Class TransformingListModel

com.sas.swing.models.TransformingListModel

All Implemented Interfaces:

com.sas.beans.PropertyChangeSource, java.io.Serializable, java.util.EventListener, javax.swing.event.ListDataListener, javax.swing.ListModel

Direct Known Subclasses:

TransformingComboBoxModel

public class TransformingListModel
implements javax.swing.event.ListDataListener, com.sas.beans.PropertyChangeSource

TransformingListModel is a model that is used for instances of javax.swing.JList that can use transforms derived from com.sas.util.transforms.TransformInterface.

The TransformingListModel creates a new default model which is set to be a javax.swing.DefaultListModel to be used as the model for the list. No default transform is set so no transformation will take place on the items in the list unless a transform is provided.
