- class vispy.app.timer.Timer(interval='auto', connect=None, iterations=- 1, start=False, app=None)#
Timer used to schedule events in the future or on a repeating schedule.
- intervalfloat | ‘auto’
Time between events in seconds. The default is ‘auto’, which attempts to find the interval that matches the refresh rate of the current monitor. Currently this is simply 1/60.
- connectfunction | None
The function to call.
Number of iterations. Can be -1 for infinite.
Whether to start the timer.
- appinstance of vispy.app.Application
The application to attach the timer to.
- property app#
Timer is based on this vispy Application instance.
Alias for self.events.timeout.connect().
Alias for self.events.timeout.disconnect().
- property elapsed#
- property interval#
- property native#
Timer is based on this native timer
- property running#
- start(interval=None, iterations=None)#
Start the timer.
A timeout event will be generated every interval seconds. If interval is None, then self.interval will be used.
If iterations is specified, the timer will stop after emitting that number of events. If unspecified, then the previous value of self.iterations will be used. If the value is negative, then the timer will continue running until stop() is called.
If the timer is already running when this function is called, nothing happens (timer continues running as it did previously, without changing the interval, number of iterations, or emitting a timer start event).
Stop the timer.
