Class DirtyManager

java.lang.Object

org.posper.data.user.DirtyManager

All Implemented Interfaces:

ActionListener, PropertyChangeListener, EventListener, ChangeListener, DocumentListener, ListSelectionListener, TableModelListener, TreeSelectionListener

public class DirtyManager
extends Object
implements DocumentListener, ChangeListener, ActionListener, PropertyChangeListener, TableModelListener, ListSelectionListener, TreeSelectionListener

The DirtyManager supervises form fields and detects if a field has been edited. Additionally, mandatory fields can be defined by letting the label end with an asterisk. For this to work the form must use the checkField method in place of addDirtyListener. DirtyManager will then track these fields for completeness. Completeness can be checked with isComplete().
