How to change the label on a menu.

["J. Davison de St. Germain" <dav cs utah edu>]

Hi,

  Can someone tell me how to change the label on a menu item in GTK?
I've created the menu with a label (say: "Turn on Light") and when a
user selects it, I wish to change the lable (to say: "Turn off
Light").  I've looked at the API and can not find an applicable
function.  I've also looked at the source code and it appears that the
pointer to the label is "lost" and thus it might not be possible to 
do this.  Any help is greatly appreciated.

     Thanks,
            Dav
