Qt 4.2 introduces many new features as well as many improvements and
|
||
|
bugfixes over the 4.1.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 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.

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.

|
||
|
whenever possible when errors occur.

|
|
||
|

|
||
|
|
||
|
- QGLWidget
|
||
|
|
||
|
* Fixed a resource leak that could occur when binding QImages with the
|
||
|
bindTexture() function.
|
||
|
|
||
|
* Fixed renderText() to produce proper output when depth buffering is
|
||
|
enabled.
|
||
|
|
||
|
* Fixed bindTexture() to respect premultiplied QImage formats.
|
||
|
|
||
|
* Ensured that the updatesEnabled property is respected.
|
||
|

|
even though the result is documented to be undefined.
|
||
|
|
||
|
* Fixed maximum size handling when adding spacing.
|
||
|
|
||

||
|
|
||
|
* Added the clicked() signal
|
||
|
|
||
|
- QHash
|
||
|
|
||
|
* Prevent conversion of iterator or const_iterator to bool
|
||
|
(e.g., if (map->find(value))) because the conversion always returned
|
||
|
true. Qt 4.1 code that doesn't compile because of this change was most
|
||
|
probably buggy.
|
||
|
|
||
|
* Added the uniqueKeys() function.
|
||
|
|
||
|
- QHeaderView

|
||
|
|
||
|
* Added the swapSections() convenience function.
|
||
|
|
||
|
* Added a more "splitter-like" resize mode.
|
||
|
|
||
|
* Added the possibility for the user to turn off stretch mode by
|
||
|
resizing the header section. This includes the stretchLastSection
|
||
|
property.
|
||
|
|
||
|
* Added the minimumSectionSize property.
|
||
|
|
||
|
* Get the section size hint from the Qt::SizeHintRole, if set.
|
||
|
|
||
|
* Added the ResizeToContents resize mode.

|
||
|

|
||
|
requested size.
|
||
|
|
||
|
* Fixed improper pixmap caching
|
||
|
|
||
|
* Added QDataStream operators for QIcon.
|
||
|
|
||
|
* Added the Selected mode.
|
||
|
|
||
|
- QImage
|
||
|
|
||
|

|
||
|
|
||
|

|
||
|
|

|
||
|
degrees.
|
||
|
|
||
|

|
||
|
|
||
|
* Improved algorithm for smooth scaling to produce better results.
|
||
|
|
||
|
- QImageReader
|
||
|
|
||
|
* Ensured that size() returns an invalid QSize if the image I/O handler
|
||
|
does not support the QImageIOHandler::Size extension.
|
||
|
|
||
|
* Added support for reading negative BMP images.
|
||
|
|
||
|
* Improved handling of invalid devices.
|
||
|
|
||
|
* Added optimizations to ensure that the most likely formats and plugins
|
||
|
are tested first when reading unknown image formats.
|
||
|
|
||
|
* Improved reading of BMP images from sequential QIODevices.
|
||
|
|
||
|
* Support for scaledSize() with JPEG images.
|
||
|
|
||
|
* It is now possible to query the supported options of an image by
|
||
|
calling supportedOptions().
|
||
|
|
||
|
* Stability fixes for the built-in XBM reader.
|
||
|
|
||
|
- QImageWriter
|
||
|
|
||
|
* Ensured that an error is reported when attempting to write an image
|
||
|
to a non-writable device.
|
||
|
|
||
|
* It is now possible to query the supported options of an image by
|
||
|
calling supportedOptions().
|
||
|
|
||
|
- QIODevice
|
||
|
|
||
|
* Fixed a casting bug in QIODevice::getChar().
|
||
|
|
||
|
* Improved reading performance significantly by using an internal buffer
|
||
|
when a device is opened in buffered mode.
|
||
|
|
||
|
* Some behavioral differences have been introduced:
|
||
|
|
||
|
+ The following functions now need to call the base implementation
|
||
|
when reimplemented: atEnd(), bytesAvailable(), size(), canReadLine().
|
||
|
|
||
|
+ pos() should return the base implementation directly.
|
||
|
|
||
|
+ QIODevice now handles the device position internally. seek() should
|
||
|
always end up calling the base implementation.
|
||
|
|
||
|
- QItemDelegate
|
||
|
|
||
|
* Use a widget's USER property to set and get the editor data.
|
||
|
|
||
|
* Removed unnecessary assertions.
|
||
|
|
||
|
* Added the clipping property to enable clipping when painting.
|
||
|
|
||
|
* When the model specifies a font, resolve the font over the existing
|
||
|
one rather than replacing it.
|
||
|
|
||
|
* Fixed issue with rendering of selected pixmaps.
|
||
|
|
||
|
* Ensured that QItemEditorFactory is called with the variant's
|
||
|
userType() so that the factory can distinguish between multiple user
|
||
|
types.
|
||
|
|
||
|
* Ensured that Key_Enter is propagated to the editor before data is
|
||
|
committed, so that the editor has a chance to perform custom input
|
||
|
validation/fixup.
|
||
|
|
||
|
* Let the line edit grow to accomodate long strings.
|
||
|
|
||
|
* Made it easer to subclass the item delegate.
|
||
|
|
||
|
* Added support for keypad navigation.
|
||
|
|
||
|
- QItemSelectionModel
|
||
|
|
||
|
* Improved overall speed, particularly when isSelected() is used.
|
||
|
|
||
|
* Added functions for getting the selected rows or columns.
|
||
|
|
||
|
* Ensured that the current index is updated when it is being removed.
|
||
|
|
||
|
* Ensure that QAbstractItemView::clearSelection() only clears the
|
||
|
selection and not the current index.
|
||
|
|
||
|
* Added the hasSelection() function.
|
||
|
|
||
|
* Fixed some connection leaks (connections were not disconnected) when
|
||
|
an QItemSelectionModel was deleted. This should also speed up some
|
||
|
special cases.
|
||
|
|
||
|
- QKeySequence
|
||
|
|
||
|
* Added a set of platform-dependent standard shortcuts.
|
||
|
|
||
|
* Fixed incorrect parsing of translated modifiers.
|
||
|
|
||
|

|
||
|
|
||
|
* Added support for text selection and hyperlinks.
|
||
|
|
||
|
* Improved handling of scaled pixmaps.
|
||
|
|
||
|
* Made handling of QMovie safer to avoid object ownership issues.
|
||
|
|
||
|
- QLibrary
|
||
|
|
||
|
* Added support for hints to control how libraries are opened on UNIX
|
||
|
systems.
|
||
|
|
||
|
* Added errorString() to report the causes of errors when libraries
|
||
|
fail to load.
|
||
|
|
||
|
* Added easier way to debug plugin loading: Setting QT_DEBUG_PLUGINS=1
|
||
|
in the environment will enable debug message printing on the
|
||
|
console.
|
||
|
|
||
|
* Increased the number of acceptable file name suffixes used to
|
||
|
recognize library files.
|
||
|
|
||
|
- QLineEdit
|
||
|
|
||
|
* Ensured that the Unicode context menu gets shown if language
|
||
|
extensions are present.
|
||
|
|
||
|
* Ensured that editingFinished() is not emitted if a validator is set
|
||
|
and the text cannot be validated.
|
||
|
|
||
|
* Ctrl+A now triggers select all on all platforms.
|
||
|
|
||
|
* Call fixup on focusOut() if !hasAcceptableInput().
|
||
|
|
||
|
* Added auto-completion support with the setCompleter() function.
|
||
|
|
||
|
* Fixed painting errors when contents margins were set.
|
||
|
|
||
|
* Invalid text set using setText() can now be edited where previously
|
||
|
it had to be deleted before new text could be inserted.
|
||
|
|
||
|
* Use SE_LineEditContents to control the contents rect of each
|
||
|
QLineEdit.
|
||
|
|
||
|
- QListView
|
||
|
|
||
|
* Added the batchSize property.
|
||
|
|
||
|
* Don't un-hide currently hidden rows when new rows are inserted.
|
||
|
|
||
|
* Fixed partial repainting bug that occurred when alternatingRowColors
|
||
|
was enabled.
|
||
|
|
||
|
* Ensured that the resize mode is not reset in setViewMode() if it was
|
||
|
already set.
|
||
|
|
||
|
* Fixed crash that occurred when the first item was hidden and
|
||
|
uniformItemSizes was set.
|
||
|
|
||
|
* Added the wordWrap property for wrapping item text.
|
||
|
|
||
|
* Allow the user to select items consecutively when shift-selecting.
|
||
|
|
||
|
* Ensured that only the top item is selected when the user clicks on
|
||
|
an area with several items are stacked on top of each other.
|
||
|
|
||
|
* Optimized hiding and showing of items.
|
||
|
|
||
|
* Fixed issue where dragging an item in Snap mode did not respect the
|
||
|
scroll bar offsets.
|
||
|
|
||
|
* Fixed issue in Snap mode where a (drag and) drop did not always
|
||
|
query the item that existed in the corresponding cell for an enabled
|
||
|
Qt::ItemIsDropEnabled flag.
|
||
|
|
||
|
- QListWidget/QTreeWidget/QTableWidget
|
||
|
|
||
|
* Ensured the dataChanged() signal is emitted when flags are set on an
|
||
|
item.
|
||
|
|
||
|
* Removed unnecessary assertions.
|
||
|
|
||
|
* Added more convenience functions in QListWidget, QTableWidget and
|
||
|
QTreeWidget for selecting, hiding, showing, expanding and collapsing
|
||
|
nodes.
|
||
|
|
||
|
* Ensured that changes to items are reported.
|
||
|
|
||
|
- QLocale
|
||
|
|
||
|
* Fixed bug in the string-to-number functions which sometimes caused
|
||
|
them to fail on negative numbers which contained thousand-
|
||
|
separators.
|
||
|
|
||
|
* Implemented the numberOptions property for specifying how
|
||
|
string-to-number and number-to-string conversions should be
|
||
|
performed.
|
||
|
|
||
|
- QMainWindow
|
||
|
|
||
|
* Added support for tabbed dock widgets.
|
||
|
|
||
|
* Enhanced look and feel of dock widget handling. When a dock widget
|
||
|
hovers over a main window, the main window animates the existing
|
||
|
dock widgets and main area to show how it will accept the dock
|
||
|
widget if dropped.
|
||
|
|
||
|
* Fixed issues related to insertToolBarBreak().
|
||
|
|
||
|
- QMap
|
||
|
|
||
|
* Prevent conversion of iterator or const_iterator to bool
|
||
|
(e.g., if (map->find(value))), because the conversion always
|
||
|
returned true. Qt 4.1 code that doesn't compile because of this
|
||
|
change was most probably buggy.
|
||
|
|
||
|
* Added the uniqueKeys() function.
|
||
|
|
||
|
- QMenu
|
||
|
|
||
|
* Added the aboutToHide() signal.
|
||
|
|
||
|
* Added the isEmpty() accessor function.
|
||
|
|
||
|
* Clear menuAction() when setMenu(0)
|
||
|
|
||
|
* Added support for widgets in menus via QWidgetAction.
|
||
|
|
||
|
* Collapse multiple consecutive separators. This can be turned off
|
||
|
with the collapsibleSeparators property.
|
||
|
|
||
|
* Made scrollable menus wrap, just like non-scrollable ones.
|
||
|
|
||
|
- QMessageBox
|
||
|
|
||
|
* Updated the API to allow more than 3 buttons to be used.
|
||
|
|
||
|
* Added support to display buttons in the order required by
|
||
|
platform-specific style guidelines.
|
||
|
|
||
|
* Added support for display of informative text using the
|
||
|
informativeText property.
|
||
|
|
||
|
* Added the detailedText property to allow detailed text to be
|
||
|
displayed.
|
||
|
|
||
|
* Improved sizing of message box (especially on Mac OS X).
|
||
|
|
||
|
* Changed the behavior so that long text strings are automatically
|
||
|
wrapped.
|
||
|
|
||
|
* Updated icon handling to use QStyle::standardIcon() where possible.
|
||
|
|
||
|
- QMetaObject
|
||
|
|
||
|
* Added the userProperty() and normalizedType() functions.
|
||
|
|
||
|
- QMetaType
|
||
|
|
||
|
* Ensured that all type names are normalized before registering them.
|
||
|
|
||
|
* Added support for handling Qt's integer typedefs: qint8, qint16,
|
||
|
etc.
|
||
|
|
||
|
- QModelIndex
|
||
|
|
||
|
* Added the flags() convenience function.
|
||
|
|
||
|
- QMutexLocker, QReadLocker, and QWriteLocker
|
||
|
|
||
|
* These classes now track the state of the lock they are holding.
|
||
|
They will not unlock on destruction if unlock() has been called.
|
||
|
|
||
|
- QObject
|
||
|
|
||
|
* thread() will always return a valid thread, even if the object was
|
||
|
created before QApplication or in a non-QThread thread.
|
||
|
|
||
|
* When thread() returns zero, events are no longer sent to the object.
|
||
|
(Previous versions of Qt would send posted events to objects with no
|
||
|
thread; this does not happen in Qt 4.2).
|
||
|
|
||
|
* Added support for dynamically added properties via the new
|
||
|
property(), setProperty(), and dynamicPropertyNames() functions.
|
||
|
|
||
|
* Fixed a crash that could occur when a child deleted its sibling.
|
||
|
|
||
|
- QPainter
|
||
|
|
||
|
* Fixed a crash the occurred when drawing cosmetic lines outside the
|
||
|
paint device boundaries.
|
||
|
|
||
|
* Fixed a pixel artifact issue that occurred when drawing cosmetic
|
||
|
diagonal lines.
|
||
|
|
||
|
* Fixed opaque backgrounds so that they are identical on all
|
||
|
platforms.
|
||
|
|
||
|
* Optimized drawing of cosmetic lines at angles between 315 and 360
|
||
|
degrees.
|
||
|
|
||
|
* Added the setRenderHints() function.
|
||
|
|
||
|
* Fixed a memory corruption issue in drawEllipse().
|
||
|
|
||
|
- QPixmap
|
||
|
|
||
|
* Fixed crash caused by setting a mask or alpha channel on a pixmap
|
||
|
while it was being painted.
|
||
|
|
||
|
* Changed load() and save() to no longer require a format string.
|
||
|
|
||
|
* Ensured that grabWidget() works before the specified widget is first
|
||
|
shown.
|
||
|
|
||
|
- QPluginLoader
|
||
|
|
||
|
* Added errorString() to report the causes of errors when plugins fail
|
||
|
to load.
|
||
|
|
||
|
- QPrinter
|
||
|
|
||
|
* Added support for PostScript as an output format on all platforms.
|
||
|
|

|
* Related to changes to QObject, currentThread() always returns a
|
||
|
valid pointer. (Previous versions of Qt would return zero if called

|
||

|
||

|
||
|
the model a way to dynamically populate the children.
|
||
|
|
||
|
* Fixed issue where an item could expand when all children were
|
||
|
hidden.
|
||
|
|
||
|
* Added support for horizontal scrolling using the left/right arrow
|
||
|
keys.

|
* Fixed memory corruption that could occur when inserting and removing

|
||
|
(i.e., QTextCodec::codecForLocale()->name() returns "System"
|
||
|
when iconv(3) support is enabled).
|
||
|
|
||
|
|
||
|
AIX
|
||
|
---
|
||
|
|
||
|
- The makeC++SharedLib tool is deprecated; use the "-qmkshrobj" compiler
|
||
|
option to generate shared libraries instead.
|
||
|
|
||
|
|
||
|
X11
|
||
|
---
|
||
|
|
||
|

|
* Fixed assertion caused by interrupting a drag and drop operation
|
||
|
with a modal dialog on X11.
|
||
|
|
||
|

|
||
|
now working properly. QMimeData reports non-textual data offered in
|
||
|
Motif Drops using a MIME type of the form "x-motif-dnd/ATOM", where
|
||
|
ATOM is the name of the Atom offered by the Motif application.
|
||
|

Mac OS X
|
||
|
--------
|
||
|
|
||
|
- Mac OS 10.2 support dropped.
|
||
|
|
||
|
- QuickDraw support in QPaintEngine dropped; everything folded into the
|
||
|
CoreGraphics support.
|
||
|
|
||
|
- All libraries in Qt are now built as frameworks when -framework mode is
|
||
|
selected (default) during the configuration process.
|
||
|
|
||
|
- Many accessibility improvements, including better VoiceOver support. The
|
||
|
following widgets have had their accessibilty updated for this release:
|
||
|
QSplitter, QScrollBar, QLabel, QCheckBox, QRadioButton, QTabBar,
|
||
|
QTabWidget, QSlider, and QScrollBar.
|
||
|
|
||
|
- Hidden files are now reported as hidden by QFileInfo, QDirModel, etc.
|
||
|
|
||
|
- Windows now have a transparent size grips, an attribute for specifying an
|
||
|
opaque size grip was added.
|
||
|
|
||
|
- Metrowerks generator has been removed.
|
||
|
|
||
|
- Ensured that the anti-aliasing threshold setting is followed.
|
||
|
|
||
|
- Added a standard "Minimize" menu item to Assistant's Window menu.
|
||
|
|
||
|
- The documentation now has "Xcode-compatible" links so that it can be added
|
||
|
into Xcode's documentation viewer. This needs to be done by the developer
|
||
|
as regenerating Xcode's index takes quite a long time
|
||
|
|
||
|
- QAbstractScrollArea
|
||
|
|
||
|
* Improved look and feel by aligning the scroll bars with the size
|
||
|
grip.

|
* Data copied to the clipboard now stays available after the
|
||
|
application exits.

||
|
|
||
|
* Added support for the Find clipboard buffer.
|
||
|
|
||
|
* Fixed encoding of URLs passed as MIME-encoded data.
|
||
|
|
||
|
- QComboBox
|
||
|
|
||
|
* Improved the popup sizing so it's always wide enough to display its
|
||
|
contents.
|
||
|
|
||
|
* Improved the popup placement so it stays on screen and does not
|
||
|
overlap the Dock.
|
||
|
|
||
|
* The minimumSizeHint() and sizeHint() functions now honor
|
||
|
minimumContentsLength.
|
||
|
|
||
|
- QKeyEvent
|
||
|
|
||
|
* The text() of a QKeyEvent is filled with the control character if
|
||
|
the user pressed the real Control key (Meta in Qt) and another key.
|
||
|
This brings the behavior of Qt on Mac OS X more in line with Qt on
|
||
|
other platforms.
|
||
|
|
||
|
- QLibrary
|
||
|
|
||
|
* Removed the dependency on dlcompat for library loading and resolving
|
||
|
in favor of native calls. This means that you can unload libraries
|
||
|
on Mac OS X 10.4 or later, but not on 10.3 (since that uses dlcompat
|
||
|
itself).
|
||
|
|
||
|
- QMacStyle
|
||
|
|
||
|
* QMacStyle only uses HITheme for drawing now (no use of Appearance
|
||
|
Manager).

|
|
||
|
* Fixed placement of text on buttons and group boxes for non-Latin
|
||
|
locales.
|
||
|

|
||
|
button when the size gets too small.
|
||
|
|
||
|
* Draws the focus ring for line edits when they are near the "top" of
|
||
|
the widget hierarchy.
|
||
|
|
||
|
* Ensured that the tickmarks are drawn correctly.
|
||
|
|
||
|
* Implemented the standardIconImplementation() function.
|
||
|
|
||
|
* Fixed the look of line edits.
|
||
|
|
||
|
* "Colorless" controls now look better.
|
||
|
|
||
|

|
||
|
better with the native style.
|
||
|
|
||
|
- QMenu
|
||
|
|
||
|
* Popups no longer show up in Expose.
|
||
|

|
||
|
|
||
|

|
||
|
become a sheet.
|
||
|
|
||
|
* Improved the look of the icons used to fit in with the native style.
|
||
|
|
||
|
- QPainter
|
||
|
|
||
|
* Fixed off-by-one error when drawing certain primitives.
|
||
|
|
||
|
* Fixed off-by-many error when drawing certain primitives using a
|
||
|
scaling matrix.
|
||
|
|
||
|
* Fixed clipping so that setting an empty clip will clip away
|
||
|
everything.
|
||
|
|
||
|
* Fixed changing between custom dash patterns.
|
||
|
|
||
|
* Added combinedMatrix() which contains both world and viewport/window
|
||
|
transformations.
|
||
|
|
||
|
* Added the setOpacity() function.
|
||
|
|
||
|
* Added MiterJoins that are compliant with SVG miter joins.
|
||
|
|
||
|

|
||
|
|
||
|

|
||
|
|
||
|

||
|
|
||
|
* Made QPrinter objects resuable.
|
||
|
|
||
|

|
||
|
* Always use UTF-8 encoding when passing commands.
|
||
|
|
||
|
- QScrollBar
|
||
|
|
||
