aaa ok thanks a lot! I was under the impression that #() created a (fn
[& args] ...) !

this is because the #() checks for arguments used inside its body to
infer its arity. in #(alert "..") you don't use any arg so it creates
a function with no argument, such as doing (fn [] ..)

Hi everyone,
I was surprised to discover that anonymous functions will not work
in seesaw...For example the following throws an exception (wrong
number of args):
(button :text "Undo" :listen [:action #(alert "Not implemented!")])
but if i replace the anonymous fn with (fn [e] (alert "Not
implemented!")) it works just fine!!!the same is true for when
defining an action like so:
(action :handler (fn [e] (alert "Not implemented!"))
:name "Save"
:tip "Save a game to disk."
:key "menu S")
If it was an anonymous fn it would throw an exception...This is
very weird for me cos I know that anonymous fns take variable
number of args so i don't see what the problem is...any
explanations/suggestions?
Most of the ssesaw docs show examples using (fn [e] (... ...)) but
I'm sure I've seen snippets that use #(... ...). What is going on?
Jim
