Interface HelpListener

All Superinterfaces:
EventListener
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface HelpListener extends EventListener
Classes which implement this interface provide a method that deals with the event that is generated when help is requested for a control, typically when the user presses F1.

After creating an instance of a class that implements this interface it can be added to a control using the addHelpListener method and removed using the removeHelpListener method. When help is requested for a control, the helpRequested method will be invoked.
