For more details, see the online documentation which +is included in this distribution. The documentation is also available +at http://doc.trolltech.com/ + +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. + +**************************************************************************** +* General * +**************************************************************************** + +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. + + +**************************************************************************** +* Library * +**************************************************************************** + +- QAction + Added a setDisabled() slot similar to QWidget::setDisabled. + Added an activate() slot which activates the action and + executes all connected slots. + QActions::menuText() escapes ampersand characters ('&') when + using the value of the text property. + +- QButtonGroup + Added QButtonGroup::selectedId property to allow mapping with + SQL property sets. + +- QCursor + Added new enum value Qt::BusyCursor. + X11 only: Added QCursor constructor taking a X11 cursor handle. + +- QDom + The QDom classes are now reentrant. + +- QEvent + Added new event type WindowStateChange, obsoleting ShowNormal, + ShowMinimized, ShowMaximized and ShowFullScreen. + +- QHeader + The sizeChange() signal is emitted when the section sizes are + adjusted by double clicking. + +- QHostAddress + Added new constructor for IPv6 and new functions + isIPv6Address() and toIPv6Address(). Obsoleted the functions + isIp4Addr() and ip4Addr(), replacing them with isIPv4Address() + and toIPv4Address(). + +- QIconView + Improved keyboard search to behave like QListView. + +- QListView + Improved alignment for text in QListViewItems. Right aligned + text now has the ellipsis on the left. + Keyboard search now uses the sort column as the column to + start searching in. + Improved branch drawing. + +- QLocale [new] + This new tool class converts between numbers and their string + representations in various languages. + +- QMacStyle + Allow disabling of size constraints. + +- QMovie + Added JNG support. + +- QPixmap + Support full alpha-maps for paletted (8-bit) images. + Support 16-bit grayscale PNG images with transparency. + +- QPushButton + A push button with both an iconset and text left-aligns the + text. + +- QSocketDevice + Added setProtocol() and protocol() for IPv6 support. + +- QSound + Windows: Support loop related APIs. + +- QSplashScreen + Less intrusive stay-on-top policy. + +- QSql + Support for InterBase and SQLite. + +- QStatusBar + Draw messages with the foreground() color of the palette, + rather than with the text() color. + +- QString + Added support for %lc and %ls to sprintf(). %lc takes a + 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 + decode() now autodetects the encoding of text/html content. + +- QTextEdit + Reduced memory consumption by 20 bytes per line. + Added a getter for the currently set QSyntaxHighlighter. + +- QTextBrowser + Qt now automatically detects the charset of HTML files set + with setSource(). + +- QVariant + 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. |
