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.
