Hi all, I am working on developing a gui for my application which runs many posix threads. These threads will try to update the text view by adding text. this is how the i have written the code gtk_text_buffer_get_bounds(buffer,&start,&end); gtk_text_buffer_insert(buffer,&end,printbuffer,strlen(printbuffer)); Some times i get Gtk-CRITICAL **: gtk_text_layout_real_invalidate: assertion `layout->wrap_loop_count == 0' failed Gtk-WARNING **: Invalid text buffer iterator: either the iterator is uninitialized, or the characters/pixbufs/widgets in the buffer have been modified since the iterator was created. You must use marks, character numbers, or line numbers to preserve a position across buffer modifications. You can apply tags and insert marks without invalidating your iterators, but any mutation that affects 'indexable' buffer contents (contents that can be referred to by character offset) will invalidate all outstanding iterators After some searching i found that this due to some threading issue with gtk. I also used g_thread_init () and gdk_threads_init() , gdk_thread_leave and gdk_thread_enter as specified in the following link, http://mail.gnome.org/archives/gtk-a.../msg00086.html this works but this slows down my updation of the MMI quite considerably which i dont want. Is there any other alternative for this or if some one has worked on the following lines before and has got it to work please let me know. Cos this is very urgent. Regards S.Suresh Stephen
