Qt 5.12.1 is a bug-fix release. It maintains both forward and backward
|
||||
compatibility (source and binary) with Qt 5.12.0.
|
||||
|
||||
For more details, refer to the online documentation included in this
|
||||
distribution. The documentation is also available online:
|
||||
|
||||
http://doc.qt.io/qt-5/index.html
|
||||
|
||||
The Qt version 5.12 series is binary compatible with the 5.11.x series.
|
||||
Applications compiled for 5.11 will continue to run with 5.12.
|
||||

* Important Behavior Changes *

****************************************************************************
|
||||
|
||||
- qmake / WinRT:
|
||||
* Cross-builds will now ignore pre-set values of %INCLUDE% and %LIB%
|
||||
when building target executables. If necessary, use configure's -I and
|
||||
-L switches when building Qt, and pass QMAKE_INCDIR and QMAKE_LIBDIR
|
||||
on qmake's command line when building own projects.

- Fixed the icons for the "file save" action that were inaccurate
|
||||
representations of a 3.5-inch floppy disk (the cut edge was on the wrong
|
||||
side). Now all floppy representations are physically accurate.

|
||||
- [QTBUG-71256] QString, QByteArray and QLocale's toDouble return an infinity
|
||||
on overflow (since 5.7), while setting ok to false; this was at odds with
|
||||
their documented behavior of returning 0 on failure. The documentation now
|
||||
reflects the actual behavior.
|
||||
- [QTBUG-71868] QString, QByteArray and QLocale's toFloat returned an
|
||||
infinity on double-overflow (since 5.7) but returned 0 on a finite double
|
||||
outside float's range, while setting ok to false; this was at odds with
|
||||
their documented behavior of returning 0 on any failure. They also
|
||||
succeeded, returning zero, on underflow of float's range, unless double
|
||||
underflowed, where they failed. Changed the handling of values outside
|
||||
float's range to match that of values outside double's range: fail,
|
||||
returning an infinity on overflow or zero on underflow. The documentation
|
||||
now reflects the revised behavior, which matches toDouble().
|
||||
|
||||
- QCborStreamReader:
|
||||
* [QTBUG-71426] Made setDevice() clear the last error.
|
||||
|
||||
- QCollator:
|
||||
* [QTBUG-58621] Added support for collation in the C locale, albeit this is
|
||||
only well-defined for ASCII. Collation sort keys remain unsupported on
|
||||
Darwin.
|
||||
|
||||
- QContiguousCache:
|
||||
* [QTBUG-52125] Fixed a memory leak.
|
||||
|
||||
- QObject:
|
||||
* [QTBUG-32340] Fixed a bug that caused isSignalConnected() to return
|
||||
true if the signal was connected and later disconnected.
|
||||
* [QTBUG-71550] Fixed a bug that caused isSignalConnected() not to
|
||||
report signals that were connected by the QML engine.
|
||||
|
||||
- QPluginLoader:
|
||||
* [QTBUG-71443] Fixed the parsing of ELF headers (Linux, FreeBSD, Solaris,
|
||||
etc.), which could cause certain valid plugins to not be deteced as
|
||||
valid.
|
||||
|
||||
- QRegularExpression:
|
||||
* [QTBUG-72539] The wildcardToRegularExpression method now returns a
|
||||
properly anchored pattern.
|
||||
|
||||
- QSettings:
|
||||
* [QTBUG-72007] Fixed QSettings parsing of blank spaces after comment lines
|
||||
in INI-style configuration files.
|
||||
|
||||
- QStringListModel:
|
||||
* setData will now emit the dataChanged() signal only if the string set
|
||||
is different from the one already contained in the model
|
||||
|
||||
- QSysInfo:
|
||||
* [QTBUG-72489] Now returns "Mojave" in prettyProductName() for macOS
|
||||
10.14.
|
||||
|
||||
- QUrl:
|
||||
* [QTBUG-71973] Changed the normalization done by
|
||||
QUrl::NormalizePathSegments) to match what web browsers do for non-local
|
||||
URLs.

- Text:
|
||||
* Fixed a bug where eliding text could change the height of its bounding
|
||||
rectangle for certain fonts.
|
||||
* Improved appearance of monochrome text on some platforms.
|
||||
* Fixed so ShowTabsAndSpaces will use the correct font.

- Reverted a Qt 5.12.0 behavior change in QToolTip that made plain tooltip
|
||||
text be wrapped automatically.
|
||||
- [QTBUG-72844] Fixed a regression related to accepting a Drag'n'Drop event.
|
||||
- [QTBUG-27110] Reverted a change that caused a regression related to
|
||||
styling a QListView using CSS.
|
||||
|
||||
- QWidgetLineControl/security:
|
||||
* Zero-out the string that contains a password entered into the
|
||||
QLineEdit
|
||||
* Preallocate a buffer for the string that contains the entered value
|
||||
when the QLineEdit serves as a password input field to minimize
|
||||
reallocations.

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

* Platform Specific Changes *
|

****************************************************************************
|
||||
|
||||
- Android:
|
||||
* QClipboard now supports HTML and URI data.
|
||||
|
||||
- Windows:
|
||||
* Reduced the number of font engines that are created when loading new
|
||||
fonts, fixing crashes in some special cases where a large number of
|
||||
fonts are created during a short period of time.
|
||||
|
||||
- X11:
|
||||
* [QTBUG-71296] Fixed a bug with open/close hand cursors not being shown
|
||||
correctly.
|
||||
* [QTBUG-46626][QTBUG-70756] Fixed a bug with dialogs hidden by other
|
||||

- moc now parses enum struct the same way as enum class therefore that

||||

||||
