If you are willing to put a lot effect into it, it is possible to use isigraph to build your own listbox with more custom events. You can get some idea by browsing the listview or grid in jwiki. That being said, I prefer waiting for gtk support in J7. -- regards, ==================================================== GPG key 1024D/4434BAB3 2008-08-24 gpg --keyserver subkeys.pgp.net --recv-keys 4434BAB3 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
