Arguments: stream event-number button-state data frame-section
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. Argument list change: nc-event used to have six
arguments. It now accepts only five. The time (sixth) argument is no
longer passed because it was a performance drain and rarely if ever
used. If you need the time, use the function GetMessageTime.
See cg-events.htm for information about event handling in Common Graphics.
