Support for a selectionMode in JList and ListSelectionModel, was never
implemented (as of Swing0.6) It did make it into TreeSelectionModel. This is basic list functionality.

Subject: BUG: JList Non-Contiguous Multiple Selection
Date: Thu, 13 Nov 1997 15:47:00 -0600

It seems that BasicListUI only allows multiple selection of contiguous
items. Is there a way to do non-contiguous multiple selection?

As far as I can tell, BasicListUI does not allow non-contiguous multiple
selection, even though it is supported via
ListSelectionModel.addSelectionInverval().

Unless I am mistaken, the only way to have non-contiguous multiple
selection in a list is to implement a new look and feel - ugh.
Hopefully, I'm mistaken.

btw, the javadoc for JList is confusing regarding this point:

    "A component that allows the user to select one or more objects from
a list ..."
and later on ...
    "By default JList supports single selection, i.e. zero or one index
can be selected..."

It seems to me that neither statement is accurate.


PS: I'd really appreciate it if someone could either point out how to
do non-contiguous multiple selection in a JList, or verify that it's
currently not implemented. Thanks.
