At the time of PySide creation (around the end of 2008) we studied various projects and *at the time* none of them had a reasonable C++ support, so PySide was started after some successful experiments made by Renato with Boost Python plus a modified version of a JavaScript binding generator, this Javascript binding generator was also a fork from QtJambi with their own workarounds, a year later Boost python proved to not be a good choice to create bindings for big libraries like Qt and we dropped it (Shiboken was born) but still using the same generator code base. I think a research about the current state of binding generators could be re- done nowadays, if a good solution without licensing problems was found drop shiboken for a better maintained tool could be a good step for the project. > Cheers, > > Henry > > _______________________________________________ > PySide mailing list > PySide@qt-project.org > http://lists.qt-project.org/mailman/listinfo/pyside
