Subject: [Lablgtk] Background image

Hi there,

Sorry for this very basic question, but I'm at a loss...


Context:
I have a legacy image representing an approximate map.

I want to superimpose a grid on it, and put circles of different size/color
in the individual squares based on some text data I'll read in a file.

Then, I want to be able to change circles of an individual square
simply by clicking on it (thus, cycling through the different circles
available).

Problem:
I'm trying to adapt the "scribble.ml" example from
http://plus.kaist.ac.kr/~shoh/ocaml/lablgtk2/lablgtk2-tutorial/a2692.html#AEN2697

I thought it'd be a good starting point, since this code draws little
black squares
inside a window. I figured adding my background image would do the trick...
I managed to make my background image visible (by adding a call to
"drawing#pixbuf"
in the "expose" function), but then I don't see the little black squares!

All other fiddlings I tried were unsuccessful at even making appear my
background
image!

Any advice?


Thanks in advance.

--Serge
