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:+ −

+ − 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.+ −

software input panel in Qt.+ −
