public class InteractiveViewMode
extends ViewMode

A ViewMode for interactive input scenarios. This class provides blocking methods such as getClickedNode that allow interactive processing of view based input events. The caller of such a method blocks until a user clicks on a node, etc. The caller of the blocking query methods may not live in the same AWT thread that provides coordinates to this mode.
