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

[Armin Burgmeier <armin arbur net>]

sigc::connection conn = 
Glib::signal_timeout(100).connect(sigc::ptr_fun(&on_timeout) );

to connect your signal handler to the timeout signal. Then you may just 
use conn.disconnect() to remove the connection.
