## nc-event

Arguments: stream event-number button-state data frame-section

This generic function is obsolete and kept for backward compatibility only. Starting in version 5.0, events are handled somewhat differently than in 3.0.2. Instead of specializing nc-event, you should specialize the new generic function named after the message, such as `nc-right-mouse-down` and `nc-mouse-moved`. These were only constants in 3.0.2 (corresponding to the message argument to nc-event) but they are now constants and generic-functions. nc-event is still called, as in 3.0.2, but it simply dispatches to the appropriate new function. All these functions take the same arguments as nc-event except the event-number argument.

See cg-events.htm for information about event handling in Common Graphics.
