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.
With the new API, we have an explicit lifecycle definition. I don't remember
how it is defined in C++, but in C, we do have a macro EFL_MAIN_EX() which
will call the following function:
- efl_main: at startup just before the main loop start
- efl_terminate: when the application is closed
- efl_pause: when the application can reduce is paused (on desktop this is
related to being minimized)
- efl_resume: the inverse of pause to get things back to speed
Yes, I just ask this as I run a very special mainloop in my application.
I've my own mainloop logic and just start EFL with elm_init() in one of
my threads. For various reasons I couldn't give main control in my
application startup logic to EFL.
With the old API I just catched the window delete request and ended the
mainloop with elm_shutdown() and elm_exit(). This worked great.

Oh, I see. In that case, you would have to reimplement the content of
EFL_MAIN_EX
to match your need. It is only a few lines of code and it should be possible to
tailor it to your need. You can check the content of the macros in
src/lib/ecore/efl_general.h .
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. :-(
