## org.eclipse.swt.events
Interface HelpListener

All Superinterfaces:
  EventListener, org.eclipse.swt.internal.SWTEventListener

public interface HelpListener
extends org.eclipse.swt.internal.SWTEventListener

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.

  `HelpEvent`
