Hi Tristan

Yes, I am trying to prevent the delete-event signal from propagating  
further by implementing the following

def delete(...):
        print "Don't delete"
        return True

window.connect ("delete-event",delete)

of course in glade, I connect the callback in the GUI, but the  
function is the same. Now in theory the return value of true should  
stop delete-event from propagating further, but it doesn't. And I have  
tried every variation, such as on destroy, destroy-event, returning  
False, gtk.TRUE, gtk.FALSE.

The only thing I discovered is that it has something to do with the  
run() function which interferes with how the delete-event works
