Interface ExpandListener

  • All Superinterfaces:
    EventListener, SWTEventListener
    All Known Implementing Classes:
    ExpandAdapter
    public interface ExpandListener
extends SWTEventListener
    Classes which implement this interface provide methods that deal with the expanding and collapsing of ExpandItems.

    After creating an instance of a class that implements this interface it can be added to a ExpandBar control using the addExpandListener method and removed using the removeExpandListener method. When a item of the ExpandBar is expanded or collapsed, the appropriate method will be invoked.
