I expect that I sholud read KConfig configurations from certain method, which is excuted by separate threadweaver. The method is used to parse project files, and uses separate thread to not block GUI. Question is whether KSharedConfig is thread-safe or not. The techbase tutorial says that It thus provides a way to reference the same configuration object from multiple places in your application without the extra overhead of separate objects or concerns about syncronizing writes to disk even if the configuration object is updated from multiple code paths. But I'm not sure whether the above paragraph means thread-safety or not. Or is it ok just to read from KConfig, not writing? >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
