Well, I'm just back from the pub but I'll try to help anyway... The only way I got a \
pixmap into a clist was by looking at the code in gtkmail (from another developer on \
this list). I came up with the following code:

in foo.h:
Gtk::ImageLoader *il;

in constructor:
il = new Gtk::ImageLoader("pixmap.xpm");

somewhere else:
cell( row, col ).set_pixmap( il->pix(), il->bit() ); 

I am very tired now and I don't know if it was this you wanted to know but anyway...

I never got a pixmap into a clist directely, I had to go through a Gtk::ImageLoader. \
I don't know if this is the right way to do it but it works.
