Qt 4.5.2-tower
---------------
The Qt for S60 "Tower" release is the fifth pre-release from the Qt for
S60 porting project. "Tower" is based on the Qt 4.5 codebase (mostly Qt 4.5.2).
This list of changes lists S60 specific fixes only,
for general 4.5.x changes go to:
http://qt.nokia.com/developer/changes/changes-4.5.0
http://qt.nokia.com/developer/changes/changes-4.5.1
http://qt.nokia.com/developer/changes/changes-4.5.2 (partially in Tower)
Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Task Tracker:
http://qt.nokia.com/developer/task-tracker
Each of these identifiers can be entered in the task tracker to obtain
more information about a particular change. Sometimes the task is internal
and cannot be viewed by the public, a lot of them are non-public for Qt for
S60 at the moment.
****************************************************************************
* New features *
****************************************************************************
New modules
-----------
- Input methods
* Added events to support opening and closing the virtual keyboard, called
software input panel in Qt.
* Added an option to QApplication to choose between single or double click
input panel activation.
* Added input method hints API to Qt. These can be used to instruct input methods
to only allow certain characters or tailor their appearance.
* Added Qt::ImAnchorPosition to support querying for selections through input
methods.
* Added QInputMethodEvent::Selection to support setting the selection through
input methods.
- Phonon
* The Phonon library is now part of Qt, but it comes without a backend.
This means that applications can build and run against the Phonon
library, but there is currently no S60 backend plugin providing actual
multimedia playback. Possible alternatives such as Helix and MMF are
being investigated.
- QtSql
* Implemented QtSql module with sqlite3 backend. For now backend is
provided only in binary format.
- QtWebkit
* Experimental webkit build for S60. Can be enabled by passing -webkit
to configure.
New classes
------------
- QScopedPointer
* Smart pointer, which deletes pointer when destroyed.
Ported classes
--------------
- QColormap
* Added basic implementation of QColormap for Symbian.
- QLocalSocket and QLocalServer
* Added support for QLocalSocket and QLocalServer on Symbian.
- QSound
* Implemented CMdaAudioPlayerUtility based Symbian backend for QSound.
Features
--------
- QApplication
* Implemented QApplication::beep() for Symbian.
- QPixmap
* Added supported for converting to/from CFbsBitmap
- QSslSocket
* Added support for -openssl option i.e. runtime resolving of OpenSSL
symbols.
- QWidget
* Basic widgets are now navigatable and usable via keypad on SDK 3
FP 1 and FP 2.
* Widgets can now be made semi-transparent on systems that support it
using Qt::WA_TranslucentBackground.
- Exception safety
* Improving the exception safety of Qt, not yet complete.
* Added support for translating between Symbian leaves and standard C++
exceptions.
Optimizations
-------------
- qdrawhelper
* Optimized drawing operations for RVCT builds, particulary for ARMV6.
- QFont
* Use cached DPI for metrics.
- qwidget_s60.cpp
* Avoid unnecessary calls to FocusChanged in Symbian.
- qwindowsurface_s60.cpp

Documentation
-------------
- exceptionsafety.qdoc
* A guide to exception safety in Qt.
- symbian-exceptionsafety.qdoc
* A guide to integrating exception safety in Qt with Symbian.
****************************************************************************

****************************************************************************
* Plugins *
****************************************************************************
- S60 version specific plugins

run on any supported device, even if with reduced functionality on
some.
****************************************************************************

- Qt libs
* Qt libs are now built with "All -Tcb" capabilities always. It is now
