Class ScrollableThumbnail
java.lang.Object
org.eclipse.draw2d.Figure
org.eclipse.draw2d.parts.Thumbnail
org.eclipse.draw2d.parts.ScrollableThumbnail
- All Implemented Interfaces:
IFigure
,UpdateListener
A scaled image representation of a Figure. If the source Figure is not
completely visible, a SelectorFigure is placed over the thumbnail
representing the viewable area and can be dragged around to scroll the source
figure.
