Qt 4.5.0-garden
|
||
|
|
---------------
|
||
|
|
|
||
|
|
The Qt for S60 "Garden" release is the fourth pre-release from the
|
||
|
|
Qt for S60 porting project. "Garden" is based on the Qt 4.5 codebase
|
||
|
|
and release focus has been on proper GUI integration.
|
||
|
|
|
||
|
|
Up to and including change: b7621555cb1d1c97967dd40d63dd7e85a418407c
|
||
|
|
|
||
|
|
Lists just S60 fixes, for general 4.5.0 changes go to:

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
|
||
|
|
-----------
|
||
|
|
|
||
|
|
- qtmain
|
||
|
|
* Added a small static library called qtmain which is linked in
|
||
|
|
automatically for Qt applications on S60. qtmain includes an
|
||
|
|
implementation of E32Main() that sets up Qt correctly for S60. This
|
||
|
|
means that Qt no longer links to libcrt0.lib but uses qtmain instead.
|
||
|
|
However, if you are not linking against QtGui, you'll still have to
|
||
|
|
link to libcrt0.
|
||
|
|
|
||
|
|
New classes
|
||
|
|
------------
|
||
|
|
|
||
|
|
- QS60Style
|
||
|
|
* Native look for Qt applications on S60 3.1 and later versions. The
|
||
|
|
style picks up the current theme parts, palettes and font settings
|
||
|
|
through the skinserver and uses these when painting in Qt.
|
||
|
|
The layout data for different resolutions is considered.
|
||
|
|
|
||
|
|
Ported classes
|
||
|
|
--------------
|
||
|
|
|
||
|
|
- QDesktopServices
|
||
|
|
* Provides methods for accessing common desktop services: Opening the
|
||
|
|
browser with an url, launching documents with the standard application
|
||
|
|
and getting default system directories.
|
||
|
|
|
||
|
|
- QClipboard
|
||
|
|
* Provides access to the window system clipboard.
|
||
|
|
|
||
|
|
- QSysInfo
|
||
|
|
* QSysInfo class provides information about the system.
|
||
|
|
|
||
|
|
Features
|
||
|
|
--------
|
||
|
|
|
||
|
|
- Input methods
|
||
|
|
* QInputMethodEvent will now be generated by Qt.
|
||
|
|
To use it, widgets must set the attribute WA_InputMethodEnabled and
|
||
|
|
implement QWidget::inputMethodQuery(...).
|
||
|
|
* Qt will use the underlaying FEP framework from S60.
|
||
|
|
* Multitap and T9 supported.
|
||
|
|
* Virtual keyboard for touch phones is supported.
|
||
|
|
* Most of the Qt widgets already have support for input methods.
|
||
|
|
|
||
|
|
- Drag-n-Drop
|
||
|
|
* At the moment works only within same Qt process.
|
||
|
|
|
||
|
|
- STL support for QtS60
|
||
|
|
* use -stl switch when configuring Qt.

||
