There are 2 possibilities:

1) Organize your code so, that you can return from it from time to time
and use gtk_idle_add() to return to the operation. In this case you must
put all local variables that you want to keep their value into a separate
structure that is given to the idle function as an argument.

2) Every now and then, do:
	while (gtk_events_pending())
               gtk_main_iteration();

See GTK tutorial and GTK faq for more information.
