> How can we pass a String array (char **) to value-clicklistV inset.

One way to do this is with the ness functions value_SetArraySize and
value_SetArrayElt as documented in $ANDREWDIR/doc/atk/ness/nessfunc.doc.

But first you have to fix the bug I just discovered.  The changes will
appear on a forthcoming patch, but not patch 7.  Unofficially you just
need to add two lines to atk/ness/objects/nevent.c (The line numbers may
incorrect because r1.22 is later than patch level 7):

diff -c -r1.22 nevent.c
*** /tmp/,RCSt1000326	Tue Sep 18 10:15:09 1990
--- nevent.c	Tue Sep 18 10:00:59 1990

  		sar = (unsigned char **)value_GetStringArray(vobj);
  		sar[index] = s;
+ 		value_NotifyObservers(vobj, value_NEWVALUE);
  	}	break;
  	case 'v':		/* value_setnotify(obj, bool) */
  		/* NSP = unstackBool(NSP, iar, &v); */


To try out the test below, empower the Ness and select DoMain from the
Ness menu card.  This should make three options appear in the currently
empty clicklistV (but only after the repair to nevent.c noted above).  A
click on an option in the clicklistV will echo in the message line.
