public class DefaultMultiDragAndDropCommand
extends AbstractDragAndDropCommand

A command that moves a given timeline object from one tree / hierarchy node to another. Additionally the timeline object's time span can be changed at the same time. This command can only be used in situations where the model is an instance of DefaultGanttChartModel, the old and the new tree node implement the IGanttChartNode interface, and the timeline object implements the ITimelineObject interface.
