All Implemented Interfaces:

ActivityEvent, Serializable

public class ActivityUserPropertyEvent
extends ActivityPropertyEvent

ActivityUserPropertyEvent is fired by an IlvGeneralActivity both before and after a user-defined property is modified. Immediately before a property is modified, an IlvGeneralActivity fires an aboutToChange ActivityUserPropertyEvent to all listeners registered with the Gantt data model. Listeners can modify or constrain the proposed property change by calling setNewValue(java.lang.Object). Alternatively, a listener can veto the proposed change by calling IlvPropertyEvent.veto(). If the property change is not vetoed, then IlvGeneralActivity will apply the change and fire a changed ActivityUserPropertyEvent to all listeners registered with the Gantt data model.

JViews 5.5
