How could I allow only unique strings in a JList ?

I have a JList that holds a bunch of strings . I would like it to act like a Set , so that it will only hold unique values . Is there any way to achieve this without checking that a new string doesn't already exist there ?

• Hi,

  take a look at the docs: 1.4.2 | Java 6

  You can set your own ListModel via JList#setModel(ListModel) which might be backed by e.g. a HashSet instead of the Vector which is used by default.

  See also ListModel and AbstractListModel

  Tom Hawtin - tackline : LinkedHashSet would make more sense, but it'd still be an awkward O(n^2) operation to, say, repaint the widget.
