Interface TraverseListener

  • 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.

    @FunctionalInterface
    public interface TraverseListener
    extends SWTEventListener
    Classes which implement this interface provide a method that deals with the events that are generated when a traverse event occurs in a control.

    After creating an instance of a class that implements this interface it can be added to a control using the addTraverseListener method and removed using the removeTraverseListener method. When a traverse event occurs in a control, the keyTraversed method will be invoked.

      • keyTraversed

        void keyTraversed​(TraverseEvent e)
        Sent when a traverse event occurs in a control.

        A traverse event occurs when the user presses a traversal key. Traversal keys are typically tab and arrow keys, along with certain other keys on some platforms. Traversal key constants beginning with TRAVERSE_ are defined in the SWT class.

        Parameters:
        e - an event containing information about the traverse
