Qt 5.2 introduces many new features and improvements as well as bugfixes
|
|
|
|
|
over the 5.1.x series. For more details, refer to the online documentation
|
|
|
|
|
included in this distribution. The documentation is also available online:

|
|
|
|
|
|
|
|
|
|
The Qt version 5.2 series is binary compatible with the 5.1.x series.
|
|
|
|
|
Applications compiled for 5.1 will continue to run with 5.2.

- QAbstractScrollArea now has a SizeAdjustPolicy. If it is set to AdjustToContents
|
|
|
|
|
it will make use of the new protected viewportSizeHint() (binary compatible since it
|
|
|
|
|
was reserved in Qt5). This function returns a suggested size based on contents.

|
|

|
columns than logicalindex zero.

- [QTBUG-4206] QTableView resizeToContents will now adjust to actual contents
|
|
|
|
|
and not just visible area. QHeaderView::setAutoResizePrecision() has been
|
|
|
|
|
introduced to control how precise the autoResize should be.

- [QTBUG-30250] QTime, QDateTime:
|
|
|
|
|
When calling QTime::toString(Qt::TextDate) and QTime::toString(Qt::ISODate),
|
|
|
|
|
milliseconds are now included in the returned string. This also applies to
|
|
|
|
|
QDateTime::toString(Qt::TextDate) and QDateTime::toString(ISODate).

- QtAlgorithms
|
|
|
|
|
With STL no longer being optional for building and using Qt, a number of parts
|
|
|
|
|
of QtAlgorithms no longer make sense, and have therefore been deprecated.
|
|
|
|
|
|
|
|
|
|
Replacements are available in the STL, and generally have much better
|
|
|
|
|
performance, but are not instantly source-compatible in all cases. For
|
|
|
|
|
instance, specialization of qLess or qSwap means that a direct port to
|
|
|
|
|
std::sort from qSort may not be possible, as std::sort does not use any of
|
|
|
|
|
them; a possible workaround is explicitly passing a qLess functor to
|
|
|
|
|
std::sort:
|
|
|
|
|
|
|
|
|
|
std::sort(container.begin(), container.end(), qLess<T>());
|
|
|
|
|
|
|
|
|
|
The functions in QtAlgorithms that have been deprecated, along with their
|
|
|
|
|
STL counterparts, are:
|
|
|
|
|
- qBinaryFind (std::binary_search / std::lower_bound)
|
|
|
|
|
- qCopy (std::copy)
|
|
|
|
|
- qCopyBackward (std::copy_backward)
|
|
|
|
|
- qEqual (std::equal)
|
|
|
|
|
- qFill (std::fill)
|
|
|
|
|
- qFind (std::find)
|
|
|
|
|
- qCount (std::count)
|
|
|
|
|
- qSort (std::sort)
|
|
|
|
|
- qStableSort (std::stable_sort)
|
|
|
|
|
- qLowerBound (std::lower_bound)
|
|
|
|
|
- qUpperBound (std::upper_bound)
|
|
|
|
|
- qLess (std::less)
|
|
|
|
|
- qGreater (std::greater)

- [QTBUG-28228] Session Management:
|
|
|
|
|
The new QPlatformSessionManager class brings back the session management
|
|
|
|
|
functionality. It allows the implementation of platform specific behavior
|
|
|
|
|
related to session management. For platform that don't support this
|
|
|
|
|
feature the default behavior has not changed.
|
|
|
|
|
Both X11 and Windows session management are supported.

- API was added to store and resume TLS session tickets.

|
|
|
|
|
2013-10-13 10:29:11 +00:00
|
|
|
- The minimum support openssl version has been increased to openssl 1.0. The
|
|
|
|
|
code to support older versions has not been removed, but is no longer
|
|
|
|
|
supported.
|
|
|
|
|
|
|
|
|
|
- An off-by-one error in NTLM proxy authentication has been fixed.
|
|
|
|
|
|
|
|
|
|
- Various improvements to reduce the memory used by qtnetwork have been made.
|
|
|
|
|
|
|
|
|
|
- Improved support for HTTP proxy authentication.
|
|
|
|
|
|
|
|
|
|
- Support for preconnecting to servers before making HTTP and HTTPS
|
|
|
|
|
connections. This allows for much reduced latency when the hosts to be
|
|
|
|
|
connected to are known.
