* 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

* [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

* 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

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.

* Important Behavior Changes *
****************************************************************************
- 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.
