Class CSHManager

java.lang.Object
oracle.help.CSHManager

public class CSHManager

extends java.lang.Object

CSHManager is a helper class to manage Help with in an application. This class is useful for applications implementing context-sensitive help.

The CSHManager class provides multiple flavors of addComponent() to register objects for which help should be shown automatically upon receiving the F1 KeyPress event or a right-mouse pressed MouseEvent. Applications can also show help for objects explicitly by calling showHelpForComponent .

Applications in general should create only one instance of this class at application start up and share that instance. Applications having a single help Book can register their book as the DefaultBook. DefaultBook is used as the help book when no book is specified at object registration time.
