| 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. |

| * General * |
| **************************************************************************** |
| |
| - 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. |
| |

| **************************************************************************** |
| * Designer * |
| **************************************************************************** |
| |
| - 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. |
| |
