Qt 3.0 beta 5 is not binary compatible with beta 4; any programs
|
||
linked against beta 4 must be recompiled.
|
||
|
||
Below you will find a description of general changes in the Qt
|
||
Library and Qt Designer followed by a detailed list of changes in the
|
||
API.
|

The Qt Library
|
||
========================================
|
||
|
||
Documentation
|
||
-------------
|
||
|
||
The extensive revision of Qt classes' documentation is complete. The
|
||
front page of the Qt documentation (index.html) has been redesigned
|
||
to provide better access to other documentation than class
|
||
documentation.
|
||
|
||
OpenGL Module
|
||
-------------
|
||
|
||
Qt beta 5 provides some fixes which will make rendering GL widgets to
|
||
pixmaps work on a wider range of X servers.
|
||
|
||
QDateTimeEdit
|
||
-------------
|
||
|
||
The QDateTimeEdit, QDateEdit and QTimeEdit widgets have been moved
|
||
from the SQL module to the Qt core widget set. All users of Qt can
|
||
now use these widgets.
|
||
|
||
|
||
Qt Designer
|
||
========================================
|
||
|
||

|
||
|
||
- The generation of code related to QSqlCursor has been fixed.
|
||
|
||
- When removing a slot implementation from the Qt Designer
|
||
interface, do not accidentally remove a preceding comment.
|
||
|
||
- Improved the C++ code indenter in the editor for some C++
|
||
constructs, including try-catch blocks.
|
||
|
||
|
||
Qt Linguist

||
========================================
|
||
|
||
- Fixed problem with loading phrase books containing non-ASCII
|
||
characters.

||

|
||
|
||
- Fixed a rare crash when the database is deleted while its popup is
|
||
still open.
