This hasn't been wrapped as a sigc::slot<>, probably because I couldn't see when it would be useful. The documentation says "This is a low-level operation and makes it easy to break GDK and/or GTK+, so you have to know what you're doing" and that scares me a bit. This would be easy for someone to wrap properly. See the other SignalProxy_* classes in the .ccg files. A patch would be welcome. -- Murray Cumming murrayc@xxxxxxxxxxx www.murrayc.com www.openismus.com _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
