Cannot detect key presses that are handled by window manager

[blokeley]

Some key presses are handled by the Windows' window manager, such as Win+x.

Is it possible to:

1. Detect those key presses?
2. Prevent the window manager from processing them?

Example code: If a winit::event::DeviceEvent::Key is detected, pass it to the following function:

pub fn on_key_event(input: KeyboardInput) {
    if input.state != ElementState::Pressed {
        return;
    }
    println!("{:?} + {:?}", input.modifiers, input.virtual_keycode);
}

Did you mean to file this in https://github.com/rust-windowing/winit/?

I thought that it might be a Windows-specific issue so might only appear in winrt-rs. If it's a winit level limitation, please let me know and I'll consider filing an issue there. It may be related to the raw device events discussion.

Agreed, this seems to be a question directed at winit rather than Rust/WinRT.

FWIW, I'd advise against overriding system hotkeys. I also don't believe there's a way to prevent the system from receiving the keys. If you really need to detect the key-press for some reason, you should look into SetWindowsHookExW. However it won't stop the system from responding to it as well.
