#### PyQt3Support - Python bindings for Qt3Support #### http://www.develer.com/oss/PyQt3Support #### What is this? PyQt3Support is an extension to PyQt4 that adds bindings to Qt's Qt3Support library for usage from the Python language. This is very helpful to migrate existing PyQt3 applications to PyQt4. #### Why? Porting from Qt3 to Qt4 can be tedious and bug-prone. For C++ programmers, Trolltech provides a library, called Qt3Support, that immensely helps. With Qt3Support, a C++ programmer basically only needs mechanical changes to your source code. The library is made of two different parts: * A new family of widgets (Q3*) with the same API of Qt3. * New member functions (or overloads) within standard Qt4 widgets. For Python programmers, the situation is worse: PyQt4 does not bind Qt3Support to Python. Developers of PyQt3 are forced to manually upgrade their code to PyQt4, class by class. This package fills the gap. By providing a new module PyQt4.Qt3Support, it enables PyQt3 developers to access Trolltech's migration library, and thus upgrade their code much easily and faster, with almost only mechanical changes. It's not a panacea of course: you probably still need minor manual adjustments and supervising, but it can still be of great help. #### Where? PyQt3Support has been developed and tested under both Windows (2000, XP, Vista) and Linux (Ubuntu, Fedora). #### License Qt3Support follows whatever license you have for PyQt3 and PyQt4, because its source code is machine-generated from PyQt3's and PyQt4's source code. Thus, Qt3Support can be freely used under both the GPL or the commercial license offered by Qt/PyQt producers. In case you are interested in developing Qt3Support itself, you want to know that the script that generates Qt3Support is released under the GPL license. #### Status PyQt3Support is not complete: it binds about 30% of the Qt3Support, but don't be fooled by this figure: it's the part that is probably used most in existing programs (more common widgets, constructors, ecc.). Moreover, since it is fully machine-generated, it is very easy to extend it to cover more classes and functions.
