arrow keys change spin button value

["R. Alblas" <r alblas demon nl>]

In a drawable I want to use the arrow keys to scrol through a
picture. However, at the same time gtk uses the same arrow
keys to walk through buttons, and if a spin button is reached
the value is altered.
How can I switch off this behaviour?

I did send this question 1 month  ago, and got the answer to
let the key function return TRUE. But this doesn't work.

I use gtk 1.2.

Relevant code:

gboolean key_actions(GtkWidget *widget, GdkEventKey *event)
{
...
  return TRUE;              /* This should do it, but it doesn't! */
}


main()
{
  GtkWidget window;
...
  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

  gtk_signal_connect(GTK_OBJECT(window),"key_press_event",
                (GtkSignalFunc)key_press_event,NULL);

...
(add spin buttons to window etc.)
...
  gtk_main();
}
