| Qt 3.3 introduces many new features as well as many improvements over |
| the 3.2.x series. For more details, see the online documentation which |
| is included in this distribution. The documentation is also available |
| at http://qt.nokia.com/doc/ |
| |
| The Qt version 3.3 series is binary compatible with the 3.2.x series. |
| Applications compiled for 3.2 will continue to run with 3.3. |

| |
| Qt library |
| ---------- |
| |
| Qt 3.3 is .NET enabled. This release shows how to use classes |
| developed with Qt in a .NET environment. It includes an analysis of |
| the different interoperability infrastructures provided by the .NET |
| framework. An example demonstrates how to use both a manual approach |
| with Microsoft's managed extensions to the C++ language, and also |
| automated solutions based on COM and the ActiveQt framework to reuse |
| native Qt classes and widgets in .NET projects. To learn more about Qt |
| and .NET read the "Using Qt objects in Microsoft .NET" walkthrough |
| found in the ActiveQt framework documentation. |
| |
| Qt 3.3 now supports IPv6 in addition to IPv4. New functions have been |
| added for IPv6 support to QSocketDevice, QHostAddress and QDNns. |
| |
| Qt now includes a new tool class called QLocale. This class converts |
| between numbers and their string representations in various languages. |
| QLocale supports the concept of a default locale which allows a locale |
| to be set globally for the entire application. |
| |
| Support for new 64bit platforms and compilers has been added for Qt |
| 3.3. Qt now supports Itanium on both Linux (Intel C++ compiler) and |
| Windows (MSVC and Intel C++ Compiler). Qt 3.3 now also officially |
| supports FreeBSD. |
| |
| Qt 3.3 also supports precompiled headers for Windows, Mac OS X and |
| X11. To use precompiled headers when compiling your Qt application |
| simply add PRECOMPILED_HEADER and then specify the header file to |
| precompile in your .pro file. To learn more about precompiled headers |
| see the "Using Precompiled Headers" chapter in the qmake User Guide. |
| |
| Two new database drivers have been added to the SQL module, InterBase |
| and SQLite. This makes it possible to write database applications that |
| do not require a database server. SQLite is provided in the Qt 3.3 |
| distribution and can be enabled with either -qt-sql-sqlite or |
| -plugin-sql-sqlite. The InterBase plugin also works with Firebird, the |
| open source version of InterBase. |
| |
| QWidget has a new function setWindowState() which is used to make a |
| widget maximized, minimized, etc. This allows individual settings for |
| the minimized/maximized/fullscreen properties. |
| |
| Support for semi-transparent top-level widgets on Mac OS X and Windows |
| 2000/XP has also been added. |
| |
| A new example, qregexptester, has been added that makes it easy to |
| test QRegExps on sample strings. |
| |
| Qt 3.3 includes in addition to this, numerous bug fixes and |
| improvements. Special thanks goes to KDE for their reports and |
| suggestions. |
| |
| |
| Qt/Embedded |
| ----------- |
| |
| Added support for SNAP graphics drivers from SciTech Software. This |
| gives access to accelerated drivers for more than 150 graphics |
| chipsets. |
| |
| |
| Qt/Mac |
| ------ |
| |
| QAccessible support has been introduced (implemented in terms of Apple's |
| Universal Access API). |
| |
| Added support for Xcode project files in qmake. |
| |
| Added Tablet support for Mac OS X. |
| |
| Numerous visual improvements. |
| |
| |
| Qt/X11 |
| ------ |
| |
| Added support for Xft2 client side fonts on X servers without the |
| RENDER extension. |
| |
| Added a new configure option (-dlopen-opengl) which will remove the |
| OpenGL and Xmu library dependencies in the Qt library. The functions |
| used by Qt in those libraries are resolved manually using dlopen() |
| when this option is used. |
| |
| Improved support for the Extended Window Manager Hints. |
| |
| |
| Qt/Windows |
| ---------- |
| |
| Added support for Windows Server 2003 (Win64/Itanium). |
| |
| |
| Qt Motif Extension |
| ------------------ |
| |
| Clipboard operations now work between Qt and Motif widgets in the same |
| application. Click-to-focus works with Motif widgets that are children |
| of a QMotifWidget. |
| |
| |
| ActiveQt Extension |
| ------------------ |
| |
| Two new functions, QAxFactory::startServer() and |
| QAxFactory::stopServer(), can be used to start and stop an |
| out-of-process ActiveQt server at runtime. The new functions |
| QAxFactory::serverDirPath() and QAxFactory::serverFilePath() return |
| the location of the COM server binary. Server binaries no longer |
| need to implement a main() entry point function. A default |
| implementation is used for out-of-process servers. IClassFactory2 |
| is supported for the development of licensed components, and |
| QAxFactory supports the creation of non-visual COM objects. Class |
| specific information can be provided directly in the C++ class |
| declaration using the Q_CLASSINFO macro to control how objects and |
| controls are registered and exposed. New helper classes and macros |
| are avialable to make it even easier to expose object classes (see the |
| QAxServer documentation for details). |
| |
| COM objects developed with ActiveQt are now supported in a wider range |
| of clients, including Microsoft Office applications and .NET. Examples |
| that demonstrate how to use the Qt objects from the examples in .NET |
| languages like C# are included. QStringList is supported as a type, |
| and QRect, QSize and QPoint are now supported datatypes for control |
| properties and as reference parameters. Saving the controls to a |
| storage or stream now includes the version number of the QDataStream |
| used for the serialization (note that this might break existing |
| storages). |
| |
| The QAxContainer library is now static even for shared configurations |
| of Qt. This simplifies deployment and allows using both QAxServer and |
| QAxContainer in one project, i.e. an OLE automatable application that |
| uses COM objects itself. The semantics of QAxBase::setControl() have |
| been extended to allow creating of COM objects on remote machines via |
| DCOM, to create controls requiring a license key and to connect to |
| already running objects. The implementation of QAxBase::dynamicCall() |
| has been improved to support passing of parameter values directly in |
| the function string. Three new classes, QAxScript, QAxScriptManager |
| and QAxScriptEngine, can be used to script COM objects from within Qt |
| applications using Windows Script Host. |
| |
| SAFEARRAY(BSTR) parameters are supported as QStringList. Calling COM |
| object methods with out-parameters of type short, char and float is |
| now supported (the parameters are of type int& and double& in the Qt |
| wrapper), and QVariants used for out-parameters don't have to be |
| initialized to the expected type. Calling QByteArray functions in |
| out-of-process controls no longer returns an error code. The control's |
| client side is set to zero when the container releases the control. |
| |
| |
| Qt Designer |
| ----------- |
| |
| Qt Designer, Qt's visual GUI builder, has received some speed |
| optimizations, along with minor improvements to the menu editor. |
| |
| |
| Qt Assistant |
| ------------ |
| |
| Qt Assistant now saves the states of the tab bars between runs. This |
| enables users to start browsing where they ended their previous |
| assistant session. |
| |
| Shortcuts for Find Next (F3) and Find Previous (Shift+F3) have been |
| implemented. |
| |
| |
| Compilers |
| --------- |
| |
| Qt 3.3 adds support for two new compilers. The Intel C++ compiler is |
| supported on Windows, Linux and FreeBSD. GNU gcc is supported on |
| Windows using MinGW. |
| |
| Qt 3.3 no longer officially supports the Sun WorkShop 5.0 compiler or the |
| SGI MIPSpro o32 mode. |
| |
| |

| Unicode character of type ushort, %ls takes a zero-terminated |
| array of Unicode characters of type ushort (i.e. const |
| ushort*). Also added support for precision (e.g. "%.5s"). |
| Changed arg() to support "%L1" for localized conversions. |
| Windows only: QString::local8Bit() now returns an empty |
| QCString when called on a null QString to unify behavior |
| with the other platforms. |
| |
| - QStyle |
| Add a new primitive element: PE_RubberBand. |
| Added PM_MenuBarItemSpacing and PM_ToolBarItemSpacing pixel metrics. |
| |
| - QTextDrag |

| Comparison between variants where one of the variants is a |
| numeric value will compare on the numeric value. Type casting |
| between different variants is more consistent. |
| |
| - QWidget |
| Added setWindowOpacity() and windowOpacity() to support |
| transparent top-level widgets on Windows and Mac. |
| Added windowState() and setWindowState() to allow individual |
| setting of the minimized/maximized/fullscreen properties. |
| |
| - QWindowsStyle |
| Qt supports toggling of the accelerator underlines using the |
| Alt-key on Windows 98, 2000 and later. On other platforms this |
| change has no effect. |
