problem to change the background color of a scrolled window

[karim bernardet <bernardet karim wanadoo fr>]

Hi everybody !

I have a scrolled window with a table :

Window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

  Scr = gtk_scrolled_window_new(NULL, NULL);
  gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(Scr),
                                 GTK_POLICY_AUTOMATIC,
                                 GTK_POLICY_AUTOMATIC);

gtk_container_add(GTK_CONTAINER(Window), Scr);

gtk_widget_show (Scr);

table=gtk_table_new (rows,columns,homogeneous);

...

gtk_scrolled_window_add_with_viewport (GTK_SCROLLED_WINDOW (Scr),
table);

But the background is grey and i would like to change it. How can i do
that ?

thanks a lot for your help !
