Class ContextMenuAdapter

java.lang.Object

com.datagis.terraexplorer.menu.ContextMenuAdapter

All Implemented Interfaces:

ContextMenuListener, EventListener

public class ContextMenuAdapter
extends Object
implements ContextMenuListener

An abstract adapter class for receiving context menu events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a context menu listener and override the methods for the context menu events of interest. (If you implement the ContextMenuListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)

Create a listener object using the extended class and then register it with the ContextMenu object obtained from the Map3DWindow object using its addContextMenuListener method.
