  com.alveole.studio.web.designer.graph.CustomLayout

All Implemented Interfaces:

edu.uci.ics.jung.utils.ChangeEventSupport, edu.uci.ics.jung.visualization.Layout, edu.uci.ics.jung.visualization.LayoutMutable, edu.uci.ics.jung.visualization.SettableVertexLocationFunction, edu.uci.ics.jung.visualization.VertexLocationFunction

public class CustomLayout
extends java.lang.Object
implements edu.uci.ics.jung.visualization.Layout, edu.uci.ics.jung.utils.ChangeEventSupport, edu.uci.ics.jung.visualization.SettableVertexLocationFunction, edu.uci.ics.jung.visualization.LayoutMutable

This class is a custom settable layout. This is a simple implementation of a Jung layout. It embeds a native Jung implementation layout, but enables to change node positions and to save them into project UI preferences.
