Can change appearance with gtk_handle_box_set_shadow_type

[Christian Seberino <seberino spawar navy mil>]

I'm trying to change the appearance of a handle box
(that happens to hold a menu bar).


Here is my line that doesn't seem to do anything...

   gtk_handle_box_set_shadow_type(GTK_HANDLE_BOX(MenuBar::handleBox), GTK_SHADOW_ETCHED_IN);

Is this correct and why does no value for last argument
seem to make a difference?
