Pb with CLIST and Pixmaps ...

[Quentin Delamarre <Quentin Delamarre sophia inria fr>]

Hi,

I would like to create a CLIST with 2 columns: one for some
text, and one for pixmaps.

The problem I have is that the pixmaps are not visible !

The pixmap file is OK because I used it for an other GTK program
that works fine and that doesn't use CLIST. I'm using
GTK 1.2.2.

I couldn't find any clue in the tutorial, in the reference guide
or in the gtk-list archive, so please HELP !!!

This is the program:
The first function open the pixmap file and return the pixmap
widget. And the second one creates a window with a clist in it.

When I run it, the window opens, the clist is shown with the
titles and the text, but no pixmap ! I get no error and no
warning.
