For more details, see the online +documentation which is included in this distribution. The +documentation is also available at http://qt.nokia.com/doc/4.4 + +The Qt version 4.4 series is binary compatible with the 4.3.x series. +The Qt for Embedded Linux version 4.4 series is binary compatible with the +Qtopia Core 4.3.x series. Applications compiled for 4.3 will continue to +run with 4.4. + +Some of the changes listed in this file include issue tracking numbers +corresponding to tasks in the Task Tracker: + + http://qt.nokia.com/developer/task-tracker + +Each of these identifiers can be entered in the task tracker to obtain +more information about a particular change. + +**************************************************************************** +* General * +**************************************************************************** + +General Improvements +-------------------- + +- Legal + * This version introduces the GPL version 3 as an alternative + license for the Open Source Edition of Qt, in addition to the + existing licenses. + * Updated the GPL Exception to version 1.2, which grants additional + rights to developers using the LGPL version 3.0 and other licenses + for their software. + +- Configuration/Compilation + * [102113, 151125] Make it possible to use Qt headers with MSVC's + warning level 4. + * [129841] Make Qt compile with Intel C++ 9.0 and Intel C++ 10 compilers + on Windows. + * [168868] Add experimental support for the Blackfin processor. + * [188167] Fixed a bug in the solaris-cc mkspec that would cause + it to always use RPATH, even when configured with -no-rpath. + * [176029] Added qmalloc.cpp with qMalloc() and qFree() implementation + to make it easier to replace the default container allocators with + custom allocators (by providing your own qmalloc.o(bj) file). + * Enable -reduce-exports automatically on linux-icc* mkspecs when + using version 10.1 of the Intel C++ Compiler for Linux. + * Add experimental support for the AVR32 processor. + * Allow building Qt with -release and the Intel C++ Compiler for + Linux. This required working around several compiler bugs by + turning optimizations off for certain modules. See the compiler + notes for more details. + * Add support for MSVC 2008, and add separate mkspecs for MSVC 2002 & + 2003. + * [189185] Avoid quoting the the include and library paths for iconv. + +- Documentation and Examples + * The Qt Designer Manual was updated to include new Qt Designer features. + * QtScript module overview was updated with more examples and reference + material. + * [161404] The 40000 Chips demo no longer shifts when clicking the OpenGL + button. + * [188676] Fixed text item moving in Diagram Scene example. + * New demo: Embedded Dialogs + * New demo: Browser + * New example: Graphics View / Pad Navigator + * New example: Item Views / Address Book + * New example: WebKit / Previewer + * New Example: XmlPatterns / Recipes + * New tutorial: Address Book + * Multiple bug fixes for the Torrent Client example. + * Speed-ups in the Ported Asteroids Example. + * [164223] All examples that use resources now include + Q_INIT_RESOURCES to avoid breakage in static builds. + +- Translations + * Added a Traditional Chinese translation of the Qt and tools courtesy + of Franklin. + * Added a Spanish translation of Qt courtesy of Enrique Matias Sanchez. + +- Signals and slots + * [147681] Added support for 'long long' and 'unsigned long long' + in queued connections. + * [125987] Optimized QMetaObject::activate(), the function that + actually delivers signals to all connected slots. + * [164558] Fixed a bug that caused queued signals to be delivered out + of order (not in the order they are emitted). + * [169554] Added Q_EMIT, to correspond to Q_SIGNAL and Q_SLOT. + +- Multithreaded painting + * [66358, 142031] Added support for painting on QImage, QPicture, + and QPrinter in multiple threads. See the Multithreaded + Programming documentation for more details on supported features + and known limitations. + +- Embedded QWidget support for Graphics View + * [177204] Added support for using layouts, styles, palettes and fonts, + as well as embedding QWidgets into a QGraphicsScene. + +- XML support in QtCore + * The QXmlStreamReader, QXmlStreamWriter and supporting classes + have moved from the QtXml module to the QtCore module. This change is + both source- and binary-compatible with previous versions. New + applications can opt to not link to QtXml when using these classes. + +- Printing + Made a number of improvements to printing in Qt 4.4, including + support for setting custom page sizes and custom margins as well as + the ability to programatically enumerate printers via the new + QPrinterInfo class.

Previously, thread affinity was ignored when adding, + removing, and activating an object's event filters. Now, event + filters must have the same thread affinity as the object they + are filtering. Qt will warn when it detects a filter that is + in a different thread from the object being filtered. + +- QFont + Starting with Qt 4.4, the '-' characters in the raw font names + are no longer substituted with a ' ' (space character). This + may impact your application if you use fonts that have '-' + characters in their raw font names. + +- QReadWriteLock + Starting with Qt 4.4, recursive lock support is disabled by + default in QReadWriteLock. Code that relies on recursive write + locking will need to be changed to construct the + QReadWriteLock with recursive lock support enabled. Previously, + recursive write-lock support (introduced in 4.3) was enabled by + default, but QReadWriteLock did not properly support recursive + read-lock support. QReadWriteLock now supports both and needs to + be constructed explicitly with recurive lock support enabled + (QMutex works in the same way). + +- QPainterPath + We have changed QPainterPath::angleAtPercent() to use the same + angle definition as in the rest of Qt. This means that the angle + returned will be from 0 to but not including 360, specifying + the degrees from the 3 o'clock position in the counter-clockwise + direction. + +- QDirectPainter [Qt for Embedded Linux-specific class] + startPainting() in Qt 4.3 had a default parameter lock=false, + the value of which was not used. The function would lock for + client processes, but not for the server process. From Qt 4.4, + the default value is changed to true, and startPainting() will + lock if lock == true, and not lock if lock == false. This means + that client processes running code that has not been recompiled + with Qt 4.4 may show flicker and/or painting problems. To get + exactly the same behaviour as for Qt 4.3, change startPainting() + to startPainting(QApplication::type() == QApplication::GuiClient). + +- QPrinter + QPrinter::pageRect() did not return consistent values on + Linux/Mac/Windows when QPrinter::fullPage() was set to true. On + Mac and Windows pageRect() was not influenced by the fullPage() + setting. This has now been changed so that pageRect() returns + the same as paperRect() when fullPage() is true on all + platforms. + +- QPixmap + Using QPixmap outside of the GUI thread is dangerous and error + prone. Because of this, starting with 4.4, any QPixmap created + outside of the GUI thread will always be a null pixmap. + +- QDateTime + When using QDateTime::fromString() to parse dates, QDateTime + no longer tries to use English month names because that would + cause some dates to become unparseable. If you need to parse + date times in the English locale, use QLocale::toDateTime (in + specific, the QLocale::c() locale). + +- Qt/Mac + Starting a Qt application no longer makes it the front process. This is + more in-line with other applications on Mac OS X. What this means is + that you can start a Qt application, do something else and not have the + Qt application steal your focus. If you desire for the Qt application + to become the front process, you can call QWidget::raise() + programmatically or launch the application with open(1) or using + QDesktopServices. This should not have any affect if launched from + double-clicking in Finder or run in a debugger. + +- Qt/X11 on MIPS Linux + qreal is changed from float to double, breaking binary compatibility. + This change fixes a bug introduced in Qt 4.3.0 when qreal was + changed from double to float for embedded MIPS processors. |
