| Qt 2.0 introduces a wide range of major new features as well as |
| substantial improvements over the 1.x series. The documentation has |
| been significally extended and improved. |
| |
| This file will only give an overview of the main changes since version |
| 1.44. A complete list would simply be too large to be useful. For |
| more detail see the online documentation which is included in this |
| distribution, and also available on http://qt.nokia.com/doc/ |
| |
| The Qt version 2.x series is not binary compatible with the 1.x |
| series. This means programs compiled with Qt version 1.x must be |
| recompiled to work with Qt 2.0. |
| |
| Qt 2.0 is mostly, but not completely, source compatible with Qt 1.x. |
| See the document "Porting from Qt 1.x to Qt 2.0" in the Online |
| Reference Documentation for information on how to port an existing Qt |
| 1.x-based program to Qt 2.0. Note in particular the automatic porting |
| script included - it does a lot of the work for you. |
| |
| As for 1.x, the API and functionality of Qt is completely portable |
| between Microsoft Windows and X11. And between Windows 95, 98 and NT: |
| Unlike most toolkits, Qt lets a single executable work on all three. |
