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.+
−
+
