Arguments: timer
This function returns the value of the on-timer event property of the
argument timer. The value should be a function
object or a function name (a symbol naming a function). The function
is invoked after timer's interval has elapsed (assuming that the
default timer
method has not been overridden). The function should take a single
argument, which is the timer itself. Its returned values are not
used. The default value is nil
, and so a
timer will not do anything when its interval has elapsed unless it is
given a custom on-timer function (or a timer method is added for
it).
An on-timer
function can be specified with the :on-timer
initarg when creating a timer
instance with make-instance and setf can be used with on-timer to set or change the
on-timer function
of a timer.
See cg-timers.htm for more information on timers. See cg-events.htm for information about event handling in Common Graphics.
