Examples of java.beans.PropertyEditor.addPropertyChangeListener()

java.beans.PropertyEditor.addPropertyChangeListener()
Register a listener for the PropertyChange event. When a PropertyEditor changes its value it should fire a PropertyChange event on all registered PropertyChangeListeners, specifying the null value for the property name and itself as the source. @param listener An object to be invoked when a PropertyChangeevent is fired.

    System.err.println("Warning: Property \"" + name 
           + "\" has non-displayabale editor.  Skipping.");
    continue;
  }
  
  editor.addPropertyChangeListener(this);


      } catch (InvocationTargetException ex) {
  System.err.println("Skipping property " + name
         + " ; exception on target: "
         + ex.getTargetException());
