Struct wayland_client::protocol::wl_seat::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: Send + Sync + 'static, D: Dispatch<WlPointer, U> + 'static>(
    &self,
    qh: &QueueHandle<D>,
    udata: U
) -> WlPointer

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: Send + Sync + 'static, D: Dispatch<WlKeyboard, U> + 'static>(
    &self,
    qh: &QueueHandle<D>,
    udata: U
) -> WlKeyboard

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: Send + Sync + 'static, D: Dispatch<WlTouch, U> + 'static>(
    &self,
    qh: &QueueHandle<D>,
    udata: U
) -> WlTouch

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 Clone for WlSeat

fn clone(&self) -> WlSeat

Returns a copy 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 PartialEq<Weak<WlSeat>> for WlSeat

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

This method tests for self and other values to be equal, and is used by ==.

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

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