public class DualList
extends JideSplitPane

DualList is a pane that contains two JLists and a bunch of buttons. The list on the left contains all the items. The list on the right contains the items that are selected.

DualList uses DualListModel which is the model of this component. With the help of DualListModel, it provides three kinds of selection modes. This mode controls what to display in the right list when items are selected. DualListModel.REMOVE_SELECTION mode means the left list will remove the items if they are selected to the right list. This mode can prevent user from selecting the selected item again if it is not allowed in certain cases. DualListModel.DISABLE_SELECTION mode means the selected items will be shown as disabled. User cannot select them anymore but they can still see them in the right list to show user a complete unchanged list. DualListModel.KEEP_SELECTION mode will not change the right list at all when items are selected. This is the only mode which can result duplicated items to be selected. If that's what you want in your situation, this mode is the one you should use. You could disable the duplicate selection option by invoking {link #setAllowDuplicates(false)}.

DualList extends JideSplitPane, which makes users conveniently resize the width of either list.
