... full post: Hi, Davide, I don't know if I can provide the *best* method, but here is one that demonstrates several little tricks that may help: REBOL [] chatters: copy [] chat: make object! [ nome: copy "" frm: [ (to-set-word join 'titolo nome) h2 (join "Chatting with: " nome) area ] show: does [ view/new frm-chat: layout compose frm do [ append chatters to-word join 'titolo nome chatters: unique chatters ] ] ] chat1: make chat [ nome: "Davide" ] chat2: make chat [ nome: "Luca" ] view layout [ button "Show Davide" [chat1/show] button "Show Luca" [chat2/show] button "Print values" [ foreach chatter chatters [ print get in do chatter 'text ] ] ] Hope that helps. --Scott Jones
