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.
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.
What's New in This Release: [ read full changelog ]
· An upgrade to PyQt 4.4.3.
· Deprecated warnings support: this release uses the /Deprecated/ SIP annotation.
· The /Deprecated/ annotation raises a Python Warning when Qt3Support is used, both in plain Q3 classes and Qt3Support methods in Q4 classes.
