecated, except for QUrl::toEncoded() and
|
|
|
|
|
QUrl::fromEncoded().
|
|
|
|
|
|
|
|
|
|
QUrl now operates in a mode where it decodes as much as it can of the
|
|
|
|
|
percent-encoding sequences. In addition, the setter methods possess a mode
|
|
|
|
|
in which a '%' character not part of a percent-encoding sequence will cause
|
|
|
|
|
the parser to correct the input. Therefore, most software will not require
|
|
|
|
|
changes to adapt, since the getter methods will continue returning the
|
|
|
|
|
components in their most-decoded form as they did before and the setter
|
|
|
|
|
methods will accept input as they did before..
|
|
|
|
|
|
|
|
|
|
The most notable difference is when dealing with
|
|
|
|
|
QUrl::toString(). Previously, this function would return percent characters
|
|
|
|
|
in the URL by themselves. Now, it will return "%25", like
|
|
|
|
|
QUrl::toEncoded().

- QLibraryInfo
|
|
|
|
|
|
|
|
|
|
* location() always returns paths with normalized separators now.
|
|
|
|
|
|
2012-01-30 11:21:43 +00:00
|
|
|
- QVariant
|
|
|
|
|
|
|
|
|
|
* Definition of QVariant::UserType changed. Currently it is the same as
|
|
|
|
|
QMetaType::User, which means that it points to the first registered custom
|
|
|
|
|
type, instead of a nonexistent type.
|
|
|
|
|
|
2012-02-13 15:26:35 +00:00
|
|
|
- QMetaType
|
|
|
|
|
|
|
|
|
|
* Interpretation of QMetaType::Void was changed. Before, in some cases
|
|
|
|
|
it was returned as an invalid type id, but sometimes it was used as a valid
|
|
|
|
|
type (C++ "void"). In Qt5, new QMetaType::UnknownType was introduced to
|
|
|
|
|
distinguish between these two. QMetaType::UnknownType is an invalid type id
|
|
|
|
|
signaling that a type is unknown to QMetaType, and QMetaType::Void
|
|
|
|
|
is a valid type id of C++ void type. The difference will be visible for
|
|
|
|
|
example in call to QMetaType::typeName(), this function will return null for
|
|
|
|
|
QMetaType::UnknownType and a pointer to "void" string for
|
|
|
|
|
QMetaType::Void.
|
|
|
|
|
Please, notice that QMetaType::UnknownType has value 0, which previously was
|
|
|
|
|
reserved for QMetaType::Void.

- QMessageBox
|
|
|
|
|
|
|
|
|
|
* The static function QMessageBox::question has changed the default argument
|
|
|
|
|
for buttons. Before the default was to have an Ok button. That is changed
|
|
|
|
|
to having a yes and a no button.

|
- qmake & configure
|
|
|
|
|
|
|
|
|
|
* The project file parser has been rewritten from scratch. Invalid syntax will be
|
|
|
|
|
rejected more aggressively, and interpretation may have changed in some corner cases.
|
|
|
|
|
* Projects which explicitly set an empty TARGET are considered broken now.
|
|
|
|
|
* The makespec and .qmake.cache do not see build pass specific variables any more.
|
|
|
|
|
* load()/include() with a target namespace and infile()/$$fromfile() now start with
|
|
|
|
|
an entirely pristine context.
|
|
|
|
|
* Configure's -sysroot and -hostprefix are now handled slightly differently.
|
|
|
|
|
The QT_INSTALL_... properties are now automatically prefixed with the sysroot;
|
|
|
|
|
the raw values are available as QT_INSTALL_.../raw and the sysroot as QT_SYSROOT.
|
|
|
|
|
The new QT_HOST_... properties can be used to refer to the Qt host tools.
|
|
|
|
|
-no-gcc-sysroot can be used for non-standard sysroot configurations.
|
|
|
|
|
* The QMAKE_MKSPECS property became unavailable at the command line. Query QT_HOST_DATA instead.
|
|
|
|
|
* The TEMPLATE_PREFIX variable is gone. Use contains(TEMPLATE, vc.*) instead.
|
|
|
|
|
* The "default" makespec symlink/directory is gone. Use qmake -query QMAKE_XSPEC instead.
|
|
|
|
|
* DEPENDPATH does not end up in VPATH any more. Some SOURCES may not be found any more.
|
|
|
|
|
* Several functions and built-in variables were modified to return normalized paths.
|
|
|
|
|
* The -(no-)exception flags in configure have been removed. Qt modules are now compiled
|
|
|
|
|
without exceptions by default, as they do not use them and can neither handle them
|
|
|
|
|
properly. Qt Core still has exceptions enabled to correctly throw bad_alloc exceptions
|
|
|
|
|
in our tool classes.
|
|
|
|
|
Whether code should be compiled with exception support enabled or disabled can be
|
|
|
|
|
controlled by a CONFIG += exceptions/exceptions_off setting in the .pro file.
|
|
|
|
|
* The -no/-stl configure options are gone. Qt always uses the STL now.
|
|
|
|
|
* The -prefix-install configure option is gone. Use -prefix, etc. instead.
|
|
|
|
|
* The -make option of the Windows configure was renamed to -make-tool.
|
|
|
|
|
-make now complements -no-make, like in the Unix version.
|
|
|
|
|
* The object_with_source CONFIG flag was removed. Use object_parallel_to_source instead.
|
|
|
|
|
* Support for universal binaries on Mac OS has been removed.
|
|
|
|
|
* The processor architecture handling changed significantly. This affects the -arch & -*-endian
|
|
|
|
|
configure options, the QT_ARCH qmake variable, and more.
|
|
|
|
|
* No "make_default" make targets will be generated any more. Use "make_first" instead.
|
|
|
|
|
* The "qmake" make targets are non-recursive now. Use "qmake_all" to recurse.
|
|
|
|
|
* load() with paths relative to the current project is not supported any more.
|
|
|
|
|
Use include() instead.
|
|
|
|
|
* Persistent qmake properties are not versioned any more. Also, the vendor changed to
|
|
|
|
|
"QtProject", so old settings are lost.
|
|
|
|
|
* Support for the Borland toolchain was removed. Numerous obsolete makespecs were culled.
|
|
|
|
|
* setcepaths.bat is gone. QMake-generated Makefiles are self-contained now.
|
|
|
|
|
* moc_dir, rcc_dir and some other tool variables are not defined in Qt's .pc files any more;
|
|
|
|
|
the generic host_bins is defined instead.
