All Implemented Interfaces:

IDragRowRenderer, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class DefaultDragRowRenderer
extends javax.swing.JPanel
implements IDragRowRenderer

The default implementation of the IDragRowRenderer interface uses the IDragAndDropPolicy to determine whether the currently dragged timeline object can be dropped on the row. If the timeline object can not be dropped then the row will be covered with a semi-transparent gray rectangle. The renderer will only be used when the edit mode (see IEditModeController.EditMode) of the DragLayer is either CHANGE_NODE or CHANGE_NODE_AND_TIME_SPAN.
