pub enum Event { Keymap { format: WEnum<KeymapFormat>, fd: OwnedFd, size: u32, }, Enter { serial: u32, surface: WlSurface, keys: Vec<u8>, }, Leave { serial: u32, surface: WlSurface, }, Key { serial: u32, time: u32, key: u32, state: WEnum<KeyState>, }, Modifiers { serial: u32, mods_depressed: u32, mods_latched: u32, mods_locked: u32, group: u32, }, RepeatInfo { rate: i32, delay: i32, }, }

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Keymap

Fields

§format: WEnum<KeymapFormat>

keymap format

§fd: OwnedFd

keymap file descriptor

§size: u32

keymap size, in bytes

keyboard mapping

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

From version 7 onwards, the fd must be mapped with MAP_PRIVATE by the recipient, as MAP_SHARED may fail.

§

Enter

Fields

§serial: u32

serial number of the enter event

§surface: WlSurface

surface gaining keyboard focus

§keys: Vec<u8>

the currently pressed keys

enter event

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

The compositor must send the wl_keyboard.modifiers event after this event.

§

Leave

Fields

§serial: u32

serial number of the leave event

§surface: WlSurface

surface that lost keyboard focus

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.

After this event client must assume that all keys, including modifiers, are lifted and also it must stop key repeating if there’s some going on.

§

Key

Fields

§serial: u32

serial number of the key event

§time: u32

timestamp with millisecond granularity

§key: u32

key that produced the event

§state: WEnum<KeyState>

physical state of the key

key event

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

The key is a platform-specific key code that can be interpreted by feeding it to the keyboard mapping (see the keymap event).

If this event produces a change in modifiers, then the resulting wl_keyboard.modifiers event must be sent after this event.

§

Modifiers

Fields

§serial: u32

serial number of the modifiers event

§mods_depressed: u32

depressed modifiers

§mods_latched: u32

latched modifiers

§mods_locked: u32

locked modifiers

§group: u32

keyboard layout

modifier and group state

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

§

RepeatInfo

Fields

§rate: i32

the rate of repeating keys in characters per second

§delay: i32

delay in milliseconds since key down until repeating starts

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

§

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
