Interface TreeListener

  • All Known Implementing Classes:

    public interface TreeListener
    Classes which implement this interface provide methods that deal with the expanding and collapsing of tree branches.

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