pub struct WlSeat { /* private fields */ }
Expand description
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
sourceimpl WlSeat
impl WlSeat
sourcepub fn get_pointer<U: Send + Sync + 'static, D: Dispatch<WlPointer, U> + 'static>(
&self,
qh: &QueueHandle<D>,
udata: U
) -> Result<WlPointer, InvalidId>
pub fn get_pointer<U: Send + Sync + 'static, D: Dispatch<WlPointer, U> + 'static>(
&self,
qh: &QueueHandle<D>,
udata: U
) -> Result<WlPointer, InvalidId>
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.
sourcepub fn get_keyboard<U: Send + Sync + 'static, D: Dispatch<WlKeyboard, U> + 'static>(
&self,
qh: &QueueHandle<D>,
udata: U
) -> Result<WlKeyboard, InvalidId>
pub fn get_keyboard<U: Send + Sync + 'static, D: Dispatch<WlKeyboard, U> + 'static>(
&self,
qh: &QueueHandle<D>,
udata: U
) -> Result<WlKeyboard, InvalidId>
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.
sourcepub fn get_touch<U: Send + Sync + 'static, D: Dispatch<WlTouch, U> + 'static>(
&self,
qh: &QueueHandle<D>,
udata: U
) -> Result<WlTouch, InvalidId>
pub fn get_touch<U: Send + Sync + 'static, D: Dispatch<WlTouch, U> + 'static>(
&self,
qh: &QueueHandle<D>,
udata: U
) -> Result<WlTouch, InvalidId>
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.
