Re: How to maintain responsiveness during long functions?

The ideal solution is to split up the working into small chunks and get an
idle function to take care of it.

The other solution is to call the following code during the working every
now and again:
  if (gtk_events_pending())

In general, I have found that the first solution runs faster and gives a
more responsive interface, but requires a bit more thinking to implement
correctly.  (It also has the advantage that it is easier to cancel the
thinking, if that is important).
