Keep in mind that terminate will not only stop the threads execution for later 
restart/continue, it will really terminate the threads execution the hard way.

Use a variable (probably some bool) to check in your threads execution-loop 
and change this variable from the outside. Make the variable volatile so the 
compiler doesn't optimize access to that variable.
Maybe you could also use a mutex which the gui locks when the threads should 
pause and the thread checks for getting the lock (for a short time, otherwise 
you cant lock it from the gui) on each execution-loop.

Have fun,

Arnold
