ilog.views.gantt.event.GanttModelChangedEvent

All Implemented Interfaces:

Serializable

public class GanttModelChangedEvent
extends IlvPropertyEvent

GanttModelChangedEvent is fired by a chart both before and after the gantt model has been set. Note, that this event does not indicate that some aspect of the model has changed. Rather, it indicates that the data model has been replaced by an entirely new one.

Constructor Detail

GanttModelChangedEvent

public GanttModelChangedEvent(Object source,
                              IlvGanttModel oldModel,
                              IlvGanttModel newModel,
                              boolean aboutToChangeEvent)

Constructs a new GanttModelChangedEvent generated by the specified source and with the specified old and new data models.

Parameters:

source - Where the event originated.

oldModel - The previous data model.

newModel - The new data model.

aboutToChangeEvent - true if this is an aboutToChange event or false if this is a changed event.

Method Detail

getGanttConfiguration

public IlvGanttConfiguration getGanttConfiguration()

Returns the Gantt configuration where this event originated.

Returns:

The IlvGanttConfiguration where this event originated or null if the source of the event was not a Gantt configuration.

getOldGanttModel

public IlvGanttModel getOldGanttModel()

Returns the gantt configuration's old data model. If this is an aboutToChange event, then this will be the same as the configuration's current data model since the change has not actually occurred yet. If this is a changed event, this will be the configuration's data model prior to the current modification being reported.

Returns:

The old IlvGanttModel.

getNewGanttModel

public IlvGanttModel getNewGanttModel()

Returns the gantt configuration's new data model. If this is an aboutToChange event, then this is will be the configuration's proposed data model. If this is a changed event, this will be the configuration's new data model which is being reported.

Returns:

The new IlvGanttModel.

setNewGanttModel

public void setNewGanttModel(IlvGanttModel ganttModel)

Sets the gantt configuration's proposed new data model. This method only has meaning if this is an aboutToChange event. By using this method, a listener can constrain changes to the configuration's data model.

Parameters:

ganttModel - the data model
