23.18 java.beans.PropertyEditorSupport (JDK 1.1)

The PropertyEditorSupport class is a trivial implementation of the PropertyEditor interface. It provides "no-op" default implementations of most methods, so that you can can define simple PropertyEditor subclasses that only override a few required methods.

In addition, PropertyEditorSupport defines working versions of addPropertyChangeListener() and removePropertyChangeListener(), along with a firePropertyChange() method that sends a PropertyChangeEvent to all registered listeners. PropertyEditor classes may choose to instantiate a PropertyEditorSupport object simply to handle the job of managing the list of listeners. When used in this way, the PropertyEditorSupport object should be instantiated with a source object specified, so that that source object can be used in the PropertyChangeEvent objects that are sent.

public class PropertyEditorSupport extends Object implements PropertyEditor {
    // Protected Constructors
            protected PropertyEditorSupport();
            protected PropertyEditorSupport(Object source);
    // Public Instance Methods
            public synchronized void addPropertyChangeListener(PropertyChangeListener
            public synchronized void addPropertyChangeListener'u'listener);  // From PropertyEditor
            public void firePropertyChange();
            public String getAsText();  // From PropertyEditor

            public void paintValue(Graphics gfx, Rectangle box);  // From PropertyEditor
            public synchronized void removePropertyChangeListener(PropertyChangeListener
            public synchronized void removePropertyChangeListener'u'listener);  // From PropertyEditor
