Struct input::event::tablet_pad::TabletPadRingEvent

pub struct TabletPadRingEvent { /* fields omitted */ }

A status change on a tablet ring with the DeviceCapability::TabletPad capability.

Methods

impl TabletPadRingEvent

pub fn number(&self) -> u32

Returns the number of the ring that has changed state, with 0 being the first ring.

On tablets with only one ring, this function always returns 0.

pub fn position(&self) -> f64

Returns the current position of the ring, in degrees counterclockwise from the northern-most point of the ring in the tablet's current logical orientation.

If the source is RingAxisSource::Finger, libinput sends a terminating event with a ring value of -1 when the finger is lifted from the ring. A caller may use this information to e.g. determine if kinetic scrolling should be triggered.

pub fn source(&self) -> RingAxisSource

Returns the source of the interaction with the ring.

If the source is RingAxisSource::Finger, libinput sends a ring position value of -1 to terminate the current interaction.
