Strange combo box

[ramare <Olivier Ramare univ-lille1 fr>]

Dear all,

   I have a smmoth combo_box, created with    the_one = 
gtk_combo_box_new_text();
   I fill it with       gtk_combo_box_append_text( GTK_COMBO_BOX( 
the_one ),  nom);
And what I get is indeed a combo_box, but, but ....
  All items are on alist (that's normal)
  The background of this list is grey (who controls that ??)
  The first place/characters/place of this background is dark grey

 That's exactly how KDE or gnome displays it menus, the firts place being
used for a small icon. So some questions :
 -- it seems gtk_combo_box_append_text() uses a stock_item but how to
     make it change ?? (That's a wild guess and I barely understand 
what I'm
     writing ...)
 -- how to introduce an icon if I wanted to ?

Many thanks in advance !
Best,
Amities,
               Olivier
