Interface VerifyListener

  • All Superinterfaces:
    EventListener, SWTEventListener
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    public interface VerifyListener
    extends SWTEventListener
    Classes which implement this interface provide a method that deals with the events that are generated when text is about to be modified.

    After creating an instance of a class that implements this interface it can be added to a text control using the addVerifyListener method and removed using the removeVerifyListener method. When the text is about to be modified, the verifyText method will be invoked.
