1. Python/C++ Bindings Generator SIP is a tool for generating bindings for C++ classes with some ideas borrowed from SWIG, but capable of tighter bindings, because it's specific to C++ and Python. SIP was originally designed to generate Python bindings for KDE and so has explicit support for the signal slot mechanism used by the Qt/KDE class libraries. Features: - connecting Qt signals to Python functions and class methods - connecting Python signals to Qt slots - overloading virtual member functions with Python class methods - protected member functions - abstract classes - enumerated types - global class instances - static member functions.
