Also I want to stop, >pause process.) you are already using threads, so this is enough. the problem, i think, is that GObject signals are not inherently cross-thread constructs. Emitting a signal from your computation thread and hoping that the view will update itself correctly will only work if you are doing the appropriate locking/unlocking using gdk_threads_enter() and gdk_threads_leave(). Otherwise you have two threads potentially trying to do GUI operations at the same time, leading to many problems. >The problem here is that although "changed" signal recieved, it's not >procesed by view, as computation function in other thread, continue it's >work, and so do not allow to update views and sends another signal. i don't entirely understand this sentence. --p _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
