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. + - 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. + - 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. -- QTreeView now has setTreePosition to allow the treestructure to show data from other - columns than logicalindex zero. + - 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. -- [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. +**************************************************************************** +* Library * +**************************************************************************** -- QFileDialog::setDefaultSuffix() removes leading dot characters. +QtCore +------ -- QSizePolicy got a retainSizeWhenHidden attribute. + - Added QCollator, a class to collate Unicode strings. + - Added QCommandLineParser, a class to parse command lines. + - Added QFileSelector, a class to select platform-specific file assets. + - Added QLoggingCategory and related functions for logging + - [QTBUG-23946] Fixed a bug that prevented Qt from being built in a + namespace on Mac OS X. + - Updated the locale database to CLDR 23.1 + - Added support for ARMv8 64-bit mode. -- [QTBUG-31602] QSpinBox size calculation will now be fixed when stylesheets are - used. + - Metatype system (QMetaType & QVariant): + * Qt now handles metatypes automatically for std::vector, std::list, + std::pair and std::map + * The metatype system now supports registering explicit conversion + functions via QMetaType::registerConverter + * The metatype system now supports iteration over a container type via + QSequentialIterable and QAssociativeIterable + * Registering the same type name twice will now print only a warning (as + opposed to aborting the execution of the program) -QtCore ------- -- [QTBUG-30250] QTime, QDateTime: - When calling QTime::toString(Qt::TextDate) and QTime::toString(Qt::ISODate), - milliseconds are now included in the returned string.

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) + +Changes in Qt 5.2.0 + - [QTBUG-29261] IBASE: Construct a valid QTime when creating timestamps for + iBase SQL driver. + - [QTBUG-33389] PSQL: Format QDateTime following ISO8601. + - Add QSQLITE_OPEN_URI option to QSQLITE driver + +QtWidgets +--------- + + - [QTBUG-30255] Fixed a bug where spans across empty cells in a grid + layout got broken. + - [QTBUG-32788] Properly handles Qt::WidgetWithChildrenShortcut + shortcuts in MDI subwindows now. + - [QTBUG-33078] QWidget::setWindowOpacity() now works when called + before QWidget::show(). + - [QTBUG-33247] Changed accessible trees and tables to always expose + hidden headers, instead of only exposing the visible headers. + - [QTBUG-34007] Fixed a crash in tablet support. + - Fixed a bug where the maximum size hint of a layout with spans was + wrong. + - Item delegates now cycle through all three states of tri-state + checkboxes, the same way QCheckBox itself does. + + - QAbstractItemView: + * [QTBUG-7232] In ItemViews scrollbars will now by default only + scroll 1 pixel when scrollMode is set to scrollPerPixel.

The user can now control that value. + + - QAbstractScrollArea: + * 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).

This improves the file + dialog performance under Windows for the case where there are + lots of folders. Went from taking 60 seconds to 2 seconds, on a + SDCard with 10k folders. + * Added setMimeTypeFilters() for mimetype-based filtering, as an + alternative to pattern matching. + * Fixed removing of directories containing hidden or system files. + * Added QUrl-based API for remote files. + * [QTBUG-13182] Improved performance on Windows by + + not resolving NTFS symlinks (15x speedup on pessimistic + workloads) and + + using extensions over calling GetFileAttributesEx() in certain + cases. + * [QTBUG-29403] Fixed potential crash in destructor of + ~QFileInfoGather in threaded applications. + * [QTBUG-34132] QFileDialog does no longer 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. + * [QTBUG-33039] Does no longer create widgets when using the + platform dialog. + + - QFontDialog: + * Now has finer-grained control over the types of fonts listed, + similar to what QFontComboBox already had. + + - QGraphicsView etc + * Fixed a crash in QGraphicsProxyWidget. + * [QTBUG-8061] Allow handling of mouseDoubleClickEvent in + QGraphicsItems. + * [QTBUG-19036] Make QGraphicsScene::items(QPointF) work using + Qt::{Contains,Intersets}ItemBoundingRect with items that contain + the point in the bounding rectangle, but not their (custom) + shape. + + - QHeaderView: + * [QTBUG-4346] A maximumSize for sections has been introduced. The + maximum section size is by default the largest possible section + size which in Qt 5.2 has been limited to 1048575 pixels. + + - QInputDialog: + * Added getMultiLineText static method. + + - QLineEdit: + * Keep placeholderText visible when focused, until text is added. + * Context-menu actions now have icons. + * Made it possible to add side widgets. + * Made it possible to add a clear button commonly used for item + view filtering as a side widget + + - QListView: + * [QTBUG-1180] Dragging an item outside the QListView in icon mode + no longer loses the icon. Also fixed a bug where under certain + conditions code overriding QAbstractItemView::viewOptions() would + not be called. + + - QMenuBar: + * [QTBUG-32807] Menus now close again on second click. + + - QMessageBox: + * May use native message boxes on some platforms now. + * [QTBUG-6731] It is now possible to select some or all text from a + QMessageBox and copy it to the clipboard. + + - QSizePolicy: + * Added a retainSizeWhenHidden attribute. + + - QSpinBox: + * Values can now be displayed in different bases + (cf. displayIntegerBase property) + * [QTBUG-31602] Size calculation will now be fixed when stylesheets + are used. + + - QSplitter: + * Now gets the default value of opaqueResize property from (new) + QStyle::SH_Splitter_OpaqueResize styleHint. + + - QSystemTrayIcon: + * [QTBUG-31762] Fixed position of system tray icon on Linux/X11 + (except Unity). + * [QTBUG-33461] Increased the maximum length of a system tray + tooltip on Windows to what it was in Qt 4. + + - QTableView: + * [QTBUG-4206] 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. + + - QTextEdit: + * Added placeholderText akin to QLineEdit. + * Context-menu actions now have icons. + + - QTreeView: + * QTreeView now has setTreePosition to allow the treestructure to + show data from other columns than logicalindex zero. + + - QWindowContainer: + * [QTBUG-32177] Sets active window correctly now. + + - QWizard: + * [QTBUG-29924] Gave all buttons an objectName(). + +**************************************************************************** +* Platform Specific Changes * +**************************************************************************** + + +Android +------- + + - Project structure and deployment has changed with the introduction of + androiddeployqt. Source and build files are no longer mixed, and the + build files for the APK package should not be touched. Customizing + the build files is possible. Read the documentation for androiddeployqt + for more information. + - Status bar visibility is now controlled by Qt, so the window state will + override settings in the AndroidManifest.xml. The default is still to + show the status bar (QWindow::showMaximized()). Use + QWindow::showFullScreen() to hide it. + - Implemented support for accessibility on Android. + +OS X +---- -- 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. + - Qt for OS X is now identified by the macro Q_OS_OSX. This complements the + existing Q_OS_DARWIN macro (which identifies the open source kernel and + could identify non-Apple products) and Q_OS_MAC, which is defined for + both OS X and iOS. The old macro Q_OS_MACX is now deprecated. + - Qt no longer complains about new versions of OS X that haven't been + released yet. This will allow Qt 5.2 and future versions to build on + future versions yet to be released. Note that those versions are not + supported until official announcement by the Qt Project. + - Added a number of functions to QtCore to convert to and from + CFString/NSString and QString, CFURL/NSURL and QUrl. -- An off-by-one error in NTLM proxy authentication has been fixed. +Windows +------- -- Various improvements to reduce the memory used by qtnetwork have been made. + - [QTBUG-33409][QTBUG-8764][QTBUG-10032] Fixed virtual key mapping on + Windows. + - QCoreApplication::arguments() changed the handling of single quotes, double quotes + and the backslash character, in order to match what argv[] contains. + In particular, single quotes are no longer removed from the argument string. + (QTBUG-15379, QTBUG-30628) -- Improved support for HTTP proxy authentication. +X11 +--- -- 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. + - [QTBUG-31762] Fix position of system tray icon (except Unity) + - [QTBUG-27349] Reintroduced command line argument for positioning + windows (-geometry) |
