Interface ContextMenuListener

All Superinterfaces:

EventListener

All Known Implementing Classes:

ContextMenuAdapter

public interface ContextMenuListener
extends EventListener

The listener interface for receiving context menu events. The class that is interested in processing a context menu event either implements this interface (and all the methods it contains) or extends the abstract ContextMenuAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with the ContextMenu using the addContextMenuListener method. When the context menu is requested by the user (by pressing the "right" mouse key), showing or hidden, the relevant method in the listener object is invoked, and the ContextMenuEvent is passed to it.
