i added background image to gtktreeview using
g_signal_connect (G_OBJECT (G_ContactList), "realize",
G_CALLBACK (contactlist_background_cb), NULL);
void contactlist_background_cb (GtkWidget *treeview, gpointer user_data)
{

GdkWindow *window = gtk_tree_view_get_bin_window (view);
gchar *image="background.bmp";
if (!image) {
gdk_window_clear (window);
return;
}

GError *error = 0;
GdkPixbuf *pixbuf = gdk_pixbuf_new_from_file (image, &error);
if (!pixbuf) {
g_warning ("could not open background image: '%s'"
" - %s", image, error->message);
return;
}

GdkPixmap *pixmap;
gdk_pixbuf_render_pixmap_and_mask_for_colormap (pixbuf,
gdk_drawable_get_colormap (GDK_DRAWABLE (window)), &pixmap, NULL, 0);
g_object_unref (G_OBJECT (pixbuf));

gdk_window_set_back_pixmap (window, pixmap, FALSE);

}

Every widget has a GtkStyle member called style. Use widget->style->bg_pixmap[] to specify a background pixmap. You can specify a background pixmap for any of the five widget states. Check it out here:

You don't need a function ... just edit the variable.
