Examples of java.beans.VetoableChangeListener

java.beans.VetoableChangeListener
A VetoableChange event gets fired whenever a bean changes a "constrained" property. You can register a VetoableChangeListener with a source bean so as to be notified of any constrained property updates.

    _app = app;
    _uiFactory = (UserInterfaceFactory)getUserInterfaceFactory();
    _uiFactory.setDriversListInternalFrame(this);




      addVetoableChangeListener(new VetoableChangeListener()
      {
         public void vetoableChange(PropertyChangeEvent evt) throws PropertyVetoException
         {
            if(JInternalFrame.IS_CLOSED_PROPERTY.equals(evt.getPropertyName()) && Boolean.TRUE.equals(evt.getNewValue()))
            {
