- 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 SWTEventListenerClasses 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
addHelpListenermethod and removed using the
removeHelpListenermethod. When help is requested for a control, the helpRequested method will be invoked.
