Qt 2.2.1 is a maintainance release. It keeps backward binary compatibility
|
|
with Qt 2.1 and both forward and backward source compatibility with Qt 2.2.x.
|
|
|
|
Qt 2.2.0 had a binary compatibility problem with the following:
|
|
|
|
bool QRect::contains( const QRect &r, bool proper=FALSE ) const
|
|
|
|
Qt 2.2.1 corrects this. Programs compiled with 2.1.x now continue
|
|
running with 2.2.1. Programs compiled with versions other than 2.2.0
|
|
may not run with 2.2.0, so upgrading to 2.2.1 is additionally important.

|
|
|
|
- Various compilation problems on particular platforms fixed
|
|
|
|
- Many improvments in QThread. More platforms supported
|
|
(e.g. HPUX 11.x), uses native threads on Solaris rather than
|
|
compatibility posix threads
|
|
|
|
- A few newly discovered memory leaks and free memory reads fixed
|
|
|
|
- As usual, many minor bugfixes, too small to be mentioned here.

****************************************************************************
|
|
|
|
- in KDE mode: don't show all KDE widgets in the toolbars, since we do
|
|
not have icons for them (yet). They are accessible through the menu
|
|
structure, though.
|
|
|
|
- Introduced concept of a global /etc/designerrc and a templatePath
|
|
for the sake of Linux Standard Base (LSB) and the way Linux
|
|
ditributors like to package the Qt Free Edition.
|
|
|
|
- Support for tab names in a QTabWidget, and page names in a QWizard.
|
|
|
|
- Support for button IDs in a button group, makes it possible to utilize
|
|
one single slot for all buttons in a group.

* Changes that might affect runtime behavior *

|

|
|
QLayout:
|
|
|
|
We synchronized the behaviour of sublayouts and subwidgets with
|
|
layouts. This shows great effect in the designer, were you usually
|
|
operate on container subwidgets in the design phase, but get a
|
|
complete layout in the preview mode or the generated code. For
|
|
example, the influence of a spacer item on a sublayout's size policy
|
|
has been reduced. The modifications may slightly affect the layout of
|
|
some dialogs.
