|

Qt is now compiled with qreal typedef'ed to double on all platforms. qreal
|
||||
was a float on ARM chipsets before. This guarantees more consistent behavior
|
||||
between all platforms Qt supports, but is binary incompatible to Qt 5.1
|
||||
on ARM. The old behavior can be restored by passing -qreal float to
|
||||
configure.

- Qt is now compiled with qreal typedef'ed to double on all

|

incompatible to Qt 5.1 on ARM. The old behavior can be restored by
|
||||
passing -qreal float to configure.
|
||||
- The supported date range in QDateTime has been reduced to about +/- 292
|
||||
million years, the range supported by the number of msecs since the Unix
|
||||
epoch of 1 Jan 1970 as stored in a qint64, and as able to be used in the
|
||||
setMSecsSinceEpoch() and toMSecsSinceEpoch() methods.
|
||||
|
||||
- QUrl and QUrlQuery:
|
||||
* [QTBUG-31660] QUrl no longer considers all delimiter characters
|
||||
equivalent to their percent-encoded forms. Now, both classes always
|
||||
keep all delimiters exactly as they were in the original URL text.
|
||||
* [QTBUG-31660] QUrl no longer decodes %7B and %7D to "{" and "}" in the
|
||||
output of toString()
|
||||
* QUrl no longer supports QUrl::FullyDecoded mode in authority() and
|
||||
userInfo(), nor QUrl::DecodedMode in setAuthority() and setUserInfo().
|
||||
* [QTBUG-31945] QUrl no longer decodes %23 found in the fragment to "#"
|
||||
in the output of toString(QUrl::FullyEncoded) or toEncoded()
|
||||
* QUrl now defaults to decoded mode in the getters and setters for
|
||||
userName, password, host, topLevelDomain, path and fileName. This
|
||||
means a '%' in one of those fields is now returned (or set) as '%'
|
||||
rather than "%25". In the unlikely case where the former behavior was
|
||||
expected, pass PrettyDecoded to the getter and TolerantMode to the
|
||||
setter.
|
||||
* QUrl now normalizes the path given in setPath, removing ./ and ../ and
|
||||
duplicate slashes.

QtWidgets
|

---------
|
||||
|
||||
- QAbstractScrollArea now has a SizeAdjustPolicy. If it is set to AdjustToContents
|
||||
it will make use of the protected viewportSizeHint() virtual function. This
|
||||
function returns a suggested size based on contents. Note that although the
|
||||
viewportSizeHint() virtual function was reserved in 5.0, user code was not
|
||||
supposed to be overriding it (as the function was private and undocumented).
|
||||
Code that was overriding viewportSizeHint() needs to be recompiled against 5.2
|
||||
for this feature to work correctly.
|
||||
|
||||
- QTreeView now has setTreePosition to allow the treestructure to show data from other
|
||||
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.
|
||||
|
||||
- QFileDialog::setDefaultSuffix() removes leading dot characters.
|
||||
|
||||
- [QTBUG-34132] QFileDialog does not instantiate widgets if a native dialog
|
||||
will be used instead. Therefore some accessors which previously returned
|
||||
unused objects will now return null. As before, you can set the
|
||||
DontUseNativeDialog option to ensure that widgets will be created and used instead.
|
||||
|
||||
- QSizePolicy got a retainSizeWhenHidden attribute.
|
||||
|
||||
- [QTBUG-31602] QSpinBox size calculation will now be fixed when stylesheets are
|

used.

Qt::OffsetFromUTC, added new methods for offsetFromUTC(),

toTimeSpec(), and toOffsetFromUTC().
|

* Added convenience methods for fromMSecsSinceEpoch() and fromTime_t()
|

to take time spec to be used in returned datetime.
|

* Add method timeZoneAbbreviation() to return effective time zone
|

abbreviation.
|
||||
* The debug datastream is now an ISO-like format instead of Qt::TextDate
|
||||
* The Standard Time to Daylight Time transition for Qt::LocalTime is now
|

handled correctly. Any date set in the "missing" hour is now
|
||||
considered invalid. All date math results that fall into the missing
|

hour will be automatically adjusted to a valid time in the following

hour.
|

* Added new method isDaylightTime() to return if the datetime is in

|

define times in a specific time zone.

QStandardPaths::setTestModeEnabled.

the returned string. This also applies to
|

QDateTime::toString(Qt::TextDate) and
|
||||
QDateTime::toString(ISODate).
|
||||
* Added new methods fromMSecsSinceStartOfDay() to create a new QTime
|
||||
from an msecs value, and msecsSinceStartOfDay() to return the QTime as
|
||||
the number of msecs since the start of the day.
|
||||
|
||||
- QTimeZone:
|
||||
* Added new QTimeZone class to support time tone calculations using the
|
||||
host platform time zone database and the Olsen time zone ID's.
|
||||
|
||||
- QUrl:
|
||||
* [QTBUG-33229] QUrl now fully accepts non-character unicode points;

they are encoded as percent characters; they can also be pretty

decoded
|

|

Changes in Qt 5.1.0 (missing from released changelog dist/changes-5.1.0)
|
||||
- [QTBUG-28088] Remove dependency of DB driver headers on qsqlcachedresult_p.h.
|
||||
- Deprecate QSqlError setters.
|
||||
The constructor is sufficient, since it has a parameter for each member variable.
|
||||
- Rename the SQL driver header files to _p.h (make private)
|
||||
The drivers were never public API. They were exposed by mistake in
|
||||
public headers. What's more, they have #include'd a private header
|
||||
(qsqlcachedresult_p.h) since at least Qt 4.5.1. That means no one used
|
||||
those headers in Qt 4 (private headers weren't installed then) and
|
||||
it's unlikely anyone did in 5.0.
|
||||
- ODBC: Implemented lastInsertId() for some ODBC compatible databases.
|
||||
- PSQL: Make lastInsertID work for tables without OIDs.
|
||||
- [QTBUG-14904] SQLITE: Fix for Sql query aliases with dots
|
||||
- [QTBUG-2192] ODBC: fix loss of milliseconds when binding QDateTime
|
||||
- [QTBUG-30076] PSQL: escape backslashes only when server requires it
|
||||
IMPORTANT: Applications that implemented their own workarounds must be
|
||||
updated to avoid misbehavior and SQL injection vulnerabilities.
|
||||
- [QTBUG-10569] ODBC: fixed QODBCResult::exec() return value for DELETE
|
||||
operations when no rows are affected.
|
||||
- ODBC: Fixed loss of column metadata on SQL_NO_DATA.
|
||||
- QSqlTableModel: expose methods for getting primary values.
|
||||
- ODBC: Fixed possible cause of spurious errors (commit af35ee291a1bbbc8)

only scroll 1 pixel when scrollMode is set to scrollPerPixel. That is

it will (when scrollMode is scrollPerPixel) do what is stated in the
