aplication to yield for processing of events

[Konstantin L Kouptsov <klk206 panix com>]

In my Gtkmm-2.0 application I have a very busy loop that performs 
calculations and that takes quite a while. In the meantime, I would like 
my program to be able to process events like resizing, redraw, button 
presses etc. What is the way to do that (I don't seem to find anything 
in the docs).

for(...)
{
	read data from file
	do calculation

	yield to process events <-???????????????????
}
