Interface SwingHandler

All Known Implementing Classes:

AbstractSwingHandler, BasicOptionHandler, BoundsHandler, LayoutHandler, MarginHandler, ModelHandler, PositionHandler, WindowHandler

public interface SwingHandler

SwingHandlers are used to implement the way each option annotation is handled. Because this class uses the ServiceManager as a general cache it is possible to add own annotations with own handlers.

This class is the top level handler in the generation process of every gui. It is called after the Component was initialized and all annotations were read.
