Examples of org.eclipse.swt.events.HelpListener

org.eclipse.swt.events.HelpListener
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.
