You'd get this error when trying to pack a widget into a Gtk[VH]Box when that widget is already contained (i.e. it has a parent). To re-pack a widget, you need to g_object_ref it, (assuming you don't hold a reference), remove it from its container (gtk_container_remove) and then you'll be able to pack it into the box successfully (remember to unref afterwards). Also note, GTK is not thread-safe, so GTK functions mustn't be called outside of the main thread. You can use gdk_threads_enter/leave, but it's generally easier to use idle callbacks (if you g_idle_add in a thread, the callback will happen in the thread of the mainloop, as opposed to whatever thread you called it from). Hope that helps! --Chris _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
