timer

Arguments: timer

This generic function is invoked to "fire" a timer whenever the timer is active and its interval has elapsed. The default timer method increments the timer's timer-count and then calls the timer's on-timer function if it has one. Methods could be added to the timer generic function by an application that wishes to modify the firing behavior of a whole timer subclass, rather than providing an on-timer function to each instance of that subclass.

See cg-timers.htm for more information on timers.
