That's the right way of doing it. Only the main thread should be drawing stuff into the widgets. There is another way too: using gdk_threads_init, gdk_threads_enter and gdk_threads_leave you control which thread is updating the widgets at any specific time, but sending signals to the main thread is a cleaner interface than using gdk_threads_enter and gdk_threads_leave every time you want to update the view About that quick example you were asking for have a look at this http://wiki.inkscape.org/wiki/index.php/Using_libsigc%2B%2B_signals. Here there is another one http://lsjandysf.spaces.live.com/blog/cns!54FF19028BDE00EA!1113.entry though it can be too simple _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
