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. A couple of new classes, QPrintPreviewWidget+
−
      and QPrintPreviewDialog, have been added to make it easy to add a+
−
      print preview to an application. The QPrintDialog and QPageSetupDialog+
−
      for X11 have been redesigned and are hopefully easier to use.+
−
+
−
New features+
−
------------+
−
+
−
- XQuery 1.0 and XPath 2.0 support provided through the new QtXmlPatterns+
−
  module.+
−
+
−
- Qt Help module for embedding documentation into applications.+
−
+
−
- QSystemSemaphore provides a general counting system semaphore.+
−
+
−

−
  threads and processes.+
−
+
−
- QLocalServer class provides a local socket-based server with a matching+
−
  new QLocalSocket class.+
−
+
−
- QFileSystemModel provides a data model for the local file system. Unlike+
−
  QDirModel, QFileSystemModel will fetch directory listings in a background+
−
  thread to prevent any locking in the GUI. QFileSystemModel is also much+
−
  faster and has a few more features then QDirModel.+
−
+
−
- QCommandLinkButton to support Vista style command links on all platforms.+
−
+
−
- QFormLayout provides a layout designed for convenient form creation with+
−
  the appropriate appearance on different platforms. This class previously+
−
  appeared in Qtopia/4.3, but has been integrated into Qt.+
−
+
−
- QtConcurrent provides a high level multi-threading API.+
−
+
−
- QPlainTextEdit provides a highly scalable plain text editor. It uses+
−
  similar technology and concepts as QTextEdit, but is optimized for plain+
−
  text handling; e.g. as a log viewer.+
−
+
−
- QTextBoundaryFinder is a new class implementing the Unicode text+
−
  boundaries specification.+
−
+
−
+
−
Third party components+
−

−
****************************************************************************+
−
+
−
- Event filters+
−
+
−
        The behavior of event filters has changed starting with+
−
        4.4. 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.+
