Qt 4.5 introduces many new features and improvements as well as bugfixes
over the 4.4.x series. For more details, refer to the online documentation
included in this distribution. The documentation is also available online:
http://qt.nokia.com/doc/4.5
The Qt version 4.5 series is binary compatible with the 4.4.x series.
Applications compiled for 4.4 will continue to run with 4.5.
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
--------------------
New features
------------
- Disk Caching in QtNetwork
* Added support for http caching in QNetworkAccessManager.
* New classes: QAbstractNetworkCache, QNetworkDiskCache.
* QNetworkDiskCache is a simple disk-based cache.
- QDate
* [207690] Added QDate::getDate().
- QDateTimeEdit
* [196924] Improved QDateTimeEdit's usability. It now skips ahead to the
next field when input can't be valid for the current section.
- QDateTime
* [178738] Fixed QDateTime::secsTo() to return the correct value.
- QDBusPendingCall / QDBusPendingCallWatcher / QDBusPendingReply
* New classes to make calls whose replies can be received later.
- QDesktopServices
* Added the ability to determine the proper location to store cache files.
- QGraphicsItem
* Added the QGraphicsItem::itemTransform() function.
* [209357] Added the QGraphicsItem::opacity() function.
* [209978] Added the QGraphicsItem::ItemStacksBehindParent flag to allow
children to be stacked behind their parent item.
* Added QGraphicsItem::mapRect() functions.
- QGraphicsScene
* Added the QGraphicsScene::sortCacheEnabled property.
* Added the QGraphicsScene::stickyFocus property.
- QGraphicsTextItem
* [242331] Added the QGraphicsTextItem::tabChangesFocus() function.
- QGraphicsView
* [210121] Added action, shortcut and shortcut override support to
QGraphicsView and QGraphicsItem.
- QLineEdit
* Added the ability to set the text margin size.
- QMainWindow
* Added API to detect which dock widget is tabified together with another
dock widget.
- QMessageBox
* It is now possible to create categories in QErrorMessage to avoid error
messages from the same category popping up repeatedly.
- QMetaObject
* Added introspection of constructors, including the ability to invoke a
constructor.
- QMetaProperty
* [217531] Added the notifySignalIndex() function, which can be used to
introspect which signal (if any) is emitted when a property is changed.
- QNetworkCookie
* [206125] Added support for HTTP-only cookies.
- QNetworkProxyFactory
* Added support for a factory of QNetworkProxy whose result can
change depending on the connection being attempted.
* Added support for querying system proxy settings on Mac OS X and
Windows.
- QSharedPointer / QWeakPointer
* Added two new classes for sharing pointers with support for atomic
reference counting and custom destructors.
- QStringRef
* [191369] Added QStringRef::localeAwareCompare() functions.
- QTabBar
* Added the ability to place close buttons and widgets on tabs.
* Added the ability to choose the selection behavior after a tab is
removed.
* Added a document mode which, on Mac OS X, paints the widget like
Safari's tabs.
* Added the movable property so that the user can move tabs easily.
* Added mouse wheel support so that the mouse wheel can be used to change
tabs.
- QTabWidget
* Added a document mode that removes the tab widget border.
- QTcpSocket
* [183743] Added support for requesting connections via proxies by
hostname (no DNS resolution made on the client machine).
- QTextDocument / QTextDocumentWriter
* Added the QTextDocumentWriter class which allows exporting of
QTextDocument text and images to the OpenDocument format
(ISO/IEC 26300).
- QtScriptTools
* Added a new module to provide a debugger for Qt Script.
- Qt::WA_TranslucentBackground
* Added this new window attribute to be able to have per-pixel
translucency for top-level windows.
- Qt::WindowCloseButtonHint
* Added a new window hint to control the visibility of the window close
button.
- Qt::WindowStaysOnBottomHint
* Added a new window hint to allow the window to stay below all other
windows.
- Q_SIGNAL and Q_SLOT
* Added new keywords to allow a single function to be marked as a signal
or slot.
- QT4_IM_MODULE
* [227849] Added a new environment variable that specifies the input
method module to use and takes precedence over the QT_IM_MODULE
enviroment variable. This environment variable allows the user to
configure the environment to use different input methods for Qt 3 and
Qt 4-based applications.
- QXmlQuery
* Added a number of overloads to the bindVariable(), setFocus(), and
evaluateTo() functions.
* Added a property for controlling the network access manager.
* Partial support for XSL-T has been added. See the main documentation for
the QtXmlPatterns module for details.
Optimizations
-------------
- The backing store has been re-factored and optimized
* Significant improvement in overall performance of painting for widgets.
* Reduced the number of QRegion operations.
* Improved update handling.
* Improved the performance of clipping.
* Support for full static contents.
- QGraphicsView has been optimized in several areas
* Reduced the number of floating point operations.
* Improved update handling.
* Improved handling of deeply nested item trees.
* Improved the performance of clipping for ItemClipChildrenToShape.
* Improved sorting speed, so scenes with deeply nested item hierarchies do
not affect the performance as compared to Qt 4.4.
- Widget style sheets optimisations
* Improved the speed of style sheet initialization.
- QAbstractItemModel
* Optimized QPersistantModelIndex creation and deletion.
* Optimized adding and removing rows and columns.
- QFileSystemModel
* Ensured that the model is always sorted when required.
- QTreeView
* Optimized expanding and collapsing items.
* Optimized expanding animations with large views.
- QRect and QRectF
* Improves on functions like intersect(), contains(), etc.
- QTransform
* Reduced the number of multiplications used for simple matrix types.
- QRasterPaintEngine
* Reduced overhead of state changes; e.g., setPen() and setBrush().
* Introduced a cache scheme for Windows glyphs, thus improving text
drawing performance significantly.
* Reduced the cost of doing rectangular clipping.
* Improved pixmap drawing.
* Improved pixmap scaling.
* Optimized drawing of anti-aliased lines.
* Optimized drawing of anti-aliased dashed lines.
Third party components

****************************************************************************
* Library *
****************************************************************************
- General Fixes
* [217988] Fixed a thread safety issue in QFontPrivate::engineForScript
which could lead to buggy text rendering when rendering text from
several threads.
* [233703] Fixed a crash that occured when the input method (for example
SCIM) was destroyed while the application is still running.
* [233634] When there are several input method plugins available, they are
now initialized only when the user switches to them.
* [231089] Fixed an issue which caused HTTP GET to fail for chunk
transfers.
* [193475] Consumer tablet devices (like Wacom Graphite and Bamboo) now
work on Windows and Mac OS X.

for Qt Jambi.

ends on the viewport.

selection on the viewport.
