Re: Q: How do I enable/disable a timed callback during runtime?

[Nickolai Dobrynin <dobrynin cs uwm edu>]

Mirco,

You can disable the time-out callback at any time by having it return false,
instead of true.  Once you do this, it will not be called again.  To re-activate
the callback, you would probably need to re-connect it using the technique
you've been described in the previous two posts.


Regards,

Nickolai
