All Implemented Interfaces:

IDragInfoRenderer, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, javax.swing.border.Border

public class DefaultDragInfoRenderer
extends javax.swing.JPanel
implements IDragInfoRenderer, javax.swing.border.Border

The default drag info renderer expects the IDragInfoPolicy that is currently being used to return an object that can be serialized via a simple call to Object.toString(). The renderer contains a text area, which will display the serialized object. The renderer additionally features a label at its top, which will use the currently installed ILabelPolicy to lookup a title via the LabelType.DRAG_INFO_TITLE value.

1.0
