    23 General 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 

   114 New features

   115 ------------

   116 

   117 - XQuery 1.0 and XPath 2.0 support provided through the new QtXmlPatterns

   118   module.

   119 

   120 - Qt Help module for embedding documentation into applications.

   121 

   122 - QSystemSemaphore provides a general counting system semaphore.

   123 

   124 - QSharedMemory provides access to a shared memory segment between multiple

   125   threads and processes.

   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

   393       inactive state when the cursor have passed over it.

   394 

   395 - QDoubleSpinBox

   396     * [164696] QWidget::locale() is now used for all string-to-number

   397       conversions.

   398 

   399 - QErrorMessage

   400     * [189429] Fixed "do not show again" with rich text message.

   404       event type ID.

   405     * [161940] Fix QContextMenuEvent::modifiers() on X11 and Qt for Embedded

   406       Linux to behave like the Windows and Mac OS X. Previously, this

   407     * [166605] A drop event's drop action is now initialized to the drag

   408       manager's current default action.

   409

   418       will be deleted, not just the current one.

   419     * [172254] selectFile should also set the current directory.

   420     * [185930] getExistingDirectory directory file not updated after

   421       renaming the new directory.

   422     * [164591] Provided a way to set the QDir::filter on the model.

   442       text to a QPainterPath.

   443 

   444 - QFSFileEngine

   445     * [200220] Fixed a potential crash and removed some potential resource

   446       leaks.

   447     * [190377] Fixed a reentrancy bug on all platforms; querying the canonical

   468 

   469 - QGLWidget

   470     * [128157] QPixmap::grabWidget() now works on a QGLWidget.

   471     * Added support for syncing drawing to QGLWidgets under X11 via the

   472       QGLFormat::setSwapInterval() mechanism. This requires the

   473       GLX_SGI_video_sync extension to be present.

   474     * [183472] Made renderText() respect the currently set GL scissor box

   475       and GL viewport.

   490       coordinates.

   491     * [183996] Fixed a bug caused when items are moved by pressing many mouse

   492       buttons at the same time.

   493     * [192983] Added QGraphicsItem::boundingRegion(), which allows updating

   494       items based on their shape instead of their bounding rect.

   495     * Improved QGraphicsItem::isObscured() and QGraphicsItem::opaqueArea()

   496       speed and accuracy.

   497     * [195916] Fixed crash when deleting an item as it receives a

   498       contextMenuEvent().

   507 

   508 - QGraphicsLineItem

   511 

   512 - QGraphicsScene

   513     * [160463] QGraphicsScene::clearSelection() is now a slot.

   514     * [161284] Added Q_DISABLE_COPY.

   516     grabber item.

   517     * [176902] Add support for context menu event propagation.

   518     * [176178] QGraphicsScene::sceneRect() now auto-updates also with NoIndex

   519       set.

   521       recursive scene destruction.

   522     * [180663] Fixed miscalculated expose rects in QGraphicsScene::render().

   523     * [176124] Ensure that all mouse events that should have a widget assigned

   524       do have a widget assigned.

   525     * [174238] The selectionChanged() signal is no longer emitted twice when

   526       replacing one selection with another.

   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 

   535 - QGraphicsSceneHoverEvent

   548     * [164025] Mouse press events now propagate through the view if ignored

   549       by the scene.

   550     * New ViewportUpdateMode: QGraphicsView::BoundingRectViewportUpdate

   551     * [180429] Mouse release events propagate properly in RubberBandDrag

   552       mode.

   556       properly.

   557     * [186827] Fixed an infinite loop caused by mouse replay after deleting

   558       items in response to receiving mouse move events.

   559     * [172231] Fixed erroneous clipping of untransformable items by scaled

   560       graphics view.

   562       OpenGL viewport.

   563 

   564 - QGridLayout

   565     * [121549] Added itemAtPosition(int, int).

   566 

   567 - QGroupBox

   568     * [159480] QGroupBox's clicked() behavior is now the same as QCheckBox.

   569     * [186297] Right-clicking a checkable group box now has no effect, which

   570       is consistent with the behavior of QCheckBox.

   571     * [178797] A checkable group box now correctly updates the sunken state

   572       of its check box.

   573     * Don't call updateGeometry() needlessly from resizeEvent().

   574 

   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

   590 

   591 - QHostInfo

   592     * [194539] Fixed the ordering of IP addresses returned by the

   593       host-lookup procedures. Qt respects the order supplied by the

   594       system libraries.

   595     * [176527] Fixed a problem in QHostInfo that would cause it to

   596       print warnings if it was used before QCoreApplication is created

   597 

   598 - QHttpHeaders

   599     * [104648] Fixed QHttpHeaders to not change the order or

   600       capitalisation of headers received or sent. QHttpHeaders is now

   601       case-insensitive but case-preserving

   602 

   603 - QHttp

   604     * [181506] Fixed a bug that would cause QHttp to emit a warning

   609       found in 304 replies)

   610     * [170860] Fixed a problem which would make QHttp emit the done()

   611       signal too soon (before it was finished).

   612 

   613 - QIcon

   614     * [168488] Reduce memory usage if you call addPixmap severals times with the same arguments.

   615 

   616 - QImage

   617     * [176566] Fixed problem in scale() which would cause downscaled images to

   618       become darker due to precision loss in the image scaling.

   619     * [181265] Fixed crash in scale() when downscaling very large images.

   620     * Added new image formats: QImage::Format_ARGB8565_Premultiplied,

   621       QImage::Format_RGB666, QImage::Format_ARGB6666_Premultiplied,

   622       QImage::Format_RGB555, QImage::Format_ARGB8555_Premultiplied,

   623       QImage::Format_RGB444, QImage::Format_ARGB4444_Premultiplied,

   624       and QImage::Format_RGB888.

   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.

   631 

   632 - QImageReader

   633 

   634 - QImageWriter

   635 

   636 - QInputDialog

   637 

   638 - QIntValidator

   639     * [179131] Reverted QIntValidator's out-of-range semantics to Qt 4.2

   640       behavior, at popular demand.

   641 

   642 - QItemDelegate

   643     * [175982] Escape did not close the editor if the application had registered

   644       escape as a shortcut.

   645     * [177039] Handle double precision properly.

   646     * Don't finish editing if the validator is still in intermediate mode.

   647 

   648 - QItemSelectionModel

   649     * [169285] Items are now deselected properly.

   650     * [192147] Fix an off-by-one bug in QItemSelectionModel

   651 

   652 - QLabel

   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.

   658 

   659 - QLibrary

   660     * [155884] Fixed QPluginLoader to not load plugins with unresolved symbols.

   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,

   667       but failed for another reason.

   668 

   669 - QLineF

   670     * [170170] Introduce new member function angleTo() which returns the angle

   671       between two lines, also taking the direction into account.

   672     * [174122] Added new member functions in QLineF for setting and getting

   673       the angle of the line, as well as translating a line, and constructing

   674       a line from polar coordinates.

   675 

   676 - QLineEdit

   677     * [151414] Add protected function to access the cursor rectangle.

   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.

   684 

   685 - QLinkedList

   687     value from the list.

   688 

   689 - QList

   690     * Add QList::removeOne(), which removes the first occurrence of a value

   691     from the list.

   708     * Added the following functions to QLocale:

   709         QString toString(const QDateTime &dateTime, FormatType format = LongFormat) const;

   710         QString toString(const QDateTime &dateTime, const QString &format) const;

   711         QString dateTimeFormat(FormatType format = LongFormat) const;

   712     * Added the following enum values to QLocale::QueryType:

   713         DateTimeFormatLong

   714         DateTimeFormatShort

   719     * [142746] Now respects the QComboBox::iconSize property.

   720     * [184566] Make sure we pick up changes to QPushButton::setDefault().

   721     * [174284] Don't truncate text on tabs in the small and mini size.

   722     * [170971] Don't try to draw a mini scrollbar as it doesn't exist, draw a small one instead.

   723     * [170977] Correct checkmarks for small and mini non-editable comboboxes.

   724     * [170978] Prevent mini push buttons from being clipped.

   725     * [202959] Draw the correct number of tickmarks for sliders.

   726
