Struct WlSeat 

pub struct WlSeat { /* private fields */ }

group of input devices

A seat is a group of keyboards, pointer and touch devices. This object is published as a global during start up, or when such a device is hot plugged. A seat typically has a pointer and maintains a keyboard focus and a pointer focus.

See also the Event enum for this interface.

Implementations

impl WlSeat

pub fn get_pointer<U, D: 'static>( &self, qh: &QueueHandle<D>, udata: U, ) -> WlPointer

where U: Dispatch<WlPointer, D> + Send + Sync + 'static,

return pointer object

The ID provided will be initialized to the wl_pointer interface for this seat.

This request only takes effect if the seat has the pointer capability, or has had the pointer capability in the past. It is a protocol violation to issue this request on a seat that has never had the pointer capability. The missing_capability error will be sent in this case.

pub fn get_keyboard<U, D: 'static>( &self, qh: &QueueHandle<D>, udata: U, ) -> WlKeyboard

where U: Dispatch<WlKeyboard, D> + Send + Sync + 'static,

return keyboard object

The ID provided will be initialized to the wl_keyboard interface for this seat.

This request only takes effect if the seat has the keyboard capability, or has had the keyboard capability in the past. It is a protocol violation to issue this request on a seat that has never had the keyboard capability. The missing_capability error will be sent in this case.

pub fn get_touch<U, D: 'static>(&self, qh: &QueueHandle<D>, udata: U) -> WlTouch

where U: Dispatch<WlTouch, D> + Send + Sync + 'static,

return touch object

The ID provided will be initialized to the wl_touch interface for this seat.

This request only takes effect if the seat has the touch capability, or has had the touch capability in the past. It is a protocol violation to issue this request on a seat that has never had the touch capability. The missing_capability error will be sent in this case.

pub fn release(&self)

release the seat object

Using this request a client can tell the server that it is not going to use the seat object anymore.

Trait Implementations

impl Borrow<ObjectId> for WlSeat

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WlSeat

fn clone(&self) -> WlSeat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WlSeat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for WlSeat

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Weak<WlSeat>> for WlSeat

fn eq(&self, other: &Weak<WlSeat>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
