public void setLists(javax.swing.JList ul,
                     javax.swing.JList dl,
                     javax.swing.JList wl)

getListModels

public ChangeableListModel[] getListModels()

getUnwantedElements

public java.util.List getUnwantedElements()

getWantedElements

public java.util.List getWantedElements()

setAndSelectable

public void setAndSelectable(boolean b)

isAndSelectable

public boolean isAndSelectable()

setUnwantAnd

public void setUnwantAnd(boolean b)

isUnwantAnd

public boolean isUnwantAnd()

setWantAnd

public void setWantAnd(boolean b)

isWantAnd

public boolean isWantAnd()

moveElements

protected void moveElements(int[] fromindices,
                            int fromidx,
                            int toidx)

Moves elements from one list to another. Does the main work of this object. Moves Elements between lists based on the selection of the source list. The used methods of the ChangeableListModel interface take care of handling the selection of the target list and right ordering etc.

trimContent

public void trimContent(java.util.List v)

Extends or shrinks the content of the three base models with respect to the given List. All three list models are trimmed to the external List. After that, the remaining elements of the List are appended to the dontcare list. After this, the UnwantWantSelector shows exactly the elements of the given List.
