[E-devel] Catch "delete,request" signal & shaped window

Hi,

two questions together after switching to the C++ version of the unified 
API.

How could I receive the "delete,request" signal to catch of a user 
clicks the X from the window and do something before quitting. With the 
old API I did this somehow with evas_object_smart_callback_call() if I 
remember correct.

How to I create a shaped window. Before I called elm_win_shaped_set(), 
but now I didn't find a function. Maybe I overlooked it. Is this at the 
end the same as alpha on modern systems?

regards
Andreas
