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.

ControlAdapter, ControlEvent
