class Gtk_Widget

Public member index
... Signal_proxyN<gint,widgettype,GdkEventAny*> destroy_event; 

Protected member index
... virtual gint destroy_event_impl(GdkEventAny*); 

Similar functions are for "delete". What are these "destroy" functions
for ?

I'm a little bit confused as GTK+ tutorial uses a lot the destroy event,
while, as I can see till now, GTK-- preferes delete and doesn't call
delete_event_impl at all. 

Can you please detail a bit this problem ? (Or tell me the mane of the
thread you've discussed this in ?

Thanks,
