How to call a function using EventQueue, but then also be able to cancel it?

I haven't used EventQueue before in any language, so this is new to me and the documentation is inefficient for me to be able to know if it is useful for what I want to do.

I would like to call a function every set amount of time, but then be able to also cancel that function.

So I would like to do something like this:

queue.call_every(period, myOwnFunction(z,x) );   //call this function every period. 
queue.dispatch();                              //To make it run I would need this?

if (exitEvt == 1) {                              //if certain variable in main() program is set, the event should terminate at next available opportunity
queue.break_dispatch();             //this should kill off my event, or should cancel() be used here instead..?
}

Would this approach work? How do I 'call_every' a function?

I would also preferably want to then change the function the queue is calling after stopping the dispatch, so instead of myOwnFunction calling with parameters z and x, it would now be set up to call with parameters a and b, and so I can then dispatch it again after making that change.
