Nested Class Summary

Nested Classes
Modifier and Type	Class and Description
`static interface`	`VisualizationViewer.GraphMouse` a convenience type to represent a class that processes all types of mouse events for the graph
`protected class`	`VisualizationViewer.GraphMouseImpl` this is the original GraphMouse class, renamed to use GraphMouse as the interface name, and updated to correctly apply the vv transform to the point point
`static interface`	`VisualizationViewer.Paintable` an interface for the preRender and postRender
`static interface`	`VisualizationViewer.ToolTipListener` The interface for the tool tip listener.
`protected static class`	`VisualizationViewer.ToolTipListenerWrapper` used internally to wrap any legacy ToolTipListener implementations so they can be used as a ToolTipFunction
`protected class`	`VisualizationViewer.VisualizationListener` VisualizationListener reacts to changes in the size of the VisualizationViewer.
