Class EnhancedListModel<T>

java.lang.Object

javax.swing.AbstractListModel<E>

javax.swing.DefaultListModel<T>

com.iamsoft.util.ui.EnhancedListModel<T>

Type Parameters:

T - The type of the elements of this model.

All Implemented Interfaces:

Reorderable, ReorderableListModel<T>, Serializable, ListModel<T>

Direct Known Subclasses:

UndoableListModel

public class EnhancedListModel<T>
extends DefaultListModel<T>
implements ReorderableListModel<T>

Allow user to move items up/down within list. List models really should be generified.

Constructor Detail

EnhancedListModel

public EnhancedListModel()

EnhancedListModel

public EnhancedListModel(Collection<? extends T> pContents)

Method Detail

isEventFiringEnabled

protected boolean isEventFiringEnabled()

ListModelEvents are fired if this is true.

setEventFiringEnabled

protected void setEventFiringEnabled(boolean pEventFiringEnabled)

isEventFiringEnabled()

moveAll

public void moveAll(int[] pIndices,
                    EnhancedListModel.Direction pDir)

Shifts elements at specified locations in specified direction. One event is fired with indices determined by range of updates. Behavior undefined if indices are duplicated or out of range.

Specified by:

moveAll in interface Reorderable

moveAll

public void moveAll(Collection<?> pObjects,
                    EnhancedListModel.Direction pDir)

Move specified objects up or down. Behavior undefined if objects in collection are duplicated.

move

public void move(Object pObject,
                 EnhancedListModel.Direction pDir)

Move specified object up or down.

getIndices

public int[] getIndices(Collection<?> pColl)

Any elements not present in list marked with -1.

Returns:

int array with same size of Collection.

addAll

public void addAll(Collection<? extends T> pObjects)

Add all elements in a collection. Fires a single event.

insertAll

public void insertAll(Collection<? extends T> pObjects,
                      int pIdx)

Inserts all elements in a collection. Fires a single event.

removeAll

public void removeAll(int[] pIndices)

Remove specified indices. Contiguous ranges are removed as a batch. This method minimizes event notifications rather that execution time. Behavior undefined if indices are repeated or out of range.

removeAll

public boolean removeAll(Collection<?> pColl)

Remove all elements in a collection. Minimizes number of events rather than execution time. Behavior undefined if duplicate elements contained within argument collection.

Returns:

true if list is updated.

toArray

public Object[] toArray(Object[] pType)

fireContentsChanged

public void fireContentsChanged(Object pSrc,
                                int pIdx0,
                                int pIdx1)

TODO: Protect method.

Overrides:

                                 int pIdx0,
                                 int pIdx1)

Overrides:

Overrides:
