public class GraphZoomScrollPane
extends JPanel

GraphZoomScrollPane is a Container for the Graph's VisualizationViewer and includes custom horizontal and vertical scrollbars. GraphZoomScrollPane listens for changes in the scale and translation of the VisualizationViewer, and will update the scrollbar positions and sizes accordingly. Changes in the scrollbar positions will cause the corresponding change in the translation component (offset) of the VisualizationViewer. The scrollbars are modified so that they will allow panning of the graph when the scale has been changed (e.g. zoomed-in or zoomed-out). The lower-right corner of this component is available to use as a small button or menu. samples.graph.GraphZoomScrollPaneDemo shows the use of this component.
