This class encapsulates the data related to all events in a Cocoa application. NSEvent objects are dispatched by NSApplication to the appropriate receiver using the method sendEvent:. Both key and mouse events are represented by NSEvent. All classes that wish to respond to events must inherit from NSResponder.
