Package org.eclipse.swt.events

Interface ControlListener

  • All Superinterfaces:
    EventListener, SWTEventListener
    All Known Implementing Classes:
    AnnotationBarHoverManager.Closer, ControlAdapter
    public interface ControlListener
extends SWTEventListener
    Classes which implement this interface provide methods that deal with the events that are generated by moving and resizing controls.

    After creating an instance of a class that implements this interface it can be added to a control using the addControlListener method and removed using the removeControlListener method. When a control is moved or resized, the appropriate method will be invoked.

        Parameters:
        e - an event containing information about the move

      • controlResized

        void controlResized​(ControlEvent e)
        Sent when the size (width, height) of a control changes.
        Parameters:
        e - an event containing information about the resize

      • controlMovedAdapter

        static ControlListener controlMovedAdapter​(Consumer<ControlEvent> c)
        Static helper method to create a ControlListener for the controlMoved(ControlEvent e)) method, given a lambda expression or a method reference.
        Parameters:
        c - the consumer of the event
        Returns:
        ControlListener
