Here's the exercise with int. This is thread-safe: int f() { return 1; } auto x = f(); ++x; No matter how many threads call f(), all of them will get a value from f, can assign it to a variable and modify without caring what other threads do. Replace int with QMap or QString and you have the same behaviour. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
