++

++ New features

++ ------------

++

++ - QCalendarWidget provides a standard monthly calendar widget with date

++   selection features.

++

++ - QCleanlooksStyle provides the new Cleanlooks style, a clone of the GNOME

++   ClearLooks style, giving Qt applications a native look on GNOME desktops.

++

++ - QCompleter provides facilities for auto completion in text entry widgets.

++

++ - QDataWidgetMapper can be used to make widgets data-aware by mapping them

++   to sections of an item model.

++

++ - QDesktopServices provides desktop integration features, such as support

++   for opening URLs using system services.

++

++ - QDialogButtonBox is used in dialogs to ensure that buttons are placed

++   according to platform-specific style guidelines.

++

++ - QFileSystemWatcher enables applications to monitor files and directories

++   for changes.

++

++ - QFontComboBox provides a standard font selection widget for document

++   processing applications.

++

++ - QGraphicsView and related classes provide the Graphics View framework, a

++   replacement for Qt 3's canvas module that provides an improved API, enhanced

++   rendering, and more responsive handling of large numbers of canvas items.

++

++ - QGLFramebufferObject encapsulates OpenGL framebuffer objects.

++

++ - QMacPasteboardMime handles Pasteboard access on Qt/Mac. This obsoletes

++   QMacMime as the underlying system has changed to support Apple's new

++   Pasteboard Manager. Any old QMacMime objects will not be used.

++

++ - QNetworkInterface represents a network interface, providing information

++   about the host's IP addresses and network interfaces.

++

++ - QResource provides static functions that control resource lookup and

++   provides a way to navigate resources directly without levels of

++   indirection through QFile/QFileEngine.

++

++ - QSystemTrayIcon allows applications to provide their own icon in the

++   system tray.

++

++ - QTimeLine gives developers access to a standard time line class with which

++   to create widget animations.

++

++ - The QtDBus module provides inter-process communication on platforms

++   that support the D-BUS protocol.

++

++ - The QUndo* classes in Qt's Undo framework provide undo/redo functionality

++   for applications.

++

++ - Support for the Glib event loop to enable integration between Qt and non-Qt

++   applications on the GNOME desktop environment.

++

++ - Improved Accessibility for item-based views and QTextEdit.

++

++ - Support for main window animations and tabbed dock widgets.

++

++ - Added an SVG icon engine to enable SVG drawings to be used by QIcon.

++

++ - Widgets can now be styled according to rules specified in a style sheet,

++   using a syntax familiar to users of Cascading Style Sheets (CSS). Style

++   sheets are set using the QWidget::styleSheet property.

++

++ - Introduced a new key mapper system which improves the shortcut system by

++   only testing the real possible shortcuts, such as Ctrl+Shift+= and Ctrl++

++   on an English keyboard.

++

++ - Improved and enhanced QMessageBox to support native look and feel on many

++   common platforms.

++

++ - Experimental support for Qt usage reporting ("metered licenses") on Linux,

++   Windows and Mac OS X. Reporting is disabled by default.

++

++ - A screen magnification utility, pixeltool, is provided. It is designed to help

++   with the process of fine-tuning styles and user interface features.

++

++ - New qrand() and qsrand() functions to provide thread safe equivalents to

++   rand() and srand().

++

++

++ General improvements

++ --------------------

++

++ - Item views

++

++       * Selections are maintained when the layout of the model changes

++         (e.g., due to sorting).

++

++       * Convenience views can perform dynamic sorting of items when the data

++         in items changes.

++

++       * QStandardItem provides an item-based API for use with

++         QStandardItemModel and the model/view item view classes.

++

++       * QStandardItemModel API provides a classic item-based approach to

++         working with models.

++

++       * Single selection item views on Mac OS X cannot change their current

++         item without changing the current selection when using keyboard

++         navigation.

++

++ - Plastique style has improved support for palettes, and now requires

++   XRender support on X11 for alpha transparency.

++

++ - Tulip containers

++

++       * Added typedefs for STL compatability.

++

++       * Added function overloads to make the API easier to use.

++

++ - Added the Q3TextStream class for compatiblity with Qt 3 and to assist with

++   porting projects.

++

++ - OpenGL paint engine

++

++       * Added support for all composition modes of QPainter natively using

++         OpenGL.

++

++       * Fixed a case where very large polygons failed to render correctly.

++

++       * Ensured that glClear() is only called in begin() if the

++         QGLWidget::autoFillBackground() property is true.

++

++       * Ensured that a buffer swap is only performed in end() if

++         QGLWidget::autoBufferSwap() is true.

++

++       * Improved text drawing speed and quality.

++

++ - Raster paint engine

++

++       * Fixed blending of 8 bit indexed images with alpha values.

++

++       * Fixed drawing onto QImages that were wider than 2048 pixels.

++

++       * Fixed alpha-blending and anti-aliasing on ARGB32 images.

++

++       * Improved point drawing performance.

++

++       * Fixed issue where lines were drawn between coordinates that were

++         rounded instead of truncated.

++

++       * Ensured that setClipRegion(QRegion()) clips away all painting

++         operations as originally intended.

++

++

++ Third party components

++ ----------------------

++

++ - Dropped support for MySQL version 3.

++

++ - Updated Qt's SQLite version to 3.3.6.

++

++ - Updated Qt's FreeType version to 2.2.1.

++

++ - Updated Qt's libpng version to 1.2.10.

++

++

++ Build System

++ ------------

++

++ - Auto-detect PostgreSQL and MySQL using pg_config and mysql_config on UNIX

++   based systems in the configure script

++

++ - Added "-system-sqlite" option to configure to use the system's SQLite

++   library instead of Qt's SQLite version.

++

++ - Added QT_ASCII_CAST_WARNINGS define that will output a warning on implicit

++   ascii to Unicode conversion when set. Only works if the compiler supports

++   deprecated API warnings.

++

++ - Added Q_REQUIRED_RESULT to some functions. This macro triggers a warning

++   if the result of a function is discarded. Currently only supported by gcc.

++

++

++ - Qt/X11, Qt/Mac and Qtopia Core only:

++

++      * Added all QT_NO_* defines to the build key.

++

++

++ - Qt/X11 and Qtopia Core only:

++

++      * As in Qt 3, the configure script enables the -release option by

++        default, causing the Qt libraries to be built with optimizations. If

++        configured with the -debug option, the debug builds no longer result

++        in libraries with the _debug suffix.

++

++        On modern systems, flags are added to the Qt build to also

++        generate debugging information, which is then stored in a

++        separate .debug file. The additional debug information does not

++        affect the performance of the optimized code and tools like gdb

++        and valgrind automatically pick up the separate .debug

++        files. This way it is possible to get useful backtraces even

++        with release builds of Qt.

++

++      * Removed the last vestiges of the module options in the configure

++        script, previously they were available but did not function.

++

++      * Implemented a -build option in the configure script to conditionally

++        compile only certain sections of Qt.

++

++      * Made it possible to build Qt while having "xcode" set as your

++        QMAKESPEC on OSX.

++

++

++ - Windows only:

++

++      * Populated the build key, as done on all the other platforms.

++

++      * Fixed dependency generation in Visual Studio Solutions (.sln)

++        created by qmake.

++

++      * Added missing platforms to the Visual Studio project generator (X64,

++        SH3DSP and EBC).

++

++      * Made UIC3 use a temporary file for long command lines.

++

++      * Removed the object file (.o) conflicts with MinGW that appeared when

++        embedding a native resource file which was named the same as a normal

++        source file.

++

++      * Fixed mkspec detection when generating project files outside of QTDIR.

++

++      * Removed compiler warnings with MinGW g++ 3.4.5.

++

++       * Added dragDropMode property and implemented move support in all of

++         the views and models.

++

++       * For edit triggers SelectedClicked and DoubleClicked, only trigger

++         editing when the left button is clicked.

++

++       * Trigger SelectedClicked editing on mouse release, not mouse press.

++

++       * Suppressed the doubleClicked() signal in cases where the clicks

++

++       * Made it possible to check a checkbox with only a single click when

++         using the CurrentChanged edit trigger.

++

++       * Ensured that WhatsThis events are propagated when the relevant item

++         doesn't have a valid "What's This?" value.

++         resizing the header section. This includes the stretchLastSection

++         property.

++

++       * Added the minimumSectionSize property.

++

++       * Get the section size hint from the Qt::SizeHintRole, if set.

++

++       * Added the ResizeToContents resize mode.

++

++ - QHttp

++

++       * Support percent-encoded paths when used with a proxy server.

++

++       * Improved handling of unexpected remote socket close.

++

++ - QHttpHeader

++

++       * Improved support for case-insensitive header searching.

++

++ - QIcon

++

++       * Fixed issue where actualSize() might return a larger value than the

++         requested size.

++

++       * Fixed improper pixmap caching

++

++       * Added QDataStream operators for QIcon.

++

++       * Added the Selected mode.

++

++       * Added QPoint overloads to various (int x, int y) functions.

++

++       * Added support for faster/better rotation of images by 90/180/270

++         degrees.

++

++       * convertToFormat() now supports the color lookup table.

++

++       * Improved algorithm for smooth scaling to produce better results.

++

++ - QImageReader

++

++       * Ensured that size() returns an invalid QSize if the image I/O handler

++         does not support the QImageIOHandler::Size extension.

++

++       * Added support for reading negative BMP images.

++

++       * Improved handling of invalid devices.

++

++       * Added optimizations to ensure that the most likely formats and plugins

++         are tested first when reading unknown image formats.

++

++       * Improved reading of BMP images from sequential QIODevices.

++

++       * Support for scaledSize() with JPEG images.

++

++       * It is now possible to query the supported options of an image by

++         calling supportedOptions().

++

++       * Stability fixes for the built-in XBM reader.

++

++ - QImageWriter

++

++       * Ensured that an error is reported when attempting to write an image

++         to a non-writable device.

++

++       * It is now possible to query the supported options of an image by

++         calling supportedOptions().

++

++ - QIODevice

++

++       * Fixed a casting bug in QIODevice::getChar().

++

++       * Improved reading performance significantly by using an internal buffer

++         when a device is opened in buffered mode.

++

++       * Some behavioral differences have been introduced:

++

++         + The following functions now need to call the base implementation

++           when reimplemented: atEnd(), bytesAvailable(), size(), canReadLine().

++

++         + pos() should return the base implementation directly.

++

++         + QIODevice now handles the device position internally. seek() should

++           always end up calling the base implementation.

++

++ - QItemDelegate

++

++       * Use a widget's USER property to set and get the editor data.

++

++       * Removed unnecessary assertions.

++

++       * Added the clipping property to enable clipping when painting.

++

++       * When the model specifies a font, resolve the font over the existing

++         one rather than replacing it.

++

++       * Fixed issue with rendering of selected pixmaps.

++

++       * Ensured that QItemEditorFactory is called with the variant's

++         userType() so that the factory can distinguish between multiple user

++         types.

++

++       * Ensured that Key_Enter is propagated to the editor before data is

++         committed, so that the editor has a chance to perform custom input

++         validation/fixup.

++

++       * Let the line edit grow to accomodate long strings.

++

++       * Made it easer to subclass the item delegate.

++

++       * Added support for keypad navigation.

++

++ - QItemSelectionModel

++

++       * Improved overall speed, particularly when isSelected() is used.

++

++       * Added functions for getting the selected rows or columns.

++

++       * Ensured that the current index is updated when it is being removed.

++

++       * Ensure that QAbstractItemView::clearSelection() only clears the

++         selection and not the current index.

++

++       * Added the hasSelection() function.

++

++       * Fixed some connection leaks (connections were not disconnected) when

++         an QItemSelectionModel was deleted. This should also speed up some

++         special cases.

++

++ - QKeySequence

++

++       * Added a set of platform-dependent standard shortcuts.

++

++       * Fixed incorrect parsing of translated modifiers.

++

++ - QLabel

++

++       * Added support for text selection and hyperlinks.

++

++       * Improved handling of scaled pixmaps.

++

++       * Made handling of QMovie safer to avoid object ownership issues.

++

++ - QLibrary

++

++       * Added support for hints to control how libraries are opened on UNIX

++         systems.

++

++       * Added errorString() to report the causes of errors when libraries

++         fail to load.

++

++       * Added easier way to debug plugin loading: Setting QT_DEBUG_PLUGINS=1

++         in the environment will enable debug message printing on the

++         console.

++

++       * Increased the number of acceptable file name suffixes used to

++         recognize library files.

++

++ - QLineEdit

++

++       * Ensured that the Unicode context menu gets shown if language

++         extensions are present.

++

++       * Ensured that editingFinished() is not emitted if a validator is set

++         and the text cannot be validated.

++

++       * Ctrl+A now triggers select all on all platforms.

++

++       * Call fixup on focusOut() if !hasAcceptableInput().

++

++       * Added auto-completion support with the setCompleter() function.

++

++       * Fixed painting errors when contents margins were set.

++

++       * Invalid text set using setText() can now be edited where previously

++         it had to be deleted before new text could be inserted.

++

++       * Use SE_LineEditContents to control the contents rect of each

++         QLineEdit.

++

++ - QListView

++

++       * Added the batchSize property.

++

++       * Don't un-hide currently hidden rows when new rows are inserted.

++

++       * Fixed partial repainting bug that occurred when alternatingRowColors

++         was enabled.

++

++       * Ensured that the resize mode is not reset in setViewMode() if it was

++         already set.

++

++       * Fixed crash that occurred when the first item was hidden and

++         uniformItemSizes was set.

++

++       * Added the wordWrap property for wrapping item text.

++

++       * Allow the user to select items consecutively when shift-selecting.

++

++       * Ensured that only the top item is selected when the user clicks on

++         an area with several items are stacked on top of each other.

++

++       * Optimized hiding and showing of items.

++

++       * Fixed issue where dragging an item in Snap mode did not respect the

++         scroll bar offsets.

++

++       * Fixed issue in Snap mode where a (drag and) drop did not always

++         query the item that existed in the corresponding cell for an enabled

++         Qt::ItemIsDropEnabled flag.

++

++ - QListWidget/QTreeWidget/QTableWidget

++

++       * Ensured the dataChanged() signal is emitted when flags are set on an

++         item.

++

++       * Removed unnecessary assertions.

++

++       * Added more convenience functions in QListWidget, QTableWidget and

++         QTreeWidget for selecting, hiding, showing, expanding and collapsing

++         nodes.

++

++       * Ensured that changes to items are reported.

++

++ - QLocale

++

++       * Fixed bug in the string-to-number functions which sometimes caused

++         them to fail on negative numbers which contained thousand-

++         separators.

++

++       * Implemented the numberOptions property for specifying how

++         string-to-number and number-to-string conversions should be

++         performed.

++

++ - QMainWindow

++

++       * Added support for tabbed dock widgets.

++

++       * Enhanced look and feel of dock widget handling. When a dock widget

++         hovers over a main window, the main window animates the existing

++         dock widgets and main area to show how it will accept the dock

++         widget if dropped.

++

++       * Fixed issues related to insertToolBarBreak().

++

++ - QMap

++

++       * Prevent conversion of iterator or const_iterator to bool

++         (e.g., if (map->find(value))), because the conversion always

++         returned true. Qt 4.1 code that doesn't compile because of this

++         change was most probably buggy.

++

++       * Added the uniqueKeys() function.

++

++ - QMenu

++

++       * Added the aboutToHide() signal.

++

++       * Added the isEmpty() accessor function.

++

++       * Clear menuAction() when setMenu(0)

++

++       * Added support for widgets in menus via QWidgetAction.

++

++       * Collapse multiple consecutive separators. This can be turned off

++         with the collapsibleSeparators property.

++

++       * Made scrollable menus wrap, just like non-scrollable ones.

++

++ - QMessageBox

++

++       * Updated the API to allow more than 3 buttons to be used.

++

++       * Added support to display buttons in the order required by

++         platform-specific style guidelines.

++

++       * Added support for display of informative text using the

++         informativeText property.

++

++       * Added the detailedText property to allow detailed text to be

++         displayed.

++

++       * Improved sizing of message box (especially on Mac OS X).

++

++       * Changed the behavior so that long text strings are automatically

++         wrapped.

++

++       * Updated icon handling to use QStyle::standardIcon() where possible.

++

++ - QMetaObject

++

++       * Added the userProperty() and normalizedType() functions.

++

++ - QMetaType

++

++       * Ensured that all type names are normalized before registering them.

++

++       * Added support for handling Qt's integer typedefs: qint8, qint16,

++         etc.

++

++ - QModelIndex

++

++       * Added the flags() convenience function.

++

++ - QMutexLocker, QReadLocker, and QWriteLocker

++

++       * These classes now track the state of the lock they are holding.

++         They will not unlock on destruction if unlock() has been called.

++

++ - QObject

++

++       * thread() will always return a valid thread, even if the object was

++         created before QApplication or in a non-QThread thread.

++

++       * When thread() returns zero, events are no longer sent to the object.

++         (Previous versions of Qt would send posted events to objects with no

++         thread; this does not happen in Qt 4.2).

++

++       * Added support for dynamically added properties via the new

++         property(), setProperty(), and dynamicPropertyNames() functions.

++

++       * Fixed a crash that could occur when a child deleted its sibling.

++

++ - QPainter

++

++       * Fixed a crash the occurred when drawing cosmetic lines outside the

++         paint device boundaries.

++

++       * Fixed a pixel artifact issue that occurred when drawing cosmetic

++         diagonal lines.

++

++       * Fixed opaque backgrounds so that they are identical on all

++         platforms.

++

++       * Optimized drawing of cosmetic lines at angles between 315 and 360

++         degrees.

++

++       * Added the setRenderHints() function.

++

++       * Fixed a memory corruption issue in drawEllipse().

++

++ - QPixmap

++

++       * Fixed crash caused by setting a mask or alpha channel on a pixmap

++         while it was being painted.

++

++       * Changed load() and save() to no longer require a format string.

++

++       * Ensured that grabWidget() works before the specified widget is first

++         shown.

++

++ - QPluginLoader

++

++       * Added errorString() to report the causes of errors when plugins fail

++         to load.

++

++ - QPrinter

++

++       * Added support for PostScript as an output format on all platforms.

++

++       * Significantly reduced the size of the generated output when using

++         the PostScript and PDF drivers.

++

++       * Fixed issue where fromPage()/toPage() returned incorrect values when

++         generating PDF files.

++

++       * Ensured that setOutputFormat() preserves previously set printer

++         properties.

++

++       * Updated setOutputFileName() to automatically choose PostScript or

++         PDF as the output format for .ps or .pdf suffixes.

++

++ - QProcess

++

++       * Added support for channel redirection to allow data to be redirected

++         to files or between processes.

++

++ - QPushButton

++

++       * Ensured that, when a menu is added to a push button, its action is

++         also added to enable keyboard shortcuts.

++

++ - QRect, QRectF, QRegion

++

++       * Renamed unite(), intersect(), subtract(), and eor() to united(),

++         intersected(), subtracted(), and xored() respectively.

++

++       * Added QRegion::intersects(QRegion) and QRegion::intersects(QRect).

++

++       * Fixed case where rect1 & rect2 & rect3 would return a non-empty

++         result for disjoint rectangles.

++

++ - QRegExp

++

++       * Added RegExp2 syntax, providing greedy quantifiers (+, *, etc.).

++

++       * Marks (QChar::isMark()) are now treated as word characters,

++         affecting the behavior of '\b', '\w', and '\W' for languages

++         that use diacritic marks (e.g., Arabic).

++

++       * Fix reentrancy issue with the regexp cache.

++

++ - QScrollArea

++

++       * Added the ensureWidgetVisible() function to facilitate scrolling to

++         specific child widgets in a scroll area.

++

++ - QScrollBar

++

++       * Ensured that a SliderMove action is triggered when the slider value is

++         changed through a wheel event.

++

++ - QSet

++

++       * Added QSet::iterator and QMutableSetIterator.

++

++ - QSettings

++

++       * Store key sequences as readable entries in INI files.

++

++       * Detect NFS to prevent hanging when lockd isn't running.

++

++ - QShortcut

++

++       * Added the setAutoRepeat(bool) function to disable auto-repeating

++         actions on keyboard shortcuts.

++

++ - QSize

++

++       * Fixed potential overflow issue in scale().

++

++ - QSlider

++

++       * Added support for jump-to-here positioning.

++

++ - QSortFilterProxyModel

++

++       * Handle source model changes (e.g., data changes, item insertion

++         and removal) in a fine-grained manner, so that the proxy model

++         behaves more like a "real" model.

++

++       * Added sortRole, filterRole and dynamicSortFilter properties.

++

++       * Perform stable sorting of items.

++

++       * Fixed support for drag and drop operations where one item is dropped

++         on top of another.

++

++       * Ensure that persistent indexes are updated when the layout of the

++         source model changes.

++

++       * Made match() respect the current sorting and filtering settings.

++

++       * Forward mimeTypes() and supportedDropActions() calls to source

++         models.

++

++       * Added the ability to filter on all the columns.

++

++       * Added the filterChanged() function to enable custom filtering to be

++         implemented.

++

++ - QSqlQuery

++

++       * Added execBatch() for executing SQL commands in a batch. Currently

++         only implemented for the Oracle driver.

++

++       * Fixed a case where executedQuery() would not return the executed

++         query.

++

++ - QSqlRelationalTableModel

++

++       * Fixed issue related to sorting a relational column when using the

++         PostgreSQL driver.

++

++

++       * Fixed crash that occurred when removing widgets under certain

++         conditions.

++

++ - QStackedWidget

++

++       * Fixed crash that occurred when removing widgets under certain

++         conditions.

++

++       * Fixed issue where the size hint of the current widget would not be

++         respected.

++

++ - QStandardItemModel

++

++       * Added an item-based API for use with QStandardItem.

++

++       * Reimplemented sort().

++

++       * Added NoToolBarArea to the DockWidgetArea enum.

++         Key_Execute, Key_Sleep, Key_Play and Key_Zoom.

++

++       * Added OpenHandCursor and ClosedHandCursor for use with QCursor.

++

++ - QTabBar

++

++       * QTabBar text can now be elided; this is controlled by the elideMode

++         property.

++

++       * You can now turn on or off the "scroll buttons" for the tab bar with

++         the usesScrollButtons property.

++

++       * Non-pixmap based styles will now fill the background of the tab with

++         the palette's window role.

++

++ - QTabletEvent:

++

++       * Ensured that QTabletEvents are dispatched with the proper relative

++         coordinates.

++

++       * Added proximity as another type of a tablet event (currently only sent

++         to QApplication).

++

++ - QTableView

++

++       * Added API for spanning cells.

++

++       * Ensured that cells are selected when the user right clicks on them.

++

++       * Added a corner widget.

++

++       * Added the setSortingEnabled property.

++

++ - QTableWidget

++

++       * Added the clearContents() function to enable the contents of the view

++         to be cleared while not resetting the headers.

++

++       * QTableWidget now uses stable sorting.

++

++       * Fixed append() to use the current character format.

++

++       * Changed mergeCurrentCharFormat() to behave in the same way as

++         QTextCursor::mergeCharFormat, without applying the format to the

++         word under the cursor.

++

++       * QTextEdit now ensures that the cursor is visible the first time the

++         widget is shown or when replacing the contents entirely with

++         setPlainText() or setHtml().

++

++       * Fixed issue where the setPlainText() discarded the current character

++         to be changed.

++

++ - QThread

++

++       * Related to changes to QObject, currentThread() always returns a

++         valid pointer. (Previous versions of Qt would return zero if called

++         from non-QThread threads; this does not happen in Qt 4.2).

++

++ - QToolBar

++

++       * Introduced various fixes to better support tool buttons, button

++         groups and comboboxes in the toolbar extension menu.

++

++         the valid area for the tooltip. (If you move the cursor outside this

++         area the tooltip will hide.)

++

++       * Added a widget attribute to show tooltips for inactive windows.

++

++ - QTranslator

++

++       * Added support for plural forms through a new QObject::tr() overload.

++

++       * Significantly speed up isRowHidden() for the common case.

++

++       * Improved row painting performance.

++

++       * After expanding, fetchMore() is called on the expanded index giving

++         the model a way to dynamically populate the children.

++

++       * Fixed issue where an item could expand when all children were

++         hidden.

++

++       * Added support for horizontal scrolling using the left/right arrow

++         keys.

++

++       * Added a property to enable the focus rectangle in a tree view to be

++         shown over all columns.

++

++       * Added more key bindings for expanding and collapsing the nodes.

++

++       * Added the expandAll() and collapseAll() slots.

++

++       * Added animations for expanding and collapsing branches.

++

++       * Take all rows into account when computing the size hint for a

++         column.

++

++       * Added the setSortingEnabled property.

++

++       * Fixed the behavior of the scrollbars so that they no longer

++         disappear after removing and re-inserting items while the view is

++         hidden.

++

++       * Fixed memory corruption that could occur when inserting and removing

++         rows.

++

++       * Don't draw branches for hidden rows.

++

++ - QTreeWidget

++

++       * Added the const indexOfTopLevelItem() function.

++

++       * Improved item insertion speed.

++

++       * Fixed crash caused by calling QTreeWidgetItem::setData() with a

++         negative number.

++

++       * QTreeWidget now uses stable sorting.

++

++       * Made construction of single column items a bit more convenient.

++

++       * Added the invisibleRootItem() function.

++

++       * Ensured that the header is repainted immediately when the header

++         data changes.

++

++ - QUiLoader

++

++       * Exposed workingDirectory() and setWorkingDirectory() from

++         QAbstractFormBuilder to assist with run-time form loading.

++

++ - QUrl

++

++       * Added errorString() to improve error reporting.

++       * Added support for all QMetaType types.

++

++       * Added support for QMatrix as a known meta-type.

++

++       * Added support for conversions from QBrush to QColor and QPixmap,

++         and from QColor and QPixmap to QBrush.

++

++       * Added support for conversions between QSize and QSizeF, between

++         QLine and QLineF, from long long to char, and from unsigned long

++         long to char.

++

++       * Added support for conversions from QPointF to QPoint and from QRectF

++         to QRect.

++

++       * Fixed issue where QVariant(Qt::blue) would not create a variant of

++         type QVariant::Color.

++

++       * Added support for conversions from int, unsigned int, long long,

++         unsigned long long, and double to QByteArray.

++

++ - QWhatsThis

++

++ - QWorkspace

++

++       * Resolved issue causing the maximized controls to overlap with the

++         menu in reverse mode.

++

++       * Fixed issue where child windows could grow a few pixels when

++         restoring geometry in certain styles.

++

++       * Ensured that right-to-left layout is respected when positioning new

++         windows.

++

++       * Fixed crash that occurred when a child widget did not have a title

++         bar.

++

++       * Fixed issue where maximized child windows could be clipped at the

++         bottom of the workspace.

++

++ - quintptr and qptrdiff

++

++

++ AIX

++ ---

++

++ - The makeC++SharedLib tool is deprecated; use the "-qmkshrobj" compiler

++   option to generate shared libraries instead.

++

++

++ X11

++ ---

++

++ - Added support to internally detect the current desktop environment.

++

++ - QAbstractItemView

++

++       * Fixed assertion caused by interrupting a drag and drop operation

++         with a modal dialog on X11.

++

++

++ Mac OS X

++ --------

++

++ - Mac OS 10.2 support dropped.

++

++ - QuickDraw support in QPaintEngine dropped; everything folded into the

++   CoreGraphics support.

++

++ - All libraries in Qt are now built as frameworks when -framework mode is

++   selected (default) during the configuration process.

++

++ - Many accessibility improvements, including better VoiceOver support. The

++   following widgets have had their accessibilty updated for this release:

++   QSplitter, QScrollBar, QLabel, QCheckBox, QRadioButton, QTabBar,

++   QTabWidget, QSlider, and QScrollBar.

++

++ - Hidden files are now reported as hidden by QFileInfo, QDirModel, etc.

++

++ - Windows now have a transparent size grips, an attribute for specifying an

++   opaque size grip was added.

++

++ - Metrowerks generator has been removed.

++

++ - Ensured that the anti-aliasing threshold setting is followed.

++

++ - Added a standard "Minimize" menu item to Assistant's Window menu.

++

++ - The documentation now has "Xcode-compatible" links so that it can be added

++   into Xcode's documentation viewer. This needs to be done by the developer

++   as regenerating Xcode's index takes quite a long time

++

++ - QAbstractScrollArea

++

++       * Improved look and feel by aligning the scroll bars with the size

++         grip.

++

++ - QClipboard

++

++       * Data copied to the clipboard now stays available after the

++         application exits.

++

++       * Added support for the Find clipboard buffer.

++

++       * Improved the popup sizing so it's always wide enough to display its

++         contents.

++

++       * Improved the popup placement so it stays on screen and does not

++         overlap the Dock.

++

++       * The minimumSizeHint() and sizeHint() functions now honor

++         minimumContentsLength.

++

++ - QKeyEvent

++

++       * The text() of a QKeyEvent is filled with the control character if

++         the user pressed the real Control key (Meta in Qt) and another key.

++         This brings the behavior of Qt on Mac OS X more in line with Qt on

++         other platforms.

++

++ - QLibrary

++

++       * Removed the dependency on dlcompat for library loading and resolving

++         in favor of native calls. This means that you can unload libraries

++         on Mac OS X 10.4 or later, but not on 10.3 (since that uses dlcompat

++         itself).

++

++ - QMacStyle

++

++       * QMacStyle only uses HITheme for drawing now (no use of Appearance

++         Manager).

++

++       * Fixed placement of text on buttons and group boxes for non-Latin

++         locales.

++

++       * Fixed rendering of small and mini buttons.

++

++       * Attempt to be a bit smarter before changing a push button to bevel

++         button when the size gets too small.

++

++       * Draws the focus ring for line edits when they are near the "top" of

++         the widget hierarchy.

++

++       * Ensured that the tickmarks are drawn correctly.

++

++       * Implemented the standardIconImplementation() function.

++

++       * Fixed the look of line edits.

++

++       * "Colorless" controls now look better.

++

++       * Fixed the sort indicator.

++

++       * Improved the look of text controls, such as QTextEdit, to fit in

++         better with the native style.

++

++ - QMenu

++

++       * Popups no longer show up in Expose.

++

++       * Ensured that the proper PageUp and PageDown behavior are used.

++

++ - QMenuBar

++

++       * Added support for explicit merging of items using QAction::MenuRole.

++

++       * Added support for localization of merged items.

++

++ - QMessageBox

++

++       * A message box that is set to be window modal will automatically

++         become a sheet.

++

++       * Improved the look of the icons used to fit in with the native style.

++

++ - QPainter

++

++       * Fixed off-by-one error when drawing certain primitives.

++

++       * Fixed off-by-many error when drawing certain primitives using a

++         scaling matrix.

++

++       * Fixed clipping so that setting an empty clip will clip away

++         everything.

++

++       * Fixed changing between custom dash patterns.

++

++       * Added combinedMatrix() which contains both world and viewport/window

++         transformations.

++

++       * Added the setOpacity() function.

++

++       * Added MiterJoins that are compliant with SVG miter joins.

++

++ - QPainterPath

++

++       * Added the arcMoveTo() and setElementPosition() functions.

++

++ - QPixmap

++

++       * Added functions to convert to/from a CGImageRef (for CoreGraphics

++         interoperability).

++

++       * Fixed various Qt/Mac masking and alpha transparency issues.

++

++ - QPrinter

++

++       * Made QPrinter objects resuable.

++

++ - QProcess

++

++       * Always use UTF-8 encoding when passing commands.

++

++ - QScrollBar

++

++       * Improved handling of the case where the scrollbar is to short to

++         draw all its controls.

++

++ - QTextEdit

++

++       * Improved the look of the widget to fit in with the native style.

++

++ - QWidget

++

++       * All HIViewRefs inside Qt/Mac are created with the

++         kWindowStandardHandlerAttribute.

++

++       * Added the ability to wrap a native HIViewRef with create().

++

++       * Windows that have parents with the WindowStaysOnTopHint also get the

++         WindowStaysOnTopHint.

++

++

++ Windows

++ -------

++

++ - Ensured that widgets do not show themselves in a hover state if a popup

++   has focus.

++

++ - Fixed issues with rendering system icons on 16 bits-per-pixel displays.

++

++ - Fixed issue where fonts or colors would be reset on the application

++   whenever windows produced a WM_SETTINGSCHANGE event.

++
