Hi,
I’m trying to get keyboard input working correctly in the IronRDP project under Sway/Wayland (Devolutions/IronRDP#535 (comment))

Could you please let me know if the following keyboard handling implementation looks correct?
https://github.com/Devolutions/IronRDP/blob/master/crates/ironrdp-client/src/app.rs#L173-L228

I’ve also tried using the latest winit beta crate, but I’m still unable to pass certain keys (e.g., arrow keys) to the IronRDP window. I’m seeing the same issue with the Meta key (which I also use for Sway).

Any guidance would be appreciated.

Can you just do WindowEvent::KeyboardInput { event, .. } => { dbg!(&event). and also run with WAYLAND_DEBUG=1.

Maybe you never get arrows because they are captured by compositor.

You can print all the keyboard events and see what is reaching you and what is not.

I did this and pressing arrow keys gives zero debug info.

Thank you @kchibisov. Debug is clearly showing that events reach the window so the problem has to be in the code.

[crates/ironrdp-client/src/app.rs:267:17] &event = KeyEvent {
    physical_key: Code(
        ArrowRight,
    ),
    logical_key: Named(
        ArrowRight,
    ),
    text: None,
    location: Standard,
    state: Pressed,
    repeat: false,
    text_with_all_modifiers: None,
    key_without_modifiers: Named(
        ArrowRight,
    ),
}

        ArrowRight,

    text: None,
