11 * Source incompatible changes *
12 ****************************************************************************
15 - QSslCertificate::subjectInfo() and QSslCertificate::issuerInfo() now
16 return a QStringList instead of a QString
18 - QSslCertificate::isValid() has been deprecated. Originally it only checked
19 the certificate dates, but later checking for blacklisting was added. Now
20 there's a more specific QSslCertificate::isBlacklisted() method.
22 - Unite clipping support has been removed from QPainter. The alternative is
23 to unite QRegion's and using the result on QPainter.
25 - QLibrary::resolve() now returns a function pointer instead of a void
28 - QSslCertificate::alternateSubjectNames() is deprecated (but can be enabled
29 via QT_DISABLE_DEPRECATED_BEFORE), use
30 QSslCertificate::subjectAlternativeNames() instead.
32 - QLibraryInfo::buildKey() has been removed. Likewise, the QT_BUILD_KEY
33 preprocessor #define has also been removed. The build-key is obsolete
34 and is no longer necessary.
36 - QCoreApplication::translate() will no longer return the source text when
37 the translation is empty. Use lrelease -removeidentical for optimization.
39 - Qt::escape() is deprecated (but can be enabled via
40 QT_DISABLE_DEPRECATED_BEFORE), use QString::toHtmlEscaped() instead.
42 - QMetaType::construct() has been renamed to QMetaType::create().
45 * The QTRY_VERIFY and QTRY_COMPARE macros have been moved into QTestLib.
46 These macros formerly lived in tests/shared/util.h but are now provided
47 by including the <QtTest/QtTest> header.
48 * The QTEST_NOOP_MAIN macro has been removed from the API. If a test is
49 known at compile-time to be inapplicable for a particular build it should
50 be omitted via .pro file logic, or the test should call QSKIP in the
51 initTestCase() method to skip the entire test and report a meaningful
52 explanation in the test log.
53 * The DEPENDS_ON macro has been removed from the API. This macro did nothing
54 and misled some users to believe that they could make test functions depend
55 on each other or impose an execution order on test functions.
56 * The QSKIP macro no longer has the "mode" parameter, which caused problems
57 for calculating test metrics, as the SkipAll mode hid information about
58 what test data was skipped. Calling QSKIP in a test function now behaves
59 like SkipSingle -- skipping a non-data-driven test function or skipping
60 only the current data row of a data-driven test function. Every skipped
61 data row is now reported in the test log.
63 - The QSsl::TlsV1 enum value was renamed to QSsl::TlsV1_0 .
66 * Internal QAccessible::State enum value HasInvokeExtension removed
67 - QAccessibleInterface:
68 * The "child" integer parameters have been removed. This moves the api
69 to be closer to IAccessible2.
70 This means several functions lose their integer parameter:
71 text(Text t, int child) -> text(Text t), rect(int child) -> rect()
72 setText(Text t, int child, const QString &text) -> setText(Text t, const QString &text)
73 role(int child) -> role(), state(int child) -> state()
74 relationTo(int child, const QAccessibleInterface *other, int otherChild) ->
75 relationTo(const QAccessibleInterface *other)
76 * Accessible-Action related functions have been removed. QAccessibleInterface
77 subclasses are expected to implement the QAccessibleActionInterface instead.
78 These functions have been removed:
79 QAccessibleInterface::userActionCount, QAccessibleInterface::actionText,
80 QAccessibleInterface::doAction
81 - QAccessibleEvent also loses the child parameter.
82 QAccessibleEvent(Type type, int child) -> QAccessibleEvent(Type type)
83 QAccessibleEvent::child() removed.
84 - QAccessibleActionInterface:
85 * Refactored to be based on action names. All functions have been changed from using
86 int parameters to strings.
88 - QSound has been moved from QtGui to QtMultimedia
90 ****************************************************************************
92 ****************************************************************************
97 - The directory structure of the qtbase unit-tests has been reworked to
98 more closely match the directory structure of the code under test.
99 Integration tests have been moved to tests/auto/integrationtests.
101 Third party components
102 ----------------------
107 ****************************************************************************
109 ****************************************************************************
113 * drop a bogus QChar::NoCategory enum value; the proper QChar::Other_NotAssigned
114 value is returned for an unassigned codepoints now.
118 * Accessibility has been refactored. The hierachy of accessible objects is implemented via
119 proper parent/child functions instead of using navigate which has been deprecated for this purpose.
120 Table and cell interfaces have been added to qaccessible2.h
125 * QWidget::setInputContext() is removed. Input contexts are now platform
130 * QHostAddress::isLoopback() API added. Returns true if the address is
131 one of the IP loopback addresses.
133 * QSslCertificate::serialNumber() now always returns the serial number in
146 * [QTBUG-20615] Autotests can now log test output to multiple destinations
147 and log formats simultaneously.
