Sorry, no. If you need to have a global static to store information, then it sounds wrong. I agree we should use ints, enums and opaque pointers when wrapping a third-party API that is like that. If they have a global table, that's their business. But we should not add more global tables. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
