event% : class?
superclass: object%

An event% object contains information about a control, keyboard, mouse, or scroll event. See also control-event%, key-event%, mouse-event%, and scroll-event%.

( new event% [[time-stamp time-stamp]]) → ( is-a?/c event%)
time-stamp : exact-integer? = 0

See get-time-stamp for information about time-stamp.

( send an-event get-time-stamp) → exact-integer?

Returns the time, in milliseconds, when the event occurred. This time is compatible with times reported by Racket’s current-milliseconds procedure.

( send an-event set-time-stamp time) → void?
time : exact-integer?

Set the time, in milliseconds, when the event occurred. See also Racket’s current-milliseconds.

If the supplied value is outside the platform-specific range of time values, an exn:fail:contract exception is raised.
