Variants

Keymap

keyboard mapping

This event provides a file descriptor to the client which can be memory-mapped to provide a keyboard mapping description.

Fields of Keymap

format: KeymapFormatfd: RawFdsize: u32

Enter

enter event

Notification that this seat's keyboard focus is on a certain surface.

Fields of Enter

serial: u32surface: WlSurfacekeys: Vec<u8>

Leave

leave event

Notification that this seat's keyboard focus is no longer on a certain surface.

The leave notification is sent before the enter notification for the new focus.

Fields of Leave

serial: u32surface: WlSurface

Key

key event

A key was pressed or released. The time argument is a timestamp with millisecond granularity, with an undefined base.

Fields of Key

serial: u32time: u32key: u32state: KeyState

Modifiers

modifier and group state

Notifies clients that the modifier and/or group state has changed, and it should update its local state.

Fields of Modifiers

serial: u32mods_depressed: u32mods_latched: u32mods_locked: u32group: u32

RepeatInfo

repeat rate and delay

Informs the client about the keyboard's repeat rate and delay.

This event is sent as soon as the wl_keyboard object has been created, and is guaranteed to be received by the client before any key press event.

Negative values for either rate or delay are illegal. A rate of zero will disable any repeating (regardless of the value of delay).

This event can be sent later on as well with a new value if necessary, so clients should continue listening for the event past the creation of wl_keyboard.

Only available since version 4 of the interface

Fields of RepeatInfo

rate: i32delay: i32
