Well, before gtk_show_uri came around, the way to do this was to use libgnome (http://library.gnome.org/devel/libgnome/stable/libgnome-gnome-help.html). This library is now deprecated, but you could still use it if you want to. Otherwise I guess you could resort to a hack like we've done in nemiver. regarding displaying a uninstalled help file, did you try the following format? file:///path/to/file.xml (three '/' characters) _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
