I have defined a presentation-type, column, as well as the appropriate present and accept methods. I need to accept a list of column objects from the user, but I am a bit stumped on how to do this. Do I have to define a new "columns" type, or does McCLIM include facilities to automatically read in sequences of objects from the user? -- \ Troels "Athas" Henriksen /\ sigkill.dk/blog (Danish)
