Jason McDonald 85a77cd5c8 Retire QTest::pixmapsAreEqual().
QTest::pixmapsAreEqual() was left in the Qt4 API for compatibility with
some old tests written for Qt3.  QCOMPARE() is the preferred way to
compare QPixmaps and provides superior diagnostic output when a
comparison fails.

This commit removes QTest::pixmapsAreEqual() from the testlib API and
replaces the last few remaining calls with QCOMPARE.

****************************************************************************
* Source incompatible changes *
****************************************************************************
- QSslCertificate::subjectInfo() and QSslCertificate::issuerInfo() now
return a QStringList instead of a QString
- 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.
- Unite clipping support has been removed from QPainter. The alternative is
to unite QRegion's and using the result on QPainter.
- QLibrary::resolve() now returns a function pointer instead of a void
pointer.
- QSslCertificate::alternateSubjectNames() is deprecated (but can be enabled
via QT_DISABLE_DEPRECATED_BEFORE), use
QSslCertificate::subjectAlternativeNames() instead.
- QLibraryInfo::buildKey() has been removed. Likewise, the QT_BUILD_KEY
preprocessor #define has also been removed. The build-key is obsolete
and is no longer necessary.
- QCoreApplication::translate() will no longer return the source text when
the translation is empty. Use lrelease -removeidentical for optimization.
- Qt::escape() is deprecated (but can be enabled via
QT_DISABLE_DEPRECATED_BEFORE), use QString::toHtmlEscaped() instead.
- QMetaType::construct() has been renamed to QMetaType::create().
- QTestLib:
* The QTRY_VERIFY and QTRY_COMPARE macros have been moved into QTestLib.
These macros formerly lived in tests/shared/util.h but are now provided
by including the <QtTest/QtTest> header.
* The QTEST_NOOP_MAIN macro has been removed from the API. If a test is
known at compile-time to be inapplicable for a particular build it should
be omitted via .pro file logic, or the test should call QSKIP in the
initTestCase() method to skip the entire test and report a meaningful
explanation in the test log.
* The DEPENDS_ON macro has been removed from the API. This macro did nothing
and misled some users to believe that they could make test functions depend
on each other or impose an execution order on test functions.
* The QTest::qt_snprintf function has been removed from the API. This was an
internal testlib function that was exposed in the public API due to its use
in a public macro. Any calls to this function should be replaced by a call
to qsnprintf(), which comes from the <QtCore/QByteArray> header.
* The QTest::pixmapsAreEqual() function has been removed from the API.
Comparison of QPixmap objects should be done using QCOMPARE, which provides
more informative output in the event of a failure.
* The QSKIP macro no longer has the "mode" parameter, which caused problems
for calculating test metrics, as the SkipAll mode hid information about
what test data was skipped. Calling QSKIP in a test function now behaves
like SkipSingle -- skipping a non-data-driven test function or skipping
only the current data row of a data-driven test function. Every skipped
data row is now reported in the test log.
- The QSsl::TlsV1 enum value was renamed to QSsl::TlsV1_0 .
- QAccessible:
* Internal QAccessible::State enum value HasInvokeExtension removed
- QAccessibleInterface:
* The "child" integer parameters have been removed. This moves the api
to be closer to IAccessible2.
This means several functions lose their integer parameter:
text(Text t, int child) -> text(Text t), rect(int child) -> rect()
setText(Text t, int child, const QString &text) -> setText(Text t, const QString &text)
role(int child) -> role(), state(int child) -> state()
relationTo(int child, const QAccessibleInterface *other, int otherChild) ->
relationTo(const QAccessibleInterface *other)
* Accessible-Action related functions have been removed. QAccessibleInterface
subclasses are expected to implement the QAccessibleActionInterface instead.
These functions have been removed:
QAccessibleInterface::userActionCount, QAccessibleInterface::actionText,
QAccessibleInterface::doAction
- QAccessibleEvent also loses the child parameter.
QAccessibleEvent(Type type, int child) -> QAccessibleEvent(Type type)
QAccessibleEvent::child() removed.
- QAccessibleActionInterface:
* Refactored to be based on action names. All functions have been changed from using
int parameters to strings.
- QSound has been moved from QtGui to QtMultimedia
- QTouchEvent:
* The DeviceType enum and deviceType() have been deprecated due to
the introduction of QTouchDevice.
* The signature of the constructor has changed. It now takes a
QTouchDevice pointer instead of just a DeviceType value.
* TouchPointState no longer includes TouchPointStateMask and
TouchPointPrimary. The primary flag is now stored together with
other touch point flags and is accessible through
TouchPoint::isPrimary() or TouchPoint::flags(). As a result the
internally used state mask is no longer necessary.
* QWidget *widget() has been removed and is replaced by QObject
*target() in order to avoid QWidget dependencies.
- QWindowSystemInterface:
* The signature of all handleTouchEvent() variants have changed,
taking a QTouchDevice* instead of just a DeviceType value.
Platform or generic plug-ins have to create and register at least
one QTouchDevice before sending the first touch event.
* The event type parameter is removed from handleTouchEvent().
- The previously exported function qt_translateRawTouchEvent() has been removed.
Use QWindowSystemInterface::handleTouchEvent() instead.

General Improvements
--------------------
- The directory structure of the qtbase unit-tests has been reworked to
more closely match the directory structure of the code under test.
Integration tests have been moved to tests/auto/integrationtests.
Third party components
----------------------
-
****************************************************************************
* Library *
****************************************************************************
QtCore
------
* drop a bogus QChar::NoCategory enum value; the proper QChar::Other_NotAssigned
value is returned for an unassigned codepoints now.
* layoutAboutToBeChanged is no longer emitted by QAbstractItemModel::beginMoveRows.
layoutChanged is no longer emitted by QAbstractItemModel::endMoveRows. Proxy models
should now also connect to (and disconnect from) the rowsAboutToBeMoved and
rowsMoved signals.
QtGui
-----
* Accessibility has been refactored. The hierachy of accessible objects is implemented via
proper parent/child functions instead of using navigate which has been deprecated for this purpose.
Table and cell interfaces have been added to qaccessible2.h
* Touch events and points have been extended to hold additional
information like capability flags, point-specific flags, velocity,
and raw positions.
QtWidgets
---------
* QWidget::setInputContext() is removed. Input contexts are now platform
specific.
QtNetwork
---------
* QHostAddress::isLoopback() API added. Returns true if the address is
one of the IP loopback addresses.
* QSslCertificate::serialNumber() now always returns the serial number in
hexadecimal format.
QtOpenGL
--------
QtScript
--------
QTestLib
--------
* [QTBUG-20615] Autotests can now log test output to multiple destinations
and log formats simultaneously.

* Important Behavior Changes *
****************************************************************************
- QPointer
* QPointer itself is now deprecated, and the implementation of QPointer
has been changed to use QWeakPointer. The old guard mechanism has been
removed. This causes two slight changes in behavior when using
QPointer:
* When using QPointer on a QWidget (or a subclass of QWidget), previously
the QPointer would be cleared by the QWidget destructor. Now, the QPointer
is cleared by the QObject destructor (since this is when QWeakPointers are
cleared). Any QPointers tracking a widget will NOT be cleared before the
QWidget destructor destroys the children for the widget being tracked.
* When constructing a QSharedPointer to take ownership of an object after a
QPointer is already tracking the object. Previously, the shared pointer
construction would not be affected by the QPointer, but now that QPointer
is implemented using QWeakPoiner, constructing the QSharedPointer will
cause an abort().
