public class Overview

extends Graph2DView

implements PropertyChangeListener

This is a specialized View which acts as Overview. The View displays always the entire Graph. Additionally it highlights the region that the associated Graph2DView currently displays.

The OverView has a specialized ViewMode associated with it that allows to change the viewport of the associated Graph2DView by dragging the highlighted area.
