23General Improvements
24--------------------
25
26- Legal
27    * This version introduces the GPL version 3 as an alternative
28      license for the Open Source Edition of Qt, in addition to the
29      existing licenses.
30    * Updated the GPL Exception to version 1.2, which grants additional
31      rights to developers using the LGPL version 3.0 and other licenses
32      for their software.
33
34- Configuration/Compilation
35    * [102113, 151125] Make it possible to use Qt headers with MSVC's
36      warning level 4.
37    * [129841] Make Qt compile with Intel C++ 9.0 and Intel C++ 10 compilers
38      on Windows.
39    * [168868] Add experimental support for the Blackfin processor.
40    * [188167] Fixed a bug in the solaris-cc mkspec that would cause
41      it to always use RPATH, even when configured with -no-rpath.
42    * [176029] Added qmalloc.cpp with qMalloc() and qFree() implementation
43      to make it easier to replace the default container allocators with
44      custom allocators (by providing your own qmalloc.o(bj) file).
45    * Enable -reduce-exports automatically on linux-icc* mkspecs when
46      using version 10.1 of the Intel C++ Compiler for Linux.
47    * Add experimental support for the AVR32 processor.
48    * Allow building Qt with -release and the Intel C++ Compiler for
49      Linux. This required working around several compiler bugs by
50      turning optimizations off for certain modules. See the compiler
51      notes for more details.
52    * Add support for MSVC 2008, and add separate mkspecs for MSVC 2002 &
53      2003.
54    * [189185] Avoid quoting the the include and library paths for iconv.
55
56- Documentation and Examples
57    * The Qt Designer Manual was updated to include new Qt Designer features.
58    * QtScript module overview was updated with more examples and reference
59      material.
60    * [161404] The 40000 Chips demo no longer shifts when clicking the OpenGL
61      button.
62    * [188676] Fixed text item moving in Diagram Scene example.
63    * New demo: Embedded Dialogs
64    * New demo: Browser
65    * New example: Graphics View / Pad Navigator
66    * New example: Item Views / Address Book
67    * New example: WebKit / Previewer
68    * New Example: XmlPatterns / Recipes
69    * New tutorial: Address Book
70    * Multiple bug fixes for the Torrent Client example.
71    * Speed-ups in the Ported Asteroids Example.
72    * [164223] All examples that use resources now include
73      Q_INIT_RESOURCES to avoid breakage in static builds.
74
75- Translations
76    * Added a Traditional Chinese translation of the Qt and tools courtesy
77      of Franklin.
78    * Added a Spanish translation of Qt courtesy of Enrique Matias Sanchez.
79
80- Signals and slots
81    * [147681] Added support for 'long long' and 'unsigned long long'
82      in queued connections.
83    * [125987] Optimized QMetaObject::activate(), the function that
84      actually delivers signals to all connected slots.
85    * [164558] Fixed a bug that caused queued signals to be delivered out
86      of order (not in the order they are emitted).
87    * [169554] Added Q_EMIT, to correspond to Q_SIGNAL and Q_SLOT.
88
89- Multithreaded painting
90    * [66358, 142031] Added support for painting on QImage, QPicture,
91      and QPrinter in multiple threads. See the Multithreaded
92      Programming documentation for more details on supported features
93      and known limitations.
94
95- Embedded QWidget support for Graphics View
96    * [177204] Added support for using layouts, styles, palettes and fonts,
97      as well as embedding QWidgets into a QGraphicsScene.
98
99- XML support in QtCore
100    * The QXmlStreamReader, QXmlStreamWriter and supporting classes
101      have moved from the QtXml module to the QtCore module. This change is
102      both source- and binary-compatible with previous versions. New
103      applications can opt to not link to QtXml when using these classes.
104
105- Printing
106      Made a number of improvements to printing in Qt 4.4, including
107      support for setting custom page sizes and custom margins as well as
108      the ability to programatically enumerate printers via the new
109      QPrinterInfo class. A couple of new classes, QPrintPreviewWidget
110      and QPrintPreviewDialog, have been added to make it easy to add a
111      print preview to an application. The QPrintDialog and QPageSetupDialog
112      for X11 have been redesigned and are hopefully easier to use.
113
114New features
115------------
116
117- XQuery 1.0 and XPath 2.0 support provided through the new QtXmlPatterns
118  module.

127- QLocalServer class provides a local socket-based server with a matching
128  new QLocalSocket class.
129
130- QFileSystemModel provides a data model for the local file system. Unlike
131  QDirModel, QFileSystemModel will fetch directory listings in a background
132  thread to prevent any locking in the GUI. QFileSystemModel is also much
133  faster and has a few more features then QDirModel.
134
135- QCommandLinkButton to support Vista style command links on all platforms.
136
137- QFormLayout provides a layout designed for convenient form creation with
138  the appropriate appearance on different platforms. This class previously
139  appeared in Qtopia/4.3, but has been integrated into Qt.
140
141- QtConcurrent provides a high level multi-threading API.
142
143- QPlainTextEdit provides a highly scalable plain text editor. It uses
144  similar technology and concepts as QTextEdit, but is optimized for plain
145  text handling; e.g. as a log viewer.
146
147- QTextBoundaryFinder is a new class implementing the Unicode text
148  boundaries specification.
149
150

527    * [160653] selectionChanged is now emitted when reselecting an already
528    selected item.
529    * QGraphicsScene::mouseMoveEvent now receives all mouse move events from
530    the views, and translates them into hover events for the items. This
531    allows you to track all mouse move events for the entire scene, without
532    having to reimplement QGraphicsScene::event() and duplicating the
533    QGraphicsScene implementation.
534

575- QHash
576    * [171909] Don't rehash in operator[] and insert() when the key already
577      exists -- to avoid subtle bugs when iterating on a QHash. (This is
578      documented as being undefined, since these functions are non-const,
579      but it's easy to avoid the rehashing.)
580
581- QHeaderView
582    * [173773] QHeaderView now updates properly upon sorting a column.
583    * [192884] When the model emits layout changed unhide old hidden rows

625    * Added support for the ICO image format (from Qt Solutions)
626    * Fix drawing of text into a QImage on the Mac so that the native
627      CoreGraphics engine is used. This makes aliased text, or text with
628      a small point size, look much better.
629    * [188102] For Indexed image, fixed setColor() to expand the
630      colortable if necessary. Made colortable manipulation more robust.

653
654- QLayout
655    * Cache sizeHint() and minimumSizeHint() of widgets in a layout using
656      the internal class QWidgetItemV2, leading to significant performance
657      gains for widgets that have an expensive size hint implementation.

661    * [170013] Make sure that libraries are opened with RTLD_LOCAL by default
662      on *all* platforms.  (On Mac it was RTLD_GLOBAL by default). This should
663      make plugin loading more consistent.
664    * [190831] Fixed crash when calling loadHints on a default constructed
665      QLibrary.
666    * [155109] The real error message was discarded if the library existed,

677    * [151414] Add protected function to access the cursor rectangle.
678    * [153563] Don't show blinking cursor on read only line edit with input mask
679    * [174640] Emit editingFinished() when the user open a menu.
680    * [178752] Reverted to Qt3's behavior of using an arrow cursor instead of
681      a beam cursor when the QLineEdit is read only.
682    * [180999] Old selection now cleared upon activating a window.
683    * [188877] Fixed painting error resulting from pasting into a selection.

1687    * [193845] Improved support for KDE palette settings.
1688    * [179200] Fixed an issue where Qt would print "QProcess: Destroyed
1689      while process is still running." when using Cleanlooks.
1690    * [155704] Fixed a bug where widgets with MSWindowsFixedSizeDialogHint
1691      flag would be minimized when their parent QMainWindow was minimized.
1692      The MSWindowsFixedSizeDialogHint is now ignored on X11.
1693    * [153155] Make it possible to bypass g_thread_init() and have the
1694      Unix event dispatcher be used in threads instead by setting the
1695      QT_NO_THREADED_GLIB environment variable.
1696    * [157807] Fix an inefficiency in the Glib dispatcher's
1697      timerSourcePrepare() implementation.

1700    * [166097] QWidget::show() no longer resets the WM_TRANSIENT_FOR
1701      property if the Qt::WA_X11BybassTransientForHint attribute is
1702      set.
1703    * [166097] QWidget::show() no longer resets the _NET_WM_STATE
1704      property. Qt now merges its own state with any previous state
1705      set by the application programmer.
1706    * [168285] Fixed QDrag to correctly reset the override cursor.
1707    * [17566] Don't impose FD_SETSIZE limit when using the Glib event

1721      the Glib event dispatcher.
1722    * [182913] Qt will now always look for the _MOTIF_DRAG_WINDOW
1723      property on screen 0 (instead of the default screen).
1724    * [187752] Fixed a bug where calling show() and hide() on a window
1725      before the event loop starts would prevent the window from ever
1726      being shown.
1727    * [189045] Reset the keyboard and mouse grabs to the current
1728      grabber when the last popup is closed.
1729    * [167707] Add support for all known _NET_WM_WINDOW_TYPE_* types

1731      Qt::WA_X11NetWmWindowType* naming scheme.
1732    * [172623] Don't create a pipe in the Glib event dispatcher (as it
1733      is not necessary).

1735      broke QX11EmbedContainer.
1736    * [192526] Similar to 170768 below, fixed the spin locking in the
1737      QAtomic* implementation for 32-bit SPARC processors to yield
1738      instead of busy waiting.
1739    * [194566] Fixed a bug found in the 4.4.0 snapshots that would
1740      always cause the cursor to change when QWidget::setCursor() was
1741      called on a widget that was not under the mouse.
1742    * [173746] Fixed a bug in QDialog that would cause the "What's
1743      This?" popup menu to appear on the wrong X11 screen.

1745      cause the positioning to be incorrect.
1746    * [160206] Fixed some bugs in QX11EmbedWidget and
1747      QX11EmbedContainer to provide minimal support for multiple

1751      _MOTIF_DRAG_WINDOW property is missing.
1752    * [183477] Fixed a bug that would cause a window to disappear

1768      under X11.
1769    * [176485] Make drawing text through FreeType beyond the SHORT_MIN/MAX

1780    * Redesigned the print dialog and pagesetup dialog to be much nicer.
1781
1782- QPrinter
1783    * [148125] Switched to printing through the CUPS API. This should fix the
1784      problem where the wrong lp/lpr command was picked up, and therefore
1785      printed through the wrong print system. If CUPS is enabled at compile
1786      time, it will always be used if available.
1787    * [161936] lp no longer outputs job ID to the console when printing.
1788    * [180669] QPrinter no longer crashes if the CUPS library cannot be found.

2338****************************************************************************
2339*                   Important Behavior Changes                             *
2340****************************************************************************
2341
2342- Event filters
2343
2344        The behavior of event filters has changed starting with
2345        4.4. Previously, thread affinity was ignored when adding,
2346        removing, and activating an object's event filters. Now, event
2347        filters must have the same thread affinity as the object they
2348        are filtering. Qt will warn when it detects a filter that is
2349        in a different thread from the object being filtered.
2350
2351- QFont
2352        Starting with Qt 4.4, the '-' characters in the raw font names
2353        are no longer substituted with a ' ' (space character). This
2354        may impact your application if you use fonts that have '-'
2355        characters in their raw font names.
2356
2357- QReadWriteLock
2358        Starting with Qt 4.4, recursive lock support is disabled by
2359        default in QReadWriteLock. Code that relies on recursive write
2360        locking will need to be changed to construct the
2361        QReadWriteLock with recursive lock support enabled. Previously,
2362        recursive write-lock support (introduced in 4.3) was enabled by
2363        default, but QReadWriteLock did not properly support recursive
2364        read-lock support. QReadWriteLock now supports both and needs to
2365        be constructed explicitly with recurive lock support enabled
2366        (QMutex works in the same way).
2367
2368- QPainterPath
2369        We have changed QPainterPath::angleAtPercent() to use the same
2370        angle definition as in the rest of Qt. This means that the angle
2371        returned will be from 0 to but not including 360, specifying
2372        the degrees from the 3 o'clock position in the counter-clockwise
2373        direction.
2374
2375- QDirectPainter [Qt for Embedded Linux-specific class]
2376        startPainting() in Qt 4.3 had a default parameter lock=false,
2377        the value of which was not used. The function would lock for
2378        client processes, but not for the server process. From Qt 4.4,
2379        the default value is changed to true, and startPainting() will
2380        lock if lock == true, and not lock if lock == false. This means
2381        that client processes running code that has not been recompiled
2382        with Qt 4.4 may show flicker and/or painting problems. To get
2383        exactly the same behaviour as for Qt 4.3, change startPainting()
2384        to startPainting(QApplication::type() == QApplication::GuiClient).
2385
2386- QPrinter
2387        QPrinter::pageRect() did not return consistent values on
2388        Linux/Mac/Windows when QPrinter::fullPage() was set to true. On
2389        Mac and Windows pageRect() was not influenced by the fullPage()
2390        setting. This has now been changed so that pageRect() returns
2391        the same as paperRect() when fullPage() is true on all
2392        platforms.
2393
2394- QPixmap
2395        Using QPixmap outside of the GUI thread is dangerous and error
2396        prone. Because of this, starting with 4.4, any QPixmap created
2397        outside of the GUI thread will always be a null pixmap.
2398
2399- QDateTime
2400        When using QDateTime::fromString() to parse dates, QDateTime
2401        no longer tries to use English month names because that would
2402        cause some dates to become unparseable. If you need to parse
2403        date times in the English locale, use QLocale::toDateTime (in
2404        specific, the QLocale::c() locale).
2405
2406- Qt/Mac
2407        Starting a Qt application no longer makes it the front process. This is
2408        more in-line with other applications on Mac OS X. What this means is
2409        that you can start a Qt application, do something else and not have the
2410        Qt application steal your focus. If you desire for the Qt application
2411        to become the front process, you can call QWidget::raise()
2412        programmatically or launch the application with open(1) or using
2413        QDesktopServices.  This should not have any affect if launched from
2414        double-clicking in Finder or run in a debugger.
2415
2416- Qt/X11 on MIPS Linux
2417        qreal is changed from float to double, breaking binary compatibility.
2418        This change fixes a bug introduced in Qt 4.3.0 when qreal was
2419        changed from double to float for embedded MIPS processors.
2420
