A canvas panner is a window that provides a mechanism to visualize and manipulate a JCanvas object. Unlike the JPanner class, this class is only useful for a JCanvas. It has the advantage that it handles the infinite space metaphor of the canvas better than the JViewport, which implicitly assumes that a swing component represents a finite, predetermined area. This class contains a complete, scaled down rendition of all of the 'interesting things' contained in the canvas. The bounds of the visible portion of the canvas is visible on the panner as a red rectangle. Clicking or dragging within the JCanvasPanner centers the visible portion of the canvas at that point on the component, without zooming in or out. @author Steve Neuendorffer @version $Id: JCanvasPanner.java,v 1.21.4.1 2008/03/25 22:31:12 cxh Exp $
