Provided Methods

fn keymap(&mut self,
          evqh: &mut EventQueueHandle,
          proxy: &WlKeyboard,
          format: KeymapFormat,
          fd: RawFd,
          size: u32)

keyboard mapping

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

fn enter(&mut self,
         evqh: &mut EventQueueHandle,
         proxy: &WlKeyboard,
         serial: u32,
         surface: &WlSurface,
         keys: Vec<u8>)

enter event

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

fn leave(&mut self,
         evqh: &mut EventQueueHandle,
         proxy: &WlKeyboard,
         serial: u32,
         surface: &WlSurface)

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.

fn key(&mut self,
       evqh: &mut EventQueueHandle,
       proxy: &WlKeyboard,
       serial: u32,
       time: u32,
       key: u32,
       state: KeyState)

key event

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

fn modifiers(&mut self,
             evqh: &mut EventQueueHandle,
             proxy: &WlKeyboard,
             serial: u32,
             mods_depressed: u32,
             mods_latched: u32,
             mods_locked: u32,
             group: u32)

modifier and group state

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

fn repeat_info(&mut self,
               evqh: &mut EventQueueHandle,
               proxy: &WlKeyboard,
               rate: i32,
               delay: i32)

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.
