Class ThumbnailsPanelController

java.lang.Object
org.jpo.gui.ThumbnailsPanelController
All Implemented Interfaces:
NodeNavigatorListener, JpoDropTargetDropEventHandler
public class ThumbnailsPanelController extends Object implements NodeNavigatorListener, JpoDropTargetDropEventHandler
The ThumbnailPanelController manages a JPanel in a JScrollPane that displays a group of pictures in a grid of thumbnailControllers or ad hoc search results. Real pictures are shown as a thumbnail of the image whilst groups are shown as a folder icon. Each thumbnail has its caption under the image.

If the size of the component is changed the images are re-laid out and can take advantage of the extra space if there is some.
