public class IlvGeneralActivity
extends IlvSimpleActivity
implements IlvUserPropertyHolder

IlvGeneralActivity is an extension of IlvSimpleActivity that adds support for user-defined properties. IlvGeneralActivity fires an ActivityUserPropertyEvent both before and after a user-defined property is modified. Immediately before a property is modified, IlvGeneralActivity fires an aboutToChange ActivityUserPropertyEvent to all listeners registered with the Gantt data model. This gives the listeners an opportunity to constrain or veto the proposed property change. If the property change is not vetoed, then the change is applied and IlvGeneralActivity fires a changed ActivityUserPropertyEvent to all listeners registered with the Gantt data model.

IlvGeneralActivity predefines 6 properties that are inherited from its IlvSimpleActivity superclass. These predefined properties can be accessed through the getProperty(java.lang.String) and setProperty(java.lang.String, java.lang.Object) methods in the same manner as user-defined properties. However, the predefined properties fire specific event types. They do not fire ActivityUserPropertyEvents as described above for user-defined properties. The predefined events are shown in the following table:

Property	Value Type	Equivalent getXXX Method	Equivalent setXXX Method	Event Type
id	String	getID	setID	ActivityIDEvent
name	String	getName	setName	ActivityNameEvent
startTime	Date	getStartTime	setStartTime	ActivityTimeIntervalEvent
endTime	Date	getEndTime	setEndTime	ActivityTimeIntervalEvent
duration	IlvDuration	getDuration	setDuration	ActivityTimeIntervalEvent
timeInterval	IlvTimeInterval	getTimeInterval	setTimeInterval	ActivityTimeIntervalEvent

Since:

JViews 5.5
