[Haskell-beginners] gtk2hs and threadDelay

Thanks for the quick answers. I dont really know, what timer functions there are, I googled "timing, scheduling, delaying in haskell", but the only function I found, was threaddelay. How did you mean "adding a timer"? On the other side, I checked Graphics.UI.Gtk.Gdk.drawWindowProcessUpdates. I guess, I should use this in the function, where I draw something, and wait, and draw something else, and I should put it between the two drawing steps to get an immediate update. If I do so, the drawing gets blocked again, and nothing happens for some second, and then everything is drawn at the same time. Sorry, I m a very beginner at this topic.
