javax.media.jai.widget.ScrollingImagePanel
| ScrollingImagePanel | | public class ScrollingImagePanel extends ScrollPane implements AdjustmentListener,ComponentListener,MouseListener,MouseMotionListener(Code) | | An extension of java.awt.Panel that contains an ImageCanvas and
vertical and horizontal scrollbars. The origin of the ImageCanvas
is set according to the value of the scrollbars. Additionally, the
origin may be changed by dragging the mouse. The window cursor
will be changed to Cursor.MOVE_CURSOR for the duration of the
drag.
Due to the limitations of BufferedImage, only TYPE_BYTE of band
1, 2, 3, 4, and TYPE_USHORT of band 1, 2, 3 images can be displayed
using this widget.
This class has been deprecated. The source
code has been moved to the samples/widget
directory. These widgets are no longer
supported.
