In a program I am writing, I instantiate a series of randomly timed callbacks with add_periodic_callback(callback, random.random() * 150 ). Then, later, when a button is pushed I want to stop the periodic callbacks. I use something like this:
button_stop.on_click(stop_callbacks)
where the stop_callbacks callback, is just
curdoc().remove_periodic_callback(callback)
Unfortunately, this stop_callbacks callback only seems to work and stop the callbacks 1 every 3-4 times. It’s strange behavior. Can anyone help me out with this problem?
Each callback can be added only once (but if you were adding twice it should be throwing a ValueError I believe). That’s the only guess I have based on what you said… maybe you can make a minimal test case and post the runnable code?
