The nvim process isn't closed when goneovim exit by 'close' button

[damanis]

OS: LInux

• Open ~/.bashrc in goneovim: goneovim ~/.bashrc
• Closed the goneovim windows by 'close' button of main window
• Check nvim process: ps ax | grep nvim | grep bachrc
  Problem: the nvim process still exists.

Seems, need notify nvim process about exit.
Also, need to let user save changes (nvim provides confirm qa command).

I tried this patch. It works when file saved, but goneovim window stucks if file has unsaved changes.

Thanks for this report!
I was inspired by your patch and have created a patch to remedy this issue.

I tried this patch. It works when file saved, but goneovim window stucks if file has unsaved changes.

Upon investigation of the above problem, the reason for the stacks is that while nvim is waiting for user input ([Y]es or [N]o or [C]ancel), the execution of the command is not completed and goneovim is stopped in the process of select. Here, goneovim needed to send the nvim command and exit the function without waiting for it to be processed and ignore the QCloseEvent event.
