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) and Windows
|
||
|
|
(VC++). Qt 3.3 now also officially supports FreeBSD.
|
||
|
|
|
||
|
|
Qt 3.3 also supports precompiled headers for both Windows and Mac OS
|
||
|
|
X. To use precompiled headers when compiling your Qt application
|
||
|
|
simply add PRECOMPH 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.
|
||
|
|
|
||
|
|
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
|
||
|
|
------
|
||
|
|
|
||
|
|
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 is now supported (the
|
||
|
|
parameters are of type int& 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 Linux and FreeBSD. GNU gcc is supported on Windows using
|
||
|
|
MinGW.
|
||
|
|
|
||
|
|
Qt 3.3 no longer officially supports the Sun CC 5.0 compiler or the
|
||
|
|
IRIX MIPSpro o32 mode.

|
|
|
||
|
|
- QHostAddress
|
||
|
|
Added new constructor for IPv6 and new functions
|
||

Keyboard search now uses the sort column as the column to
|
||
|
|
start searching in.
|
||
|
|
Improved branch drawing.
|
||
|
|
|
||
|

|
||
|
|
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.
