After searching around in the headers and docs I found this:

http://www.enlightenment.org/develop/api/efl/ui/win/event/delete_request

So with the C example there I could maybe catch the window delete 
request and react to it.

But, I'm to tired of "guessing" how the C++ way to call something could 
look like. Yes, I look in the .eo class file, than into the headers. 
Then I guess something from compiler output....

But here again I don't find the correct C++ way of setting up the 
efl::Win event handler callback without documentation or an example. :-(
