The bindings seem to be generated by a perl script and a quick web search revieled a related problem here: https://bugs.webkit.org/show_bug.cgi?id=42115 You should probably log a bug against WebKit Gtk to get the annotation fixed. Also, have you tried creating an empty WebKit.DOMXPathResult and passing that? >>> res = WebKit.DOMXPathResult() Is there any way to get underlying gobject pointer from python so that I > can use ctypes and try to call function directly.

But it is unclear if this would be useful in ctypes because it returns a PyCapsule. This attribute is used internally for some parts of PyGObject. However, we cannot support this officially as it is an implementation detail, so use at your own risk. You should also be able to create a small C extension to Python which wraps the function up for you. -Simon _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
