FRED containing dialog-items??

[Marcus Specht <specht@cogpsy.uni-trier.de>]

I have a subclass of fred-window containing a fred-dialog-item and i want
to make the fred-dialog-item the active key-handler of the fred window.
Isn't that possible?
Every time i try to set the current key-handler of my fred-window with:
(set-current-key-handler "fred-window" "fred-dialog-item") and ask 
(current-key-handler "fred-window") i get "fred-dialog-item"
 
but all typing is handled by the fred-window !!!!!!!

Thanks
