public GanttEntryRelationEvent(Object source)

GanttEntryRelationEvent

public GanttEntryRelationEvent(GanttEntryRelationModel<?> source)

Creates a GanttEntryRelationEvent. The only place this constructor is called is when fireGanttEntryRelationChanged method is called in AbstractGanttEntryRelationModel. It means the gantt entry relation changed so much that it'd better if the listeners get the relations from the model from scratch. The type of the event in this case is undefined.

Parameters:

source - the source which is GanttEntryRelationModel.

GanttEntryRelationEvent

public GanttEntryRelationEvent(GanttEntryRelationModel<?> source,
                               int type)

Creates a GanttEntryRelationEvent. The only place this constructor is called is when fireGanttEntryRelationCleared method is called in AbstractGanttEntryRelationModel. The type is REMOVE in this case.

Parameters:

source - the source which is GanttEntryRelationModel.

GanttEntryRelationEvent

public GanttEntryRelationEvent(GanttEntryRelationModel<?> source,
