I thought this was a little off the mark; gdk is meant to be a drawing
toolkit, and it seems to me that event loops are a widget toolkit kind
of thing. But being a self-confessed newbie to gtk, I decided to have a
look in gdk.h to see if I was off track, and I spotted the real cause of
my problem.

There is a function gdk_flush(). Putting this in after all of my drawing
code and before the sleep() worked wonders. It has been sooo long since
I did any Xlib stuff that I didn't even think of the need to flush the
connection to the X server.

Thanks anyway for the responses.
