Winit: CloseRequested not fired

[Zenthae]

The CloseRequested event doesn't seems to be fired when winit is used without window.

OS : Windows
Winit: 0.23
Rust: 1.46

If there's no window there's no close requested, since it's for a window.

then there is no way to execute code before the app exit ? like saving data. Do i need to use another crate ?

Depends on your platform. On Windows you can use run_return instead of run.

[kchibisov]

Use run_return and what's the point of using winit (windowing toolkit), without a window?

key and mouse event listener

key and mouse event listener

It won't work cross platform though, on some systems you don't have key events without a window. If the goal is to write key logger platforms API may suit a bit better.

i just need it to work on Windows, and using something like winapi wasn't possible because i simply wasn't able to understand how to use it,

[kchibisov]

Then using run_return is fine for you.

The LoopDestroyed event exists for exactly this purpose. It is guaranteed to be emitted and guaranteed to be the last event emitted.
