Package prefuse.controls Description

Control modules for incorporating interaction in prefuse Displays. Examples include clicking a node to make it the new focus, dragging nodes to change their position, and performing pan and zoom operations. To add one of these controls to a visualization, create a new instance of the desired control and register it using the Display.addControlListener(Control) method of the Display class. Custom Controls can easily be constructed by implementing the Control interface, or, more conveniently, by subclassing the ControlAdapter class.
