All Implemented Interfaces:

Serializable

Enclosing class:

IlvSubGraphRenderer

public static class IlvSubGraphRenderer.ExpandCollapseInteractor
extends IlvObjectInteractor

ExpandCollapseInteractor is the object interactor that is set on subgrapher nodes by the IlvSubGraphRenderer. This interactor toggles the expanded/collapsed state of the node.

This class is public only to allow saving in an IVL file the contents of a grapher associated with an SDM engine and containing expandable nodes.

Note that, when read from an IVL file, this interactor is not functional: it works only when it has been created by the expand/collapse renderer.

Since:

JViews 5.0
