-// Widget interface
-//
-// Widget is an abstract class that defines the API that should be implemented
-// by a native window in order to host a view hierarchy.
-//
-// Widget wraps a hierarchy of View objects (see view.h) that implement
-// painting and flexible layout within the bounds of the Widget's window.
-//
-// The Widget is responsible for handling various system events and forwarding
-// them to the appropriate view.
