changes-4.5.2-tower

++ 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.

++       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.

++

++       AknAppUi::SetOrientationL.

++     * Generating MouseEvents has gone through several changes.

++

++ - QNetworkInterface

++     * Fixed R-handle leak in Symbian version of qnetworkinterface_unix.cpp.

++     * Introduced a new qnetworkinterface_symbian.cpp, because there wasn't

++       really anything common to UNIX equivalent.

++

++     * Added fromSymbianCFbsBitmap() and toSymbianCFbsBitmap().

++

++ - QPlainTextEdit

++     * Added support for virtual keyboard.
