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.
|
||
|
|
Applications compiled for 4.6 will continue to run with 4.7.

|
|
--------------
|
||
|
|
|
||
|
|
- 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
|

|
|
---------------
|

|
|
- [QTBUG-13772] Returning form fullscreen mode causes assertion failure.

- [QTBUG-14023] Added missing plugins to debug-libs package.
|
||
|

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).
|
||
|
|
- Phonon MMF backend
|
||
|
|
* [QTBUG-11436] Added a MediaObject property which allows the client to
|
||
|
|
specify which Internet Access Point should be used for streaming.
|
||
|
|
- QApplication
|
||
|
|
* [QTBUG-15915] Fix crash when creating more than one QApplication in single
|
||
|
|
test case.
|
||
|
|
* [QTBUG-16065] QApplication object with QApplication::GuiServer type caused
|
||
|
|
crash on Symbian devices.
|
