Struct WlTouch

pub struct WlTouch { /* private fields */ }

touchscreen input device

The wl_touch interface represents a touchscreen associated with a seat.

Touch interactions can consist of one or more contacts. For each contact, a series of events is generated, starting with a down event, followed by zero or more motion events, and ending with an up event. Events relating to the same contact point can be identified by the ID of the sequence.

See also the Event enum for this interface.

Trait Implementations

impl Borrow<ObjectId> for WlTouch

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

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

fn event( data: &mut D, touch: &WlTouch, event: Event, udata: &U, conn: &Connection, qh: &QueueHandle<D>, )

Called when an event from the server is processed

fn event_created_child( opcode: u16, _qhandle: &QueueHandle<State>, ) -> Arc<dyn ObjectData>

impl Hash for WlTouch

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

where H: Hasher,

impl PartialEq<Weak<WlTouch>> for WlTouch

fn eq(&self, other: &Weak<WlTouch>) -> 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.
