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 4.2 series is binary compatible with the 4.1.x series. +Applications compiled for 4.1 will continue to run with 4.2. + +The Qtopia Core version 4.2 series is binary compatible with the 4.1.x +series except for some parts of the device handling API, as detailed +in Platform Specific Changes below. + + +**************************************************************************** +* General * +**************************************************************************** + + +New features +------------ + +- QCalendarWidget provides a standard monthly calendar widget with date + selection features. + +- QCleanlooksStyle provides the new Cleanlooks style, a clone of the GNOME + ClearLooks style, giving Qt applications a native look on GNOME desktops. + +- QCompleter provides facilities for auto completion in text entry widgets. + +- QDataWidgetMapper can be used to make widgets data-aware by mapping them + to sections of an item model. + +- QDesktopServices provides desktop integration features, such as support + for opening URLs using system services. + +- QDialogButtonBox is used in dialogs to ensure that buttons are placed + according to platform-specific style guidelines. + +- QFileSystemWatcher enables applications to monitor files and directories + for changes. + +- QFontComboBox provides a standard font selection widget for document + processing applications. + +- QGraphicsView and related classes provide the Graphics View framework, a + replacement for Qt 3's canvas module that provides an improved API, enhanced + rendering, and more responsive handling of large numbers of canvas items. + +- QGLFramebufferObject encapsulates OpenGL framebuffer objects. + +- QMacPasteboardMime handles Pasteboard access on Qt/Mac. This obsoletes + QMacMime as the underlying system has changed to support Apple's new + Pasteboard Manager. Any old QMacMime objects will not be used. + +- QNetworkInterface represents a network interface, providing information + about the host's IP addresses and network interfaces. + +- QResource provides static functions that control resource lookup and + provides a way to navigate resources directly without levels of + indirection through QFile/QFileEngine. + +- QSystemTrayIcon allows applications to provide their own icon in the + system tray. + +- QTimeLine gives developers access to a standard time line class with which + to create widget animations. + +- The QtDBus module provides inter-process communication on platforms + that support the D-BUS protocol. + +- The QUndo* classes in Qt's Undo framework provide undo/redo functionality + for applications. + +- Support for the Glib event loop to enable integration between Qt and non-Qt + applications on the GNOME desktop environment. + +- Improved Accessibility for item-based views and QTextEdit. + +- Support for main window animations and tabbed dock widgets. + +- Added an SVG icon engine to enable SVG drawings to be used by QIcon. + +- Widgets can now be styled according to rules specified in a style sheet, + using a syntax familiar to users of Cascading Style Sheets (CSS). Style + sheets are set using the QWidget::styleSheet property. + +- Introduced a new key mapper system which improves the shortcut system by + only testing the real possible shortcuts, such as Ctrl+Shift+= and Ctrl++ + on an English keyboard. + +- Improved and enhanced QMessageBox to support native look and feel on many + common platforms. + +- Experimental support for Qt usage reporting ("metered licenses") on Linux, + Windows and Mac OS X. Reporting is disabled by default. + +- A screen magnification utility, pixeltool, is provided. It is designed to help + with the process of fine-tuning styles and user interface features. + +- New qrand() and qsrand() functions to provide thread safe equivalents to + rand() and srand(). + + +General improvements +-------------------- + +- Item views + + * Selections are maintained when the layout of the model changes + (e.g., due to sorting). + + * Convenience views can perform dynamic sorting of items when the data + in items changes. + + * QStandardItem provides an item-based API for use with + QStandardItemModel and the model/view item view classes. + + * QStandardItemModel API provides a classic item-based approach to + working with models. + + * Single selection item views on Mac OS X cannot change their current + item without changing the current selection when using keyboard + navigation. + +- Plastique style has improved support for palettes, and now requires + XRender support on X11 for alpha transparency. + +- Tulip containers + + * Added typedefs for STL compatability. + + * Added function overloads to make the API easier to use. + +- Added the Q3TextStream class for compatiblity with Qt 3 and to assist with + porting projects. + +- OpenGL paint engine + + * Added support for all composition modes of QPainter natively using + OpenGL. + + * Fixed a case where very large polygons failed to render correctly. + + * Ensured that glClear() is only called in begin() if the + QGLWidget::autoFillBackground() property is true. + + * Ensured that a buffer swap is only performed in end() if + QGLWidget::autoBufferSwap() is true. + + * Improved text drawing speed and quality. + +- Raster paint engine + + * Fixed blending of 8 bit indexed images with alpha values. + + * Fixed drawing onto QImages that were wider than 2048 pixels. + + * Fixed alpha-blending and anti-aliasing on ARGB32 images. + + * Improved point drawing performance. + + * Fixed issue where lines were drawn between coordinates that were + rounded instead of truncated. + + * Ensured that setClipRegion(QRegion()) clips away all painting + operations as originally intended. + + +Third party components +---------------------- + +- Dropped support for MySQL version 3. + +- Updated Qt's SQLite version to 3.3.6. + +- Updated Qt's FreeType version to 2.2.1. + +- Updated Qt's libpng version to 1.2.10. + + +Build System +------------ + +- Auto-detect PostgreSQL and MySQL using pg_config and mysql_config on UNIX + based systems in the configure script + +- Added "-system-sqlite" option to configure to use the system's SQLite + library instead of Qt's SQLite version. + +- Added QT_ASCII_CAST_WARNINGS define that will output a warning on implicit + ascii to Unicode conversion when set. Only works if the compiler supports + deprecated API warnings. + +- Added Q_REQUIRED_RESULT to some functions. This macro triggers a warning + if the result of a function is discarded. Currently only supported by gcc. + + +- Qt/X11, Qt/Mac and Qtopia Core only: + + * Added all QT_NO_* defines to the build key. + + +- Qt/X11 and Qtopia Core only: + + * As in Qt 3, the configure script enables the -release option by + default, causing the Qt libraries to be built with optimizations. If + configured with the -debug option, the debug builds no longer result + in libraries with the _debug suffix. + + On modern systems, flags are added to the Qt build to also + generate debugging information, which is then stored in a + separate .debug file. The additional debug information does not + affect the performance of the optimized code and tools like gdb + and valgrind automatically pick up the separate .debug + files. This way it is possible to get useful backtraces even + with release builds of Qt. + + * Removed the last vestiges of the module options in the configure + script, previously they were available but did not function. + + * Implemented a -build option in the configure script to conditionally + compile only certain sections of Qt. + + * Made it possible to build Qt while having "xcode" set as your + QMAKESPEC on OSX. + + +- Windows only: + + * Populated the build key, as done on all the other platforms. + + * Fixed dependency generation in Visual Studio Solutions (.sln) + created by qmake. + + * Added missing platforms to the Visual Studio project generator (X64, + SH3DSP and EBC). + + * Made UIC3 use a temporary file for long command lines. + + * Removed the object file (.o) conflicts with MinGW that appeared when + embedding a native resource file which was named the same as a normal + source file. + + * Fixed mkspec detection when generating project files outside of QTDIR. + + * Removed compiler warnings with MinGW g++ 3.4.5. + + + +**************************************************************************** +* Library * +**************************************************************************** + + +- QAbstractButton + + * Returns QPalette::Button and QPalette::ButtonText for + backgroundRole() and foregroundRole(), respectively, rather than + QPalette::Background and QPalette::Foreground. + + * Ensured that nextCheckState() is called only when there is a state + change. + +- QAbstractItemModel + + * When dropping rows only insert rows that were actually dropped, not + the continuous row count from first to last. + + * Added a supportedDragActions property to be used by + QAbstractItemView when starting a drag. + + * When updating changed persistent indexes, ignore those that haven't + actually changed. + + * Fixed endian issue with createIndex(). + + * Added FixedString matching for match(). + + * Changed the sorting algorithm to use a stable sort. + + * Added persistentIndexList() function. + +- QAbstractItemView + + * Added possibility to copy elements to clipboard on read-only views. + + * Improved handling of QAbstractItemModel::supportedDropActions(). + + * Ensured that the current item is selected when using keyboard + search. + + * Ensured that the view starts with a valid current index. + + * Ensured that data is only committed in currentChanged() if the + editor is not persistent. + + * Fixed crash that occurred when a modal dialogs was opened when + closing an editor. + + * Added verticalScrollMode and horizontalScrollMode properties. + + * Added setItemDelegateForRow() and setItemDelegateForColumn(). + + * Ensured that existing models are disconnected properly when + replaced. + + * Ensured that the doubleClicked() signal is only emitted when the + left button has been double-clicked. + + * Changed setSelection(...) to work when given a non-normalized + rectangle. + + * Fixed regression for shift-selections in ExtendedSelection for + all views. + + * Added dragDropMode property and implemented move support in all of + the views and models. + + * For edit triggers SelectedClicked and DoubleClicked, only trigger + editing when the left button is clicked. + + * Trigger SelectedClicked editing on mouse release, not mouse press. + + * Suppressed the doubleClicked() signal in cases where the clicks + happened on two different items. + + * Enabled keyboard search to be programmatically reset by calling + keyboardSearch() with an empty string as argument. + + * Don't allow drops on items that don't have the Qt::ItemIsDropEnabled + flag set. + + * Added modelAboutToBeReset() and layoutAboutToBeChanged() signals. + + * Suppressed assertion in dropMimeData() for cases where mimeTypes() + returns an empty list. + + * Ensured consistent behavior of drag and drop when rootIndex() is a + valid model index. + + * Made it possible to check a checkbox with only a single click when + using the CurrentChanged edit trigger. + + * Ensured that WhatsThis events are propagated when the relevant item + doesn't have a valid "What's This?" value. + + * Added PositionAtCenter scrollHint. + + * Added support to allow items to be checked and unchecked using the + keyboard. + + * Added support for keypad navigation. + +-

+- QBrush + + * Added a constructor that accepts a QImage. + +- QButtonGroup + + * Added pressed() and released() signals. + + * Fixed a bug caused by removing buttons from button groups. Removed the + internal mapping as well. + + * Ensured that checkedButton() returns the correct value with + non-exclusive groups. + +- QClipboard + + * Added support for find text buffer. + +- QColor + + * Fixed corruption in setRed(), setGreen() and setBlue() for HSV/CMYK + colors. + +- QComboBox + + * Fixed drawing issues related to certain FocusPolicy values. + + * Ensured that the ItemFlags of
