Class SwtGraphPanelPopupMenuSource

java.lang.Object
  com.tensegrity.skeleton.swt.SwtGraphPanelPopupMenuSource

All Implemented Interfaces:

JPopupMenuSource, JPopupMenuSourceWithUpdateUI

public class SwtGraphPanelPopupMenuSource

extends java.lang.Object

implements JPopupMenuSourceWithUpdateUI

This class provides the popup menus for the drawing areas. Note that since the application frame only holds one instance of popup menu source shared among all the GraphPanels the destroy method overridden in this class does nothing. Override the destroyBeforeCreating() method instead in order to ensure that the UIMap does not get overloaded when doing Look And Feel switches.
