Implementations

impl SeatState

pub fn new<D: Dispatch<WlSeat, SeatData> + 'static>( global_list: &GlobalList, qh: &QueueHandle<D>, ) -> SeatState

pub fn seats(&self) -> impl Iterator<Item = WlSeat>

Returns an iterator over all the seats.

pub fn info(&self, seat: &WlSeat) -> Option<SeatInfo>

Returns information about a seat.

This will return None if the seat is dead.

pub fn get_pointer<D>( &mut self, qh: &QueueHandle<D>, seat: &WlSeat, ) -> Result<WlPointer, SeatError>

where D: Dispatch<WlPointer, PointerData> + PointerHandler + 'static,

Creates a pointer from a seat.

Errors

This will return SeatError::UnsupportedCapability if the seat does not support a pointer.

pub fn get_pointer_with_theme<D, S>( &mut self, qh: &QueueHandle<D>, seat: &WlSeat, shm: &WlShm, surface: WlSurface, theme: ThemeSpec<'_>, ) -> Result<ThemedPointer<PointerData>, SeatError>

where D: Dispatch<WlPointer, PointerData> + Dispatch<WlSurface, S> + Dispatch<WpCursorShapeManagerV1, GlobalData> + Dispatch<WpCursorShapeDeviceV1, GlobalData> + PointerHandler + 'static, S: SurfaceDataExt + 'static,

Creates a pointer from a seat with the provided theme.

This will use CursorShapeManager under the hood when it’s available.

Errors

This will return SeatError::UnsupportedCapability if the seat does not support a pointer.

pub fn get_pointer_with_data<D, U>( &mut self, qh: &QueueHandle<D>, seat: &WlSeat, pointer_data: U, ) -> Result<WlPointer, SeatError>

where D: Dispatch<WlPointer, U> + PointerHandler + 'static, U: PointerDataExt + 'static,

Creates a pointer from a seat.

Errors

This will return SeatError::UnsupportedCapability if the seat does not support a pointer.

pub fn get_pointer_with_theme_and_data<D, S, U>( &mut self, qh: &QueueHandle<D>, seat: &WlSeat, shm: &WlShm, surface: WlSurface, theme: ThemeSpec<'_>, pointer_data: U, ) -> Result<ThemedPointer<U>, SeatError>

where D: Dispatch<WlPointer, U> + Dispatch<WlSurface, S> + Dispatch<WpCursorShapeManagerV1, GlobalData> + Dispatch<WpCursorShapeDeviceV1, GlobalData> + PointerHandler + 'static, S: SurfaceDataExt + 'static, U: PointerDataExt + 'static,

Creates a pointer from a seat with the provided theme and data.

Errors

This will return SeatError::UnsupportedCapability if the seat does not support a pointer.

pub fn get_touch<D>( &mut self, qh: &QueueHandle<D>, seat: &WlSeat, ) -> Result<WlTouch, SeatError>

where D: Dispatch<WlTouch, TouchData> + TouchHandler + 'static,

Creates a touch handle from a seat.

Errors

This will return SeatError::UnsupportedCapability if the seat does not support touch.

pub fn get_touch_with_data<D, U>( &mut self, qh: &QueueHandle<D>, seat: &WlSeat, udata: U, ) -> Result<WlTouch, SeatError>

where D: Dispatch<WlTouch, U> + TouchHandler + 'static, U: TouchDataExt + 'static,

Creates a touch handle from a seat.

Errors

This will return SeatError::UnsupportedCapability if the seat does not support touch.
