All Implemented Interfaces:

Direct Known Subclasses:

public class ActivityPropertyEvent
extends IlvPropertyEvent
implements ActivityEvent

ActivityPropertyEvent is the superclass of all property aboutToChange and changed events fired by IlvActivity's. Basic support is provided for storing the property's old and new values, along with veto capabilities for aboutToChange events. Concrete subclasses should provide typesafe accessors for the property's values. For example:

  class ActivityFooEvent extends ActivityPropertyEvent
  {
    public ActivityFooEvent(IlvActivity activity,
                            Foo oldVal, Foo newVal,
                            boolean aboutToChangeEvent)
    {
      super(activity, oldVal, newVal, aboutToChangeEvent);
    }

    public Foo getOldFoo()
    {
      return (Foo)getOldValue();
    }

    public Foo getNewFoo()
    {
      return (Foo)getNewValue();
    }

    public void setNewFoo(Foo newVal)
    {
      setNewValue(newVal);
    }
  }
 

Interested ActivityListener's must register with the gantt data model to receive these events. IlvActivity does not handle direct listener subscriptions.
