Changing cursor in GtkTextView

[Michael K <vk2bea yahoo com>]

I'm trying to change the cursor in a GtkTextView but with no success.

I have a signal that is being triggered 

g_signal_connect_after( View->Information, "realize",

                      (GCallback) on_TextViewRealize, userData );

calling this callback on the GtkTextView's creation

static void

on_TextViewRealize(GtkTextView *textView,  void *userData)

{

GdkCursor *helpCursor = gdk_cursor_new_from_name ( gtk_widget_get_display( GTK_WIDGET(textView) ), "help");

    gdk_window_set_cursor ( gtk_text_view_get_window ( GTK_TEXT_VIEW(textView), GTK_TEXT_WINDOW_TEXT ), helpCursor );

    if (helpCursor)

          g_object_unref (helpCursor);

}

but I see no change ???!!!  Can anyone help ?
