NewRelationAction

public NewRelationAction()

Create an action that creates a new relation.

NewRelationAction

public NewRelationAction(java.lang.String[][] iconRoles)

Create an action that creates a new relation.

Parameters:

iconRoles - A matrix of Strings, where each element consists of two Strings, the absolute URL of the icon and the key that represents the role of the icon. The keys are usually static fields from this class, such as GUIUtilities.LARGE_ICON, GUIUtilities.ROLLOVER_ICON, GUIUtilities.ROLLOVER_SELECTED_ICON or GUIUtilities.SELECTED_ICON. If this parameter is null, then the icon comes from the calling getNodeRenderer() on the WithIconGraphController._portController.
