++ *                      Platform Specific Changes                           *

++ ****************************************************************************

++

++ Unix

++     * Made the iconv-based QTextCodec class (the "System" codec on

++       Unix systems that support it) stateful. So it's now possible to

++       feed incomplete multibyte sequences to the toUnicode function,

++       as well as the first character in a UTF-16 surrogate pair.

++

++ X11

++     * Added a QGtkStyle to integrate with GTK+ based desktop environments.

++     * If font config is used the default font-substitutions will no longer be

++       used instead we rely on fontconfig to determine font substitutions as

++       required.

++     * Improved support for KDE4 desktop settings.

++     * [214071] Improved support for custom freedesktop icon themes.

++     * [195256] Use FreeType's subpixel filtering if available, thus honoring

++       Font Config's LCD filter settings.

++     * Added supported for XFIXES X11 extension for proper clipboard

++       support when non-Qt application owns the clipboard.

++     * Icon support for top level windows (_NET_WM_ICON) was improved

++       to support several icons with different sizes.

++     * [211240] In some cases QFileSystemWatcher didn't notify about

++       files that were moved over another files.

++     * [238743] Added support for the _NET_SYSTEM_TRAY_VISUAL property

++       to use the same visual the system tray manager asks us to use.

++     * [229593] Fix font matching with old fontconfig versions.

++     * [167873] Proper event compression for mouse events when using tablets.

++     * [208181] Fix averageCharWidth to be consistent for y!=x ppem

++     * [229070] Fix QPrintDialog assertion

++     * [211678] Fixed a problem with drawing a QPixmaps on different X11

++       screens.

++     * [221362] Fixed a problem where pixmaps only appeared on the first page

++       in a print preview.

++     * [232666] Fixed a problem with custom page sizes for CUPS printers.

++     * [228770] Fixed a problem that caused the .ps and .pdf filename

++       extensions

++       to not update in the CUPS printer dialog when printing to file.

++     * [230372] Fixed a problem where the number of copies set on a QPrinter

++       object wasn't picked up and updated properly in a QPrintDialog.

++

++ Windows

++     * Cleartype rendering was previously supported onto QImages with

++       an ARGB32 channel. For performance reasons, cleartype is now

++       only supported on opaque images using the RGB32 or

++       ARGB32_Premultipled format. Widget and pixmap rendering is

++       unchanged

++     * [175075] Antialiased font rendering quality has been greatly improved

++       by taking gamma correction into account. We should now match the native

++       Windows font rendering better, and the fonts look better in general when

++       drawing fonts on different backgrounds.

++     * [221132] Fixed a problem with System Tray menu visibility.

++     * [221653] Fixed a problem incorrectly causing a Task Bar status change.

++     * [202890] Improved platform consistency with spacing in menus.

++     * [157323] QCombobox now slides to open on relevant platforms.

++     * [237067] Calling showMessage on QSystemTrayIcon with empty arguments

++       now hides the current message.

++     * [145612] Setting an object name for a QThread sets the name that

++       is visible in the debugger for more easy debugging

++       multi-threaded application.

++     * [216664] QLocale now follows the current system locale when the

++       user changes it in the Windows Control Panel.

++     * [223921] Fix writing system detection of TrueType fonts added

++       via a QByteArray in QFontDatabase::addApplicationFont on Windows.

++     * [205455] 'mailto:' links works properly with QDesktopServices::openUrl().

++     * [205516] standardPalette() now returns the system palette for XP and

++       Vista styles.

++     * [207506] Fixed an issue which switches the alignment for input widgets

++       on Vista.

++     * [223951] Added support for VARIANT with IDispatch in ActiveQt.

++     * [224910] Fixed a crash when using the Hierarchy ActiveQt example.

++     * [201223] 'dumpcpp' now prepends the 'classname_' to resolve conflicts.

++     * [198556] QAxServer registering now takes care of '.' before MIME

++       extension.

++     * [223973] Fixed a deadlock in QLocalSocket.

++     * [193077] Fixed activation of ActiveQt widgets in MFC MDI applications.

++     * [238273] Fixed a crash while editing QTableView using japanese IME.

++     * [238672] Fixed a crash when deleting a widget while dragging.

++     * [241901] ActiveQt now supports [out VARIANT*] parameters.

++     * Fix a GDI object leak on the qfileiconprovider.

++     * [200269] Application and systray icons on Windows that had an alpha

++       channel were not drawn correctly.

++     * [239558] Fix a possible crash when reading XPM data containing trigraphs

++       with the Microsoft compilers.

++     * [204440] Fixed a problem with software rendering contexts on Windows,

++       which might have caused rendering errors due to to unresolved extension

++       pointers.

++     * [232263] Fixed a problem with binding textures to a software context

++       under Windows.

++     * [238715] Fixed a problem with alpha-blended cursors under Windows.

++     * [227297] and [232666] Fixed some problems with custom paper

++       sizes under Windows.

++     * [217259] The default printer wasn't correcly detected with some versions

++       of Windows.

++     * [212886] Fixed a problem with network printers not being listed by

++       the QPrinterInfo::availablePrinters() function under Windows.

++     * [205985] Fixed a problem with reusing a QPrinter object to print several

++       jobs with the Microsoft XPS printer driver.

++     * [196281] Fixed QPrinter::setPrintRange() to work under Windows.

++

++ Windows CE

++     * Support for QLocalSocket and QLocalServer added.

++     * QtWebKit and Phonon are now supported.

++     * One can mark a widget with the attribute WA_ExpectsKeyboardInput

++       to automatically display / hide the standard input panel on focus

++       events.

++     * [223523] Reimplementations of standard library functions filled the

++       global namespace causing problems when linking statically to other third

++       party libraries using the same attempt.

++     * Support for using OpenSSL with Qt on Windows CE

++

++ Mac OS X

++     * Added the macdeployqt tool that simplifies application deployment.

++     * Improved support of widget stylesheet in Mac.

++     * [218980] - Stacking order of windows and dialogs is fixed, such that

++       dialogs always floats above normal windows, even when the dialog is told

++       to behave as a window.

++     * [219844] - A crash that occurred when using the search buttons on a

++       native file dialog is fixed.

++     * [225705] - FileDialog filters not displaying correctly is fixed.

++     * [239155] - Pop-ups will now close when clicking on a window other than

++       the modal window that opened the pop-up.

++     * [210912] - Show event not sent when reshowing a window from minimized

++       state is fixed.

++     * [228017] - QMenu will now close when expanding a system menu.

++     * Added support for Qt to use Cocoa as its backend instead of Carbon. This

++       is primarily for 64-bit applications, but is also available for 32-bit

++       frameworks as well. 32-bit is still Carbon by default. Passing a 64-bit

++       architecture or -cocoa on the command-line will build Qt against Cocoa.

++       Using Cocoa requires Mac OS X 10.5 (or higher) and cannot be used with

++       the -static nor -no-frameworks option. The define QT_MAC_USE_COCOA is

++       available when Qt is built against Cocoa.

++     * Fix a bug that would prevent a window that had been maximized via

++       setMaximized() to go back to normal size when clicking on the window's

++       maximize button.

++     * Added QMacCocoaViewContainer for embedding Cocoa (NSView) controls into

++       a Qt hierarchy. This feature works for either Carbon or Cocoa, but

++       requires Mac OS X 10.5 or greater.

++     * Added QMacNativeWidget for embedding Qt widgets into non-Qt windows

++       (Carbon or Cocoa).

++     * Added MacWindowToolBarButtonHint for controlling whether or not the

++       toolbar button is shown in Qt windows.

++     * QEvents posted via QEventLoop::postEvent() are now treated as a standard

++       event loop source, like timers and normal input events. This means that

++       is should no longer be necessary to run a busy loop to sendPostedEvents()

++       when QApplication is not the main event loop (e.g. when using Qt in a

++       plugin).

++     * [239646] Shortcuts for sub-menu are now disabled when the menu item is

++       disabled.

++     * [241434] Honor the LSBackgroundOnly attribute if it exists in the

++       application's Info.plist.

++     * [239908] More robustness when encountering different types in reading

++       LSUIElement value.

++     * [234742] Add support Qt::XButton1 and Qt::XButton2.

++     * [236203] Much better support for loading multiple Qt's with different

++       namespaces.

++     * Add Qt::AA_MacPluginApplication that allows bypassing some native menu

++       bar initialization that is usually not desired when running Qt in a

++       plugin.

++     * [205297] Applications Dialogs are now marked as application modal in

++       Carbon.

++     * Tooltip base is now set correctly in the application palette.

++     * [222912] [241603] Qt applications no longer reset their palette back to

++       the system palette on every application activate. Only if the values

++       from the system are different from the last time. This should result in

++       custom palette colors/brushes being kept across application activations.

++     * [211758] Fixed a clipping problem when printing multiple pages on a Mac

++       OS X printer.

++     * [212884] Fixed a crash when printing images on Mac OS X.

++     * [219877] Fixed a problem with a QPrinter object not being valid after

++       setting the output format to PDF or PostScript.

++     * [229406] Fixed crash when display mirroring gets enabled.

++     * [189588] Fixed a bug where QColorDialog::getColor(...) always returned a

++       valid color.

++

++ Qt for Embedded Linux

++  - Screen drivers

++    * The SVGAlib driver is no longer supported, due to architectural changes.

++    * [235785] Detect VGA16 video mode and warn that it is not supported.

++

++  - Mouse and keyboard drivers

++    * [243374] Fixed bug where PC mouse driver could not be loaded when

++      configured as loadable plugins.

++    * Added Linux Input Subsystem mouse and keypad drivers

++

++  - General fixes

++    * [242922] Run as server by default when compiled with the

++      QT_NO_QWS_MULTIPROCESS macro defined.

++    * Fixed bugs where wrong cursor would be shown in some cases.

++    * Respect min/max size on initial show also for windows without a layout.

++    * Fixed loading of font plugins when QT_NO_FREETYPE is defined.

++    * Autodetect PowerPC in configure.

++    * Add support for precompiled headers.

++ ****************************************************************************

++

++ - Event filters

++

++ - QFileDialog

++         On Mac, native dialogs are now used when calling show, open, or exec

++         on a QFileDialog, QColorDialog, QPrintDialog, or QFontDialog (i.e not

++         only when using the static functions)

++

++         QFileDialog/QFileSystemModel always return Qt separators ("/")

++         regardless of the platform. It can still handle native separators for

++         Windows. To convert the Qt separators to native separators use

++         QDir::toNativeSeparators().

++

++ - QGraphicsTextItem

++         Tab input is send to the document by default, inserting a <tab>

++         character. You can get the old behavior of switching Tab focus by

++         setting setTabChangesFocus(true) (QGraphicsTextItem's Tab handling now

++         behaves identically to QTextEdit and QTextBrowser).

++

++ - QGraphicsView

++         QGraphicsView now propagates Qt::Key_Tab and Qt::Key_Backtab to the

++         scene, which sends this to the items. Similar to how QWidget works,

++         this event is caught in QGraphicsItem::sceneEvent() and

++         QGraphicsWidget::event() to handle tab input. Tab input is also

++         proxied to embedded widgets. This allows and item or widget to handle

++         Tab keys (e.g., text input).

++

++ - QLocale

++         The locale database was updated to the Unicode CLDR database

++         version 1.6.1

++

++         When the system locale is changed, the LocaleChange event will

++         be sent to all widgets that don't have a locale explicitely

++         set.

++

++ - QWebPage

++         Starting with Qt 4.5, the base brush is used for the default

++         background color of the web page. Before, it was the background

++         brush.

++

++ - QWidget

++         Font and palette settings assigned to QWidget directly take

++         precedence over application fonts and palettes.

++

++         Focus policies that are set on a widget are now propagated to

++         a focus proxy widget if there is one.

++

++         Windows with fixed size (that are set with QWidget::setFixedSize()

++         function or Qt::MSWindowsFixedSizeDialogHint window hint) might

++         not have a maximize button on the titlebar.

++

++         The behaviour of the window hints was changed to follow the

++         documentation. When the Qt::CustomizeWindowHint is set, the

++         window will not have a titlebar, system menu and titlebar

++         buttons unless the corresponding window hints were explicitely

++         set.

++

++         Setting Qt::WA_PaintOnScreen no longer has any effect on

++         normal widgets. The flag can still be used in conjuction with

++         reimplementing paintEngine() to return 0 so that GDI or

++         DirectX can be used, as previously documented.
