Revision 7e0fa2fc75a9c9ca3466d0a3fb6c9f302fc22a62 authored by Marc Mutz on 10 July 2012, 13:27:48 UTC, committed by Qt by Nokia on 26 August 2012, 12:29:49 UTC
Currently, we have a C++11 version that requires Q_COMPILER_DECLTYPE support, and can deal with final classes, and a C++98 version that doesn't require any C++11 features, but fails on final classes. What we're missing is a version that works for MSVC v8 and v9 (2005 and 2008), which sport the 'sealed' non-standard keywords but lack decltype support. So far, we tried to solve the problem by making class-level final special (Q_DECL_FINAL_CLASS), not defining that macro for these two compilers, even though we did define Q_DECL_FINAL, the method-level keyword. This new formulation, taken from http://stackoverflow.com/a/9655327/134841 supposedly supports all compilers with a minor #ifdef for MSVC which doesn't like applying sizeof() the way we do. However, testing has shown this to blow up on OSX. So we use the less intrusive approach: add this variant as a third version, only used by VC 2005 and 2008.

Qt 4.7.2 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.7.0. For more details,
refer to the online documentation included in this distribution. The
documentation is also available online:
http://qt.nokia.com/doc/4.7
The Qt version 4.7 series is binary compatible with the 4.6.x series.

****************************************************************************
* Platform Specific Changes *
****************************************************************************
Qt for Linux/X11
----------------
- [QTBUG-15008] Fix broken prefix setting in configure when EPOCROOT shell
variable is set.
Qt for Windows
--------------
- QtQuick
* [QTBUG-16885] QDeclarativeEngine::addImportPath() did not work if the
drive letter is in lowercase.
* [QTBUG-17360] Make sure $QTDIR/plugins/qmldebugging/tcpserver.dll is
found in windows release builds.
Qt for Mac OS X

Qt for Symbian
--------------
- Multimedia
* [QTBUG-17040] Prevent menu and native title pane area popping up when
setting fullscreen mode off during video playback.
- Packaging changes
* [QTBUG-17399] Remove sqlite3 from Qt SIS for S60 3.2 and 5.0 to allow
Nokia Content Signing, which doesn't permit sis files to have other
sis files embedded inside.
- Paging changes
* [QT-3503] Remove PAGED keyword from all Qt-based binaries for
MMP-based build systems (abld, SBSv2 (a.k.a. Raptor)).
This changes the code paging field in the Symbian (E32Image) header
from "paged" to "default". Thus it is left to the configuration
of the particular device whether paging is used for the binary or
not. All devices that support code paging should have it turned
on (the value is stored in the HAL, so can be checked using eg.
fshell); data paging may or may not be turned on depending on the
device characteristics. Leaving both code and data paging as
"default" means that any limitations in the device (eg. around
flash wear) can be controlled by that device by disabling the
appropriate types of paging rather than being forced by the binary
(which may be deployed to several different devices with different
characteristics).

- QWidget
* [QTBUG-16578] In cases where the widget was created from the event loop
instead of main(), the middle three softkeys would not get the right
visibility and would leave a "hole" in the application where one could
see what was beneath it.
* [QT-4416, QTBUG-17288] On devices which lack support for transparency
in EGL surfaces, setting Qt::WA_TranslucentBackground on a widget
