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 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.

|
using Qt::WA_TranslucentBackground.
|

|
AknAppUi::SetOrientationL.
