This file provides an overview of the main +changes since version 3.0.5. For further details see the online +documentation which is included in this distribution, and also +available at http://qt.nokia.com/doc/. + +The Qt version 3.1 series is binary compatible with the 3.0.x series: +applications compiled for 3.0 will continue to run with 3.1. + + +**************************************************************************** +* General * +**************************************************************************** + +Qt Script for Applications +-------------------------- +Qt 3.1 is the first Qt release that can be used with Qt Script for +Applications (QSA). QSA provides a scripting engine, an IDE for +creating and editing scripts and script forms, and bindings to the Qt +API. Script-enabling a Qt application is not difficult and the IDE +makes it easy for resellers and end-users to write their own scripts. +QSA is due for release after Qt 3.1. + + +Qt Designer +----------- +Qt Designer, the visual GUI builder, has undergone several usability +improvements. A new dialog for creating and editing signals and slots +connections has been created: it is much easier to use and much faster +for setting up multiple connections. The widgets are now presented in +an easy-to-use toolbox rather than in toolbars (although you can still +have the toolbars if you want). The property editor now handles common +properties in multiple widgets simultaneously. By popular demand, +WYSIWYG support for QWidgetStack has been added. Rich text is now +supported with a rich text editor. And the code editor can be used for +ordinary member functions as well as for slots. + + +Qt Assistant +------------ +Qt Assistant, the Qt documentation browser, can now be used with +custom documentation sets. This new functionality combined with the +new QAssistantClient class means that you can use Qt Assistant as a +help browser for your own applications. Qt Assistant has also been +enhanced by the addition of a fast full text search engine. + + +Motif +----- +The general industry-wide move away from Motif is leaving more and +more companies in need of a migration solution. But converting large +legacy applications in one step is often impractical. To minimize +risks and to manage the workload companies often want to port code on +a module by module basis. Qt 3.1 includeds a completely new Motif +module that supports hybrid applications in which Qt code and Motif +code coexist. (This obsoletes the earlier rudimentary Qt Xt/Motif +extension.) + + +ActiveX +------- +With the release of Qt 3.1, customers who use Qt for Microsoft Windows +development can now use Qt with ActiveX. The new ActiveQt module +provides a simple API for COM and ActiveX. The module can be used to +create applications which host ActiveX controls, and also to create +applications that serve ActiveX controls (e.g. Internet Explorer +plugins). + + +Qt/Mac +------ +The introduction of Qt/Mac, a Mac OS X port of Qt, with Qt 3.0 has +proved a great success. This port has undergone many improvements in +Qt 3.1, especially with respect to Appearance Manager, anti-aliased +text and user settings. The Qt OpenGL support is greatly improved, and +uses the hardware-accelerated drivers. + + +Qt/Embedded +----------- +Graphics, mouse and keyboard drivers can now be compiled as plugins. + + +Qt library +---------- +In addition to the new additions and enhancements referred to above, +as with all major Qt releases, Qt 3.1 includes hundreds of +improvements in the existing class library. Here is a brief summary of +the most significant changes: + +- QTextEdit has a new text format: LogText. This is a performance and + memory optimized format especially designed for the fast display of + large amounts of text. The format supports basic highlighting, + including bold and colored text. + +- The new QSyntaxHighlighter class makes it both easy and efficient to + add syntax highlighting capabilities to a QTextEdit. + +- QHttp and QFtp in earlier Qt's were implementations of the + QNetworkProtocol. Both have been extended to stand in their own + right. If you missed some flexibility in the network protocol + abstractions of earlier Qt's, the new QHttp and QFtp classes should + provide the solution. + +- QAccel, used to handle keyboard shortcuts, now gracefully copes with + shortcut clashes. If a clash occurs, a new signal, + activatedAmbiguously(), is emitted. Classes that use QAccel, like + QButton and QPopupMenu, make use of this new functionality. + Futhermore QAccel can now handle multi-key sequences, for example, + Ctrl+X,Ctrl+F. + +- QClipboard has been extended to simplify data exchange between + programs. + +- Thread support: almost all methods in the tools classes have been + made reentrant. QApplication::postEvent() and a few other methods + are now thread-safe if Qt is compiled as a multi-threaded library. + (The documentation now states if a class or function is thread-safe + or reentrant.) + +- A QMutexLocker class has been added to simplify the locking and + unlocking of mutexes. + +- Input methods: A selectionLength() function has been added to + QIMEvent. Japanese compositions are now handled correctly. Support + for AIMM based input methods (those working on non-Asian versions of + Win95/98/Me) has been added. + +- Large File support: Qt's internals have been modified to support + Large Files (> 2GB). QFileDialog will now correctly display and + select Large Files. + +- SQL module: Support for prepared query execution and value binding + has been added. Among other benefits, this makes it possible to + write large BLOBs (> 2 KB) to Oracle databases, and to write Unicode + strings to SQL Server databases. + + +Build process +------------- +The build process has been improved: + +- The configure script does not need QTDIR to be set anymore. + + +**************************************************************************** +* Library * +**************************************************************************** + +New classes +================== + +- QBackInsertIterator +- QEventLoop +- QIconFactory +- QMutexLocker +- QSyntaxHighlighter + + +QAction +------------------ +New functions: + void setVisible( bool ) + bool isVisible() const + + +QCanvas +------------------ +New functions: + void invalidate() + bool isValid() const + + +QColorDialog +------------------ +New functions: + static void setStandardColor( int, QRgb ) + + +QAccel +------------------ +New signals: + void activatedAmbiguously( int id ) + + +QApplication +------------------ +The event loop has been moved to the QEventLoop class, making it +easier to integrate other toolkits with Qt. + +New functions: + QEventLoop *eventLoop() const + void setEventLoop( QEventLoop * ) + QString sessionKey() const + + +QClipboard +------------------ +New functions: + void clear( Mode mode ) + bool supportsSelection() const + bool ownsSelection() const + bool ownsClipboard() const + QString text( Mode mode ) const + QString text( QCString& subtype, Mode mode ) const + void setText( const QString &, Mode mode ) + QMimeSource *data( Mode mode ) const + void setData( QMimeSource*, Mode mode ) + QImage image( Mode mode ) const + QPixmap pixmap( Mode mode ) const + void setImage( const QImage &, Mode mode ) + void setPixmap( const QPixmap &, Mode mode ) + + +QDesktopWidget +------------------ +New functions: + const QRect& screenGeometry( QWidget *widget ) const + const QRect& screenGeometry( const QPoint &point ) const + const QRect& availableGeometry( int screen ) const + const QRect& availableGeometry( QWidget *widget ) const + const QRect& availableGeometry( const QPoint &point ) const + + +QFileDialog +------------------ +Large Files (> 2GB) are now correctly displayed and selected. + + +QFileInfo +------------------ +QFileInfo now supports Large Files (> 2GB) internally.
