Ok, I've got that part working. Now I have the problem that I need to exit the thread gracefully if a new set of thumbnails is requested and the thread is still running. Getting it to terminate gracefully and resetting the queue is not very difficult and I get it to terminate before the new thread is started (using a Cond), however, the get_next_thumb() function keeps accessing the queue because (I presume) there is still a number of outstanding signals left that it has to handle (at least one) and I get a double lock on the mutex.
I've tried bools, further dispatchers that are called when the thread is being terminated and when the termination is finished (they trigger a bool switch on the receiver end which prevents the next_thumb_ready signal from being acted upon) and Glib::Cond's and I still get deadlocks or segfaults when launching the new thread. Any ideas on how to keep that get_next_thumb() function from accessing the queue in a thread safe manner? Thanks. -Bartek _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
