Values of Listbox with Seesaw

Question

is there any way i can get the values of a Listbox in seesaw as a collection, that Clojure can handle?

The most i've got was a JList, which Clojure can't handle.

/edit: To Clarify: For Example i want to get all of the Elements of a Listbox and conj a new Element onto them. But Because the return value of the listbox is a JList, Clojure naturally can't do that.

I can't seem to find any method to extract all Elements from the listbox.

What do you mean by "can't handle"? There should be no functionality you cannot access using the proper interop methods (ie. `(.getModel jl)`) — noisesmith, Feb 18 '14 at 17:18
the JList docs mention that the list should not be modified - you would want to empty it and recreate the list anyway, even in Java — noisesmith, Feb 18 '14 at 18:12

See this. You can use getModel method to get ListModel. And then use getElementAt and getSize method to build array or list or whatever you want.

(def data (into-array String ["one" "two" "three" "four"]))
(def myList (JList. data))
(->> myList 
    .getModel 
    ((juxt identity (memfn getSize))) 
    ((fn [[a b]] (map #(.getElementAt a %) (range b)))) 
    (apply vector) (#(conj % "five")))
