Is this still an issue? I think by now you can work on okular KF5, using KIO's thread safety in KF5, no? Otherwise you need to go via the main thread for everything, e.g. using signal/slot connections to request a kio operation in the main thread and to receive the result in the secondary thread later. -- David Faure, fa...@kde.org, http://www.davidfaure.fr Working on KDE Frameworks 5 >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
