Here goes an adaptation of a function I have to set an image background to a
GtkTextView -- it should work, but if it doesn't, that's the idea. You must
call this after the GtkTreeView widget has been realized. So, if you want to
set it right at start, you have to delay it with:
g_signal_connect (G_OBJECT (tree_view), "realize",
G_CALLBACK (set_help_background_cb), NULL);
(and call it on a "void set_help_background_cb (GtkWidget *, gpointer)")
«
void gtk_treeview_set_background (GtkTreeView *view, const char *image)
{
g_return_if_fail (GTK_WIDGET_REALIZED (GTK_WIDGET (view)));
GdkWindow *window = gtk_tree_view_get_bin_window (view);
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);
}

Cheers,
