All Implemented Interfaces:

ActivityEvent, Serializable

public class ActivitiesRemovedEvent
extends IlvHierarchyNodeChildEvent<IlvActivity>
implements ActivityEvent

ActivitiesRemovedEvent is used to notify listeners when children have been removed from a common parent activity in the tree of activities managed by an IlvGanttModel. The child activities must be siblings and direct descendents (not grandchildren) of the specified parent activity. A listener can obtain the parent activity by calling getActivity().

Constructor Detail

ActivitiesRemovedEvent

public ActivitiesRemovedEvent(IlvGanttModel model,
                              IlvActivity parent,
                              List<? extends IlvActivity> children,
                              int[] childIndices)

Constructs a new ActivitiesRemovedEvent generated by the specified data model that can be used to notify listeners when child activities have been removed from a common parent.

Parameters:

model - The data model where the event originated.

parent - The parent activity that has had children removed. If the deletion being reported is the data model's root activity, parent should be null, children should be a single element list containing the root activity, and childIndices should be a single element array with childIndices[0]=0.

children - The list of child IlvActivity's that have been removed. The activities do not have to be presorted, but must be arranged in parallel with childIndices. In other words, childIndices[i] must contain the index that activity (IlvActivity)children.get(i) had before it was removed.

childIndices - An int array that specifies the index values that the child activities had before they were removed. The indices do not have to be presorted, but must be arranged in parallel with children.

public IlvActivity getActivity()

Specified by:

getActivity in interface ActivityEvent

Returns:
