I tried this; here is the result :

2005-11-08 22:42:32.463 SimpleStickies[1306] KVO autonotifying only =20
supports -set<Key>: methods that return void.  Autonotifying will not =20=

be done for invocations of -[Note setText:].

Same error is produced for each atribute.
What is the syntax of the second parameter to =20
'addRubyMethod_withType' ?  It does not seem to acknowledge that =20
'void' is returned, although the initial @ is preceded by nothing (no =20=

type).

By the way, why define "#{key}" (without ':') and "#{set_key}:" (with =20=

':') ?  [sorry for silly newbies' questions]

For the moment, I will leave that to the experts  :-)

Thanks for you help.
