You can use the following statements to allow
execution of the main loop for any pending events and
signals and can resume your loop again..

while( your_loop_is_required )
{
   while( gtk_events_pending() )
      gtk_main_iteration();

   your_custom_statements ;
}

For the sroping of the loop you can pass address of a
variable to both the callbacks and monitor the
variable in the loop.  Execute the loop until the
variable is TRUE and exit from the loop if it is
FALSE.

Now your job to stop the loop from another callback is
as simple as making the value of the variable FALSE.

Hope this Helps.
