edu.uci.ics.jung.visualization.control.PickingGraphMousePlugin
public class PickingGraphMousePlugin
PickingGraphMousePlugin supports the picking of graph elements with the mouse. MouseButtonOne picks a single vertex or edge, and MouseButtonTwo adds to the set of selected Vertices or Edges. If a Vertex is selected and the mouse is dragged while on the selected Vertex, then that Vertex will be repositioned to follow the mouse until the button is released.
